forcing my kids to make Ethernet cables // FREE CCNA // EP 11

you know what we're doing today no you're making me a cable i'm teaching my daughters how to make an ethernet cable i think everyone should know how to do this don't throw right thing at me it should be required learning in schools and if you're getting into i.t or getting your ccna this is a rite of passage don't skip this so in this video my girls are going to make an ethernet cable and you're going to as well or at least i'll show you how to do it we're going to walk through every step of how to make an ethernet cable [Applause] and do a fun little project to help us remember how to make one but we're not going to stop there you see ethernet cables are amazing the way they work and we're going to explore that we're going to cut it open and see hey man how do these things work isn't it beautiful so you ready let's do this and if you're studying for your ccna this covers exam objective 1.3 and thank you to the sponsor of this video and the ccna series bozon software bozon by far makes the best learning resources for the ccna ccnp so whether you want uh labs a practice exam courseware they got you covered link below and also at the end of the video i'll have a few questions from the practice exam i can never say that right practice exam there we go and we'll see if you know the contents of this video anyways let's go now we'll start with this why do we even need to make ethernet cables because they come like this like you can buy these at the store and that's the recommended way why do we have to make them i mean this is a fresh cable let me unwrap it right now well sometimes you might have people come up and just cut your ethernet head off please be careful uh happens all the time and then you cut it again no no get out of here give me those scissors no you're not cutting now seriously there are legit reasons to make your own ethernet gable i mean this would be a legit reason but still doesn't happen very often unless you have kids in your house like me but most the time when you make your own ethernet cable you're either running cable in your home or in your business for your company and you need custom links like this right here is a 5 foot ethernet cable you can find 10 feet 100 feet 50 feet like whatever but sometimes you need custom links and that's where making your own cable is the most economical way to do that so here's what i want you to do real quick do it with me go find the ethernet cable plug into your modem or your computer or whatever the thing that gives you internet take it like this find a pair of scissors and do that because now you are forced to learn how to make your own cable now seriously don't do that unless you have the supplies to make your own cable speaking of which what do you need to make your own cable here we go now of course the first thing we'll need is some ethernet cable i'm going to be rocking some cat5e utp cable this is what i would recommend it's the most common cable you'll find out there so at minimum cat5e the next thing you'll need is a crimper this tool will help us cut our cable and crimp down the ethernet heads and speaking of which we'll need some ethernet heads some good ol rj45 ethernet heads you can pick all these up at amazon home depot wherever now this is completely optional but having a good ethernet cable tester will save you some serious headaches they're not too expensive and they are worth it and i'll show you how to use it too they're pretty fun and finally things that are not optional at all first you're gonna want some coffee let's go ahead and make some right now [Music] wow [Music] and the second thing that's totally not optional is you'll need a couple of kids to do all the work for you so now with our supplies our coffee and my two kids let's get going now i do want to clear this up real quick when people say hey i want you to make an ethernet cable what they really mean is they want you to put new ethernet heads on the ends which you might go well that's that's pretty easy right no i mean it can be once you do it a few times but it does take a bit of practice but it's not too bad i'll walk you through it right now so step one take your cable should look something like this if it still has a head on him then cut off his head i'm gonna do a clean cut just for fun here there we go nice and clean guillotine guillotine off with her head hard here oh okay here we'll do it together okay okay ready we'll cut right here ready go bam now look inside there what do you see i see blue white you can see those wires sticking their heads out ready to come out so let's make them come out step one is that we want to remove about half an inch of the sheath from this cable when i say sheath i mean just the the jacket the covering covering those internal wires a half an inch is fine an inch is also fine if you are doing it for your first time it'll be helpful so here's what we're going to do notice on my crimping tool i've got two cutting options one for off with her head situation is my guillotine the other i have a little slot with the blade right above it perfect for an ethernet cable just to slide right in there so i'm going to slide that in right up to the point where i want to cut it but i'm not going to cut it calm down don't do that all you want to do at this point is kind of scratch the sheath a little the technical term is scoring it but all you really want to do is just barely scratch it because you don't want to hurt the metal cables or the copper wires inside if you look at my cable just a few scratches no big deal and that's what you want so now with our scratches there we're going to start bending it notice how when i bend it bam it's exposed it's happening it's easy [Music] it's separating back and forth until until it's gone until you can pull off his pants that's what my my daughter's called and once you have that broken you can pull off the pants completely there we go now isn't that gorgeous well first of all let me get the grandma hair out of there that's also what my daughters called it we have four twisted pairs of wires eight colorful wires they're amazing they're beautiful they're magical why because think about it these wires right here they're how you're watching this video right now literally electrical signals are going across this wire or wires like this and that's how you're watching me that's amazing but how does it do that how does it work let's talk about it i want to take a moment here and dive in get geeky get nerdy and talk about how ethernet cables actually work where they came from now if all you care about right now is making a cable that's fine i've got time stamps go ahead and skip ahead but right now we're going to dive deep how does this sucker work let's talk about it okay here we go are you ready uh the first thing i'm going to do is make this cable naked for science of course i'm going to take off the rest of the sheath or the ethernet cable jacket just going to scar the rest of the stuff here and try to get it off now if you really truly want to make a cable don't do this the sheath is there for a reason ah there it is the cable and all his glory let's get the grandma hair out of there look at it isn't it beautiful if you've never done this before then go ahead and do it right now you should now of course the reason we have the sheath or the jacket is to protect our cable keep him nice safe and secure in his little jacket but it doesn't protect him from everything you see ethernet cables do have enemies an archenemy called emi or electromagnetic interference any other device that has swiftly changing electrical currents emits emi now that can be and is a lot of stuff in your house or your business this jacket over here does little to protect from it but not all is lost you see notice our wires they're not just like sitting still chilling right they're twisted together which might be a little strange like why are they twisted together why are they doing that emi twisting those wires together actually helps protect against emi and notice they're twisted into pairs an emi is not the only enemy to the ethernet cable the other enemy would be crosstalk electrical signals are going across these wires and if they weren't twisted if they're just running parallel to each other there'd be a lot of crosstalk and interference but by twisting them together we can actually avoid that for the most part so because this cable is unshielded he only has a jacket on and he's twisted he has twisted pairs we call him a utp cable which stands for unshielded twisted pair now this cable does have a stronger older brother named stp or shielded twisted pair and he's not just wearing a jacket he's got another layer another legit shield that protects from emi now he's used in like very serious circumstances like factories and places where there's a ton of emi so for the most part if you're just using your cables in your business or your home that's when you're going to see mostly utp cable unshielded twisted pair now before we untwist these wires one thing to note the jacket that he's wearing they come in different types like this one right here it's an okay jacket great to run in your house but if i were to run this into like maybe a ceiling or a place where there might be a fire hazard you don't want to use this type of cable if it were to burn it does emit toxic chemicals so there are other types of cables with a different type of jacket plenum cables that are designed to be run in those very specific situations so enough about the jacket let's get that out of here we don't care about that let's unswitch the cables and talk about what's actually happening under the hood inside our cables i mean he's already naked right let's uh untwist the pairs here it's actually a pretty huge pain to do this come on oh there we go that works yeah okay now we have our untwisted pairs that gave them a bit of a haircut so we can see them better now what's going on with these i mean this is the guts of our ethernet cable what's actually happening under the hood or inside the jacket i guess jackets have hoods i don't know let's keep going so these are copper wires copper because it's really great at conducting electricity right and that's what's going to be flying through these coffee break now also notice there are eight total wires and they're paired up we got the orange brothers orange and white orange the blues brothers ah didn't mean to do that white blue and blue the green brothers and the brown brothers four total pairs and normally they are twisted together right these eight copper wires make up a cable we know and love it's our category 5e cable or cat 5e for short his official name is the 1000 base t cable and this cable's awesome i mean he's fast he goes at gigabit speeds but before we talk about how he runs how he works i feel like we need to go back in time a bit to truly appreciate how far we've come and to understand why it's so cool what we have now i mean really it truly is so to do that we're gonna have to actually take away a few of these copper wires you'll understand why i'm doing that here in a moment but right now we have eight and that helps us go freaking fast but once upon a time we were four shy down by half this type of cable with only four measly wires was what we had for a long time and it in those days it was fast like back in my day this is what we had let's talk about it yes we're still dealing with copper wires but we only have four now two pairs and the first standard we're going to look at circa 1990 one year after i was born 10 base t blazing fast for its day the 10 indicates the speed of the cable 10 megabits per second the t stands for twisted pair which would also indicate that it's going to be using copper copper wires now the copper wires in this cable were kind of old we call these cat 3 wires or category 3. and that's one thing people don't know when we say cat5 or cat 5e or cat6 we're not referring to the entire ethernet cable we're referring to the individual wires the copper wires so in the 10 base t cable cat 3 wires 4 total wires giving us a blazing 10 megabits per second speed and then as we go forward in time a few standards later 1995 good year toy story right i think yeah and comes 100 base t and actually tx to be precise now how fast does this go well if you're paying attention it's right here it goes 100 megabits per second which for its time was like what and i can't write while i'm looking at the camera that's crazy and again the t standing for twisted pair and that means copper now i'm pointing that out because you'll often see other notations like lx or s and that will actually mean fiber but that's a topic for another time now this cable often goes by a different name as well this is fast ethernet cable when we refer to anything that uses 100 megabits per second when we say oh yeah there's a fast ethernet port that's a fast ethernet cable and it was fast ethernet for the time now what made it faster than 10 base t well it wasn't the number of wires we still had four wires but it was the type of wires we used we went from cat 3 to cat5 now let's get a bit more nerdy both of these cables worked in a similar way now again these copper wires have electricity flowing through them which is why they're in pairs each one of these is a closed loop an electrical circuit allowing electricity to flow now this is cool but you might be wondering okay fine the wires are a pair they form an electrical circuit but how is that sending me my youtube video how is this working right now watch this let me get this other stuff out of the way and we'll talk about it now i am going to oversimplify things here a bit but you know that computers talk to each other in binary right ones and zeros and i'm not saying anything right now so i'm just just writing right and the computer will take those ones and zeros and turn it into this youtube video you're watching right now but how does an electrical signal communicate a bunch of ones and zeros like this watch this and i stole this example from this article i read on this and it's just fantastic if you want to dive deeper than what i'm doing right now read this article link below let's say that we want a binary one communicated across the ethernet cable these wires to do that they'll simply change the voltage that they're sending across the wire so for example the electrical currents flowing on this cable right or these wires let's say it sends 2.5 volts down the wire the other end will go oh okay that's a one it's kind of like shock therapy let's say they wanted to send a zero down the wire a binary zero well they would maybe send a negative 2.5 volts down the wire oh not as bad that's a zero now again this is way oversimplified this happens a million times with varying voltages and encoding schemes but that's basically the big idea changing the voltages in the electrical current to communicate data that's amazing if you're if you're that's amazing then why are you even here anyways now let's step back a bit and start talking again about 10 base t and 100 base tx with these standards let me write them up here again one pair of wires was used to send data which we often see abbreviated as tx has nothing to do with the tx up here so ignore that stands for transmit and the other pair of wires was dedicated to receiving or rc now this is crazy important to know i'll show you why here in a second and it's also the reason we color code our wires let me show you why i'm going to introduce a new character into the story here mr rj45 everyone say hello this is our rj45 ethernet header it's what we'll plug these wires into it's the end that's what we terminate them to let me give each side one i mean i don't have to tell you too much about these you know these you love these you love the sound it makes when you plug them into a switch oh yeah they're great but just a few things inside this ethernet head this rj45 jack are eight pin outs eight places for a wire to be inserted into and notice in these pen outs there's a bit of metal so it actually can conduct the electricity and send that those bits and data streams into your computer but now we're getting to the interesting part the fun part where we actually have to know how to build a cable how we structure a cable and if we don't then it ain't gonna work so i'm gonna draw an ethernet head pin out over here again there are eight pin positions eight pens i'm gonna get this stuff out of the way too just for the time being now let's talk about a raspberry pi i love talking about raspberry pi's but what does it have to do with this well like most pcs and end devices it has built into it an ethernet nic or an ethernet network interface card like right here it hasn't a port to plug in an rj45 cable i mean that's not new to you right your laptop your computer has these or maybe not your laptop anymore but definitely your computers your desktops now here's the important part this raspberry pi and all computers and things like it all in devices its network interface card is programmed to send data on pins one and two so every time it attempts to send anything it sends it down pens one and two and then when it wants to receive something it'll receive things on pins three and not four like you might think six three and six let me label those real quick transmit and receive so it's at this point where it becomes very very important how we put our copper wires inside this ethernet header so let me insert these into our little diagram here gotta use some tweezers for this this is very delicate work here i'm gonna slide my pins into the diagram here or my wires into the diagram here white orange and the pen one orange and the pen too white blue and pen three this will be our receiving pen or our receiving wires and blue into pen six now if mr pi here is sending something on these wires well he's sending it to somebody right there's got to be something on the other end and there is so let's add my other ethernet header here at the other side and most often what's on the other side of the endpoint what do we plug things into a switch yep you got it it's a switch let's draw that real quick a switch with lots of ethernet ports now it might appear at first that we have a problem here because the ethernet nic and the raspberry pi is sending data on pins one and two does the switch also send data on pins one and two because i thought if that were the case like there would be a traffic jam no that's not the case he switches because they are normally being connected to end devices endpoints they change it up switches will receive data on pins one and two and you probably guessed it they'll send data on pins three and six to match up so they'll send data on pins three and six and guess what the host receives the data on pens three and six perfect that's how the pins are programmed in the switch and that's how the pins are programmed in the ethernet on the raspberry pi now this right here the way we've arranged our copper wires inside our pins are pin outs this is called a straight through design or you might hear it called a straight through cable it is by far the most common cable you'll see it's the one we're making in this video and it makes sense like we connect our endpoints our pcs to switches and that calls for having the copper wires to be in the same positions on each side one to one two to two three to three six to six but let me kick you a scenario real quick and actually as i'm saying that i'm realizing i did something wrong here if you want to properly make a 10 base t or 100 base t x at my x back in there if you want to properly make one of those cables you got to have the colors right the way we put our colors in order is extremely important right now i'm rocking white orange orange white blue blue orange is fine but the blue does not match up i want to take blue out i want you to be able to walk away from this video and confidently say yes i can make a 10 base t cable if anything so commonly we're going to be using green in our 10 base t and 100 base tx cables so let me scoot those guys in there that's going to be white green at pen position 3 and green at pen position 6. good enough but now here's my scenario what if and this does happen what if the other end was not a switch what if the device we wanted to connect our raspberry pi to was instead of a switch another raspberry pi let me scoot that in here real quick there he is now just so we're not confused i'm gonna name these guys this is gonna be uh george pi hi george and harry pi now i said interesting scenario it's more of actually a problem you see right now the way we have things connected do you think they're going to work no no they're not going to work and let me tell you why when george wants to send harry something what's he going to do we're going to send some bits some voltages down pens 1 and 2. yeah we know that but when harry wants to send george something what's he going to do well he's gonna send things down pins one and two and then things blow up because it doesn't work right george isn't listening on pins one and two and neither is harry they're both talking and no one's listening it's like my kids when they're fighting and then they're both listening on pens three and six but nothing's happening over there nothing's stocking they're sitting there silently in a room nothing's going on so if you've ever connected a straight through cable between two like devices like a pc two pcs connected together two raspberry pi's it didn't work did it at least with a fast ethernet cable 10 base ta 100 base tx now not all is lost there is a solution and it's actually pretty easy check this out all we have to do is simply cross over some cables i'm going to screw the green guys out of the way for a second i just messed them up dad got it this is really hard with tweezers and stuff i'm never doing this again so i'm gonna leave the white orange and orange wires and pen one and two on george's pie here on his pinna but instead of pin one going to pin one i'm gonna have pin one go to pen three and then pen two will go to what do you think pen six that way when george is talking to harry he's not talking to his mouth he's talking to his ears which i know is a weird thing to say but that's what's happening here he's talking to where he's listening and we'll do the same thing for harry we're gonna take his pen one and go to george's pen three that's our that's our white green cable and we'll take the green one going from harry's pen to george's pen six good enough just pretend it's reaching all the way to pin6 so now they're both talking to each other's ears and we've successfully crossed over the wires in fact that's what this type of cable is called we call this a crossover cable and again this is required when you want to connect devices that are similar so pc to pc raspberry pi raspberry pi switch to switch yeah at least you used to with fast ethernet we'll talk more about that here in a moment there's something special they do now i don't know about you but i'm tired of living in the past here let's stop talking about the old stuff let's talk about the new fast stuff the stuff we have now the cable we're making in this video the cat5e the thousand base t let's get them in here things are about to heat up because we know that we're not dealing with just four wires we're gonna be dealing with eight copper wires and i'm sure you're curious what's that look like let's talk about it let me get harry out of here now let's put our switch back in there as well because i do want to focus on the straight through cable first now i'm going to wire up my cable back to a straight through real quick i'm going to uncross my wires puts a whole new perspective on the saying you got my wires crossed just thought about that in some cases it is a good thing so now with 1000 base t our gigabit ethernet cable cat5e we know we have eight copper wires let's bring in our other players real quick coming on in brown and blue but where do they go how do we arrange these guys well i got a simple way to help you with that paint your nails you'll memorize it real quick trust me now notice the order i have the wires in for 10 base t and 100 base tx it does still match my my fingernails even though we're using four wires white orange orange white green and then green on my thumb the other fingers tell us where to put the rest of the wires for 1000 base t let's do that right after white green we're going to have blue come in and then right after blue we're going to have white blue come on guy and then lastly we'll have our brown come in white brown will come in first right after green at pen position seven and finally brown at eight and boom right here this is a cat5e straight through cable pin out just like this we know it straight through because the pins match on each side we even have a name for the way these wires are arranged it's called the 568 b pin out now i want to tell you something kind of amazing are you ready watch this we know that pins 1 and 2 are used to send traffic on an ethernet nic so tx and then pins 3 and 6 are used to receive rc but what about these new guys four and five and seven and eight what do they do well the amazing thing is it doesn't matter what do you mean the cool thing about gigabit ethernet 1000 base t cat5e cables is that they can send and receive data simultaneously did i say that right simultaneously yes on each pair of wires that means pins one and two can both send and receive at the same time so we can just call him txrc and i just realized i've been using rc like it's actually a thing it's not we typically use rx as a receiving i guess it's not receive the c in there whatever we do use rx in the networking world to refer to receiving anyways that's amazing right so it doesn't matter each pair of wires can simultaneously send and receive traffic that's part of the reason why we can get these crazy fast gigabit speeds now if we had to say what four and five do those are transmit and seven and eight are received but again with the new standard we have now it doesn't matter which one transmits receives they both do both at the same time but but i'll say this it does still matter what order we put our wires in when we create our cables if you're making a straight through cable you want to make sure that both sides are matching one to one two to two three two three four to four and you put your colors in the right order match the pin out most common one we have now is 568b now i'm gonna bring in our old friend harry once more again what if we have raspberry pi raspberry pi pc to pc again we need to cross over the cables right to make that work but how do we do that with eight cables the answer is the same way it's actually yeah it is the same way we'll cross over the same wires so i'll do that real quick and it's going to take me a second because it's this is hard you're welcome now it's a little messy i'll put up a real diagram right now but you got the gist right you cross over wires one and two three and six this pin out actually has its own name we call this the 568 a pin out so if you're looking up hey how do i make crossover cable we'll make one side 568b and the other side 568a straight through make both sides 568b or you could actually make both sides but more commonly we still see now 568b on both sides straight through that's what we'll be doing here in a moment now what if i told you i kind of wasted your time telling you about crossover cables with um a 1000 base t because i basically did according to the gigabit ethernet standard crossover cables are basically not needed and it's again it's magic it's kind of magic watch this i'm going to put these guys back into a straight through design i'm going to take george and harry out of here for a moment because i want to focus in real quick on two switches when we connect two switches together which we do often in the networking world in theory you would need a crossover cable because they send and receive on the same pins however switches are lit they're smart they're amazing we've talked about this before and they have this feature called auto mdix and what this basically means is they'll use magic or technology rather to detect what pens are being received and sent on and they'll simply just change what pins they send and receive on to match the person plugged in so if you plug your pc into a switch it'll receive a one and two send on three and six but if you plug a switch into a switch he'll change it up he'll send on one and two and receive on three and six switches have had this feature for a while even with a hundred base tx but now as part of the 1000 base t standard to be considered a gigabit ethernet nick everyone does this now i don't want to craft for this this is not the proper way to write this out i want to write it out properly just so i avoid the trolls here it's auto mdi dash x right that's how you do it okay fine now officially for any exam if they ask you hey if you can add two switches together what kind of cable is required you'll want to answer crossover they're testing you on your cable knowledge but in reality now with our 1000 base t cables and westwich has been doing for a while it doesn't matter they will automatically change what pins they send and receive on avoiding the issue altogether isn't that magic i freaking love that but you wouldn't appreciate that unless you knew where we came from unless you knew what we had to deal with before my children will never have to make a crossover cable unless i force them to which i probably will now our 1000 base t cable man he doesn't quit he's fast gigabit ethernet he only has one limitation only one i know right it's how long you can make the cable he can only go 100 meters which is a good length but if you try to make a cable longer than that which you can like you can do it if you try to go longer it won't work it just won't this cable has a limitation where the electrical signal is going across if they go past 100 meters it'll start to degrade and that basically means crappy internet it won't work very well as you're going further in the ccna you'll learn more about things this will cause what's called late collisions and this goes for 10 base t and 100 base tx don't make your cables longer than 100 meters if you want longer than that you're going to want to go for something else like maybe fiber which we'll talk about later now let's talk about the future because the future is now we do have some cool new stuff like cat6 and cat eight let's talk about that now officially cat6 which again is referring to the wires inside of your ethernet cable it's just a more reliable version of cat 5e but people want to talk about cat6 and the crazy speeds you can get from it are mainly talking about cat 6 a cat6a is exciting and crazy we call this 10g base t and if you remember why we named things the way we do you got really excited because 10g means 10 gigabits per second like that's crazy like that's not even fair that's cat 6a and again it's still using the same eight wires well not the same like the cat6a wires but it's still only eight wires and it does look different like it has like a weird thing in the middle like look at this picture here but it's freaking awesome and even more futuristic is cat eight cat eight we call this 40 g base tee and yeah i mean by no you know what i'm talking about that's just crazy 40 gigs 40 gigabits per second who needs that i do i need that i want that okay let's continue making our cable so the first thing i want to do you see this grandma hair right here let's just get her out of the way right now it's kind of annoying i'm gonna grab some regular scissors because you know regular scissors are the best things for regular hair now let's go ahead and cut that out of here ah got it and now we're going to take our twisted pairs and we're going to untwist them so untwist each pair of cables kind of a pain but not too bad now once they're untwisted what you also want to do is kind of iron them out make them very very straight it's going to make your job a lot easier here in a moment let's go ahead and do that right now kind of fan them out a bit and make them super straight now what order we put these colored wires in is very important if you don't put them in the right order then your cable just won't work so what order do they need to go in well um i've got a little reference table for you here this is the best way to memorize this just uh paint your nails easy enough time to paint some nails you think with fire girls i would have done this before okay [Music] what about my other nails your other nails sorry there's only eight strands of copper in an ethernet cable [Music] daddy so i'm going to paint that all right time to get my nails painted [Music] okay that is good it's again this is the 568b pin out that's what we're going to use for our straight through cable here so let's go ahead and do that so first we'll start with white orange get that kind of massaged and ironed with my finger right there then orange he's right there already ready to go team player next we'll have white green and i'll go ahead and scoot that guy over here now it's important as you're doing this you want to make sure that they're lined up from the bottom to the top because we're actually going to end up cutting more towards the bottom here so make sure you have it kind of tightened with your thumb there as you place each cable or wire i keep calling them cables they're wires now i had to double check and look closely that that was green because i'm colorblind and as you can imagine making cables has always been terrible for me anybody else out there colorblind anyways let's keep going tell me if i'm doing it wrong please now this is where things get weird you might think green will come after white green no not here not today after white green we're gonna have blue sneak in let's try to make things as straight as possible and again i'm just gonna kind of iron it out to make sure they stay in place and then after blue we go back to following the rules white blue comes in get green out of the way there white blue settles right in next to blue again making sure it's nice and straight from the bottom to the top my daughters actually did not make sure that was the case and um they messed up i'll show you here in a moment now after white blue green finally gets to come in and join the team so make sure he's nestled safely there and then finally we got brown so we're gonna pull in white brown first come on around brown and then white next white next right next to white brown we're going to have brown command as our final wire at this point i'm going to hold them very very tightly with my right thumb here my green thumb hey i've got a green thumb and i'm going to iron them out to where they're not going to move at all and they should look like this are they in order tell me actually they weren't blue had white blue it snuck in so i gotta fix it see attention to detail is important when making cables so here we go let's inspect closely again are we good i think this time around we are so now we're ready to trim this up a bit we're going to give it a haircut now my goal is to cut around right here about half an inch i would say so i'm going to grab my crimpers while holding this very tight and i'm going to give them a nice even buzz cut these are hard hard and your buzz cut should look something like this beautiful now don't touch it you don't want the wires to move leave them there we're going to grab our rj45 ethernet header and now it's time to slide those wires into their pin position now when you slide them in the clip on the ethernet header needs to be down like this so not up without sucker down pointing down so with white orange on the left and brown on the very far right we're gonna slide these in praying that they all slide into the right position slider and then you'll feel them kind of hit there yep there we go now this is your chance to do a last minute spot check and look through barely you can barely see right look through this and make sure the colors are lined up before we crimp it down now hang on to this tightly don't let go yet because it's going to fall out we want to use our crimpers now to crimp this down make them stay now notice this real quick part of the sheath is inside the ethernet header and that's a good thing we want that because it'll actually be clamped down through this hole right here the crimper will actually do that so let's make it happen so my crimper here yours might be a bit different but on my notice i have two sides on this side notice there's no teeth right here this is the side i'm actually going to put my header through on the other side notice there are some teeth that's what's going to clamp down those copper wires so let's go ahead and turn this back over i'm going to carefully very carefully slide this sucker through i'm going to slide it up to the point where that little metal tab right there that has 8p on it that's actually going to go into that slot on the ethernet header to clamp the shield down so you want to get those holes lined up or the the clip lined up with the hole and then it's ready to clamp i'm going to turn mine around so i can show you what happens when i clamp it you ready i'm going to squeeze the handles together and boom clamping it's clamping i'm going to do actually a few times because i'm paranoid clamp clamp clamp notice that tab's going into the hole and clamping the sheath down and now i can pull it out so now it should be pretty snug in there if i pull shouldn't come off notice the sheath is pretty clamped and boom finished product now it's okay if yours isn't like pretty if it doesn't look great at all that's fine my first few were terrible took me a good hour possibly more just to do my first cable so no worries now step two is to rinse and repeat and do the same thing on the other side there's two sides of the cable right now the other end and because this is a straight through cable you're gonna wire it up the exact same way you want both sides to match so get to work like any proper cooking show i've already got one complete i'm not gonna go make another cable this is one i made um yesterday i think yeah yesterday a little small little patch cable i love it so now that you made your cable does it work will it work well well let's test it that's what a cable testers for let's grab ours right here they're all a little bit different but they do the same thing so i'm going to take this off here this is great because it's normally meant to test cables that are already run so i could take this to an office and take this to you know a closet and see if the cable is actually working but it works well enough right here too so i'll plug one end to the main device here come on there we go and the other to the remote now notice we have the numbers one through eight those are all the pin positions the cables going in there and when i turn this on it's gonna send a little electrical signal on each wire it'll light up one two three four now because this is a straight through cable when one lights up we want one to light up on the other side too one one two two three three and if they all light up and they match we know we're good so let's go ahead and do this i want to turn it on to slow mode and fingers crossed let's see if it works one two three four five six seven eight yes okay now that's that's an example of a perfectly working straight through cable that will totally do the job now my daughter's tried this um they completed their cables and you'll notice that the numbers don't quite match up when they do their test that's fine cut it up and do it again [Music] okay quiz time i'm gonna quiz you guys and i'm gonna quiz you guys and see if you remember how to make an ethernet cable now without looking let me hold my stuff and my fingernails here addie actually close your ears addie what order do we put our ethernet cable in now look at the camera over there look at the camera over there white orange orange white green blue blue white green white brown brown good job all right chloe same for you get over here and talk to the microphone uh what's the 568b pen out for any uh ethernet cable it's what color or uh order do you put it in white orange orange white green blue white blue green white brown brown very good all right um so you passed that quiz now let's do the next quiz which colors i'm gonna hold up my fingers now here we go which colors which pins send traffic what which pins talk oh one and two good job all right which ones listen three six three and six very good job what colors are those green white blue i know what color is three and six green white and blue i mean green good job all right chloe which pins talk which colors white orange and orange one and two one two which pens listen three and six what colors are those white green i think and white blue nope i think it's right blueberry it's not three and six oh green very good job did you guys get that right let me know below and now a quiz question from bozon now this one might be a little difficult because it has some things we haven't exactly covered yet but one thing we did it was a brief mention so let's see how you do question is which of the following can cause late collisions on an ethernet lan select two choices pause the video go alright let's see how you did now a lot of these things you probably don't know what they are just yet but hey hold on a second do you know what this is long cable segments we talked about with an ethernet cable our cat5e the limitation was that you can only make it 100 meters in length and if you go beyond that if you make it longer this can cause late collisions late collisions so you know what that might be one of the answers bam now for everything else you either already knew a bit of it or you had to look it up and that's fine googling is the superpower of it professionals the answer here will be a duplex mismatch let's see if i got it right boom and duplex mismatch has to do with one side only sending half duplex and the other sending full duplex and we'll cover more on that later in this video i taught my daughters how to make a cat5e ethernet cable now do they know everything about an ethernet cable no they're still learning that's fine it's just a place to start and that might be where you're at too you may not know everything about an ethernet cable although if you watched the entire video you learned a lot i'm hoping like how they work electrical signals flowing across which wires send and receive where we came from and where we're at now mdix all kinds of fun stuff it's magic right but anyways let me know below if you were able to make an ethernet cable and you know what if you already know how get someone else to make it make your kids make them like i said i think everyone should at least know how to make an ethernet cable it's fun it's a vital part of how we live now we need the internet we need ethernet it's crazy anyways i could talk about that for a long time i'm again huge shout out to our sponsor bozon software if you want to get your ccna or your ccnp or security plus they do a bunch of stuff check out their practice exams their gold standard their their labs their courseware all of that links below i use them all the time especially for right now for my ccnps i'm studying for that and if you haven't already hit that subscribe button hit that like button all the youtubey stuff to make sure that people see this video and to show that you like it it helps support me anyways that's all i got i'll catch you guys later [Music] you
