How to choose SFP transceiver for fiber optical cable

hi in this video we're going to talk about how to choose the sap transceiver the sap transceiver is critical in the fiber optical system it will determine what kind of fiber optic cable we can use like the single mode multiple and what kind of fiber optic connector we can use like LC SC or St first let's see where we need to place the sap transfer this is a very typical fiber optical system we just use the pre-mix 5 optic cable to connect the Ponte and point B so the cameras live and here we have two components which is called media converter you see this is the five of the cable and we cannot connect these five optic cable directory to our IP device such like this router or the never really recorded so we'll need this video converter to convert the five of the signal to electronic signal So eventually you can have the r345 network Port output from the media converter and this is the sap transceiver let's just remove it from the media converter foreign to the media converter then we can install the five of the cable and just connect the fabric cable to the sap transceiver is there any other place we also will need this sap transceiver let's take a look at this switch this is the regular switch because some address of our Network Port which allow us to work with the like the cafe uk6 internet cable directory and here we got some sap slot you can see it's also empty so in order to connect the switch to other Pawn by using the fiber optic cable we also need the sap transceiver okay we do know the sap trans zero will allow us to use the five optic cable on the network device let's see what kind of sap transceiver we have in the market here we have the sap plus transceiver and the sap transceiver these two are the sap plus chains 0. the speed of this transceiver can support 10 gigabyte per second and for the sap transceiver the speed is 1.25 gigabyte per second the first thing to choose to choose the chancellor is about the speed unlike this r345 network blockers we can automatically downgrade so let's say if you have the device slider camera the fan the speed of the interface just 100 megabytes per second it will work with this port even it supports 1000 megabits per second because it will automatically downgrade to work with the camera but for the sap slot that's not the case so you need to read the specification of this the speed of this sap slot this one it only work with the 1.5 gigabyte per second so if your sap transceiver for this one if it's just 100 megabytes per second you can insert in you can power up but it will not work you will not see the linking negotiation you see no linking between these two chains 0 because the speed doesn't work it relates it to the software so it will not automatically downgraded this is different from the network port the second thing is about the table you see we have single mode multi mode and this is the multiple cable and these two are the single mode so when you check choose the trans zero you need to see what kind of cable you plan to use if you plan to use the model mode then the transfer need to support multi mode but if not or with the single mode because the diameter of the code I mean the diameter of the code inside are different so when you connect the cable to the connector it will not match this is single mode okay now the next thing is about the connector here we've got the typical connector we got is about the LC scst but St they have the rocker but here we've got two kinds it's LC and the SC you see for the LC it's only about half size of the SC now we prefer the LC the reason is it's more compact it will save more space so it will be okay if you just use single media converter you may say the same space is not important but let's imagine if you are using like the switch this switch now we've got multiple sap slots right you connect many five optic cable then that space will become very important okay here we go to kind of transceiver and you see this trans people only have single part and this changer will have a multi-pot usually we need two fiber optic cable like this two to transmit and receive the data but you'll be wondering why we just have single part that's curious right the reason is this we call bidi transceiver it will use different wavelength so you just need single fibrantic table it's enough to transmit and receive the data it saves the fiber decode especially you have multiple fiber optic cable coming outside to your switch that would be great and I think that the one more thing is about temperature you see usually the device this kind of device we decided it was expecting you place this this device in a rock with the AC air condition control so that the environment should be good but some of the applications like this thing you may place outside so when you choose the transceiver you can pick the transceiver which can stand that wide range temperature so even the temperature grew up or drop down it was still working that's very important people usually mixing about the temperature and just one more thing it's by the protocol so all the all those device are using the general protocol also say open protocol but if we are working with the specific equipment like the founder Cisco you may need to choose the chain zero which if the compatible with the Cisco because they have additional information adding to the chain zero if you're just using the transceiver from the general protocol if not identified so it will not work all right that's all for today's video if you have any question please post in the comment section below see you next time
