The optical fiber transceiver can easily integrate the copper based cabling system into the optical fiber cabling system,with strong flexibility and high cost performance.In general,they can convert electrical signals into optical signals(and vice versa)to extend the transmission distance.Then,how to use the optical transceiver in the network and correctly connect it to the switch,optical module and other network equipment?This article will elaborate for you.
How to use fiber optic transceivers?
Nowadays,optical fiber transceivers have been widely used in all walks of life,including security monitoring,enterprise network,park LAN,etc.Optical fiber transceivers are small in size and occupy a small space,so they are very suitable for deployment in wiring rooms,chassis and other places with limited space.Although the application environments of optical fiber transceivers are different,the connection methods are essentially the same.The following describes the common connection methods of optical fiber transceivers.
Use alone
Usually,the optical fiber transceivers are used in pairs in the network,but sometimes it is necessary to connect the copper cable wiring to the optical fiber equipment separately.As shown in the figure below,the optical transceiver with one SFP port and one RJ45 port is used to connect two Ethernet switches.The SFP port on the optical transceiver is used to connect with the SFP port on switch a,and the RJ45 port is used to connect with the electrical port on switch B.the connection method is as follows:
1.Use UTP cable(network cable above CAT5)to connect the RJ45 port of switch B with the electrical port on the optical transceiver.
2.Insert the SFP optical module into the SFP port on the optical transceiver,and then insert another SFP optical module into the SFP port of switch a.
3.Insert the fiber jumper into the SFP optical module on the fiber transceiver and switch a.
Use in pairs
A pair of optical fiber transceivers are usually used to connect two network devices based on copper cabling together to extend the transmission distance.This is also a common scheme for using optical fiber transceivers in networks.The steps of how to use a pair of optical transceivers with network switches,optical modules,optical jumpers and copper cables are as follows:
1.Use UTP cable(network cable above CAT5)to connect the electrical port of switch a to the RJ45 port of the left optical transceiver.
2.Insert one SFP optical module into the SFP port of the left optical transceiver,and then insert the other SFP optical module into the SFP port of the right optical transceiver
3.Connect the two fiber transceivers using fiber optic jumpers.
4.Use UTP cable to connect the RJ45 port of the right optical transceiver with the electrical port of switch B.
Note:most optical modules support hot plug,so it is not necessary to turn off the power of the optical transceiver when inserting the optical module into the corresponding port.However,it should be noted that when removing the optical module,you need to remove the optical fiber jumper first;After inserting the optical module into the optical transceiver,insert the optical jumper.
