How to use fiber optic transceivers in the network?
Fiber optic transceivers can easily integrate copper cable-based wiring systems into fiber optic wiring systems, with strong flexibility and high cost performance. Under normal circumstances, they can convert electrical signals into optical signals (and vice versa) to extend the transmission distance. So, how to use fiber optic transceivers in the network and correctly connect them to switches, optical modules and other network equipment? This article will give you details.
How to use fiber optic transceivers?
Today, fiber optic transceivers have been widely used in various industries, including security monitoring, enterprise networks, and campus LANs. Fiber optic transceivers are small in size and occupy a small space, so they are very suitable for deployment in wiring closets, chassis and other places with limited space. Although the application environment of fiber optic transceivers is different, the connection methods are essentially the same. The following describes the common connection methods of fiber optic transceivers.
Use alone
Under normal circumstances, fiber optic transceivers are used in pairs in a network, but sometimes they need to be used separately to connect copper cabling to fiber optic equipment. The fiber optic transceiver with 1 SFP port and 1 RJ45 port is used to connect two Ethernet switches. Among them, the SFP port on the fiber optic transceiver is used to connect to the SFP port on switch A, and the RJ45 port is used To connect to the electrical port on switch B, the connection method:
1. Use a UTP cable (a network cable above Cat5) to connect the RJ45 port of switch B to the electrical port on the fiber optic transceiver.
2. Insert the SFP optical module into the SFP port on the fiber optic transceiver, and then insert the other SFP optical module into the SFP port of switch A.
3. Insert the optical fiber jumper into the optical fiber transceiver and the SFP optical module on the switch A.
Used in pairs
Usually a pair of fiber optic transceivers are used to connect two network devices based on copper cabling to extend the transmission distance. This is also a common solution for using fiber optic transceivers in the network. Steps of how to use a pair of fiber optic transceivers with network switches, optical modules, fiber jumpers and copper cables:
1. Use a UTP cable (a network cable above Cat5) to connect the electrical port of switch A to the RJ45 port of the optical fiber transceiver on the left.
2. Insert an SFP optical module into the SFP port of the left fiber optic transceiver, and then insert another SFP optical module into the SFP port of the right fiber optic transceiver
3. Use fiber optic jumpers to connect two fiber optic transceivers.
4. Use a UTP cable to connect the RJ45 port of the right fiber optic transceiver to the electrical port of switch B.
Note: Most optical modules support hot-swappable, so there is no need 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; insert the optical fiber jumper after inserting the optical module into the optical fiber transceiver.
