Usage Of Optical Fiber Transceiver

- Sep 16, 2019-

Because the maximum transmission distance of the twisted pair wire (twisted pair wire) we often use is very limited, the maximum transmission distance of the general twisted pair wire is 100 meters. Therefore, when we deploy a larger network, we have to use relay devices. Of course, other types of lines are used for transmission. Optical fiber is a good choice. The transmission distance of optical fiber is very long. Generally speaking, the transmission distance of single-mode optical fiber is more than 10 kilometers, while the transmission distance of multimode optical fiber can reach up to 2 kilometers. When using optical fibers, we often use optical transceivers:

If you want to know how to use the optical transceiver, you need to know the function of the optical transceiver. Simply put, the function of optical transceiver is the conversion between optical signal and electrical signal. The optical signal is input from the optical port, and the electrical signal is output from the electrical port (common RJ45 crystal head interface), and vice versa. The process may be as follows: converting electrical signals into optical signals, transmitting them through optical fibers, converting optical signals into electrical signals at the other end, and then accessing routers, switches and other devices.


Therefore, optical transceivers are usually used in pairs. For example, the optical transceivers (possibly other devices) in the computer rooms of operators (telecommunications, mobile, Unicom) and your home optical transceivers. If you want to use optical transceivers to build your own LAN, you have to use them in pairs.

The general optical transceiver and the general switch, the power, plug-in can be used, do not need to do any configuration. Optical fiber socket, RJ45 crystal head socket. Nevertheless, we should pay attention to the sending and receiving of optical fibers. We should change each other if we can't.
