Introduction to the use of optical transceiver

July 08 , 2021

Because the maximum transmission distance of the network cable (twisted pair) we often use has great limitations, the maximum transmission distance of the general twisted pair is 100 meters. Therefore, when we are laying out larger networks, we have to use relay equipment. Of course, other types of lines are used for transmission. Optical transceiver is a good choice. The transmission distance of optical fiber is very long. Generally speaking, the transmission distance of single-mode fiber is more than 10 kilometers, and the transmission distance of multi-mode fiber can reach up to 2 kilometers. When using optical fibers, we often use optical transceivers:


If you want to know how to use optical transceivers, you must first know what the optical transceivers do. Simply put, the role of the optical transceiver is the mutual conversion between optical signals and electrical signals. 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 is roughly as follows: the electrical signal is converted into an optical signal, transmitted through the optical fiber, and then the optical signal is converted into an electrical signal at the other end, and then connected to routers, switches and other equipment.

our goal is to provide optical fiber products with a high level of design quality and production integrity and have passed stringent testing.


Therefore, optical transceivers are generally used in pairs. For example, the optical transceiver (maybe other equipment) in the computer room of the operator (Telecom, China Mobile, China Unicom) and the optical fiber transceiver of your home. If you want to build your own LAN with optical transceivers you must use them in pairs.


The general optical fiber transceiver is the same as the general switch. It can be used after powering on, and no configuration is required. Optical fiber socket, RJ45 crystal plug socket. But pay attention to the transmission and reception of optical fibers, one for receiving and one for sending, and if it doesn't work, change each other.
