What is the working principle of optical fiber transceiver What is the working principle of optical fiber transceiver

Transceiver is a device for signal conversion, which usually refers to optical fiber transceiver. The emergence of optical fiber transceiver converts twisted pair electrical signals and optical signals to each other, ensuring the smooth transmission of data packets between the two networks. At the same time, it expands the transmission distance limit of the network from 100 meters of copper wire to 100 kilometers (single-mode optical fiber).

First of all, let's understand what is optical fiber transceiver. Optical fiber transceiver is an Ethernet transmission media conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals. It is also called photoelectric converter in many places. After knowing what is an optical fiber transceiver, let's have a detailed understanding of the working principle and usage of the optical fiber transceiver!

Optical fiber transceivers are generally used in the actual network environment where Ethernet cables cannot be covered and optical fibers must be used to extend the transmission distance. At the same time, they also play a great role in helping to connect the last kilometer of optical fiber lines to the metropolitan area network and the outer network. With optical fiber transceiver, it also provides a cheap solution for users who need to upgrade the system from copper wire to optical fiber, and lack funds, manpower or time.

The function of optical fiber transceiver is to convert the electrical signal we want to send into optical signal and send it out. At the same time, it can convert the received optical signal into electrical signal and input it to our receiving end.

Optical fiber transceivers are generally used in pairs. For example, the optical fiber transceiver (possibly other equipment) in the computer room of the operator (Telecom, China Mobile, China Unicom) and the optical fiber transceiver in your home. If you want to build your own LAN with optical fiber transceivers, you must use them in pairs. General optical fiber transceivers, like general switches, can be used after being powered on and plugged in without any configuration. Optical fiber socket, RJ45 crystal head socket. However, we should pay attention to the receiving and sending of optical fibers, one receiving and one sending, and if not, we can exchange them.
