In many cases, some people call optical fiber transceivers photoelectric converters. There is indeed his reason. Optical fiber transceivers are a process of photoelectric conversion.

　　If you want to know how to use the function of optical fiber transceiver or photoelectric converter, you must first know what kind of function it has. In simple terms, the function of fiber optic transceivers 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 connector), and vice versa. The process is roughly as follows: convert the electrical signal into an optical signal, transmit it through an optical fiber, convert the optical signal into an electrical signal at the other end, and then connect to routers, switches and other equipment.

　　Therefore, fiber optic transceivers are generally used in pairs. One transmitter and one receiver. For example, the optical transceiver (may be other equipment) in the computer room of the operator (Telecom, China Mobile, China Unicom) and the optical transceiver used in your home, if you want to use the optical transceiver to build your own local area network, it must be to use.

　　The general optical fiber transceiver is the same as the general switch. It can be used when it is powered on and plugged in, and no configuration is required. Optical fiber socket, RJ45 crystal plug socket.

　　However, pay attention to the transmission and reception of optical fibers, one for receiving and one for sending, if not, replace each other.
