Optical transceiver introduction A pair of optical fibers are connected to the optical transceiver, one is for receiving and the other is for improvement. The receiving optical fiber socket is marked with RCV, and the transmitting optical fiber socket is marked with XMT. The interfaces of the two buildings must be connected. Yes, one end of the same optical fiber is inserted into the "transmit" socket, and the other end is connected to the "receive" socket. Generally, the multi-mode fiber is used for the distance within 2 kilometers, and the single-mode fiber is used for ultra-large over 2 kilometers. The optical fiber uses a laser as the signal source, so when connecting the optical transceiver, in fact, pay attention to safety. Never look at the light emitted from the optical fiber directly with your eyes. This laser beam will harm the human eye and be on the retina. Leave spots. Use the optical fiber with the connector, gently walk into the socket and then rotate it until the bayonet on the connector is tight with the socket. After inserting the optical fiber cable, connect the double comparison cable. Finally, connect the power supply, and after the correct connection, TX LINK, FX LINK and other indicator lights will light up.

Optical transceivers are devices that interconnect twisted pairs and optical fibers. Because optical fibers can transmit a long distance, optical fibers are often used when connecting the network between two buildings in the network, and twisted pair connections are used in the building. This requires a device that can interconnect twisted pairs and optical fibers, and convert electrical and optical signals to each other. This is the optical transceiver.
