Introduction to Fiber Optic Transceivers

Optical fiber transceiver is an Ethernet transmission medium conversion unit that exchanges short-distance twisted pairs to pair electrical signals with long-distance optical signals. Also known as a photoelectric converter in many places. This product is generally used in the actual network environment, where Ethernet cables cannot be covered, and optical fibers must be used to extend the transmission distance. It is usually positioned at the access layer to apply optical fiber broadband metropolitan area networks; at the same time, it helps to connect the last mile of optical fibers. to the city. Local area networks and extranets also play a huge role.

Simply put, the role of the fiber optic 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: convert the electrical signal into an optical signal, transmit it through an optical fiber, and then convert the optical signal into an electrical signal at the other end, and then connect it to routers, switches and other equipment.
