What is the difference and correlation between optical transceivers and optical transceivers?

The optical transceiver is an Ethernet transmission medium conversion unit that exchanges short-distance twisted pair electrical signals and long-distance optical signals. In many places, it is also called photoelectric converter or fiber converter (Fiber Converter). ).

The optical transceiver is a device that converts multiple E1 (a data transmission standard of a trunk line, usually at a rate of 2.048 Mbps, which is adopted in China and Europe) into an optical signal and transmits it (its function is mainly to realize electric-light and light). -Electric conversion).

The same thing:

Photoelectric conversion

the difference:

The transceiver only performs photoelectric conversion, does not change the encoding, and does not perform other processing on the data. The transceiver is for Ethernet, runs the 802.3 protocol, and is only used for point-to-point connections.

In addition to the work of photoelectric conversion, the optical transceiver also multiplexes and demultiplexes the data signals. Usually, the optical transceiver comes out of multiple pairs of E1 lines. SDH, PDH optical transceivers are mainly used by telecom operators to provide multiple pairs of point-to-point data circuits. Video optical transceivers are mainly used in security surveillance, distance education, video conferencing, etc., where video transmission requirements are relatively timely, and Transmission control, switching, voice, Ethernet and other signals to meet the needs of multi-service applications, so we sometimes call it integrated optical transceiver.
