The same thing: photoelectric conversion is required.
The difference: the transceiver only performs photoelectric conversion, does not change the code, and does not perform other processing on the data. The transceiver is for Ethernet and runs the 802.3 protocol, which is only used for point-to-point connections.
In addition to the work of photoelectric conversion, optical transceivers also need to multiplex and demultiplex data signals.
Usually optical transceivers come out to E1 lines, SDH, PDH optical transceivers are mainly used by telecom operators to provide multi-point-to-point data circuits;
Video optical transceivers are mainly used in security monitoring, distance education, video conferences and other fields that require timely video transmission. At the same time, they can transmit control, switching, language, Ethernet and other signals to meet the needs of multi-service applications, so we sometimes also It is called an integrated optical transceiver.
Our company has always focused on providing access layer network solutions and technical services for domestic and international telecom operators and industry private network customers, helping customers improve revenue, improve network operation efficiency, reduce operating costs, and achieve business success.

With the development of the network, network equipment such as switches, routers, and telephone optical transceivers have appeared successively. Today, we are talking about what fiber optic switches are.
What is the role of fiber optic switches? In data storage networks, fiber optic switches play an important role.
