How are optical terminals classified? What are the classifications of optical terminals?

Optical transceiver has different classification methods based on different classification methods. If classified from the interface of optical transceiver, it can be roughly divided into video optical transceiver, audio optical transceiver, telephone optical transceiver, digital optical transceiver, and Ethernet optical transceiver. Below, the editor will briefly introduce it to everyone!
Video optical transceiver:
Video optical transceiver is a device that converts one to multiple analog video signals into optical signals through various encodings and transmits them through fiber optic media. As the process of converting video signals into optical signals involves two technologies: analog conversion and digital conversion, video optical transceiver is further divided into analog optical transceiver and digital optical transceiver. The principle of optical transceiver is to modulate signals onto light and transmit video through optical fibers.
Audio optical transceiver:
Audio optical transceiver is an audio device that converts traditional audio analog signals into optical signals at the transmitting end, transmits them to the receiving end through optical fibers, and then converts them into analog signals at the receiving end.
Telephone optical transceiver:
A telephone optical transceiver is a device that converts traditional telephone signals into optical signals and transmits them over optical fibers.
Digital optical transceiver:
Digital optical transceiver is a machine that controls optical signals through digital circuits and uses codes similar to 0 and 1 to achieve optical communication. It is widely used in fields such as fiber optic communication.
Ethernet optical transceiver:
Ethernet optical transceiver is a 10/100Mbps intelligent adaptive fast Ethernet optoelectronic converter that can transmit data between two different network transmission media, twisted pair and fiber optic.
