We all know that telephone optical transceiver is a device that converts traditional telephone signals into optical signals and transmits them on optical fibers. However, as for the classification of telephone optical transceivers, you may not understand very clearly. Telephone optical transceivers have different classification methods according to different classification methods. Today, the editor of Feichang Technology mainly introduces to you, according to the application field. Division, what are the main types of telephone optical transceivers? Let's take a look together next!
1. Surveillance telephone optical transceiver:
used to transmit video signals (for example, the output of ordinary cameras is video signals), and can also assist in the transmission of audio, control data, switch signals and Ethernet signals. It is mainly used in highways, urban traffic, Community security and various areas that need to be monitored;
2. Telephone optical transceiver
for radio and television: used to transmit radio frequency signals. Its terminal is not point-to-point transmission. It branches directly in the optical path, and can be used from one transmitter to multiple receivers. It is mainly used in the optical transmission field of cable TV;
3. Telephone optical transceiver for telecommunications:
each basic channel of its terminal is 2M, also commonly known as 2M terminal. Each 2M channel can transmit 30 telephones or transmit network signals with 2M bandwidth. It is just a fixed-band four-channel telephone optical transceiver. The use of the channel mainly depends on the supporting equipment connected to the optical transceiver. The supported protocol is the G.703 protocol, which is mainly used in the field of fixed-bandwidth telecom optical communication.
4. Telephone optical transceivers for electric power:
Based on different applications in these fields, the telephone optical transceivers used by radio, television and telecommunications are relatively fixed and have fewer varieties.
Well, the above is the related introduction of the classification of telephone optical transceivers according to the application field compiled by the editor of Feichang Technology for you. I hope it can be helpful to you.
