In recent years, as analog cameras have been replaced by network cameras and high-definition coaxial cameras, at the optical fiber transmission layer, the previously used video optical transceivers have gradually been replaced by optical fiber transceivers, POE switches, network switches and other network optical communication equipment. At present, audio, data, switch, telephone, intercom and other signals on the market can still be transmitted through optical transceivers.

 

Video optical transceiver

 

Video optical transceivers are mainly used to transmit video and data (pan-tilt control) signals. In the early years, rental house video access control projects also used a large number of video + data + Ethernet optical transceivers.

Audio optical transceiver

 

Audio optical transceiver is mainly used for broadcasting and monitoring transmission layer. Through optical fiber, the transmission distance can be greatly extended without distortion of sound.

Ethernet optical transceiver

 

In the past few years, the use of video access control projects in safe cities and rental houses was very large. Video + Ethernet, video transmission analog cameras, and Ethernet transmission access control signals. In recent years, with the rise of the network digital high-definition market, this product is in Used less and less domestically
