digital video optical transceiver

1 channel fiber optic video multiplexer 1 channel fiber optic video multiplexer
The 1 channel fiber optic video multiplexer accepts one composite video baseband signals via video BNC ports. It then performs a 10-bit linear analog-to-digital conversion on the baseband video signals, multiplexes the resulting PCM data, transmits the data optically via an optical fiber to the de-multiplexer.
2 channel fiber optic video transceiver 2 channel fiber optic video transceiver
The 2 channel fiber optic video transceiver accepts 2 composite video baseband signals via video BNC ports. It then performs a 10-bit linear analog-to-digital conversion on the baseband video signals, multiplexes the resulting PCM data, transmits the data optically via an optical fiber to the de-multiplexer(receiver).
4 channel fiber optic video transmission 4 channel fiber optic video transmission
The 4 channel fiber optic video transmission accepts 4 composite video baseband signals via video BNC ports. It then performs a 10-bit linear analog-to-digital conversion on the baseband video signals, multiplexes the resulting PCM data, transmits the data optically via an optical fiber to the de-multiplexer.
8 channel fiber optic video transmitter 8 channel fiber optic video transmitter
The 8 channel fiber optic video transmitter accepts 8 composite video baseband signals via video BNC ports. It then performs a 10-bit linear analog-to-digital conversion on the baseband video signals, multiplexes the resulting PCM data, transmits the data optically via an optical fiber to the de-multiplexer.

The 32 channel optical video transmission accepts 32 composite video baseband signals via video BNC ports. It then performs a 10-bit linear analog-to-digital conversion on the baseband video signals, multiplexes the resulting PCM data, transmits the data optically via an optical fiber to the de-multiplexer.
64 channel optical video transmitter 64 channel optical video transmitter
The 64 channel optical video transmitter accepts 64 composite video baseband signals via video BNC ports. It then performs a 10-bit linear analog-to-digital conversion on the baseband video signals, multiplexes the resulting PCM data, transmits the data optically via an optical fiber to the de-multiplexer.
In modern society, public security is of great importance to every nation, in many of the places such as airport, super markets, Schools, etc, people need to install a monitoring system to watch the places at real time. Our digital fiber optical video transmitters and receivers are used in such applications, by connecting to the cameras, the digital optical video transmitter can send the camera signal at real time via a single fiber, on the digital optical video receiver side, it will send the signal to computer screens and related devices, so that people can see what is being watched by the camera. With the Bi-directional data, people can send controlling data thought the digital optical fiber transceiver to control the moving of the camera, audio signals and Ethernet signals can also be sent via the single fiber line through the optical video transmitter and receiver.

Typical types of the digital optical video transmitter and receivers are mini type with one-way video signal, 2-channel type, and 4-channel type, 8 channel, 16 channels, and 32 channels, up to 64-channel type. For details please contact our sales team.

It is a significant breakthrough in the history of video optical transceiver development to digitalize the analog signal before transmission. Digital video transceivers solve many problems of the analog video optical transceivers, with the features of large data transmission volum, various types and better signal quality.
