Name: 4-channel digital video-audio / data/Ethernet video optical transceivers

Type:  FOWAY8004T/R series
Function: 4 channel bidirectional digital video broadcasting, 1~2 channel bidirectional high-fidelity audio, 1~4 channel bidirectional asynchronous data, 1 channel 10/100M adapt Ethernet data to one fiber efficiently.

Product information:
It is to transmit 4 channel bidirectional digital video broadcasting, 1~2 channel bidirectional high-fidelity audio, 1~4 channel bidirectional asynchronous data,1 channel 10/100M adapt Ethernet data to one fiber efficiently. With complete digital and technology, FOWAY8004T/R series support any high resolution dynamic or stationary picture high-fidelity transmits. It also can be anti-disturbance against several signals, environment, and work stably .It is widely used in security monitoring and control, high way, electronic police, automation, intelligent residential districts and so on.
It can work shortly after it is installed. You could select any data interface by set. It is connected easily and it can indicate power supply, link, and audio, also adjust video. There are two ways to install: desktop and rack.
