TK-FO-VB08-M adopts digital video encoding and gigabit optical fiber transmission technology. The multi-channel single-direction bi-direction audio, video, data, telephone, Ethernet and switch real-time synchronization, no-distortion and high quality transmission is on the single-core or dual-core optical fiber. Complete digital video non-compression transmission technology, with video and data condition indicator, can monitor the system normal operation. It uses modular design, the user can flexibly select or customize configuration based on the scene occasion. Rack installation or desktop installation can be optional. This product is made up of optical transmitter and receiver. It can transmit simultaneously 8Channel bi-directional video, audio, data, phone, E1, Ethernet and switch.
