This digital video optical transceiver 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 48Channel forward direction Video and 1Channel reverse direction RS485 data.
◆ Complete digital optical fiber transmission platform, same platform multi-service flexible configuration;
◆ Provide General desktop, Mini desktop, insert-card Rack;
◆ Based on self –copyright ASIC;
◆ Can detect the remote device that is power off or broken fiber when it is matt
◆ Compatible PAL/NTSC/SECAM system, studio-level transmission quality
◆ Provide bi-directional asynchronous data (Forward Direction and Reverse Direction)
◆ Asynchronous data, transmit rate more than 110-115.200Kbps
