HF002-Node Transmission
10-channel node digital video transmission series of optical multiplexers adopt way of uncompressed digital
video transmission, combined TDM and ADM technologies; 10 node cascading multiplexers use 1.25G optical transmission platform, simultaneously transmitting 10-channel video signals, 10-channel uni/bi-directional data/audio signals, and supporting max 10 node, remote side can access 1-4 channel video signals, 1-channel bidirectional audio/data, 1-channel 485 data; local side can output 10-channel video/data/audio signals and 1-channel 485 data in real time. Designed in wide operating temperature from -30 ºC to 75 ºC with performance of dust/salt fog proof, makes it completely suitable for harsh environments.
