Dual fiber self-healing ring transmission
Dual fiber self-healing ring optical multiplexers adopt way of 1+1 dual fiber ring to realize uncompressed digital
video transmission, simultaneously transmitting max 128-channel video/data/audio signals (uni/bi-directional) by dual fiber; remote side can access max 1-16 channel video, bidirectional data/audio signals, 1-channel 485 control data; local side can output max 128-channel video/data/audio signals in real time. The video quality can reach broadcasting standard, support data communication like RS-232, RS-422 and RS-485(2/4 wire) etc., support audio format like unidirectional surveillance, intercom etc. It’s plug and play, no needing field regulation, 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.
