special function seriesMini digital video seriesdescription
Mini digital video optical multiplexers are now the smallest multiplexers at Home, adopting advanced
technology, small size, high performance, especially suitable for sites with special requirements for installation size, volume, space etc. It can be built into dome camera or shield, 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.Mini digital video optical multiplexers transmit 1-channel video/data (RS-232/422/485 Manchester code optional) on single fiber with no distortion, high quality. Overcoming the fatal weaknesses of serious cross interference when multi-channel signals of the regular simulating FM, phase, amplitude multiplexer transmitting simultaneously, environment disturbance, poor transmission quality, long-term low working stability. It has been widely used in many fields such as security monitoring, expressway, electronic police, automation, intelligent districts, customs, electricity, petroleum, chemical industries, coal mines etc.
Digital loss-less relayed transmission seriesDigital loss-less relayed transmission seriesdescription
Digital loss-less relayed transmission multiplexers adopt international advanced technologies of digital
uncompressed video/audio/data multiplexing, and fiber communication WDM/CWDM/TDM, extending general uncompressed video signals to long distance without limits, the circuit signals realized multiplexing in digital domain and reached true loss-less uncompressed transmission of video signals.
Digital loss-less relayed transmission multiplexers transmitted to 80km, loss-less transmission signals. Simple structure is different with usual main amplifying and AGC control circuit of optical receiver, adopting improved optical receiver modules and developing a new waveform equalization circuit, to make sensitivity and dynamic range reach higher practical level. Double-end laser driver circuit combining damping with compensation to reach the purpose of long-term transmission and make video signals to be of high-quality transmission with high fidelity, no distortion.
Dual fiber self-healing ring transmissionDual fiber self-healing ring transmissiondescription
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.
