Digital loss-less relayed transmission series
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.
