Overview

VGA HD digital series of optical multiplexers adopt international advanced transmission technologies of digital uncompressed video and gigabit fiber, TDM, WDM, CWDM etc., transmitting various resolution VGA HD signals that output from 1-8 channel host computer, HD video signal source, 1-8 channel uni-bi-directional audio signals, 1-8 channel serial data(RS232/RS422/RW485), 100M network, on single/four fiber with real-time synchronization, no distortion, high fidelity. Broke through the limit of short-distance cable transmission for  VGA HD video signals, extended the application range and transmission distance, make it possible to widely spread HD video. VGA multiplexers support kinds of transmission formats like serial data RS232/RS422/RS485, contact closure, audio, Ethernet, phone etc. It’s modular design, 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.
