Overview

HD-SDI digital series of optical multiplexers adopt international advanced transmission technologies of digital uncompressed video and gigabit fiber, TDM, WDM, CWDM etc., transmitting 1-8 channel HD-SDI video signals, 1-8 channel uni/bidirectional audio signals, 1-8 channel serial data(RS232/RS422/RW485), 100M network, on single fiber with real-time synchronization, no distortion, high fidelity. 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.
