Description
Overview
GAOTek optical multiplexer transmits 4 channels uni-directional 3G or HD-SDI signal over 1-core single model or multi-mode fiber, downward compatible with SD-SDI and ASI signal. Transmitter with loop out and receiver with dual output. It provides reliable high-quality transmission up to 100 KM (single mode fiber) and 0.5 KM (multi-mode fiber). Digital transmission meets the requirement of high-quality image transmission and can achieve the broadcast transmission level, full real-time transmission and non-time delay.
