Description
Overview
GAOTek 24 channel Fibre optic video multiplexer is a full-featured all-digital video optical transmission equipment that can transmit 24-Channel high-quality (8 Bit/10 Bit) uncompressed video information and 1-Channel reverse data on one fibre at the same time, optional audio, data, switch volume. This product is convenient for field wiring, no need for any photoelectric adjustment; with power, optical and data loop instructions; optional two structural forms: standalone desktop installation and modular rack mounted. This series digital optical products are mainly used for long-distance optical fibre transmission monitoring systems, such as security monitoring, highways, electronic police, automation, intelligent community, customs, electricity, water, petroleum, chemical and many other fields.
