Description
Overview
GAOTek Optical Multiplexer is an audio optical transmission equipment that conforms to broadcast-level standards. It adopts advanced 24bit digital audio coding technology and can achieve a maximum of 64 channels of balanced audio single-fiber or dual-fiber long-distance transmission; Supports real-time synchronization and distortion-free transmission of one-way balanced audio signals and two-way balanced audio signals. Due to the use of digital optical fiber transmission technology, the transmission distance of audio signals is longer (up to 100 km), with strong anti-interference ability and larger transmission scale balanced audio optical transceiver is divided into single-channel, 2-channel, 4-channel, 8-channel, 16-channel, 32-channel, 64-channel and other models, one-way transmission and two-way transmission are optional. At the same time, it supports simultaneous transmission of user-customized unbalanced audio, high-definition video, control data, Ethernet, IO, IR, USB and other services.
