1. Overview
HC***2M adopts the latest optical communication technology,
and makes *-channel positive-going video, *-channel
bidirectional audio, *-channel sync switch, and *-channel Ethernet
multiplexed over a fiber transmission; video signal
compatible with PAL, NTSC and SECAM formats. Easy
installation, without any adjustment to the work; could transmit
signals of video, audio, data and Ethernet up to **0km above. Now
it is widely used in radio and television transmission, video
surveillance, railway/highway monitoring, security, video
conferencing and other fields.
