1. Overview
1.1 Introduction
The 3U chassis series transceiver is designed using advanced ASIC and high-speed DSP
technologies. This series employs multiplexing techniques to transmit and receive 1-4
channel of Video, 1-2 channel simplex or bi-directional Data over a single-mode or
multi-mode optical fiber in all digital signaling with no compression; making it ideal for
applications where input signal integrity and quality must be maintained and no loss should
be induced. Because the series utilizes all-digital, non-compression technology, it is able to
transmit signals without distortion; whereas the analog technology inherently noisy, low
quality, long term instability and susceptible to electromagnetically and environmental
interference. This series accepts a variety of video inputs, such as analog or digital video
recorder, DVD/VCD, digital camera, and CCTV . PAL, NTSC and SECAM standards are
supported. It supports standard RS232/RS422/2 wires RS485 or 4 wires RS485 data
pan-tilt-zoom control signaling. Plug-and-Play design ensures ease of installation and no
electrical or optical adjustment is required. LED indicators are provided for showing
operating status.
The 3U chassis series is fully assembled using SMT components for stability and reliability.
