Chapter 1. Introduction
1.1 Overview
The L-2SDI-FE-HD-TX/RX is a high performance, and reliable, 2-channel HD-SDI video optical
transceiver, which perform real-time, loss-free and high-quality video transmission and one unidirectional
(default)/bi-directional RS485 data over an optical line. Besides, L-2SDI-FE-HD-TX/RX provides optional
audio/contact closure/RS422/RS232 data transmission, which can be widely used in TV live broadcast,
high-definition video conference, high-definition video monitoring, intelligent transportation system and
public security system.Fiber optical transmission excludes electromagnetic noise factor, it makes this
product a perfect solution for efficient, reliable and secured SD/HD-SDI signal transport.

Note1: The AUX interface of L-2SDI-FE-HD-TX and L-2SDI-FE-HD-RX are used in pairs, e.g. if L-2SDI-FE-
HD-TX use 2-channel unidirectional audio output interface, L-2SDI-FE-HD-RX should use 2-channel
unidirectional audio input interface.
Note2: If the auxiliary channel is used as the audio channel, the embedded audio channel in the HD-SDI
signal will be unavailable.
