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.
1.2 Feature
Comply with SMPTE-292M HD-SDI and SMPTE-259M SD-SDI standard, supports 1.485Gb/s and
