Chapter 1. Introduction
1.1 Overview
The L-4SDI-FE-HD-TX/RX is a high performance, and reliable, 4-channel HD-SDI video optical transceiver,
which perform real-time, loss-free and high-quality HD-SDI transmission（audio embedded) over an optical
line. Besides, L-4SDI-FE-HD-TX/RX provides one bi-directional RS485 data channel, and 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.
The L-4SDI-FE-HD-TX/RX includes a transmitter named L-4SDI-FE-HD-TX and a receiver named L-4SDI-
FE-HD-RX.
