3G-SDI Fiber Converter HD-SDI 80km 1000M Optical Transmission

Model: LNK-HD-110 & LNK-3G-110 Series

 Product Description & Overview

The 3G/HD-SDI to Fiber Converter provides a reliable and high-performance solution for transmitting

professional broadcast video over long distances. This system is designed to support a single channel

of 3G-SDI or HD-SDI video with embedded audio, along with a reversed RS422/485 data channel for

control signals, all through a single optical fiber. The package includes a matched transmitter and

receiver pair, engineered to deliver pristine 1080P video quality while ensuring full compatibility with

SMPTE standards for uncompressed digital video transport.

With its advanced all-digital fiber optic transmission technology, this converter guarantees signal

integrity by eliminating electromagnetic interference, ground loops, and common issues associated

with traditional copper cabling. The integrated local loop-through output allows for immediate on-site

signal monitoring, enabling technicians to verify video quality and system status without disrupting

the main transmission path. This feature is particularly valuable in live production environments

where real-time verification is crucial for maintaining broadcast reliability.

This versatile converter is ideal for a wide range of professional applications, including broadcast

studio links, outside broadcast (OB) vehicles, sports venue production, and high-security surveillance

systems. Its robust design and plug-and-play operation make it equally suitable for permanent

installations and mobile setups. By converting electrical SDI signals to a robust optical format,

the system provides a future-proof foundation for expanding video networks, offering broadcasters,

integrators, and production teams a dependable method to extend signal reach without compromising

on the broadcast-quality performance required in today's demanding video landscape.
