Mini 3G-SDI Fiber Converter with Tally RS485 80km CWDM Option

Product Specification

Model: LNK-M3G-1V Series

 Product Description & Overview

The Mini-type 3G-SDI to Fiber Converter with Tally & Reverse RS485 provides a comprehensive yet

compact solution for professional video transmission. This system supports a single channel of high-

definition 3G/HD-SDI video with embedded audio, along with integrated tally signaling and reverse

RS485 control data, all transmitted over a single optical fiber. Designed for complete signal transparency,

it includes a matched transmitter and receiver pair, delivering pristine 1080P resolution with a local loop-

through output for real-time monitoring at the transmission point.

Engineered for operational flexibility, this miniature converter integrates critical production signals into

one streamlined fiber link. The tally channel ensures clear visual communication between the control

room and camera operators, while the bidirectional RS485 interface enables reliable remote control

of PTZ cameras, lenses, and other studio equipment. Its compact form factor makes it an ideal choice

for space-constrained installations, such as broadcast flypacks, camera backplates, and mobile

production units, without sacrificing performance or features.

This robust converter is built to meet the demanding requirements of live production and broadcast

environments. It is perfectly suited for applications such as live event broadcasting, electronic news

gathering (ENG), studio camera links, and high-end video conferencing systems. By converting

electrical signals to optical format, the system provides complete immunity to electromagnetic

interference and ground loop issues, ensuring a stable and reliable connection. This solution

offers broadcasters and AV professionals a powerful, all-in-one tool for extending and managing

professional video signals with maximum reliability and minimum footprint.
