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