Mini 12G-SDI Fiber Converter with Tally RS485 80km 4K Transmission

Model: LNK-M12G-1V1T1D Series

 Product Description & Overview

The Mini 12G-SDI to Fiber Converter with Tally and RS485 represents a compact yet powerful solution

for high-performance 4K video transmission in space-constrained broadcast environments. This

miniaturized fiber optic system integrates single-channel 12G-SDI video with embedded audio, tally

signaling, and bidirectional RS485 data communication through a streamlined fiber infrastructure.

The integrated 12G-SDI loop output provides real-time local monitoring while maintaining pristine

signal quality throughout the transmission chain, ensuring reliable performance in mission-critical

applications.

Engineered for ultra-high-definition production requirements, this compact converter pair delivers

exceptional video quality supporting 4K×2K resolution at 3840×2160@60Hz while maintaining full

backward compatibility with 1080P, 1080I, and 720P formats. The miniature form factor belies its

robust capabilities, incorporating advanced fiber optic technology that provides complete immunity

to electromagnetic interference and ground loop issues. The integrated tally channel enables precise

camera status indication, while the RS485 interface facilitates comprehensive remote control of

cameras, lenses, and other broadcast equipment.

This space-efficient converter is particularly suited for broadcast flypacks, mobile production units,

and compact studio installations where rack space is at a premium. The miniature design enables

flexible deployment in crowded equipment racks, camera mounts, and portable production setups

without compromising on performance. The fiber optic transmission ensures secure, interference-

free operation over extended distances, making it ideal for 4K outside broadcasts, electronic news

gathering, and high-resolution live production applications. By consolidating essential broadcast

signals in a compact footprint, this solution provides broadcasters and production teams with a

reliable, high-performance transmission option that meets the demanding requirements of modern

ultra-high-definition production while optimizing space utilization in increasingly crowded equipment

environments.
