4 Channel 3G-SDI Fiber Converter with RS485 Tally 20km Broadcast
Model: LNK-3GSDI-4V1DT Series
Product Description & Overview
The 4-Channel 3G-SDI Fiber Converter with RS485 & Tally delivers a high-density, integrated solution
for professional broadcast signal transmission. This advanced system consolidates four independent
channels of 3G-SDI high-definition video, four tally signaling channels, and a bi-directional RS485 data
path onto a single optical fiber. The matched transmitter and receiver pair is engineered to maintain
pristine 1080p video quality using non-compressed, broadcast-level transmission technology, ensuring
zero generation loss for the most demanding production environments.
Utilizing sophisticated fiber optic multiplexing technology, this converter significantly simplifies infrastructure
by reducing cable complexity while providing each video channel with a dedicated loop-through output for
local monitoring. The integrated RS485 interface enables reliable remote control of cameras, robotic
systems, and other studio equipment, while the multi-channel tally system ensures clear visual communication
between the control room and camera operators. This comprehensive signal integration makes the system
ideal for live broadcasts, sports production, and studio applications where space, reliability, and signal clarity
are paramount.
Designed specifically for the broadcast industry, this robust converter is widely used in outside broadcast
(OB) vehicles, production control rooms, and studio-to-transmitter links. Its ability to handle multiple video
feeds alongside critical control and communication signals over a single fiber makes it a cornerstone for
modern, efficient broadcast facilities. By providing immunity to electromagnetic interference and signal
degradation, this solution offers broadcasters a reliable and future-proof method for expanding their
production capabilities while maintaining the highest standards of video quality and operational control.
