3G-SDI Fiber Converter 4 Channel Tally RS485 20km Broadcast

Model : LNK-3GSDI-4V1DT Series

Product Description & Overview

The LNK-3GSDI-4V1DT Series represents a cutting-edge fiber optic transmission system engineered

for professional broadcast applications requiring multi-channel signal integrity. This advanced converter

extender simultaneously transmits four channels of uncompressed HD/3G-SDI video signals alongside

bidirectional RS485 data and tally control through a single fiber optic cable. Supporting full 1080p

resolution at broadcast-quality standards, this robust solution maintains pristine video quality with zero

compression or latency, making it ideal for mission-critical live production environments.

Featuring comprehensive loop-through output capability, this professional-grade system enables

seamless signal distribution while preserving original source quality across all four independent

channels. The integrated tally function provides real-time camera status indication, while the

bidirectional RS485 interface supports advanced camera control and equipment management.

Designed specifically for broadcast facilities, outside broadcast vans, and live event production,

this fiber-based solution eliminates electromagnetic interference and ground loop issues commonly

encountered in complex production setups.

The system's sophisticated optical engine ensures reliable transmission across extended distances while

maintaining perfect synchronization between all video channels and control signals. With hot-swappable

modules and automatic signal equalization, this converter establishes new benchmarks for multi-channel

broadcast transmission, providing exceptional value for sports broadcasting, studio production, and live

event coverage where signal reliability and operational flexibility are paramount. The rugged construction

and professional connectivity options make it an essential component in modern broadcast infrastructure

requiring simultaneous transmission of multiple high-definition video streams with integrated control

capabilities.
