4 Channel 3G-SDI Fiber Optic Converter with Gigabit Ethernet 20km Transmission

Model: LNK-3GSDI-4V1N Series

 Product Description & Overview

The 4-Channel 3G-SDI Fiber Converter with Ethernet represents a high-density fiber optic transmission

solution engineered for professional broadcast and live production environments. This advanced system

integrates four independent channels of 3G-SDI high-definition video signals alongside Gigabit Ethernet

connectivity through a single optical fiber strand. The complete setup includes matched transmitter and

receiver units that maintain pristine 1080p video quality with uncompressed broadcast-level transmission

standards, ensuring zero generation loss throughout the signal path.

Utilizing advanced wavelength division multiplexing technology, this converter efficiently consolidates

multiple signal types while providing integrated loop-through outputs for local monitoring at both transmission

and reception points. The integrated 1000M Ethernet channel enables simultaneous data transmission for

device control, network connectivity, and IP-based applications without compromising video performance.

The robust fiber optic architecture provides complete immunity to electromagnetic interference, ground loops,

and RF noise that commonly plague traditional copper-based video systems.

This high-performance converter finds ideal application in broadcast studios, live event production, sports

venues, and large-scale AV distribution systems where reliable multi-channel video transport is essential.

The single-fiber implementation significantly reduces infrastructure costs and simplifies cable management

while maintaining the stringent quality requirements of professional broadcasting. With its rugged construction

and broadcast-grade components, this solution offers television stations, production companies, and AV integrators

a reliable and scalable platform for distributing multiple high-definition video feeds between control rooms, across

campuses, or throughout large venues, establishing new standards for signal integrity in multi-channel video

transmission applications.
