12G-SDI Fiber Converter 4K@60Hz Gigabit Ethernet 80km Dual RS485 Control

12G-SDI to Fiber Converter with Gigabit Ethernet and 2Ch Backward RS485

SDI Fiber Extender Overview

The LNK-12GSDI-1V2R1GE Series represents a cutting-edge fiber optic transmission solution engineered for ultra-high-definition broadcast and production environments. This advanced converter seamlessly transmits one channel of 12G-SDI video with embedded audio, Gigabit Ethernet data, and two channels of bidirectional RS485 control signals through a single fiber optic cable.

Utilizing sophisticated optical technology, the system delivers exceptional 4K UHD video quality at 3840×2160@60Hz resolution while maintaining full compatibility with legacy HDTV standards including 1080P, 1080i, and 720P formats. The integrated local loop-through output enables real-time signal monitoring and verification without interrupting the primary transmission path, ensuring continuous operation reliability.

Specifically designed for next-generation broadcast infrastructure, this converter provides complete electrical isolation and immunity to electromagnetic interference, guaranteeing signal integrity in demanding production environments. The robust architecture supports mission-critical applications where uncompromised video quality and reliable data transmission are paramount.

Ideal for 4K studio productions, live event broadcasting, and high-resolution medical imaging systems, this comprehensive solution establishes new benchmarks for signal fidelity and system integration. The dual RS485 channels facilitate sophisticated device control and automation, while the Gigabit Ethernet interface enables seamless IP network integration for modern broadcast workflows and remote production requirements.
