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.
