12G-SDI Fiber Converter with Gigabit Ethernet 2Ch RS485 80km 4K Transmission
Model: LNK-12GSDI-1V2R1GE Series
Product Description & Overview
The 12G-SDI to Fiber Converter with Gigabit Ethernet and 2Ch Backward RS485 represents a cutting-edge
solution for ultra-high-definition video transmission in professional broadcast and production environments.
This advanced fiber optic system supports single-channel 12G-SDI video transmission with embedded audio,
complemented by Gigabit Ethernet connectivity and dual-channel bidirectional RS485 data communication
through single-mode fiber infrastructure. The integrated 12G-SDI loop output enables real-time local monitoring
while maintaining signal integrity throughout the transmission path.
Engineered to meet the demanding requirements of 4K production, this converter pair delivers exceptional
video quality supporting resolutions up to 3840×2160@60Hz while maintaining backward compatibility with
1080P, 1080I, and 720P formats. The system employs advanced fiber optic technology to ensure complete
immunity to electromagnetic interference, ground loops, and signal degradation, providing reliable performance
in electrically noisy environments. The dual RS485 channels facilitate comprehensive remote device control for
cameras, PTZ systems, and other broadcast equipment requiring bidirectional communication.
This high-performance converter finds ideal application in 4K broadcast studios, live event production, sports
broadcasting, and high-resolution surveillance systems where uncompromised video quality and reliable data
transmission are essential. The integrated Gigabit Ethernet channel supports network connectivity for device
management, IP video streaming, and data transfer, while the fiber optic transmission ensures secure, interference-
free operation over extended distances. By consolidating multiple signal types through a single fiber connection,
this solution significantly reduces infrastructure complexity while providing the bandwidth necessary for next-
generation video production, establishing new standards for ultra-high-definition signal transmission in
professional broadcast applications.
