12G-SDI to Fiber Converter with Gigabit Ethernet and 2Ch Backward RS485
Model: LNK-12GSDI-1V2R1GE Series
Overview
The LNK-12GSDI-1V2R1GE Series is a high-performance 12G-SDI to Fiber Converter with
Gigabit Ethernet and 2Ch Backward RS485, specifically engineered to enable synchronized
transmission of multi-signal types over a single fiber optical cable—combining robust video
performance with flexible data and network connectivity. As a 12G-SDI to Fiber Converter with
Gigabit Ethernet and 2Ch Backward RS485, it is designed for professional broadcast, surveillance,
and industrial video applications where ultra-high-definition (UHD) video, reliable data communication,
and network access are critical.
This converter supports transmission of 1Ch 12G-SDI video signals (with embedded audio for
seamless audio-video synchronization),1Ch Gigabit Ethernet signals, and 2Ch Backward RS485
data signals via a single fiber optical cable, eliminating the need for multiple cables and simplifying
infrastructure deployment. It features a local 12G-SDI loop output, allowing users to monitor the source
video signal in real time at the transmitter end—ensuring signal integrity before transmission and facilitating
quick troubleshooting in professional setups.
The 12G-SDI to Fiber Converter with Gigabit Ethernet and 2Ch Backward RS485 comes as a complete
set, including one transmitter unit and one receiver unit, to form a full transmission link. It supports a wide
range of video resolutions and formats, covering HDTV 4K2K (38402160@60Hz) for UHD applications,
as well as lower resolutions such as 1080P, 1080I, and 720P—ensuring backward compatibility with
existing SD/HD/3G-SDI systems and flexible adaptation to diverse project requirements. The embedded
audio function maintains CD-level audio quality, while the 1Ch Gigabit Ethernet port enables high-speed
data transfer for networked devices (such as IP cameras, NVRs, or remote control systems), and the 2Ch
Backward RS485 supports bidirectional serial data communication for remote device control, such as PTZ
cameras or industrial controllers.
With its stable signal transmission, broad format compatibility, and integrated multi-signal capabilities, this
converter is ideal for professional scenarios including broadcast studios, large-scale UHD surveillance networks,
live event video transmission, remote industrial monitoring, and high-end digital signage systems. It effectively
resists electromagnetic interference (EMI) and signal attenuation over long distances, ensuring consistent UHD
video quality and reliable data communication—making it a comprehensive and cost-effective solution for modern
professional video transmission needs.
