8-Ch 3G-SDI + 10G Ethernet Fiber Extender Broadcast-Grade Transmission
Overview
The LNK-3G8V10GE is a professional-grade fiber extender that integrates 8 channels of 3G-SDI/ASI
video with embedded audio and one 10G Ethernet link over a single optical fiber. Designed for
broadcasting, surveillance, and live production, it delivers real-time uncompressed HD video and
high-speed data with excellent stability. With built-in CWDM technology, automatic cable equalization,
and long-distance optical transmission up to 20km (optional 40/60/80km), this solution ensures
unmatched reliability in demanding environments.
