1U Rack-Mountable 8-Channel SD/HD/3G-SDI over Single Fiber CWDM Uncompressed Extender
Overview
LNK-SDI-8V Series is a high-performance 8-channel SD/HD/3G-SDI fiber optic transmission system,
capable of transmitting broadcast-quality video and CD-level audio over a single fiber cable. Each
unit includes a transmitter and receiver, supporting 1080P 3G-SDI signals with a local loop output
for real-time monitoring.
Key features include:
- 8-channel SD/HD/3G-SDI video transmission
- 1-channel reverse RS-485 data communication
- Single-fiber solution for efficient cabling
- High-quality video (up to 3G-SDI) and CD-grade audio
Ideal for broadcast, live production, and professional AV systems, this converter ensures reliable,
long-distance signal transmission with minimal latency.
