8Ch SD/HD/3G-SDI Fiber Converter with Loop-out 20km Transmission
Rackmount
Overview
This 8-channel SD/HD/3G-SDI fiber converter enables high-quality,
uncompressed video
transmission over a single-mode fiber for distances up to 20km.
Designed for broadcast,
security, and professional video applications, it supports various
SDI formats including
1080P 3G-SDI, with loop-out monitoring and optional reverse RS-485
data or forward audio.
The 1U rackmount design, robust aluminum casing, and wide
temperature range ensure
reliable operation in demanding environments.
