VT/VR7200 Series
IFS 2-Channel Digital
Video Multiplexer
Overview
The IFS VT/VR7200 series multiplexers simultaneously
transmit two channels of video over one optical fiber
utilizing 8-bit digital encoding for high-quality video
transmission. These products exceed EIA RS-250C
for Medium-Haul Video Transmission performance
requirement. The modules are universally compatible
with major CCTV camera manufacturers. Plug-and-play
design ensures ease of installation requiring no electrical
or optical adjustments. The modules incorporate Power,
Receiver Locked and Video Presence Status indicating
LED’s to monitor proper system operation. The modules are
available in either stand-alone or rack mount versions.
