1, 2 OR 41, 2 OR 4INCLUDED

The ComNet™ series video transmitters and receivers support the transmission of
one, two, or four independent short-haul quality 10-bit digital video signals and one,
two, or four contact closures in the direction of the video over multimode or single
mode optical fibers. This module is universally compatible with major CCTV camera
manufacturers. The receivers are compatible with the FVT10C1(M,S)1[/M] series or
FVT1(M,S)1/M* single channel transmitters. Plug-and-play design ensures ease of
installation and no electrical or optical adjustments are ever required.
