Product Description

The ComNet FVT/FVR40A4 series video/audio multiplexer utilizes 10-bit video encoding for true EIA/TIA RS-250C Short-Haul broadcast quality transmission, and 24-bit encoding at a 96 Khz sampling rate for the highest possible audio fidelity. Digitally Encoded transmission ensures that the video and audio performance remain completely unaffected up to the maximum usable optical transmission distance or optical path loss. These environmentally hardened units provide the transmission of four independent simplex video and four independent simplex line-level audio channels over one multimode or single mode optical fiber. The FVT/FVR40A4 series is completely transparent to and universally compatible with any NTSC, PAL, or SECAM camera system. Plug-and-play design ensures ease of installation, and no electrical or optical adjustments are ever required. Bi-color (red/green) LED indicators confirm equipment operating status. Packaged in the exclusive ComNet ComFit housing, these units may be either shelf or rack-mounted, or may be DIN-rail mounted by the addition of the ComNet model DINBKT1 adaptor plate.
