The ComNet FVR1C1B receives one channel of video over one optical fiber utilizing 8-Bit digital decoding for high-quality video and contact closure transmission. These environmentally hardened units are ideal for use in unconditioned roadside or out-of-plant installations. This module is universally compatible with major CCTV camera manufacturers. Features Wide optical dynamic range: optical attenuators are never required NTCIP compatible Robust design ensures extremely high reliability in unconditioned out-of-plant environments Status indicating LEDs provide rapid indication of critical operating parameters. Automatic resettable solid-state current limiters Lifetime Warranty Contact closure Exceptionally low video distortion with zero Performance Variation vs. Optical Path Loss Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events. ComFit standard form factor is interchangeable between stand-alone or rack mount use. Compatible with NTSC, PAL, or SECAM Video Standards 8-bit digitally encoded video exceeds all requirements for EIA RS-250C medium-haul transmission. Tested and certified by an independent laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/ TS-2 and the Caltrans Specification for Traffic Signal Control Equipment. Standard ComFit models are hot-swappable.
