Network & Communication

The ComNet™ FVT/FVR107 series of optical video links provides 10-bit digital video, 10 Mhz bandwidth, short haul video quality, one bi-directional data channel and a dual optical port redundant Point-to-Point topology plus eight contact closures and two alarm relays. The redundant Point-to-Point topology using the dual optical ports provide fail safe operation in the event of loss of one fiber. Each optical port uses wavelength division multiplexing (WDM) to both transmit and receive on one optical fiber. Microprocessor-based logic sends the contact information in packets that are ordered and encoded, ensuring extremely robust transmission. Packets that are garbled, packets out of sequence, and transmission bit errors will not cause random changes of state on the contact relays. Also, the mechanical latching relays maintain their state even when the unit loses power. The data channel supports RS232, RS422 and 2 wire and 4 wire RS485. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.

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.

The ComNet™ FVT/FVR10D1A2C1 video transmitter/data transceiver and video receiver/data transceiver series utilize 10-bit digital encoding and decoding for highquality video transmission that meets the requirements of EIA RS-250C for short-haul video transmission. These environmentally hardened units provide transmission of one independent video channel and one bi-directional data channel over one optical fiber and are ideal for use in unconditioned roadside or out-of-plant installations. They also provide transmission of two bi-directional audio signals and one bi-directional contact closure over the same fiber. The modules use 24-bit 96kHz sample rate digital encoding for superior transmission of balanced line-level audio. It also supports "up-the-coax" data transmission from all major manufacturers. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.
