ComNet FVT107M1 Video Extender Transmitter

ComNet FVT107M1 Video Extender Transmitter

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.

• Designed for installation in harsh out-of-plant/unconditioned industrial or roadside operating environments (-40 to +75C ambient). Fully compliant with the environmental requirements of NEMA TS-2 for Traffic Signal Control Equipment


• Compatible with all NTSC, PAL, or SECAM CCTV camera systems


• Exceeds all requirements for RS-250C short-haul video transmission: True broadcast video performance


• Dual optical port Redundant Point-to-Point (RPP) configuration


• Two separate alarm relay outputs indicate when a fiber link is lost and which optical port.


• Microprocessor-based logic and latching relays in receiver unit eliminate random contact closure status in the event of loss of link or loss of prime operating power.


• Eight SPST latching relays (with individual LED indicators)


• Distances up to 30 miles (48 km)


• 10-bit digital video transmission


• Bi-directional data channel supports RS232, RS422 or RS485 (2 or 4-wire) interfaces.
