The ComNet™ FVT/FVR8018SHR series of optical video links provides eight 10-bit digital video channels, medium haul video quality, and 8 bi-directional data channels and a "Dual Optical Port" (DOP) Self-Healing Ring (SHR) topology. Up to eight video channels and multiple video receivers can be "Daisy Chained" on one optical fiber. The Self-Healing Ring (SHR) topology using the Dual Optical Ports (DOP) provide fail safe operation in the event of loss of one fiber or one optical module. Each optical port uses wavelength division multiplexing (WDM) to both transmit and receive on one optical fiber. The data channels support 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. Bi-color (Red/Green) LED indicators are provided for confirming operating status. Packaged in the exclusive ComNet ComFit housing, these units may be either wall or rack-mounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.
