The Video Receiver/Data Transceiver with Self-Healing Ring from ComNet provides 10-bit digital video, 6.5 MHz bandwidth, medium haul video quality, one bi-directional data channel, and a Dual Optical Port (DOP) Self-Healing Ring (SHR) topology. Up to 8 video transmitters and multiple video receivers can be daisy-chained on one optical fiber. The Self-Healing Ring (SHR) topology, using the Dual Optical Ports (DOP), provides 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 channel supports RS232, RS422, and 2 wires and 4 wires 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 ComFit housing, this unit can be either wall or rack-mounted, or may be DIN-rail mounted by use of the DINBKT1 adapter plate.
