The 10-Bit Digital Single-Mode Video Receiver/Data Transceiver from ComNet provides 10-bit digital video, 10 MHz bandwidth, and short-haul video quality, one bi-directional data channel, and a dual optical port redundant Point-to-Point topology. It also features 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, or RS485 (2- or 4-wire) interfaces. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.
