907 Multiplexer

FIBER OPTIC MULTIPLEXERS

The 907 video / data multiplexer provides digital transmission over 1 or 2 singlemode or multimode optical fibers for 3 high quality video channels and 6 bidirectional data channels (4 x RS-232 and 2 x RS-485 / 422 / TTL) in a single, compact PC / 104 form factor card.

Expansion cards may be added to convert data channels on the motherboard to other data formats, such as Ethernet, analog sonar, hydrophone and Tritech ARCNET, or to replace each motherboard channel with up to 8 lower data rate serial channels. Optical power budgets are typical 20-26 dB with 2-4 km of multimode fiber or 10 km of singlemode fiber. LEDs provide on-board diagnostics for data, video and optical link status.

Features
