Direct 9 Optical Transceiver

Direct Optical Transceiver

Moog Protokraft Direct 9 series D-Subminiature optical fiber transceivers consist of optoelectronic transmitter and receiver functions integrated into a printed circuit board mounted D-Sub connector utiliing ARINC 801 termini. The electrical interface to the Direct 9 series D-Sub optical transceiver is a solder PIN field with the same PCB footprint as existing electrical 9 position D-Sub connectors.

The optical interface to the Direct 9 series optical transceivers is a DB-9 connector with ARINC 801 termini enabling interconnection to optical fiber cable assemblies. The multimode optical fiber interface supports applications where copper cable link distance, bandwidth, weight or bulk make the use of twisted pair, twinax or quadrax copper conductors unacceptable.
