This module interfaces unframed serial optical to parallel copper. Fiber
optic I/O is at STM-1 (155.520 Mbps) or E4 (139.264 Mbps) rates and
parallel copper interface at ECL levels. Fiber optical interface
is through LC connectors, which are housed in a single mode, 1310
nm SFP device. Copper interface is made through 25 pin sub-mini D
connectors and BNC for CLOCK OUT.
Copper I/O consists of 8 DATA bits plus CLOCK and (3) additional
signals; TAPE SYNC, FRAME SYNC and ERROR. Front panel controls
and indicators include CLOCK OUT SELECT and RECORD and PLAYBACK
status indicators. SERIAL or PARALLEL mode and LED ON/OFF
are select by toggle switches located on the front panel.
Fiber optic I/O can be changed to multi mode and other wave
lengths, if desired.
The Optical DIR Interface Module is designed for use in the Technisys
Universal Modular Chassis (701073-XX).
