Environmental Performance
Operating case temperature:
Operating humidity:
0°C to +70°C
0% -95% RH non-condensing
Fibers and Connectors
The transponder has SC receptacles for both Tx and Rx. The transponder is designed for
multimode SC cables, 0° polished endface (PC).
70-pin Connector
The module interface connector is a 70-pin, printed circuit board edge connection with a
0.5 mm pitch. The appropriate mating connector for the customer PCB is a 70-pin SMT,
dual row, right angled, edge connector, 0.5 mm pitch (Tyco Electronics part number
1367337-1, Molex part number 74441-0003 or equivalent).
Rail and Mechanical Mounting Requirements
The XENPAK rail system required to mount the XENPAK module is fully defined by the
MSA.
Aqueous Wash
Finisar XENPAK transponders are neither solderable nor aqueous washable and are not
intended for these processes.
