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 single  
mode 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 Requirement  
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.
