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 X2 rail system required to mount the X2 module is fully defined by the MSA.
(Tyco Electronics part number 1367608-1: designed for belly to belly applications;
and 1367610-1: designed for single sided board mount to fit into the standard host PCB
footprint, or equivalent). For further details, please refer to vendor-supplied information.
Aqueous Wash
Finisar X2 transponders are neither solderable nor aqueous washable and are not
intended for these processes.
