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 and Mechanical Mounting Requirements
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.

Comments
Class 1a (> 500 V)
Discharges ranging from ±2 kV to ±25 kV to
the front end / faceplate / receptacle cause no
damage to module (under recommended
conditions).
With a field strength of 10 V/m, noise
frequency ranges from 10 MHz to 2 GHz. No
effect on module performance between the
specification limits.
Noise frequency range:
30 MHz to 40 GHz
Radiated emission does not exceed specified
limits when measured with module inside a
shielding enclosure with a MSA conforming
cutout.
