Environmental Performance Operating case temperature: Operating humidity: 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 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. 0C to +70C 0% -95% RH non-condensing
VI. Regulatory Compliance
Feature ESD: Electrostatic Discharge to the Electrical Pins (HBM) Immunity: Against Electrostatic Discharge (ESD) to the Module Receptacle Immunity: Against Radio Frequency Electromagnetic Field Emission: Electromagnetic Interference (EMI) Standard EIA/JESD22-A114-B (MIL-STD 883D Method 3015.7) EN 61000-4-2 IEC 61000-4-2 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.
