MIL-DTL-83522/16C
Fiber optic contact:
Method optical alignment: Sleeve/ferrule.
Lens configuration: Not applicable.
Coating requirements: Not applicable.
Nuclear radiation resistance: Not applicable.
Weight: 20 grams maximum.
Polarization: Key/slot.
Safety wire holes: Not required.
Force to engage and disengage:
Longitudinal force: Not applicable.
Torque: Not applicable.
Lubricants: Not applicable.
Water submersion: Not applicable.
Coupling proof torque: Not applicable.
Coupling mechanism retention force: Not applicable.
Tensile loading: The load shall be 230N minimum and shall not result in any physical damage. Optical
properties shall be monitored before and after load. The load shall not be applied to the coupling mechanism.
Optical transmittance measurements are not required during the test for the non-locking connectors.
Dust (fine sand): Applicable. Perform as specified in the requirements of MIL-DTL 83522 with the following
modifications:
a. The connectors shall not be rotated during steps 1 and 3. Each connector shall be oriented in the chamber
such that the key slot is in line with the oncoming air flow. The connectors shall be affixed in such a manner
that the orientation of the connector does not change throughout the duration of the test.
b. The change in optical transmittance shall be measured before the dust test, during the 6 hour exposure
period of step 1, before step 3, during the 6 hour exposure period of step 3, and after the test. Samples
shall be visually examined, after cleaning, at the conclusion of the dust test.
Ozone exposure: Not applicable.
High impact shock: Applicable to single mode and multimode locking and non-locking connectors.
Fluid immersion: Not applicable.
Residual magnetism: Not applicable.
Shock: For SM/MM connectors assemble on single mode fiber, signal discontinuity is applicable during shock
except that the duration for blows to the three axes are relaxed to a maximum of 1 second. For MM non-locking
connectors and SM/MM connectors assemble on multimode fiber, signal discontinuity is applicable during shock
except that the duration for blows to the side axis are relaxed to a maximum of 500 microseconds.
