Test samples (termini on single fiber cable) shall be tested to TIA/EIA-455-16, test condition C. Terminus ferrule may be covered up to half way from the end face to the shoulder with plastic protective (dust) covers. No corrosive effects shall be seen on the external connector parts that would be detrimental to the operation of the connector. No optical degradation shall occur as a result of this test. The criterion for insertion loss verification shall be used to determine if this optical requirement is met. Insertion loss verification, with termini inserted into a MIL-DTL-38999 shell size 17; series III connector, shall be performed both prior to and after the salt spray test. Inspections for termini as an integral part of a multiple termini connector: Test sample configuration: Four test samples (mated connector assemblies) shall be used for group I inspections except for interoperability. Two of these four mated connector assemblies shall be used for group II inspections and two for group III inspections. Each mated connector assembly shall be comprised of a cable assembly with termini placed into MIL-DTL-38999 shell size 17, series III connectors. These termini/connectors are located in the middle of the cable assembly. Termini, selected from the group that passed inspections for un-terminated termini, shall be used and inserted into MIL-DTL-38999 shell size 17 or higher, series III connectors as part of the cable assembly that comprises each test sample. Cable assembly length shall be 10 meters with the connector mated pair inserted 5 meters from the cable ends. Cable length may be longer (with added cable at the optical source end) if cut-backs are performed to verify insertion loss. Each connector shall be fully populated with termini. At least 8 randomly selected termini pairs in each cable assembly shall be monitored for optical transmittance after and when specified, during environmental and mechanical testing. Insertion loss shall be performed on all termini pairs in each cable assembly. Connectors used in the cable assembly, both the plug and receptacle types, are to include backshells. Selection of the backshell is to include assurance of proper strain relief for each single fiber cable and not cause degradation in optical performance. Test sample configurations, fabrication methods and the specific test methods and practices shall be as specified in NAVSEA Drawing 8283255. Interoperability. Applicable, except test for terminus insertion and removal forces is not required. Testing shall be performed using two separately designated cable assemblies with fully populated, MIL-DTL-38999, series III, shell size 17 connectors. Test performance and test sample configurations/fabrication shall conform to NAVSEA Drawing 8283255. As part of the interoperability inspection, terminus on the end of single fiber cable, shall be inserted and removed from the connector to verify that the strain relief is compatible with the tools listed in table II. At the discretion of the preparing activity, selected configurations may be specified to undergo inspections for shock, vibration, and mating durability. Interoperability is applicable only for termini among vendors with the same TICC such as fiber size, ferrule hole diameter, and ferrule material (see table I) with one addition. Termini shall be interoperable regardless of the style. Qualification by similarity will be given to a terminus in the same row in table I as the terminus tested for interoperability. This qualification by similarity is valid if the only difference between the terminus tested for interoperability and the terminus configuration in the same row in table I is a different cable strain relief capture mechanism and TICC markings. Optical source wavelength. Termini with single mode fiber shall be tested using an optical source at the 1,310 nm wavelength. Termini with multimode fiber can be tested using an optical source at either the 850 nm or the 1,300 nm wavelength. - - ` ` , ` ` ` , ` , , , , ` ` , , ` , ` , , , , , , ` , - ` - ` , , ` , , ` , ` , , ` - - - MIL-PRF-29504/5D w/AMENDMENT 1 9 Launch conditions shall conform to NAVSEA Drawing 8283255: Insertion loss.
