MIL-DTL-83526C
3.3.4.3 Solvents, adhesives and cleaning agents. No incompatability shall exist between the materials
employed in the fiber to terminus securing or polishing processes, such that degradation of these
materials shall result from in-service use or when tested in accordance with requirements of the
temperature life test of 4.9.20.
3.3.4.4 Epoxies. Epoxies are not precluded from use in the construction of the connectors controlled
by this specification. However, only those epoxy types, which have been tested and found to be fungus-
inert, shall be specifically defined in the detail specification sheet for the connector type. The detail sheet
shall also specify the process to be followed in mixing and curing the epoxy. Epoxies may not be used in
the optical path of the connector. The service life of epoxy material shall be consistent with the intended
useful lifetime of the connector. The termination and retermination of the connector shall not be affected
by the use of epoxy material.
3.3.4.5 Sealing compounds. Sealing compounds which may flow at the maximum upper storage
temperature specified herein, or crack at the minimum lower storage temperature specified herein shall
not be used.
3.3.4.6 Fungus resistance. All materials used in connectors designed to this specification shall be non-
nutrient to fungus. When tested in accordance with 4.11, connector materials shall show sparse or very
restricted microbial growth and reproduction with minor or inhibited substrate utilization. There shall be
little or no chemical, physical or structural change detectable.
3.4 Design and construction. Connectors, backshells and protective accessories shall be of the
design, construction, and physical dimensions specified (see 3.1).
3.4.1 Threads. Threads shall be in accordance with FED-STD-H28.
3.4.1.1 Thread lubricants. Suitable lubricants are allowed on ramps and threads of metal connectors.
Lubricants shall not be affected by cleaning solvents, which are required to maintain the optical
performance of the connectors.
3.4.2 Sealing. When specified, the connector design shall include environmental sealing capabilities at
the interface and rear of the connector. The seals, dynamic, static or both, shall preclude the entrance of
moisture, dust, sand, and dirt that might degrade the performance required under specified environmental
conditions.
3.4.2.1 Optical junction sealing. Optical junctions shall be sealed against moisture and contaminants
as specified herein.
3.4.2.2 Cable sealing. Connectors shall seal the terminating cables to meet the environmental
requirements specified herein.
3.4.2.3 Adhesives and sealing compounds. When specified, the connector manufacturer shall specify
necessary adhesives for terminating the optical fiber or for sealing the connector. These compounds
shall not be used unless otherwise specified (see 3.1).
3.4.3 Intermateability and interoperability (see Appendix A). When specified (see 3.1) connector parts
shall be intermateable and interoperable as specified in 3.4.3.1 and 3.4.3.2 respectively.
3.4.3.1 Intermateability. All connectors having the same termini, insert arrangement and shell size
shall be intermateable with their counterpart connectors (see Appendix A).
