MIL-PRF-24623C
3.3.5 Solvents, adhesives and cleaning agents. If epoxy or comparable cement is
used in the splicing processes, no incompatibility shall exist between the materials
employed such that degradation of the materials can result from in-service use or when
tested in accordance with the requirements of the life aging test of 3.7.2.
3.3.6 Nonmetallic materials. Nonmetallic materials used in the construction of
splices shall not be affected by the use of solvents, adhesives, or cleaning agents,
nor be degraded at the specified environmental conditions.
Liquid materials shall not be used.
3.3.7
Liquid materials.
3.3.8 Fungus resistance. When tested in accordance with 4.7.2.14, polymeric splice
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.
3.3.9 Recovered materials. Unless otherwise specified herein, all equipment,
material, and articles incorporated in the products covered by this specification
shall be new and shall be fabricated using materials produced from recovered materials
to the maximum extent practicable without jeopardizing the intended use. The term
"recovered materials" means materials that have been collected or recovered from solid
waste and reprocessed to become a source of raw materials, as opposed to virgin raw
materials. None of the above shall be interpreted to mean that the use of used or
rebuilt products is allowed under this specification unless otherwise specifically
specified.
3.4 Design and construction. The splices shall be of the construction, weight, and
physical dimensions specified (see 3.1 and 6.1).
Splice designs may be single fiber or multiple fibers.
3.4.1
General.
3.4.1.1 Fiber splice. The fiber splice shall include the waveguide splice and the
fiber splice housing (see 6.1).
3.4.1.2 Waveguide splice. The waveguide splice shall optically align the core and
cladding of the optical fiber (see 3.6.1 and 3.6.3).
3.4.1.1.2 Fiber splice housing. The fiber splice housing shall restore the
environmental and mechanical integrity of the coating or buffer of the optical fiber.
3.4.1.2 Cable splice. The cable splice shall include the cable splice closure and
the fiber splices. The cable splices shall seal the cables to meet the environmental
requirements specified herein.
3.4.1.2.1 Cable splice closure. The cable splice closure shall include cable seals
necessary to restore mechanical strength and environmental protection to the cable.
The cable splice closure shall seal the fiber splice against moisture and
contamination as specified herein.
The splices shall require no preventative maintenance.
3.4.2
Maintainability.
3.4.3 Interchangeability. All splice parts having the same military part number
shall be physically and functionally inter-changeable without need for modification of
such items or of the splicing equipment.
3.4.4 Metals. Metals shall be corrosion resistant. Unless otherwise specified (see
3.1), metals shall be nonmagnetic, and all exposed corrosion resistant steel parts
shall have a passivated surface that is compatible with external coatings or platings
as specified (see 3.1).
3.4.5 Dissimilar metals. The use of dissimilar metals in intimate contact should be
avoided. When dissimilar metals are used in intimate contact with each other,
protection against electrolysis and corrosion shall be provided.
