MIL-PRF-24623C
3.6.6 Ambient light susceptibility. When tested in accordance with 4.7.3.6, the
optical power of the light from the fibers (after accounting for cable losses and
optical junction losses between the fiber and the detector) shall be less than -50 dBm
(dB ref. to 1 mw).
Environmental requirements.

3.7.1 Environmental properties. The splice shall meet all the specified
requirements (see 3.1), during the specified operating environments and after the
specified storage environments. The operating and storage temperature ranges shall be
as specified (see 3.1) in table I.

3.7.2 Life aging. When tested in accordance with 4.7.4.1, the splices subjected to
these specified accelerated aging exposures shall not exhibit visual evidence of
dimensional change, opening of seals, cracking or crazing of components or finishes,
identification marking impairment, leakage of waterproofing compounds or other defects
detrimental to their operation. The splice shall meet the requirements of 3.6.2 after
the test.
3.7.3 Thermal shock. When tested in accordance with 4.7.4.2, a post test visual
examination of the test splices shall reveal no leakage of waterproofing compounds or
other apparent loss of sealing capability, no surface or identification marking
impairment, nor any damage detrimental to the operation of the splice. The splice
shall meet the requirements of 3.6.2 after the test.
3.7.4 Temperature/humidity cycling. When tested to high humidity and cyclic
temperature exposures in accordance with 4.7.4.3, the splice parts shall not swell,
neither shall they have impaired identification markings, nor shall they degrade such
that splice performance is impaired. The splice shall meet the requirements of 3.6.2
during and after the test.
3.7.5 Salt spray (corrosion) (for cable splice only). When tested in accordance
with 4.7.4.4, no visible evidence of salt penetration into splice enclosures shall be
observed and no corrosive effects shall be seen on the external splice parts.
3.7.6 Water pressure (for cable splice only). When tested in accordance with
4.7.4.5., visual inspection of the test splice shall reveal no penetration of water
into the sealed region of the splice.
3.7.7 Freezing water immersion (for cable splices only). When tested in accordance
with 4.7.4.6, the splices shall not be damaged during exposure. The splices shall
meet the optical requirements of 3.6.2 during and after the test.
3.7.8 Sand and dust (for cable splice only). When tested in accordance with
4.7.4.7, the splices shall not be damaged during exposure. The splices shall meet the
optical requirements of 3.6.2 during and after the test.
3.7.9 Nuclear radiation resistance (for lensed splice only). When tested in
accordance with 4.7.4.8, the splices shall not be damaged during exposure. The
performance requirements of 3.6.2 shall be met during and after the test.
3.7.10 Fluid immersion (for cable splice only). When tested in accordance with
4.7.4.9, visual examination of the splice shall reveal no swelling or softening of
