REQUIREMENTS:
Temperature: -28°C to +65°C operating, -40°C to +70°C non-operating, -40°C
to +70°C storage.
Design and construction:
Dimensions and configuration: See figures 1 and 2 and table I. Termini
may have either flat or radiused end faces. Regardless of the end face
geometry, the terminus shall meet the requirements of this specification
when terminated using the procedures specified in MIL-STD-2042.
Weight:
1.0 gram maximum.
Adhesives:
Use MIL-PRF-24792 or as approved by the qualifying activity.
Material:
Ferrule: Ferrule materials shall have similar performance to zirconia.
Termini shall meet all of the requirements of this specification when mated
to qualified pin termini utilizing a zirconia ferrule.
Tools:
See table II.
Mating termini:
MIL-PRF-29504/14.
Crimp sleeve: The crimp sleeve shall accept single fiber cable with a
maximum outer diameter of 2.4 mm (.094 in). The terminus shall meet all
requirements when the crimp sleeve is assembled to the terminus using a hex
crimp die with flats measuring 2.400 mm + .025 mm (.0945 in + .001 in)
across and 6.6 mm (.260 in) maximum long. Crimp sleeve is to be supplied
with termini when specified in PIN.
Circular runout: The circular runout of the ferrule bore to the ferrule
outer diameter shall be not greater than 1.0 micrometer.
Optical performance:
Insertion loss: The initial insertion loss of a mated pin and socket shall
be not greater than 0.75 db. The maximum insertion loss of a mated pin and
socket at any time during testing shall be not greater than 1.25 db.
Environmental/mechanical: Termini shall be tested to the following MIL-PRF-
28876 environmental and mechanical requirements. Change in optical
transmittance and optical discontinuity requirements shall be as specified
in MIL-PRF-28876.
