MIL-SPEC Connectors For Sale
MIL-SPEC connectors are typically plugs or so-called male connectors with a protruding ferrule that holds the fibers and aligns two fibers for mating. They use a mating adapter to mate the two harsh environment connectors that fits the securing mechanism of the connectors (bayonet, screw-on or snap-in). A primary specification issue for military connectors is insertion loss, i.e., the amount of light lost in the connection expressed in dB.
These military connectors, and their evolutionary derivatives, are often called Military Standard, "MIL-STD", or (informally) "MIL-SPEC" connectors. They are now used in aerospace, industrial, marine, and even automotive commercial applications.
