TFOCA

TFOCA stands for Tactical Fiber Optic Cable Assembly. Unlike normal fiber optics, these are made for high strength, as they're meant to be used in harsh environments. TFOCA is used in aerospace, oil-drilling, military, and water purification applications. The connectors are generally hermaphroditic, so any two can be connected, regardless of gender. Several US Department of Defense specifications and military specifications apply to TFOCA, including DOD-1678, MIL-C-83526/12-01, and MIL-STD-810C. One of the unique features of these connectors is that they can be repaired in the field with nothing more than a screwdriver. Normal (civilian) fiberoptic connectors are much less expensive, but require a variety of specialized tools to assemble.
