Field repairable hermaphroditic connector

A hermaphroditic cable or waveguide termination device for optical fibers, the termination device comprising:

• a housing having locking holes, the housing having a front end, the front end having mating structures which are substantially identical to and mateable with a mating structure of a front end of another housing;
• and
• a plug insert removably provided in the housing through the front end of the housing, the plug insert having optical connector ports, each of the optical connector ports dimensioned so as to receive a respective optical assembly where each optical assembly has a respective optical ferrule which aligns a respective optical fiber, the plug insert having a substantially cylindrical surface and a first surface substantially perpendicular to the cylindrical surface, the plug insert having nub features provided in a region of the cylindrical surface for mating with the locking holes, the first surface having a first ferrule port and a second ferrule port, the first ferrule port having a plug insert extension projecting from the first surface, the second ferrule port dimensioned so as to receive a plug insert extension of another plug insert, the first optical connector receiving port communicating with the second ferrule port, the second optical connector receiving port communicating with the first ferrule port.
