A fiber optic receptacle and plug assembly includes a fiber optic
receptacle adapted to be mounted within a connector port of a network
connection terminal and a fiber optic plug mounted upon an end of a fiber
optic cable, wherein the fiber optic receptacle and the fiber optic plug
comprise complimentary alignment and keying features that allow the fiber
optic receptacle to receive only a fiber optic plug of like ferrule
configuration. The fiber optic receptacle includes an alignment sleeve
insert operable for receiving and optically connecting at least one
receptacle ferrule and at least one opposing plug ferrule. The receptacle
is suitable for use in enclosures requiring a minimal receptacle
penetration depth, wherein the fiber optic receptacle comprises a
shoulder that is secured against an inner wall of the enclosure to
provide strain relief against cable-pulling forces of up to about 600
lbs.
