1. A fiber optic adapter for coupling together two fiber optic connectors, the fiber optic adapter comprising:
an adapter body including first and second ends, the first end defining a first connector port and the second end defining a second connector port, the first and second connector ports being aligned along an axis that extends between the first and second ends of the adapter body and through the first and second connector ports, the adapter body defining a central axis that extends through the first and second connector ports, the first and second connector ports each defining an oblong shape having perpendicular major and minor axes;
connector retention latches integrated with the adapter body at the first and second connector ports, the connector retention latches of each of the first and second connector ports being located on opposite sides of their respective first or second connector port and being aligned along the major axis of their respective first or second connector port;
an end cap having an end cap body that mounts at the first end of the adapter body, the end cap also including internal shutters pivotally connected to the end cap body, the internal shutters being configured to pivot relative to the end cap body between a closed position in which the shutters block the first connector port and an open position in which the shutters are pivoted inside the end cap body to allow a fiber optic connector to be received within the first connector port; and
wherein the fiber optic adapter is convertible between a type A polarity configuration and a type B polarity configuration, and wherein the internal shutters are secured to the end cap body by a pivotal, snap-fit connection.
