1. A fiber optic adapter for use with a fiber optic connector having a plug frame with a stop and a shell, the fiber optic adapter comprising:
a housing that has a cavity at one end for receiving the fiber optic connector, the housing having at least one divider defining a passageway adjacent the cavity, the at least one divider having a through-slot between the passageway and the cavity;
a sliding latch that is configured to contact the fiber optic connector when the fiber optic connector is inserted into the cavity, the sliding latch being movable within the housing from an extended position to a latched position;
a connector latch that is configured to engage the stop when the sliding latch is at the latched position, the connector latch having an engagement arm from which a wedge-shaped tab extends to engage the stop and a protrusion extending from the engagement arm in a direction opposite the wedge-shaped tab, the protrusion being positioned to extend through the through-slot when the fiber optic connector is inserted into the cavity; and
one or more springs that are operably coupled to the sliding latch, at least one spring of the one or more springs being compressible during insertion of the fiber optic connector into the cavity,
wherein when the fiber optic connector is inserted into the cavity the fiber optic adapter indicates when the sliding latch is not at the latched position.
