1. A duplex fiber optic connector assembly suitable for polarity reversal, comprising:
a first fiber optic connector subassembly comprising a first ferrule retaining a first optical fiber;
a second fiber optic connector subassembly comprising a second ferrule retaining a second optical fiber;
a primary housing defining a first aperture and a second aperture for respectively receiving portions of the first and the second fiber optic connector subassemblies such that portions of the first and the second fiber optic connector subassemblies protrude in a forward direction from the primary housing, the primary housing further comprising:
at least one engagement feature that is manually actuatable; and
a base member and a cover member, wherein each of the base member and the cover member define complementary portions of the first aperture, and wherein each of the base member and the cover member define complementary portions of the second aperture; and
a latch housing configured to matably receive the primary housing when the primary housing is an a first, upwardly-facing configuration and when the primary housing is in a second, downwardly-facing configuration, the latch housing comprising (i) at least one receiving feature configured to receive the at least engagement feature to permit releasable engagement between the primary housing and the latch housing, and (ii) a latch mechanism that is manually actuatable and configured to permit releasable engagement between the latch housing and a fiber optic adapter housing separate from the duplex fiber optic connector assembly;
wherein, upon manual actuation of the at least one engagement feature, the duplex fiber optic connector assembly is configured to permit the primary housing to be removed from the latch housing by movement of the primary housing in a rearward direction that opposes the forward direction; and
wherein the cover member comprises a first fiber polarity indicator, the base member comprises a second fiber polarity indicator, and the latch housing defines a window configured to (i) permit the first fiber polarity indicator to be visible when the primary housing is the first, upwardly-facing configuration, and (ii) permit the second fiber polarity indicator to be visible when the primary housing is in the second, downwardly-facing configuration.
