US Patent 9709753 Polarity changeable LC duplex adapter

A multi-polarity fiber optic adapter is configured to provide a plurality of connector polarity options. The adapter includes a housing and a plurality of ports, each port configured to receive and establish an optical connection with a ferrule of a fiber optic connector. The adapter further includes a plurality of first-polarity connector clip assemblies positioned within the housing such that, when the fiber optic connector is inserted into the adapter in a first position, the fiber optic connector is engaged with the first-polarity connector clip assemblies, thereby establishing a first-polarity connection. The adapter also includes a plurality of second-polarity connector clip assemblies positioned within the housing such that, when the fiber optic connector is inserted into the adapter in a second position, the fiber optic connector is engaged with the plurality of second-polarity connector clip assemblies, thereby establishing a second-polarity connection.
