Abstract: Optical fiber connectors configured to allow ease of change of the connector polarity by providing lockable outer housing. In an embodiment, an optical fiber connector comprises an inner housing, a key disposed along a side of the inner housing, wherein the inner housing includes at least one protrusion configured to lock the key, and an outer housing disposed around at least a portion of the inner housing and the key. The outer housing may be configured to be pulled rearward relative to the inner housing, and further configured to unlock the key to allow slideably moving the key from a first position to a second position.

Abstract: Optical fiber connectors configured to allow ease of change of the connector polarity by providing lockable outer housing. In an embodiment, an optical fiber connector comprises an inner housing, at least one key configured to move along the inner housing so as to change a polarity of said optical fiber connector, and an outer housing disposed around at least a portion of the inner housing and configured to slide in a longitudinal direction so as to expose at least a portion of said at least one key, wherein the outer housing includes a flexible portion configured to lock to the inner housing so as to retain the outer housing in a pulled back position relative to the inner housing.

Abstract: Connector assemblies having an adjustable polarity are described. For example, at least two ferrules may be arranged in a housing of the connector assembly within independent frame plugs in a certain polarity. A top portion of the housing may be removed to allow access to the frame plugs. Accordingly, an installer may open the housing, switch the polarity of the ferrules, and then re-couple the top portion to the housing. In another example, the connector assembly may include a latch that may rotate about the connector assembly from a first polarity position to a second polarity position. The connector assembly may include a compression element that may facilitate the rotation of the latch when the compression element is compressed. In this manner, the latch may be rotated to a different polarity position to allow the connector assembly to be connected to an adapter using a different polarity.

Abstract: 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.
