Abstract: In accordance with the following description, an optical communication connector includes a ferrule having retractable alignment pins that are actuable between an extended position and a retracted position. For example, the connector may include an inner housing assembly having optical fibers and an outer housing positioned over the inner housing assembly. The outer housing is shaped to be removable from the inner housing assembly, which has a movable pin clamp mechanically coupled to alignment pins for aligning the connector with another connector. The pin clamp may be slid from a first position (corresponding to a male gender) to a second position (corresponding to a female gender). Separately or in combination with changing gender, the polarity of a communication connector may be changed due to its inclusion of an asymmetric polarity-changing feature that is actuable by an installer to change a polarity of the communication connector.
