Abstract: A re-terminable, no-crimp ST-type optical connector assembly includes a spring-loaded ferrule holder assembly and a reusable activation system for termination of the assembly. The optical connector can be terminated by a suitable cam activation tool. The connector includes a housing, such as a bayonet, matable to a mating adapter, a backbone retained within a rear of the housing, a ferrule holder provided within the backbone, and a cam provided between the ferrule holder and the backbone. The ferrule holder includes an alignment key exposed to mate with a cam activation tool to lock rotation of the ferrule holder relative to other connector components. The cam includes a cam activation cutout at a front face thereof that mates with a cam activation tool interface to enable rotation of the cam between de-activated and activated positions, the cam activation cutout also receiving the alignment key of the ferrule holder therethrough.

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.
