Abstract

Indexable optical fiber connectors, optical connector arrays, and optical connector systems are disclosed. According to one embodiment, an optical fiber connector includes a connector body comprising an optical coupling face and a connector housing that surrounds the connector body. The connector housing includes a first interconnecting surface having an indentation arraying feature, and a second interconnecting surface having a protrusion arraying feature. The first interconnecting surface and the second interconnecting surface are orthogonal to the optical coupling face. The indentation arraying feature is configured to mate with a corresponding protrusion arraying feature of a first adjacent interconnecting optical fiber connector by a non-locking engagement relationship. Similarly, the protrusion arraying feature is configured to mate with a corresponding indentation arraying feature of a second adjacent optical fiber connector by a non-locking engagement relationship.
