Abstract

A fiber optic module assembly that may be pulled from a first location to a second location by a pulling means, the module assembly defining a pulling feature. The assembly may further be installed directly into a mounting structure for use as a patch panel. The fiber optic module assembly may be attached in a vertical orientation, facilitated by an articulated strain relief boot that pivots and rotates for cable management, which reduces the vertical footprint of the fiber optic module assembly. Embodiments of the fiber optic module assembly may be connected to the rear or side of a mounting structure for optical connection to pigtailed modules. The fiber optic module assembly may have a modular connector interface for mating dissimilar fiber optic connector assemblies.
