Abstract: A universal breakout harness for reversing the polarity of optical fibers includes a multi-fiber connector having a plurality of optical paths, an optical ribbon having a plurality of optical fibers disposed in the optical paths of the multi-fiber connector, and a plurality of optical fiber connectors opposite the multi-fiber connector defining a plurality of pairs of optical fiber paths. The optical fibers are separated and routed between the optical paths of the multi-fiber connector and the pairs of optical paths defined by the plurality of optical fiber connectors such that the optical fibers in at least one of the pairs of optical paths are selected from optical fibers disposed in optical paths of the multi-fiber connector that are not immediately adjacent to each other. The universal breakout harness is used in methods of implementing reverse-ribbon positioning in a cabling system and transitioning ribbon cabling into multiple duplex systems.

Abstract: An optical interconnection module having: an enclosure defining walls and a cavity within the walls for receiving and supporting optical fibers and connectors; an optical interconnection section formed in a wall of the module, the optical interconnection section having a multi-fiber connector with multiple optical paths formed therein, the optical paths being arranged in a generally planar array with the paths being immediately adjacent to at least one other optical path for optical alignment with optical fibers in an optical fiber ribbon; an optical connector station formed in a wall of the module having a plurality of optical fiber connectors; the optical paths and the optical connectors being optically interconnected by optical fibers disposed in the cavity, fiber pairs being formed by the optical fibers, at least one of the fiber pairs being routed to a respective connector station that is in optical communication with the optical paths.
