An intermediate portion of the fiber passage is positioned between the first and the second ends. The intermediate portion is adapted to align the first and the second optical fibers between the first and the second alignment blocks. A first portion of the fiber passage is positioned between the first end and the intermediate portion of the fiber passage. The first portion extends between the first alignment block and the first gel block. A second portion of the fiber passage is positioned between the second end and the intermediate portion of the fiber passage. The second portion extends between the second alignment block and the second gel block. End portions of the first and the second optical fibers may be cleaned when slid between the alignment blocks and the gel blocks. The fiber passage may include an undulating portion.

An optical fiber connection system includes a first and a second optical fiber, each with end portions that are terminated by a first and a second fiber optic connector, respectively. A fiber optic adapter connects the first and the second fiber optic connectors. A fiber alignment apparatus includes V-blocks and gel blocks. Each of the fiber optic connectors includes a connector housing and a sheath. The end portions of the optical fibers are positioned beyond distal ends of the respective connector housings. The sheath is slidably connected to the connector housing and slides between an extended configuration and a retracted configuration. The sheath covers the end portion of the respective optical fiber when the sheath is at the extended configuration and exposes the end portion when at the retracted configuration. The end portions of the optical fibers are cleaned when slid between the V-blocks and the gel blocks.

A connection system includes an optical connector assembly; and an optical plug. The connector assembly includes a stack of gel-groove assemblies and a spring assembly mounted within a housing. Each of the gel-groove assemblies includes a first gel block at a first axial end, a second gel block at a second axial end, and a fiber mating region between the first and second gel blocks. The optical plug including sub-modules over-molded over arrays (e.g., ribbons) of the optical fibers. Each sub-module defines notches for receiving latches of the spring assembly when the optical plug is coupled to the first axial end of the optical adapter. Bare optical fibers extend from the plug, pass through the first axial gel block, and enter the fiber mating region when the plug is coupled to the adapter.

The present disclosure relates to a fiber optic cable and connector assembly including a fiber optic cable and a ferrule-less fiber optic connector. The ferrule-less fiber optic connector includes a main connector body including a distal end and a proximal end. The fiber optic connector also includes a fiber fixation component that mounts within the main connector body and that axially fixes a portion of an optical fiber of the fiber optic cable within the main connector body. The optical fiber includes a bare fiber portion that extends distally beyond the fiber fixation component and includes a free-end portion located at the distal end of the main connector body. The free-end portion is not supported by a ferrule. The optical fiber is anchored relative to the fiber fixation component before the fiber fixation component is mounted within the main connector body.

A fiber array unit (FAU) includes a substrate, a plurality of optical fibers, and a lid. The substrate includes: an optical window extending through a layer of non-transparent material, a plurality of grooves, and an alignment protrusion configured to mate with an alignment receiver. The plurality of optical fibers are disposed in the plurality of grooves. The alignment protrusion is configured to align the plurality of optical fibers with an external device when mated with the alignment receiver. The plurality of optical fibers is disposed between the lid and the substrate.

An optical fiber connector is provided. A receptacle has an angled interior surface that acts to guide an optical fiber into the correct position as a jack is inserted into the receptacle.

The present disclosure relates to connector ports with shutters configured to inhibit dust intrusion by including peripheral regions that oppose undercut portions of the connector port when the shutter is closed. The present disclosure also relates to fiber optic connectors having latching configurations with double latches for retaining the fiber optic connectors in connector ports. The present disclosure also relates to a fiber optic connector including a plurality of stacked fiber carrier modules.
