A fiber optic ferrule coupling system including a ferrule interface plate having a ferrule port extending therethrough and a pocket in a side of the ferrule interface plate adjacent to the ferrule port, wherein a spring element disposed in the pocket partially protrudes into the port and applies an adjustable spring force to a ferrule connector inserted in the ferrule port via a spring cover fittable within the pocket.

The disclosure describes a method for assembling an optical coupler, the method may include (a) inserting optical fibers of an array of optical fibers through an array of openings of a mount of the optical coupler so that tips of the optical fibers pass through the array of openings of the mount and reach an adaptor; wherein the array of openings of the mount exhibit a first positioning accuracy; (b) using the adaptor to position the tips of the optical fibers at predefined locations, at a second positioning accuracy that is higher than the first positioning accuracy; (c) fixing the tips of the optical fibers to the mount while maintaining the tips of the optical fibers at the predefined locations; and (d) detaching the mount from the adaptor.

A manufacturing method of a set of connectors includes: a step of measuring an emitting direction of light emitted from a plurality of ferrules; a step of grouping the plurality of ferrules into a first group or a second group, based on whether the emitting direction is right or left of a straight line connecting a reference fitting portion closest to the emitting direction of the light and an optical axis; a step of fabricating a plug using the ferrule belonging to the first group; and a step of fabricating a receptacle using the ferrule belonging to the second group.

A system for automatically inserting fibers is disclosed. The system comprises a cable having a plurality of fibers, a ferrule having a plurality of bores, a moving mechanism movable in a first direction, a second direction, and a third direction that are perpendicular to each other, a cable holder mounted on the moving mechanism and holding the cable, and a vision device. The moving mechanism moves the cable holder under the guidance of the vision device to align the plurality of fibers with the ferrule and insert the plurality of fibers into the plurality of bores.

The present disclosure relates to a fiber optic connector designed to improve the insertion of an optical fiber within the fiber optic connector. The fiber optic connector may include a lead-in tube that makes the insertion of an optical fiber easier. That is, the lead-in tube may be molded over a ferrule hub to fully encapsulate a rear end thereof such that the optical fiber does not snag or hang up during insertion.

A tunable optical fiber connector for use with an optical fiber cable that supports an optical fiber is disclosed. The connector includes a ferrule, an inner housing and an outer housing. The ferrule has a diameter dF, an outer surface, and an axial bore configured to operably support a bare fiber portion of the optical fiber. The inner housing has an interior and a front-end section that defines a front end of the inner housing. The interior of the inner housing supports the ferrule so that the ferrule front end extends beyond the inner housing front end by a distance DF, wherein dF≦DF≦4.Math.dF. The outer housing has an interior configured to receive the inner housing in one of at least four possible orientations of the inner housing. Cable assemblies and sub-assemblies, as well as connector sub-assemblies, are also disclosed.

An embodiment relates to a method for manufacturing an optical module having an MCF and two connection components, and enables rotational alignment of the MCF to be implemented with high accuracy even in short-haul optical wiring. The MCF is arranged in a region between the two connection components while an end thereof projects from one connection component. As this arrangement state is maintained, array positions of cores in the projecting end are observed from a side face and the MCF is rotationally aligned by a rotation grasp jig grasping the projecting end to adjust the array positions of the cores, based on the observation result.

The present disclosure relates to a multi-core optical fiber cable (MCF). In some embodiments, an MCF comprises a plurality of cores surrounded by a cladding and a coating surrounding the cladding, wherein a refractive index of one or more of the plurality of cores is greater than a refractive index of the cladding. The MCF further comprises a probe comprising a probe tip coupled with a distal end of the MCF and a lens located at a distal end of the probe tip. In some embodiments, the lens is configured to translate laser light from the distal end of the MCF to create a multi-spot pattern of laser beams on a target surface and a distal end of the MCF terminates at an interface with the lens.
