An optical fiber bundle structure includes: plural optical fiber core wires; a crossing preventing member; and a grasping member. Further, the crossing preventing member has slits and the widths of the slits positioned at the respective sides are each equal to or larger than a difference between: a length of one side of a polygon circumscribing the plural optical fiber core wires at a hindmost end portion of the slits at the trailing end; and a length of one side of a polygon circumscribing the plural optical fiber core wires at the leading end.

A fiber optic ribbon is disclosed and includes a plurality of optical fibers extending along a first axis and arranged along an orthogonal second axis at a pitch P. Each optical fiber includes a core surrounded by a cladding surrounded by a buffer, the buffer has a nominal diameter D0 substantially equal to P. The buffer is stripped between a buffer-end location on the fiber and a free end of the fiber to form a stripped section. The buffer is distorted at the buffer-end location, such that at the buffer-end location, a width W of the buffer in the second axis is less than D0.

A light coupling element including a plurality of waveguide attachment features and a light redirecting member is described. Each attachment feature has an entrance end opposite a terminal end. The entrance ends are arranged at a pitch Pe. The light redirecting member is disposed closer to the terminal ends, and farther from the entrance ends, and includes an input surface, a reflecting side and an exit surface. When a waveguide is attached at each attachment feature, a central light ray emitted by each waveguide enters the light redirecting member through the input surface, is redirected by the reflecting side and exits the light redirecting member at the exit surface, the central light ray intersecting the exit surface at an exit point, each attachment feature corresponding to a different exit point at the exit surface. The exits points are arranged at a pitch Px not equal to Pe.

Embodiments of the present invention are directed to an interlacing boot and methods of using the same to automatically interleave optical fibers in a two-row array, such from a two rows ferrule. In a non-limiting embodiment of the invention, the optical fibers are inserted into a first end of an interlacing boot in a first direction. The interlacing boot can include a guiding structure having one or more channels. Each channel can be adapted to receive a single optical fiber. Each channel can include a first end and a second end, and the second end can be offset with respect to the first end in a second direction orthogonal to the first direction. The interlacing boot can be pushed towards the ferrule to feed the optical fibers through the guiding structure. The first row of fibers can be physically offset from and interlaced with the second row of fibers by the guiding structure.

An optical fiber arranging tool has a base, a top surface, and a recessed channel extending along the base and has a plurality of ribs disposed within the recessed channel. The plurality of ribs have a pitch of 250 microns creating a plurality of grooves for receiving the optical fibers. The tool may also have a latch, there being a slot between the top surface of the base and an underside of the latch and in communication with the recessed channel. A method for aligning the optical fibers includes sliding individual optical fibers into a slot and the recessed channel, moving an object along the optical fibers in the recessed channel, passing the individual optical fibers through a respective one of a plurality of grooves created by ribs within the recessed channel and maintaining the individual optical fibers at a distance of 0.250 mm.

An optical fiber cable includes: a small-diameter optical fiber including a core and a cladding portion made of glass and having a cladding diameter of 120 μm or less; a normal optical fiber that is optically connected to at least one end of the small-diameter optical fiber, includes a core and a cladding portion made of glass, and has a cladding diameter conforming to a standard of 125 μm; an optical coupling mechanism provided between the small-diameter optical fiber and the normal optical fiber; and a sheath covering an outer periphery of the small-diameter optical fiber only, among the small-diameter optical fiber and the normal optical fiber. Further, the end of the small-diameter optical fiber is positioned outside the sheath.

A fixture is for forming a fiber optic array that defines a plurality of discrete fibers extending from a spaced-apart arrangement to a consolidated arrangement wherein the fibers are layered next to each other for a further ribbonizing process. The fixture includes a pair of contact blades that are configured to slide along a direction transverse to the longitudinal axes of the fibers for consolidating the fibers.

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. The present disclosure also relates to a fiber optic connector including a connector body and a rear connector piece that is secured to the connector body by a snap-fit connection. The rear connector piece can be configured for attachment to a fiber optic cable. The rear connector piece can be secured to the connector body by a snap-fit connection. The rear connector piece can have a snap-fit interface compatible with a number of different styles or types of connector bodies to promote manufacturing efficiency.

An optical fiber fan-out assembly includes multiple optical fibers arranged in a one-dimensional array in a transition segment in which spacing between fibers is varied from a first pitch (e.g., a buffered fiber diameter of 900 μm) to a second pitch (e.g., a coated fiber diameter of 250 μm). A polymeric material encapsulates the optical fibers in the transition segment, and the assembly further includes multiple optical fiber legs each terminated with a fiber optic connector. Optical fibers extending beyond a boundary of the polymeric material are subject to being mass fusion spliced to another group of multiple optical fibers, and the fusion splices encapsulated with polymeric material, to form a fiber optic cable assembly. Methods for fabricating multi-fiber assemblies providing fan-out functionality are further provided, and the need for furcation tubes is avoided.
