A fiber optic pigtail assembly that includes a plurality of optical fibers and at least one optical connector. The optical fibers each have a first end opposite a second end. The plurality of optical fibers are ribbonized together from the first end of each of the plurality of optical fibers partway toward the second end of each of the plurality of optical fibers and form a ribbonized end portion. The at least one optical connector is connected to the second end of each of the plurality of optical fibers. A loose portion of the plurality of optical fibers is positioned between the at least one optical connector and the ribbonized end portion.

A termination enclosure includes a chassis configured to hold optical terminations and optical splices. The optical splices are mounted to a removable splice drawer. In certain examples, the splice drawer is removed through a rear of the chassis while the optical terminations remain at the chassis. Optical splices can be made at a workstation remote from the chassis and stored in the splice drawer, which is inserted back into the chassis.

An optical splitter module for splitting an input signal from an input optical fiber is provided. The optical splitter module includes the input optical fiber, output optical fibers, and a splitter device configured to split the input signal from the input optical fiber into a plurality of output signals that are each directed into one of the output optical fibers. The optical splitter module also includes a fanout device defining openings that are each configured to receive one of the output optical fibers. The optical splitter module defines an internal volume and an exit cavity. The input optical fiber, the output optical fibers, the splitter device, and the fanout device are each received in the internal volume. The fanout device defines a side length, the exit cavity defines a width, and the side length of the fanout device is greater than the width of the exit cavity.

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 m) to a second pitch (e.g., a coated fiber diameter of 250 m). 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.

A shuffle cable provides optical fibers in color-coded groups to facilitate the break-out of optical fibers into standard multi-color, multi-signal ribbon cables within the context of spine-leaf cabling.

A fiber optic furcation assembly includes a main fiber optic cable structure, a plurality of furcation tubes, and a housing with a cavity including a transition portion. A plurality of optical fibers each continuously and uninterruptedly extends through an end portion of a jacket of the main fiber optic cable structure, the transition portion of the cavity of the housing, and a respective one of the plurality of furcation tubes. In one embodiment, the cavity includes a securing portion including a plurality of protrusions. The plurality of protrusions defines a plurality of locating channels and at least one securing channel that intersects the locating channels. Bonding material is positioned within the securing channel and bonds the plurality of furcation tubes to the plurality of protrusions. In another embodiment, a cable mount includes a housing attachment, a cable jacket attachment, and a passage. The housing attachment is mounted within a port of the housing. Each optical fiber also extends through the passage of the cable mount, respectively.

An optical cable includes a main body and a termination segment extending from an end of the main body. The main body includes middle portions of optical fibers. The termination segment includes end portions of the optical fibers and multi-fiber connectors attached to the end portions of the optical fibers. The multi-fiber connectors are staggered along a length of the termination segment.

The FIFO device includes an MCF, a first lens having a first optical axis parallel to a center axis of the MCF, a group of second lenses including the same number of second lenses having a second optical axis parallel to the first optical axis as cores of the MCF, and a group of single-core optical fibers including the same number of single-core optical fibers as the second lenses. An end face of each single-core optical fiber is obliquely polished so as to incline in a predetermined inclination direction with respect to a plane orthogonal to the center axis by a predetermined polishing angle. Oblique polishing directions of surrounding single-core optical fibers are set so that the corresponding second lenses are positioned closer to the first optical axis or to the first lens compared to their positions at the time when the surrounding single-core optical fibers are not obliquely polished.
