摘要： Attachment bodies, optical cable assemblies, and methods for fabricating optical cable assemblies for mating with compact multiports or terminals are disclosed. In one embodiment, an attachment body includes a body defining a passageway therein. The body includes a cable insertion portion, wherein the cable insertion portion is round and defines a cable insertion face having a first area, a cable securing portion adjacent to the cable insertion portion, and a port insertion portion adjacent to the cable securing portion. The port insertion portion includes a distal end that is non-round. The distal end defines a port insertion face having a second area that is smaller than the first area.

摘要： The present disclosure relates to a process by which an optical fiber array is cleaved with a laser-cleaving apparatus. The coating material is stripped or removed from a section of an optical fiber array; a coated or ribbonized section of the optical fiber array is secured in a holder; the holder is aligned inside the laser-cleaving apparatus; the laser cleaves the stripped ends of the fibers in the optical fiber array; the laser-cleaved ends of the optical fibers are then mechanically separated to remove the free ends from the optical fibers in the optical fiber array, leaving a cleaved array of optical fibers. The cleaving process enables the optical fiber array to be cleaved at flexible locations along an optical fiber ribbon or optical fiber cable with no swelling, minimal cleave angle variation across the cores of the optical fibers, a controlled surface roughness of the optical fiber end-faces, and high process yield.

摘要： Fiber array spacers, optical fiber assemblies, optical assemblies, and methods for fabricating optical assemblies are disclosed. In one embodiment, an optical fiber assembly includes a fiber array spacer and a fiber ribbon having an array of optical fibers. The fiber array spacer has an array of spacer fibers, wherein individual spacer fibers of the array of spacer fibers are bonded to one another, and a diameter of the individual spacer fibers determines a height of the fiber array spacer. Each optical fiber of the array of optical fibers has an glass portion. The glass portion of each optical fiber is bonded to the fiber array spacer such that a longitudinal axis of the individual spacer fibers is transverse to a longitudinal axis of individual optical fibers of the fiber ribbon.

摘要： An apparatus comprises a first fastener part having a first set of mating features and a second fastener part having a second set of mating features. Coupling the first set of mating features with the second set of mating features, such that the first set of mating features contacts and at least partially overlaps the second set of mating features, forms a fastener having a channel with a hexagonal cross-section. The channel is configured to receive a plurality of fibers. Coupling the first fastener part to the second fastener part clamps the plurality of fibers in a hexagonal packing configuration.
