Flexible, non-preferential bend jackets for optical fiber cables
Embodiments of the disclosure relate to an optical fiber cable. The optical fiber cable includes a cable jacket having an inner surface and an outer surface in which the inner surface defines a central bore along a longitudinal axis of the optical fiber cable and the outer surface defines the outermost extent of the cable. The optical fiber cable also includes at least one access feature disposed in the cable jacket between the inner surface and the outer surface. Further included are a first plurality of optical fiber bundles. Each optical fiber bundle includes a second plurality of optical fiber ribbons that has a third plurality of optical fibers arranged in a planar configuration. The optical fiber cable bends uniformly in all directions transverse to the longitudinal axis of the optical fiber cable.

High fiber density ribbon cable
An optical fiber cable includes a jacket and a plurality of stranded core subunits, each core subunit comprising a flexible sheath and a plurality of ribbons arranged in a ribbon group, wherein each ribbon of the plurality of ribbons comprises a plurality of connected fibers such that 50-70% of the cross-sectional area inside the sheath is occupied by the connected fibers. The flexible sheath may be an extruded PVC material that conforms to the shape of the ribbon stack and keeps all of the ribbons acting as a unitary body during bending.
FIBER ORGANIZER
A method organizes fibers. A plurality of fibers is received into a first assembly. An initial sequence of the plurality of fibers in the first assembly is obtained. A set of key combinations is identified from the initial sequence and a predetermined sequence. A second assembly is slid across the first assembly. The set of key combinations is actuated to move the plurality of fibers from the first assembly to the second assembly and order the plurality of fibers in the second assembly in the predetermined sequence.
Optical fiber ribbon and optical fiber cable
An optical fiber ribbon includes a plurality of optical fiber cores arranged in parallel spaced from each other; and a tape forming member having a coating portion covering an outer circumference of the optical fiber cores, and a coupling portion, integrally formed with the coating portion, intermittently coupling adjacent optical fiber cores, wherein the coating portion has an opening portion to expose a part of surfaces of the optical fiber cores, and at least a part of the coating portion is continuous in a longitudinal direction of the optical fiber cores.
OPTICAL FIBER CABLE, OPTICAL FIBER RIBBON, METHOD OF INSTALLING OPTICAL FIBER CABLE, AND OPTICAL TRANSMISSION SYSTEM
An optical fiber cable includes: a multi-core optical fiber including a cladding and cores in the cladding; and a piece of arrangement information associated with the multi-core optical fiber and with a core arrangement of the cores in a cross-section of the multi-core optical fiber.

Systems and methods for removing coating from an optical fiber
Methods and systems for removing coatings from optical fibers. A system includes a gas source for providing gas, and a heater configured to heat the gas. The system includes a holder comprising first and second attachment features. The attachment features secure a coated optical fiber along a removal path. The system includes at least one nozzle connected to the gas source. The at least on nozzle is aimed in a nozzle direction that is towards the removal path at a pitch, such that the nozzle is non-perpendicular towards the removal path. The nozzle directs a continuous stream of the heated gas towards the coated optical fiber causing the coating of the coated optical fiber to be removed. The methods and systems may employ a second nozzle that may be offset from the first nozzle angularly and/or laterally with respect to the removal path.
