  • Publication number: 20170045700
    Abstract: A device for rearranging optical fibers has a proximal and distal ends. The ends have openings therein to allow optical fibers to pass therethrough. The openings in the distal end have a width that is less than twice the optical fiber's diameter. Dividers separate the distal end openings and have a projection that narrows the distal openings to prevent the optical fibers from accidentally moving out of the openings. A lid is also provided to assist with organization and compression of the optical fibers.

  • Patent number: 8161721
    Abstract: A cable-stranding apparatus for performing SZ-stranding of strand elements about at least one core member is disclosed. A first stationary guide member individually guides the strand elements in a spaced apart configuration and centrally passes the at least one core member. At least one hollow-shaft motor is arranged downstream of the stationary guide member. A rotating guide member is disposed in the hollow shaft and rotates with the hollow shaft according to a rotation relationship. The rotation relationship controls the rotational speed and direction of the rotating guide member to SZ-strand the strand elements about the at least one core member to form an SZ-stranded assembly. Embodiments of cable-stranding apparatus having multiple hollow-shaft motors and respective multiple rotating guide members are also disclosed.

  • Patent number: 7627217
    Abstract: Fiber optic cables are disclosed that have a toning lobe that allows the conductive wire to migrate toward the main cable body while still allowing adequate separation performance of the toning lobe. More specifically, the fiber optic cable includes a main cable body having at least one optical waveguide and a toning lobe. The toning lobe is connected to the main cable body by a web that frangible. In one embodiment, the toning lobe and the web have a generally tear drop shape. The web includes a neck portion adjacent to the main cable body and a web body, wherein the web body generally increases in thickness towards the toning lobe. The shape of the toning lobe allows a conductive wire of the toning lobe to migrate from a center of the toning lobe toward the main cable body while still providing adequate separation performance of the toning lobe.

  • Patent number: 7142752
    Abstract: A buffered optical waveguide includes an optical waveguide having a core, a cladding, and at least one coating and a buffer layer. The buffer layer being disposed around the optical waveguide for protecting the same so that the coupling/adhesion of the buffer layer is reduced. In one embodiment, at least one coating on the optical waveguides has an undulating profile for reducing contact area of the optical waveguide, thereby reducing coupling/adhesion of the buffer layer thereto. In another embodiment, the buffer layer has an internal profile with at least one recessed portion that extends along a longitudinal length of the buffer layer for reducing the contact area of the buffer layer for reducing coupling adhesion thereto. In preferred embodiments, the buffered optical waveguide is about 900 microns or smaller.
