Abstract: The invention relates to optical fiber cables and, more specifically, to an optical fiber cable especially suited for blown installation or pushing installation in microducts of small diameter. An exemplary microcable for installation in small microducts has an outer sheath as buffer tube that holds a plurality of optical fibers without a layer of strength elements stranded around the outer sheath, which is made of one single thermoplastic material.

Abstract: The present invention relates to loose tube optical waveguide fiber cable which is optimized for easy and fast installation as plenum cable, such as in customer premises for FTTH (fiber to the home) applications. One of the objects of the present invention is to provide a loose tube optical waveguide fiber cable which is suitable for fixed in-house cabling at extremely low-cost for a large-scale installation of FTTH.

Abstract: Disclosed is a central loose tube fiber optic microcable that includes a protective sheath enclosing a plurality of optical fibers. The microcable protective sheath is composed of two layers of different synthetic materials, namely an inner layer having an elasticity modulus of about 1500-3000 MPa and an outer layer having an elasticity modulus of about 600-1200 MPa.

Abstract: The present invention relates to a loose tube optical waveguide fiber cable that is suitable for riser or plenum applications. The cable includes a protective tube that loosely surrounds two or more optical waveguides inside the hollow cavity defined by the tube. The protective tube has an inner surface and an outer surface and is a dry structure. Accordingly, the protective tube does not contain any gel-like compounds or other materials around the optical fibers positioned inside the protective tube. Strengthening members are disposed between the inner surface of the protective tube and the outer surface of the protective tube. The strengthening members are configured as embedded or layered strengthening elements and are disposed longitudinally along the length of the cable.

Abstract: A cable bolt comprises a cable with a tubular yielding fixture at one of its ends. The pull-off load of such yielding fixture can be adjusted to a desired value. This is achieved by unwinding one end of the cable and inserting a slug over the kingwire. Then, the peripheral wires are wound again over the kingwire forming a bulge in the cable where the slug is located. The yielding fixture is then slid on the cable and forced over the bulged portion of the cable, while measuring the load required to achieve this operation, which also becomes the pull-off load of the yielding fixture. Finally, any part of the cable protruding from the fixture is cut-off to form the cable bolt with the desired yielding fixture at its end.
