摘要： A plurality of telecommunications connections are installed in a distribution network by connecting a series of distribution points using a multicore cable comprising a plurality of cores having a common enclosure, some of the cores carrying fiber tubes into which optical fiber may later be introduced, and other cores carrying an electrical power supply. One or more cores may be diverted from a longer cable run to serve a local distribution point by rupturing a web connecting the core to the rest of the cable, thus allowing the remaining cores to be uninterrupted at the point of divergence. An alternative embodiment intended for underground use provides for apertures to be opened in a protective sheath to expose the individual cores required to be diverted to a local distribution point.

摘要： Teachings of the present disclosure relate to a pulling sleeve for pulling a cable through a conduit. The pulling sleeve is mounted over fibers of a fiber optic cable and a plurality of fiber optic connectors associated with the fibers. The pulling sleeve includes an elongated body formed of two mating pieces to include an interior cavity to receive and house the fibers. The two mating pieces may include half-pieces. The elongated body of the pulling sleeve includes a length that extends along a central axis between first and second ends, where the first end of the elongated body includes a pulling eye. Also, the elongated body of the pulling sleeve defines a plurality of axially spaced-apart circumferential notches for enhancing flexibility along its length. The axially spaced-apart circumferential notches enable the elongated body of the pulling sleeve to conform to a curved conduit path.
