  • Patent number: 7653277
    Abstract: An optical fiber cable having a locating element and extending from a distribution enclosure to a premise is provided. The optic fiber cable includes a core having at least one optical fiber transmission medium disposed within a tubular member that has a jacket system disposed thereabout. A longitudinally extending detectable element is provided that does not function as a communications cable and that is detachably connected to said tubular member by the jacket system which is also disposed about the detectable element so as to define a web between the tubular member and the detectable element. The detectable element terminates before at least one of the distribution enclosure or the premise. The web defines a notch between the tubular member and the detectable element which serves as a shear plane to facilitate the propagation of a tear between the tubular member and the detectable element.

  • Patent number: 7313304
    Abstract: The present invention provides a dielectric optical fiber cable which is capable of being remotely detected while buried. Specifically, this invention incorporates a detectable and easily removable locating element which is attached to the optical fiber cable by a web defined by the jacket extending over both the optical fiber cable and the locating element. The web allows for the locating strand to be easily removed once separation of the locating element from the optical fiber cable is initiated. The web is designed to allow the initial tear to propagate into a precise longitudinal tear along a predetermined length of the optical fiber cable.

  • Patent number: 6968106
    Abstract: An air blown fiber tube cable having improved thermal stability in contrast to conventional air blown fiber (ABF) tube cables and within which one or more air blown optical fiber units can be installed. The air blown fiber tube is formed from a cross-linked polyolefin (preferably cross-linked high density polyethylene) comprising at least one non-polymer filler material having a coefficient of thermal expansion less than the coefficient of thermal expansion of said tube.

  • Patent number: 6633709
    Abstract: A water-tight fiber optic ribbon communications cable constructed without the use of gel or grease in the buffer tube(s) thereof. A plurality of water-blocking yarns are provided around at least a portion of the stack of fiber optic ribbons loosely positioned within the buffer tube(s) that possess water swellable characteristics. The swell capacity of the plurality of water blocking yarns exceeds the critical mass of water that could enter the buffer tube(s) by a factor of 2.0 or more. Optionally, superabsorbent powder can be applied between and/or on the fiber optic ribbon stack.
