  • Air blown fiber (ABF) cable with low composite coefficient of thermal expansion
    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.
    Type: Grant
    Filed: February 8, 2005
    Date of Patent: November 22, 2005
    Assignee: Sumitomo Electric Lightwave Corp.

  • Air blown fiber (ABF) tube cable with central innerduct
    Patent number: 6101304
    Abstract: A fiber optic cable assembly with enhanced flexibility and reduced installation cost in contrast to conventional multiple duct systems. The fiber optic cable assembly comprises a central innerduct adapted to provide a pathway for installing conventional cable by pulling of the cable therethrough. A plurality of air blown fiber (ABF) tubes are positioned around the circumference of the central innerduct for installing air blown optical fiber bundles therethrough, and a plurality of strength elements are provided around the circumference of the central innerduct and interposed among the plurality of air blown fiber (ABF) tubes. A layer of water-blocking material is provided between an outer jacket and the air blown fiber (ABF) tubes and strength members.
