  • Patent number: 6597844
    Abstract: An optical fiber cable comprising a plurality of buffer tubes, binder wrapped around the buffer tubes, a ripcord disposed between the buffer tubes and the binder, and a protective outer jacket covering the buffer tubes. Upon application of a sufficient outwardly directed pulling force, the ripcord rips both the binder and the jacket thereby providing access the buffer tubes and optical fibers therein. The binder is formed of a material which melts or softens when the jacket is formed by an extrusion process so that the binder is thereby incorporated into the jacket. Alternatively, the binder is formed of a material which will adhere to the jacket when the jacket is formed by an extrusion process and is easily torn when the jacket is ripped by the ripcord.
