  • Fiber optic cable with ripcord
    Patent number: 6088499
    Abstract: A fiber optic cable (10) includes a cable core (20) and a sheath section (40). Interstitial assemblies (30) are disposed between cable core (20) and sheath section (40, at least one of the interstitial assemblies (30) includes a ripcord (38). Ripcord (38) is operative, upon application of a sufficient outwardly directed pulling force, to rip a cable core binder (26) stranded around buffer tubes (23), water swellable tape (27), and a binder (29) stranded around tape (27). A craftsman need not use a cutting tool to cut binders (26,29) and/or tape (27) which saves time and avoids potential injury to the craftsman and inadvertent damage to buffer tubes or other cable components.
