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.

Câble à fibres optiques (10) comprenant une âme (20) et une enveloppe (40). Des éléments interstitiels (30) sont placés entre l'âme (20) et l'enveloppe (40) du câble. Au moins un des éléments interstitiels (30) comprend une cordelette d'ouverture (38) qui, sur application d'une force de tirage suffisante dirigée vers l'extérieur, sert à rompre le feuillard (26) de l'âme du câble qui entoure les gaines (23), le ruban (27) gonflant dans l'eau et une bande (29) enroulée autour du ruban (27). Il n'est pas nécessaire d'utiliser un instrument tranchant pour couper le feuillard et la bande (26, 29) et/ou le ruban (27), ce qui permet de gagner du temps, d'éviter à l'ouvrier de se blesser et d'éviter que des dommages accidentels soient causés aux gaines ou à d'autres éléments de câble.
