An optical fiber cable has a core with a bore which loosely contains optical fibers and includes a single strength member embedded in an outer jacket which surrounds the core. The strength member allows for relative ease of bending of the cable in directions other than the bending directions in the plane of minimum bending energy for the cable, such as bending in the plane of maximum bending energy (MAX-BP) for the cable, and provides that the neutral surface associated with bending of the cable in the MAX-BP is outside the bore core and within the outer jacket. The single strength member furthermore provides tensile strength and antibuckling properties to the cable during storage and in expected installations, including an aerial installation. The outer jacket is releasably coupled to the core to provide ease of access to the optical fibers contained within the core bore.
Câble optique muni d'un cour dont l'âme contient des fibres optiques lâches. Le câble comprend un renfort unique intégré à une gaine extérieure entourant le cour. Le renfort permet de courber facilement le câble dans des directions autres que celles exigeant le minimum de force de courbure, par exemple, dans la direction exigeant le maximum de force de courbure (MAX-BP). Grâce au renfort, la surface neutre associée à la courbure du câble dans la direction exigeant le maximum de force de courbure est située entre l'âme du cour et la gaine extérieure. De plus, le renfort unique résiste à la traction et donne aux câbles des propriétés antiflambage pendant l'entreposage et dans des installations inhabituelles, y compris des installations aériennes. La gaine extérieure est amovible par rapport au cour, ce qui permet d'accéder facilement aux fibres optiques contenues dans l'âme du câble.
