Abstract

An optical fiber cable has a core with a bore which loosely contains optical fibers and includes a single strength member unit preferably embedded in an outer jacket which surrounds the core. The single strength member unit 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 unit, which is at least one 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.
