摘要： An optical fiber array having a plurality of intermittent weakened portions allows subunit or groups of the fibers in the optical fiber array to be accessed without the need for special tools and a method for manufacturing the same are provided. In one embodiment, the optical fiber array includes at least two subunits, each of the subunits having a respective subunit matrix, and the optical fiber array also includes a common matrix having a plurality of intermittent weakened portions. In another embodiment, the plurality of intermittent weakened portions of the optical fiber array are formed by a common matrix having two different thickness profiles adjacent along respective portions of a subunit interface.

摘要： A fiber optic ribbon having one or more fracture locations for influencing the separation of the same at predetermined locations is disclosed. The fiber optic ribbon includes a plurality of optical fibers held together by a primary matrix. The primary matrix includes a first fracture region for splitting the optical fiber ribbon into a plurality of optical fiber subsets. The first fracture region is defined by a first group of preferential tear features that protrude beyond a major primary matrix plane, thereby forming a first local minimum thickness between adjacent optical fibers. The first local minimum thickness enables splitting of the fiber optic ribbon into subsets at the first local minimum thickness, thereby allowing the craft to separate the fiber optic ribbon into subsets without using tools. Additionally, fiber optic ribbons of the invention may include a secondary matrix.

摘要： In optic cable there is provided a ripcord which lies partly within the sheath and partly outside the sheath by extending between overlapped edges of the sheath. Parts of the ripcord outside the sheath and spaced along the cable and are accessible by removal of directly overlying regions of jacket. No cutting of the sheath is required to access the ripcord which, however, after access may be used for ripping along the sheath.
