Patent ID: 7113680

Claim:
A fiber optic breakout cable comprising a plurality of cable units disposed within an outer jacket, wherein each of the plurality of cable units comprises: at least one bundle, the at least one bundle comprising a plurality of non-tight buffered optical fibers and a binder element for maintaining the plurality of non-tight buffered optical fibers in the at least one bundle; a separation layer contacting at least some of the plurality of non-tight buffered optical fibers, wherein the separation layer is formed from a plurality of tensile yarns for providing a tensile strength characteristic for the cable unit; and a cable unit jacket, the cable unit jacket surrounding the at least one bundle and the separation layer and contacting a portion of the separation layer thereby forming the respective cable unit, wherein the separation layer inhibits adhesion between the at least one bundle and the cable unit jacket and wherein the fiber optic breakout cable excludes a grease or a gel composition being in contact with the at least one bundle for filling interstices of the cable unit thereby blocking water from flowing through the cable.
