Abstract
Abstract A cable is disclosed having two optical fibers spaced apart by portions of two strands of fibrous material laid with the optical fibers that is made by laying the two optical fibers and two strands of fibers with the serve angle of the strands of fibrous material being less than the serve angle of the optical fibers and at 90° thereto to cause the optical fibers to be held apart by portions of the fibers making up the strands. Tape is wrapped around the twisted optical fibers and strands of fibrous material after which the laid optical fibers and the fiber strands are enclosed in an outer jacket.
