Abstract
A fiber optic cable and method for making same wherein the cable includes at least one elongate fiber optic element, a nonmetallic tubular shield disposed substantially coaxially along the length of the fiber optic element, and a nonmetallic braided strength member disposed coaxially along the length of the tubular shield layer in tight fitting relation thereon. The braided strength member is selected to have greater tensile strength and lower elongation per unit length than the fiber optic element so that any tensile load applied to the cable is taken substantially by the braided strength member so as to prevent undesirable elongation and damage to the fiber optic element. In a preferred embodiment, an abrasion resistant layer is disposed between the braided strength member and the tubular shield, and a protective jacket is formed over the braided strength member. In another embodiment, a second braided strength member is formed coaxially over the first jacket layer and a second outer protective jacket is formed coaxially over the outer braided strength member.
