  • Fiber optic cable construction
    Patent number: 4054365
    Abstract: This specification describes a fiber optic cable in which the delicate glass fibers are supported by carriers which protect the fibers from stresses imposed during the manufacturing process, the installation of the cable and the environmental conditions after installation. Microbending of the fibers is eliminated by having smooth supports and by protecting the fibers from contact with any structure that will stress them. Another feature is the provision of tension elements in the carriers with neutral axes in transverse alignment with the neutral axes of the glass fibers that the carriers support.
