  • Patent number: 3955878
    Abstract: A fiber optic transmission line suitable for use in a submarine cable wherein one or more helically formed optical fibers are positioned lengthwise within a flexible tubular member containing a semi-fluid gelantinous substance. Due to the helical form of the fibers, the fibers are not stressed even when the line is subjected to axial load. The gelantinous substance retains the fibers in their helical form and prevents abrasion of the fibers. A method for forming such a fiber optic transmission line is also disclosed.
