Abstract:

There is provided a cable construction which resists attack by mammals, fowl or fish. The cable construction consists of a core containing at least one optical fiber about which there is an organic cushion layer, preferably polymeric in nature. About the cushion layer there are a pair of counter-helically wound resin-impregnated inorganic fibers to provide tensile and hoop strength. About the pair of counter-helically wound inorganic fibers there is provided one or more layer(s) of resin-impregnated inorganic fibers helically-wound to an angle greater than 60. degree. , and preferably approaching 90. degree. These fibers when bitten provide needle-like projections which irritate the mammal, e. g. , rodent, fowl or fish and discourage any attempt to continue to attack the cable. The cable is normally provided with an outer casing of a thermoplastic polymer for handling purposes.
