ABSTRACT:
A protective sheath for use over a buried fibre optic cable wherein a plurality of spikes extend radially outward from an outer jacket which completely encircles and covers the fibre optic cable bundle which is surrounded by an inner jacket. The inner jacket, outer jacket and spikes are fabricated of a plastic composite material produced by polymerization which can be molded, extruded or cast into a suitable spiked shape. The cable is thereby protected from chewing or gnawing rodents that may be burrowing in the vicinity and would be discouraged from attacking the fibre optic cable even from underneath.
