Abstract

ABSTRACT OF THE DISCLOSURE

The optical fiber cable has a plurality of centrally located optical fibers. Carrying the optical fibers is a gel-filled plastic buffer tube. A
plurality of radial strength yarn threads extend along the outside of the buffer tube in a contra-helical pattern. In the armored cable embodiment, a strength and protective member in the form of a corrugated steel armor layer may be provided for additional protection against possible rodent damage. The armor is usually coated with a thin layer of plastic material in the form of a water blockable flooding compound. A ripcord is provided to assist in removal of the armor. A final polyethylene outer jacket is provided for additional cable protection. Embedded within the outer jacket is a pair of diametrically opposed, longitudinally extending strength members.
