Communications transmission media

A communications transmission medium, which comprises:

• at least one conductor which is enclosed with a plastic material;
• a jacket which comprises a plastic material and which encloses but does not bond to the plastic material which encloses said at least one conductor, said at least one conductor being adjacent to a longitudinal axis of the jacket which passes through a geometric center of each cross section of the jacket which is transverse to the longitudinal axis, and wherein each cross section is defined by a width and a height with an axis which spans each jacket cross section extending along said width and through the geometric center of the cross section, the height of end portions of the cross section being greater than the height of a center portion which connects the end portions to provide a longitudinally extending trough in said jacket which upon the application of cutting forces thereto facilitates the accessing of the conductor which becomes separated from the jacket because of the non-affinity of plastic material which encloses the conductor and of the plastic material comprising the jacket;
• and
• two non-metallic strength members each of which comprises a plurality of filaments that are gathered together and each of which is impregnated with a plastic material that causes it to be coupled to said jacket, each of said strength members being disposed between the at least one conductor and an outer surface of said jacket and aligned with one of said end portions of said jacket such that the strength members and the longitudinal axis which is interposed therebetween are aligned and wherein each strength member passes through each cross section along the axis which spans the cross section.
