1. An ADSS (All-Dielectric Self-Supporting) optical cable comprising:
- a central tensile member extended in a longitudinal direction;
at least one optical fiber for transmitting an optical signal;
at least one tubular buffer receiving the at least one optical fiber therein and arranged around the central tensile member adjacently, the tubular buffer being twisted on the center of the central tensile member;
an inner sheath extended in the longitudinal direction with surrounding the at least one tubular buffer;
an outer tensile member extended in the longitudinal direction with surrounding the inner sheath; and
an outer sheath extended in the longitudinal direction with surrounding the outer tensile member, wherein the outer tensile member includes;
a plurality of tensile wires extended in the longitudinal direction in parallel without intentional twisting on the central tensile member; and
an adhesive resin for connecting the tensile wires adjacent to each other.

Abstract
A method for producing an optical fiber cable which improves stability by attaching an Aramid yarn near the core in parallel to an axial direction of the optical cable and solves structural problems of the cable by soaking an Aramid yarn into an epoxy resin is disclosed. This optical cable producing method uses a tensile material for improvement of tensile property, and includes the steps of soaking the tensile material into an epoxy resin, and attaching the tensile material to the optical cable in parallel to the axial direction of the optical cable.
