ABSTRACT:
A method for manufacturing a steel wire material for reinforcing an optical fiber is proposed. In this method, a steel wire is firstly subjected to a chemical conversion treatment. The wire is then drawn with a reduction of area of 30% or more. As a result, a coating capable of effectively restraining the production of hydrogen is formed on the surface of the wire.
