Abstract

A coating is provided for an optical fiber that inhibits abrasion or scraing of the fiber's surface. The coating is obtained by depositing a thin film of non-hydrogenated diamond-like amorphous carbon (a-C) onto the optical fiber using a laser ablation technique employing graphite as a target material.
