<p>At least two layers (2,3) of coating materials are applied to the periphery of a silica-based optical fiber (1) to fabricate a coated optical fiber. This coated optical fiber has durability against a proof test of 1.38 GPa or more through the entire length thereof and also has 1.4 N or less of a coating strip force required for removing coating from the silica-based optical fiber. Thereby, when a proof test applying an elongation of 2% or more is conducted, the coating can be prevented from delaminating from the optical fiber and workability in removing the coating also becomes excellent. The coated optical fiber preferably makes a coated optical fiber for components. <IMAGE></p> |
