Abstract
A process for producing an optical fiber including a glass fiber, a primary resin coating layer which covers the periphery of the glass fiber, and a secondary resin coating layer which covers the periphery of the primary resin coating layer, wherein the primary resin coating layer is formed by curing a curable resin composition which includes one or more oligomers, one or more monomers, and a reaction initiator, the curable resin composition containing a one-end-capped oligomer in an amount of 30% by mass or larger based on all the oligomers. The optical fiber produced by this production process does not deteriorate in low-temperature transmission loss, because the primary resin coating layer is inhibited from generating voids even when having a low Young's modulus.
