ABSTRACT:
A process for producing an optical fiber is disclosed. The process comprises forming a primary coating layer on a glass fiber, forming a secondary coating layer comprising a polyamide resin or polyester elastomer composition containing a polyfunctional monomer as a crosslinking agent, and crosslinking the secondary coating layer by irradiation with electron rays having a maximum transmittance thickness smaller than the total thickness of the primary and secondary coating layers. The resulting optical fiber has excellent heat resistance without causing optical transmission loss.
