Abstract
A process for producing an optical fiber is described, wherein a fiber that has been drawn from a glass preform is coaed with a resin composition curable with heat, ultraviolet rays, or electron beams, and then cured, wherein before the drawn fiber contacts another solid object, the fiber is cooled by being passed through a cooling means filled with a non-reactive liquid material which is the same as said resin composition except that it is free from any compound that catalyzes curing of the resin, selected from among a curing agent, a cross-linking agent, curing catalyst, curing accelerator, sensitizing agent and a reactive diluent, and then the fiber is coated and with said resin composition and cured.
