Optical fiber equipped with cladding and method of manufacturing the same

摘要

A coated optical fiber comprising a drawn glass fiber, and a primary coating and a secondary coating which are formed by photo-curing primary and secondary coating resins simultaneously applied to an outer periphery of the glass fiber, wherein an adhesion force S (g/cm) at an interface between the primary coating resin after curing and the glass fiber is at least 1/13 ((g/cm)/ DEG C) with respect to a glass transition temperature Tg ( DEG C) of the secondary coating resin after curing.
