Abstract
A coated optical fiber comprising an optical fiber for transmitting information having coated thereon a ring-opened (co)polymer of a norbornene derivative having a polar group. Due to the excellent moldability of the polymer, the coated optical fiber can be produced with high productivity. Even when the coated optical fiber is produced at high speeds, the molding strain on the coating is small, and the coated optical fiber has a reduced heat shrinkage.
