Abstract
A thermoplastic resin coated optical fiber having an outer diameter of 0.9 mm is formed by providing a coating layer around a reinforcing resin coated optical fiber having an outer diameter of 0.25 mm, and has a flexural rigidity of 5.5 to 7.5 N·mm . The coating layer comprises a thermoplastic resin having a bending elastic modulus of 200 to 350 MPa and the thermoplastic resin is a polyester elastomer. When optical fiber cords are connected to each other or when an optical fiber is exposed to low temperatures, loss is prevented from increasing and superior transmission characteristics are exhibited.
