COATED OPTICAL FIBER |
摘要 |
Provided is a coated optical fiber excellent in both characteristics of the microbending loss resistance and the low-temperature characteristic. The coated optical fiber 1 comprises an optical fiber 10 that has a cladding layer composed of glass formed on an outer periphery of a glass core, a primary coating layer 20 that coats an outer periphery of the optical fiber 10, and a secondary coating layer 30 that coats an outer periphery of the primary coating layer 20, wherein the primary coating layer 20 has a Young's modulus of 1.2 MPa or less, the secondary coating layer 30 has a Young's modulus of 700 MPa or more, and the primary coating layer 20 contains tin in a content of 70 ppm or less. |
