Abstract

An optical fiber includes a glass portion, a primary coating layer, and a secondary coating layer. In the optical fiber, a value of microbend loss characteristic factor FμBL_GO is 2.6 ([GPa−1·μm−10.5·dB/turn]·10−27) or less, when represented by FμBL_GO=FμBL_G×FμBL_O by using geometry microbend loss characteristic FμBL_G and optical microbend loss characteristic FμBL_O.
