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_GΔβ is 6.1 ([GPa−1·μm−2.5/rad8]·10−12) or less when represented by FμBL_GΔβ=FμBL_G×FμBL_Δβ, where FμBL_G is geometry microbend loss characteristic and FμBL_Δβ is optical microbend loss characteristic.
