Abstract
The optical fiber has an effective area that is greater than or equal to 110 μmand less than or equal to 180 μmat a wavelength of 1550 nm and a cable cut-off wavelength of less than or equal to 1530 nm. An average value of a glass outer diameter in a longitudinal direction is 125±0.5 μm. When σ is a standard deviation of the glass outer diameter in the longitudinal direction, 3σ is greater than or equal to 0.1 μm and less than or equal to 0.5 μm.
