Abstract
An optical fiber having reduced residual stress discontinuity is disclosed. The optical fiber includes a core which is an optical transmission medium and a clad for surrounding the core. The residual stress discontinuity at an interface between the core and the clad is 20.0 MPa or less, which is represented by an absolute value of a difference between a minimum axial stress at (r/a)=0.8-1.1 and a maximum axial stress at (r/a)=1.0-1.2, wherein a is the radius of the core and r is a radius measured from the center of the core.
