Abstract
An optical transmission line including a portion formed by fusion-splicing optical fibers having structures different from each other; wherein, in the optical fibers having structures different from each other, a first optical fiber 1 has a mode field diameter smaller than that of a second optical fiber 2 fusion-spliced thereto; and wherein the first optical fiber 1 has an average viscosity from a center to an outermost layer greater than that of the second optical fiber from a center to an outermost layer.
