ABSTRACT:
In a single mode optical fiber formed of a silica-based glass and including a glass part having a central core and a cladding region, the density of non bridging oxygen hole center in the glass part is not higher than 1.0×1014spins/g in terms of the spin density measured by an electron spin resonance method.
