Abstract
The present invention relates to a multimode optical fiber having a structure for stably reducing eccentricity relative to an insert hole of a connector ferrule to be mounted at an end thereof, wherein a fiber outer diameter of the multimode optical fiber along its longitudinal direction varies periodically in a range of ±0.5 μm with respect to a target fiber outer diameter.
Claims3
A multimode optical fiber having a glass portion composed of silica glass, the glass portion comprising:
- a core extending along a central axis and having an alpha-power index profile;
- and
- a cladding surrounding an outer peripheral surface of the core,
- wherein an outer diameter of the glass portion along a longitudinal direction thereof varies periodically in a range of ±0.5 μm with respect to a target outer diameter of the glass portion.

A multimode optical fiber having a glass portion composed of silica glass, the glass portion comprising:
- a core extending along a central axis and having an alpha-power index profile;
- and
- a cladding surrounding an outer peripheral surface of the core,
- wherein a maximum variation of an outer diameter of the glass portion along a longitudinal direction thereof is in a range of ±0.5 μm with respect to a target outer diameter of the glass portion,
- wherein the glass portion comprises a first region as a region having an outer diameter larger than the target outer diameter and taking a maximum of the outer diameter at some position, and a second region as a region having an outer diameter smaller than the target outer diameter and taking a minimum of the outer diameter at some position, the first and second regions being alternately arranged along the longitudinal direction.
