Abstract:
    A multi-core optical fiber with improved dimensional accuracy is produced by a method comprising inserting at least two core glass rods in bores formed in a cladding glass rod having a refractive index lower than that of the core glass rods to be inserted, heating a composite of the cladding glass rod and the core glass rods to integrate them together, and drawing the integrated composite to fabricate a multi-core optical fiber. The drawing may be carried out simultaneously with the integration step.
