Abstract
Official abstract text for this publication.
Multi-core fibers are optical fibers each of which has a circular cross section. In each of the multi-core fibers, a plurality of cores are arranged at a prescribed interval, the peripheries thereof are covered by a cladding, and a resin coating is formed on the outer periphery of the cladding. In a cross section of this optical fiber ribbon, said cross section being orthogonal to the length direction, the multi-core fibers are arranged such that the cores of all of the multi-core fibers are all arranged in the same direction. The multi-core fibers are arranged such that central lines of the respective multi-core fibers, said central lines respectively linking three of the cores, all face the thickness direction of the optical fiber ribbon. Furthermore, in the optical fiber ribbon, the arrangement of the cores is substantially constant along the entire length of the optical fiber ribbon in the length direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of producing an optical fiber ribbon including a plurality of optical fibers arranged in parallel, wherein: a form of a cross section of each of the optical fibers taken in a perpendicular direction to a longitudinal direction thereof has an orientation in a rotational direction with the longitudinal direction of the optical fiber as an axis, the method including: a light introducing step which introduces light into a core of each of the optical fi…
