Title:

OPTICAL FIBER, METHOD FOR CENTERING OPTICAL FIBER AND CONNECTION STRUCTURE FOR SAME, TAPE CORE WIRE, AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2016/084465

Kind Code:

A1

Abstract:

Provided is a multicore fiber 1 comprising a plurality of cores 5, a cladding 3 sheathing around the cores 5 and having a lower refractive index than the cores 5, and a sheathing resin 7 sheathing the cladding 3. The plurality of cores 5 together serve as a core group 5a. The cores 5 are arranged to have symmetry within the range of the core group 5a. In a cross section taken perpendicular to the lengthwise direction of the multicore fiber 1, the locations of the centers of the cladding 3 and the resin sheath are approximately aligned. On the other hand, in a cross section taken perpendicular to the lengthwise direction of the multicore fiber 1, the location of the center of the multicore fiber and the location of the center of the core group 5a are offset.
