Title:
OPTICAL CONNECTOR
Document Type and Number:
WIPO Patent Application WO/2024/079959
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical connector with which it is possible to suppress reflection at a connecting part. This optical connector 1 comprises a multi-core fiber 10 having a plurality of cores 11, and a ferrule 20 that includes a through-hole 23 into which one end side of the multi-core fiber 10 is inserted, wherein: an end face 25 of the ferrule 20 overlaps with a spherical plane SS that contacts, on a center axis 23C of the through-hole 23, an inclined plane FS which inclines with respect to a perpendicular plane FP perpendicular to the center axis; an end face 15 on one side of the multi-core fiber 10 inclines to the same side as the side on which the inclined plane FS inclines with respect to the perpendicular plane FP; and when the radius of curvature of the spherical plane SS is defined as B (mm), an eccentricity amount that is the distance to a top position TP protruding most from a line CL going through the center axis 23C and connecting the center line 23C, the spherical plane SS, and edges ED of the end face 25 in a cross-section perpendicular to the inclined plane FS is defined as C (μm), and the distance between the center axis 23C and the center of the core 11 positioned most separated from the center axis 23C when viewed along the center axis 23C is defined as x (μm), the following expression is satisfied.
