Abstract
An optical fiber connection structure includes: a multi-core fiber; a plurality of single-core fibers; a first lens having a focal length of f1 (mm); and a second lens having a focal length of f2 (mm). A core pitch of the multi-core fiber is P1 (μm), a mode field diameter on the first end face of each core is MFD1 (μm), a core pitch of multiple single-core fibers is P2 (μm), a mode field diameter of a light beam on the second end face of each core is MFD2 (μm), and the following formulas are satisfied.(1/2)×0.9≤1/2≤(1/2)×1.1, and(1/2)×0.9≤1/2≤(1/2)×1.1
