Abstract
An optical fiber connection structure reducing MPI is provided. An intervening optical fiber 30 having a normalized frequency less than 2.405 and a length greater than or equal to 2 mm and less than or equal to 30 mm is interposed between a single-mode fiber 10a and a second single-mode fiber 20, and the second single-mode fiber 20 and the intervening optical fiber 30 are fused together. While transmission light is input through the first single-mode fiber 10a to the second single-mode fiber 20, a higher order mode is not generated in the second single-mode fiber 20.
