    摘要: An optical fiber connection structure which reduces MPI in the use of an optical fiber with a bend resistance improved by forming holes in the fiber, and a single-mode fiber which reduces MPI are provided. A second cladding portion of a second single-mode fiber 20 includes holes 28, and thus, the second single-mode fiber 20 has low bending loss. A portion of the second single-mode fiber 20 connected to a first single-mode fiber 10a is made solid by filling corresponding portions of the holes 28 over the length L0, and light in a mode LP11 is significantly attenuated in this portion, thereby reducing MPI.

    摘要: 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.
