MEASURING METHOD AND MEASURING DEVICE OF OPTICAL CHARACTERISTICS OF MULTI-CORE OPTICAL FIBER

원문 (중국어)

This method for measuring the optical characteristics of a multi-core optical fiber (MCF) includes: connecting, to a first end face of MCF, a first optical fiber having the same diameter as MCF and connected to a light source, and connecting, to a second end face of MCF, a second optical fiber having the same diameter as MCF and connected to a measuring instrument; and irradiating the first end face with measurement light emitted from the light source via the first optical fiber, and measuring light emitted from the second end face with the measuring instrument via the second optical fiber. The connecting includes aligning the rotational angle of the first end face, aligning the rotational angle of a first connection end face, abutting and connecting the aligned first end face and first connection end face, and abutting and connecting the second end face and a second connection end face.
