Abstract
A characteristic-measuring apparatus for a multi-core fiber includes: a coupling device that couples, at a first end of the multi-core fiber, light to a plurality of cores in the multi-core fiber; an imaging device that takes an image, at a second end of the multi-core fiber, of emission light emitted from the plurality of cores, where the plurality of cores are imaged at the same time; and a calculating device that determines a characteristic of the multi-core fiber based on images obtained by the imaging device.
