Abstract
Official abstract text for this publication.
A multi-core fiber (23) connects an optical transmitter device (10) and an optical receiver device (30) to each other. The multi-core fiber (23) includes cores each having a wavelength dispersion characteristic different from a wavelength dispersion characteristic of another adjacent core of the cores. In an optical transport system (100), the optical transmitter device (10) and the optical receiver device (30) are connected in series by the plurality of multi-core fibers (23).

1 . A multi-core fiber configured for connecting optical transport devices to each other, the multi-core fiber comprising: cores each having a wavelength dispersion characteristic different from a wavelength dispersion characteristic of another adjacent core of the cores. 2 . An optical transport system including optical transport devices connected in series by a plurality of multi-core fibers, wherein each multi-core fiber includes cores each having a wavelength dispersion characteristic different from a wavelength dispersion characteristic of another adjacent core of the cores; and when an optical signal passes through a first core of a first multi-core fiber of the plurality of multi-core fibers and a second core of a second multi-core fiber of the plurality of multi-core fibers, a wavelength dispersion characteristic of the first core is different from a wavelength dispersion characteristic of the second core. 3 . The optical transport system according to claim 2 , wherein the cores of each multi-core fiber are regularly arranged in a concentric circle, and the second multi-core fiber is connected to the first multi-core fiber in a state in which the second multi-core fiber having the same core arrangement as the first multi-core fiber is rotated relative to the first multi-core fiber. 4 . The optical transport system according to claim 2 , wherein the wavelength dispersion characteristic of the second core is opposite to the wavelength dispersion characteristic of the first core. 5 . An optical transport method implemented by an optical transport system including optical transport devices connected in series by a plurality of multi-core fibers, wherein each multi-core fiber includes cores each having a wavelength dispersion characteristic different from a wavelength dispersion characteristic of another adjacent core of the cores; and when an optical signal passes through a first core of a first multi-core fiber of the plurality of multi-core fibers and a second core of a second multi-core fiber of the plurality of multi-core fibers, a wavelength dispersion characteristic of the first core is different from a wavelength dispersion characteristic of the second core, the optical transport method comprising: transmitting an optical signal to each core of the first multi-core fiber by using a first optical transport device; and receiving an optical signal from each core of the second multi-core fiber by using a second optical transport device.
