<p>A multi-core optical fiber according to an embodiment of the present invention is provided with a plurality of core parts, a common cladding, and a coating. Particularly, in order to improve a spectral efficiency per unit sectional area, optical properties typified by the number of core parts, a sectional area of the entire multi-core optical fiber, the sum of power coupling coefficients to a core part n from all the other core parts, and a transmission loss, a non-linear refractive index, an effective area, and a chromatic dispersion of the core part n with the largest crosstalk from other core parts are set so as to satisfy a predetermined relation.</p> |
