摘要： A multicore fiber includes cores located at vertexes of a polygonal ring and a cladding including sub medium regions and covering the cores. A refractive index of the cladding is lower than a refractive index of the cores and higher than a refractive index of the sub medium regions. The sub medium regions are arranged at positions to reduce a crosstalk between adjacent cores of the cores.
