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.

摘要： An optical fiber that permits, even when the cladding outer diameter thereof is smaller than 125 μm, an eased splicing with other optical fiber using a general-purpose ferrule, is provided. The optical fiber comprises: a first optical fiber having a first core and a first cladding having a cladding outer diameter smaller than 125 μm, wherein the first cladding has a plurality of air holes that extend longitudinally along the axis of the first core; a second optical fiber having a second core to be spliced to the first core, and a second cladding having a cladding outer diameter larger than the outer diameter of the first cladding, wherein the second cladding is to be spliced to the first cladding; and a fusion splice formed between the end of the first optical fiber and the end of the second optical fiber by fusion.
