Claim Text:
1. A multicore fiber comprising: a plurality of cores; and a cladding enclosing the plurality of the cores, wherein the plurality of the cores has two cores or greater forming a first plurality of cores linearly arranged to form a first row on one side based on a plane passed through a center axis of the cladding, and three cores or greater forming a second plurality of cores arranged in parallel with the first plurality of the cores to form a second row on other side based on the plane, and one of the cores configuring the first plurality of the cores and one of the cores configuring the second plurality of the cores are disposed on a line orthogonal to the plane, wherein all of the first plurality of cores and the second plurality of cores have substantially a same relative refractive index difference to the cladding, wherein the number of cores adjacent to any given core at an almost same distance is not more than two, wherein a first core-to-core distance between a first pair of adjacent cores in the first row is different from a second core-to-core distance between a second pair of adjacent cores in the second row, wherein all of the first plurality of cores and the second plurality of cores are separated and optically uncoupled from one another, wherein an n
