Abstract
A multi-core fiber of the present invention employs the multi-core fiber mode, which corresponds to the 'uncoupled' operation aspect in which individual cores are used independently for single-mode transmission, to perform space division multiplexing transmission using a multi-core fiber in which multiple single-mode cores are stored in one optical fiber. More specifically, the multi-core fiber of the present invention forms an uncoupled multi-core fiber that makes individual cores correspond to single-mode, independent transmission channels.
