	att_abstract={{In this paper, the concept of supermode is introduced for long-distance optical transmission systems. The supermode uses the strong crosstalk between the cores of a multi-core fiber. The strong coupling is obtained by a coupled multi-core fiber in which the core to core distance is much shorter than the conventional multi-core fiber. The use of supermodes leads to a larger mode effective area and higher mode density than conventional multi-core fiber. The simulation results showed lower modal dependent loss, mode coupling and differential modal group delay than step-index few-mode fiber. These properties make the new coupled multi-core fiber design a good candidate for both spatial division multiplexing and single-mode operation}},
