NEC Corporation (NEC; TSE: 6701) and NTT Corporation (NTT) announced that they have successfully conducted a first-of-its-kind transoceanic-class 7,280km transmission experiment using a coupled 12-core multicore fiber (*1), which consists of 12 optical signal transmission paths in a standard outer diameter optical fiber (0.125 mm).
This achievement is expected to be a next-generation transmission infrastructure technology that will contribute to the realization of large-capacity optical networks, including future optical submarine cables.
