A research team from NTT in Japan has developed an MCF design with 12 core paths--a first. Single-mode optical fibers are quickly approaching capacity limits on today's networks. Multimode fibers may seem an obvious solution, but suffer from dispersion and limitations. Tokyo, Japan, March 21, 2024 – NEC Corporation (NEC; TSE: 6701) and NTT Corporation (NTT) today 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. On March 21, NEC and NTT announced that they have successfully conducted the world's first transoceanic long-distance transmission experiment over a distance of 7280 km using a 12-core coupled multicore fiber with 12 optical signal transmission paths in a standard outer diameter (0.
