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, which consists of 12 optical signal transmission paths in a. 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, which consists of 12 optical signal transmission paths in a. Conventional optical fiber has a core that goes through the center for transmitting light. Multicore optical fiber, on the other hand, has multiple cores passing through a single optical fiber, which drastically increases traffic while maintaining the diameter of the optical fiber. By using a connected 12-core multicore fiber - a standard outer diameter optical fiber (0.
