Home / Sample of 12-core optical fiber cable for long-distance transmission
NEC Corporation and NTT Corporation have announced that they have successfully conducted a first-of-its-kind transoceanic-class 7,280km transmission experiment using a coupled 12-core multicore fibre (*1), which consists of 12 optical signal transmission paths in a. We spoke with the researchers about the details on what purpose and meaning this success has and what technologies were used to achieve this success. As more cores are added to an optical fiber with a standard outer diameter, crosstalk occurs when optical signals leaking from a core.
These crosstalks also prevent the SDM from realizing long haul transmission. Thus, in order to realize future dense SDM (DSDM) systems, multicore fibers with few-mode cores, known as

Doesn''t that significantly increase the distance that the light has to travel? If so, by how much does it slow down the time the light takes to travel through the cable?
