Researchers at NTT, Fujikura, and Hokkaido University have demonstrated the world’s highest density optical fiber.
The optical fiber has a diameter of less than 250 µm and contains 19 optical paths (cores) that can support six kinds of optical signals (modes). It provides 114 (= 6 modes × 19 cores) spatially multiplexed communication paths (channels) in one optical fiber.
The researchers calculate that the ultra-large capacity optical fiber that can handle a Peta- to Exa-bit transmission capacity.
The work was partially based on work commissioned by the National Institute of Information and Communications Technology (NICT).
