Long-distance optical cable capacity

Sumitomo Electric Industries, Ltd. and the National Institute of Information and Communications Technology (NICT; Head Office: Koganei-shi, Tokyo; President: Hideyuki Tokuda) have set a new world record* for long-distance high-capacity transmission in optical fiber communications . Sumitomo Electric Industries, Ltd. 5km by applying large-scale MIMO 1 signal processing technology in a terrestrial field environment in which a 12-core fiber with the same diameter as existing. Once 5G, autonomous driving, and metaverse become commonplace, the capacity of current optical fiber networks is expected to reach its limit. Conventional optical fiber has a core that goes through the. This is a major step to realize future long-distance, large-capacity optical communication systems. [pdf]
