Oki Electric Industry Company, Limited <6703> rebounded sharply after announcing on May 26 successful demonstration results for next-generation optical networks using hollow-core optical fiber. The company achieved the world's first bidirectional transmission over a single fiber using broadband wavelength-division multiplexed signals in the 1.26-1.58 micrometer range. As communication traffic surges with the spread of generative AI, the technology aims to enable low-latency, energy-efficient optical networks. It targets "IOWN," a next-generation communications infrastructure concept led by NTT, Inc. <9432>, and "100G-PON," an optical access system aiming for high-speed, high-capacity communications at 100 gigabits per second. Oki Electric conducted the demonstration jointly with Keio University and Litera Japan, a subsidiary of Furukawa Electric Co., Ltd. <5801>.
