Kyocera has achieved the world’s fastest speed of 5.2 Gbps for short-distance optical wireless communication in underwater environments.
This technology enables real-time transmission of large volumes of data for marine exploration and underwater robot operations, spurring the development of next-generation marine ICT infrastructure.
Kyocera will exhibit its “Ultra-High-Speed ​​Underwater Optical Wireless Communication Technology” at CES 2026, the world’s largest innovation trade show, to be held in Las Vegas, USA.
Kyocera has achieved stable, high-capacity underwater transmission by applying its proprietary communication specifications, based on a high-speed communication method specifically tailored for underwater environments, to underwater optical wireless communication. By applying its proprietary communication specifications, Kyocera has developed an optical front-end circuit with a wide bandwidth exceeding 1 GHz, taking full advantage of the bandwidth characteristics of optical semiconductor components.
This technology enables the transmission of more information within the same period of time, achieving data transfer speeds approximately 2.5 times faster than conventional underwater optical wireless communication.
