An interdisciplinary team of researchers led by the CONNECT Research Center, based at Trinity College Dublin, is developing sensors to detect and ultimately analyze tiny changes in light as it travels through existing underground and seacoast fiber-optic cables (see video). If 5G is the neural conduction of the digital age and AI the super brain, fiber sensing serves as the quietly growing peripheral nerves. In 2023, a group from California Institute of Technology, collaborating with Google, achieved the world's first commercial submarine cable-based second-level. A new Fiber Broadband Association report explores how Distributed Fiber Optic Sensing (DFOS) can help operators improve network resilience, enable AI-driven monitoring, and unlock new revenue streams. By combining this sensing technology with AI analysis, existing fiber optic infrastructure, such as that of telecommunications companies, can be used as sensors. This is NEC's proprietary. Distributed fiber optic sensing turns standard optical fibers into thousands of sensors for real-time environmental awareness, infrastructure monitoring and intelligent network optimization — effectively creating an early-warning system that enables operators to prevent failures and improve network.
