Research is progressing on utilizing the communication optical fiber networks deployed throughout cities not only for data transmission but also as sensors through optical fiber sensing. Various considerations are being made toward its social implementation. This article focuses on Distributed Acoustic Sensing (DAS), which measures vibrations in optical fibers and is attracting significant attention, and describes NTT’s research on improving its performance and exploring practical applications.
