Disaster Prevention and Security Technologies Contributing to Safe and Secure Networks

摘要

To protect communications networks from large-scale earthquakes, we are conducting research and development of earthquake-proof technology for underground communications facilities and of seismic evaluation methods. We are also deploying optical fiber sensing technology, which can measure the distortion or deformation of structures, in business applications outside NTT to allow precautions to be taken against possible accidents. This article introduces disaster prevention and security technologies for supporting infrastructure equipment in communication networks.
