Maintenance and Management Technology for Safe, Secure, and Economical Operation of Telecommunication Infrastructure Facilities

摘要

The conduits, manholes, tunnels, and other telecommunication infrastructure facilities that support optical access networks are aging rapidly, just as roads, bridges, and other elements of the social infrastructure are. The ability of these facilities to withstand large-scale earthquakes is also a major concern. These Feature Articles describe the latest technical trends in facilities management, inspection and diagnosis, repair and reinforcement, and technology for making facilities resistant to earthquake damage as part of efforts to achieve safe and secure telecommunication infrastructure facilities as well as economical maintenance.
