  NTT reinforces R&D toward the realization of a next-generation IP network that maintains the properties of both the Internet and telephone networks as a shared infrastructure with high quality, security and reliability by integrating long-accumulated telephone networking technology and leading-edge IP technology. In the field of optical-related technology, NTT boasts the world's top-rated technology as represented by the development of optical switches and the "Free Bending Optical Fiber Cord," an optical fiber cord that can be handled much more easily and quickly than conventional ones, facilitating the low cost and rapid execution of installation works. Such R&D results have already led to the realization of highly reliable large-capacity telecommunications, efficiency improvement of works and cost reduction.

• R&D to address social problems
