Impact Goals of Research and Development Technology on the Business Strategy of NTT’s Fiber-to-the-Home Deployment

摘要

Huge investment is needed for introducing a fiber-to-the-home system, so research and development strategy is very important. Requirements for fiber-to-the-home systems have been increased because communication systems have been recognized as one of the lifelines along with water, electricity, and gas. Furthermore, low energy consumption and recyclable eco-friendliness are required for products. NTT has been challenged to reduce capital expenditure, reduce operational expen-diture, and create new applications for expanding the number of fiber-to-the-home subscribers from the viewpoint of a technological approach, including access infra-structure, fiber, transmission, and wireless technologies.Due to continuous and strategic technological development, the number of NTT’s fiber-to-the-home subscribers is now over 17 million.
