Development of the optical fibre network in China

China is experiencing a very rapid phase of development in the optical fibre network. Recent years saw the completion of many long-distance fibre-optic cable trunks, bringing the total length of China's fibre-optic cable to 70000 km, connecting all the 29 provinces. A fibre-optic cable network with Beijing as the centre has been primarily formed. The successful opening of some 2.4 Gb/s SDH systems in 1995 marked a higher step in the nation's trunk telecommunications technology. To upgrade the basic telecommunications network, the building of the SDH network, CCS No.7 network and monitoring and control network has been accelerated. As a part of CNII (China National Information Infrastructure), a new development of fibre-optic cable network has been planned.
