Optical Fiber Communication Still is the Major Transmission Technology

ITU Telecom, which opens once every 4 years, is the largest exhibition in the world. Telecom99 is the largest one of ITU Telecom. This report introduces the development status of optical fiber communications technologies recently base on visited Telecom99. The conclusion is that optical fiber communication still is the major transmission technology. This paper introduces the development of optical fiber communications in core network from several areas such as equipment and systems, optical fiber and cable, optical devices, test and measurement instrument, engineering installation and others. Optical access technologies are out of the scope, it will be included in another special report.
