摘要
国内未来高速铁路需要学习借鉴国外高速铁路采用的通信系统。新业务的高速增长和WDM技术的日臻完善,光通信技术的不断进步,使国内未来高速铁路需要全光网络。随着光网络宽带化方向发展,传统光网络正在朝着适于传输高新业务的新一代全光网络演进。
As for home and abroad communication system for high speed railway, China＇s future high speed railway need to study and adopt the experience of abroad high speed railway. Facing rapid increase of new services and further perfection of wavelength division multiplexing technique and continuous improvement of optical communications technique, China＇s future high speed railway should use all-optical network and follow the trend of wide-band communications. Traditional optical network is evolving into new generation all-optical network, which is suitable for the transmission of new services.
