光通信中的光电子器件讲座第五讲 现代光纤通信中的波分复用技术

WAVELENGTH DIVISION MULTIPLEXING IN MODERN OPTICAL FIBER TELECOMMUNICATIONS

波分复用技术在现代光纤通信中发展十分迅速 ,已展现出巨大的生命力和光明的发展前景 .中国的骨士网和一些局域网已开始采用波分复用技术 ,国内一些厂商也正在开发这项技术 .文章详细介绍了波分复用技术的发展背景、原理、组成形式、实现方案及其国内外发展情况 .

Wavelength division multiplexing(WDM)has developed quickly in modern optical fiber communications. It exhibits tremendous vitality and has bright prospects. WDM has been put into use in backbone networks and various local area networks in China, and is being developed by certain domestic companies too. We present the background,principle, structure, realitation and development of WDM both at home and abroad.
