光纤密集波分复用(Dense Wavelength Division Multiplexing)技术,也就是人们常说的DWDM,指的是一种光纤数据传输技术,这一技术利用激光的波长按照比特位并行传输或者字符串行传输方式在光纤内传送数据。 DWDM是光纤网络的重要组成部分,它可以让IP协议、ATM和同步光纤网络/同步数字序列(SONET/SDH)协议下承载的电子邮件、视频、多媒体、数据和语音等数据都通过统一的光纤层传输。

Dense Wavelength Division Multiplexing (DWDM) is a kind of optical fiber data transmission technology, which uses the wavelength of laser to transmit data in the optical fiber in parallel or in serial mode. DWDM is an important component of optical fiber network. It enables data such as e-mail, video, multimedia, data and voice carried by IP protocol, ATM and synchronous optical fiber network/synchronous digital sequence (SONET/SDH) protocol to be transmitted through a unified optical fiber layer.
