WDM technology is a method for increasing the transmission capacity of optical fiber, but the transmission performance in WDM system with high speed and long distance is limited.

波分复用(WDM)技术是增大光纤传输容量的方法，但是在高速率、长距离wdm系统中传输性能受到限制。

All optical network (AON) and wavelength division Multiplexing (WDM) are the foreland of network research all over the field, their integration all optical WDM network is the hotspot.

全光通信网和波分复用技术是目前国内外网络技术研究的前沿，尤其是将两者结合起来的全光波分复用网络更是研究的热点。

Much work related to traffic grooming has been done in WDM/SDH rings, and the work is relatively less in WDM mesh networks.

SDH环网中的业务量疏导已得到大量研究，WDM网状网中的业务流疏导问题研究相对较少。

The World Development Movement (WDM) is keen to curb this betting on prices.

FORBES: China Tackles Inflation. Food Prices Rising. Good For Monsanto & Syngenta.

This feat (called wave-division multiplexing, or WDM) was the basis of Ciena's founding.

FORBES: Telltale numbers

WDM, a technique that allows a single optical path to carry thousands of parallel channels, as long as each is encoded in a slightly different colour.
