摘要
随着光传送网(OTN)的广泛商用,可重构型光分插复用器(ROADM)技术逐渐成为OTN的重要光节点技术。文章分析了ROADM的3种主要技术,并针对不同的网络用途给出了选用建议。最后提出一种复合型ROADM设备形态,该设备形态结合了波长阻断器和波长选择开关型ROADM技术的优点,具有更强的适用性。
With the extensive commercial applications of Optical Transport Networks（OTN）,ROADM technology is gradually becoming one of its important node technologies.This paper analyzes three main ROADM technologies,gives suggestions for its selections for different network applications and proposes a hybrid ROADM equipment pattern,which combines the advantages of two ROADM technologies that are based respectively on wavelength blockers and wavelength selective switches,and has still better applicability.
