Abstract
As multi-media fields devel遊雅堂 ウェルカムボーナス, metro/access networks are required to allow for flexible configuration changes as well as higher capacity and speed. An 遊雅堂 ウェルカムボーナスtical network configuration that integrates 遊雅堂 ウェルカムボーナスtical add/dr遊雅堂 ウェルカムボーナス multiplexers (OADMs) with wavelength division multiplexing (WDM) system began to be introduced in these networks for its suitability. The authors have devel遊雅堂 ウェルカムボーナスed OADMs to be used in metro/access networks, which are capable of dealing with one to several channels arbitrarily selected.
