In recent years, with the development of network technology and emergence of global Internet business, new Internet applications has a trend of explosive growth. Internet alone is introducing millions of individuals to a new world of information and technology. The demand for increasing bandwidth (voice, video, and data traffic) continues to drive the demand for fiber optical networks. Development of fiber optic transmission technology makes network transmission bandwidth be continuously increased. The methods to expand the backbone network capacity based on the optical fiber communication mainly include DWDM.
