Wide band optical fiber access network trend of development The broadband access network develops condition and main application In fact, looking from the telecommunication development history, when the network number of users achieves certain scale. Each kind of application meets the nature production; this also is so-called steps the Cuff law might to be at especially. In the history one kind of technology since birth has not been having a big pile of application, regardless of is the mobile communication or the Internet, on its short note, the browsing, the net chats and so on the key applications all is develops certain degree after the user scale to produce naturally, but is not sedulously designs beforehand plans. Since has entered for the 21st century, the whole world broadband access network entered the big development phase. To 2004 years end, the total number of users already achieved 150,000,000, became in the electricity reliable historical account to develop one of quickest telecommunication services, and even was also quicker than the mobile service. For example the whole world mobile service from 10,000,000 developed to 100,000,000 has spent for 5.5 years, but the broadband access service has only used for 3.5 years. According to the IDC forecast, in 2007 the global wide band total user may achieve 209,000,000, in which 9.9, namely about 20,000,000 users for optical fiber access network. The Asian and Pacific area, specially South Koreas and Japan were the broadband access develop the swiftest most and violent country, the South Korean wide band user total already break through 10,000,000, the wide band popular rate occupied the world first, hold family 7 Internet 90%. Japanese Government also vigorously advances the wide band development through each measure, plans in 2005 to enhance the wide band user total to 30,000,000, in which FTTH achieves 1 10,000.US still is the world biggest broadband access market, the total number of users surpasses 30,0
