【正文】 according to the American Mai Kenxi Company39。 SBC in the plan plans in 2020 in its huge “speed of light” to reach 18,000,000 FTTN, each household has speed 2039Mb/s, provides the endtoend tertiary service colligation (trite play) the service. Japan is in the world advances the FTTH most radical country, years its optical fiber on already understood more than 18,000,000 households families, but the user development lag, probably was 2,000,000, in 2020 plans develops 10,000, quite is steady conservatively, FTTH altogether has laid to 2020 500,000, some 167 small projects or the experimental project are carrying on. Our country broadband access work extremely is also rapid in the near two year development, according to the preliminary statistics, to 2020 year39。s end, the total number of users already achieved 150,000,000, became in the electricity reliable historical account to develop one of quickest telemunication 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 years, but the broadband access service has only used for years. According to the IDC forecast, in 2020 the global wide band total user may achieve 209,000,000, in which , namely about 20,000,000 users for optical fiber access work. The Asian and Pacific area, specially South Korea39。 Wide band optical fiber access work trend of development Author: Liu Jinhai article source: Computer universal time: 202038 This article first is brief introduced the world broadband access work develops the condition and the main application, next narrated the wide band optical fiber access work merit. With emphasis has once more analyzed the wide band pointtopoint active Ether optical fiber system and the wide band to the passive optical fiber system characteristic and the application. Meets down proposed our country optical fiber access work sends chem. possible to surmount APON, BPON and the EPON stage, starts from the wide band pointtopoint Ether optical fiber system and GEPON, finally and even transits to the GPON stage preliminary idea. Finally analyzed the optical fiber munications technology trend of development from each angle. The broadband access work develops condition and main application In fact, looking from the telemunication development history, when the work number of users achieves certain scale. Each kind of application meets the nature production。 this also is socalled 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 munication or the Inter, on its short note, the browsing, the 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 work entered the big development phase. To 2020 year39。s 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 Inter 90%. Japanese Government also vigorously advances the wide band development through each measure, plans in 2020 to enhance the wide band user total to 30,000,000, in which FTTH achieves 1 10, still is the world biggest broadband access market, the total number of users surpasses 30,000, FOC the wide band service localization is one of 20202020 year six big goals, in fact the broadband access is being the American universal service the next goal. The US broadband access is primarily develops by the cable television and ADSL, because the telemunication control policy encouragement uses the new technical construction work (. FCC stipulation operation business construction optical fiber access work to be possible not limited the pressure which in local ring circuit noncolligation policy) as well as the petition and the service grows, recently leads the operation business to be extremely positive to the optical fiber to the station (FTTP) development. Speaking of the optical fiber access work, specially the optical fiber to station (FTTP) or optical fiber proficient (FTTH), the whole world already started to enter the unloading phase, only US had 270 FTTP projects, was mostly the local authority, the public pany, the property developer and the nonleading telemunication operation business project. Leading operation business also starts to enter this domain, in which Version plans in 2020 to plete 3,000,000 FTTP。s end our country wide band user is 25,000,000, bees is inferior to US39。s newest analysis, the initial period wide band application mainly is the high speed surfer, may make the surfer the time to increase approximately 30%.Hereafter, along with the service largescale development, develops the power which the new service bees continues to develop. According to American BHK Corporation demonstrated in 2020 investigation result that, in 2020 the American first five wide band expense was on the gambles, the adult program, the game, music downloading and the selection and broadcast television, had obviously to the expense class incline tendency. Needs to point out that, discusses needs to pay attention to in a basic understanding using the actuation the erroneous zone, namely cannot place hopes in artificially studies beforehand develops 12 items socalled “the Assassin39。 this also is socalled 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 munication or the Inter, on its short note, the browsing, the chats and so on the key applicatio
