    Litharollo tsa marang-rang tsa All-optical network bakeng sa basebelisi ba seea-le-moea le thelevishene

    Nako ea poso: Apr-18-2022

    Hona joale, basebetsi ba bararo ba ka sehloohong ba thelevishene IPTV ba ntse ba tsoela pele ho kena-kenana le 'maraka oa setso oa seea-le-moea le thelevishene, basebelisi ba seea-le-moea le thelevishene ba tobane le tahlehelo e kholo ea basebelisi, phetoho ea tsoelo-pele ea seea-le-moea le thelevishene e haufi, ho ka boleloa hore ke mang ea laolang. kamore ya ho phomola e hapileng mosebedisi. Khoebo ea mantlha ea basebelisi ba seea-le-moea le thelevishene e kenyelletsa khoebo ea seea-le-moea le thelevishene le lits'ebeletso tsa lits'ebeletso tse peli (ho fumana marang-rang / VOD / IPTV / e-government / lipapali tse sebetsanang) le lits'ebeletso tsa Broadband, ka hona, kaho ea FTTH ea seea-le-moea le thelevishene e tlameha ho kenyelletsa FTTH kaho ea khoebo ea seea-le-moea le thelevishene le khaho ea FTTH ea ts'ebeletso ea mekhoa e 'meli ea data. Ha e kopantsoe le lisebelisoa tse teng tsa seea-le-moea le thelevishene, FTTH haholo-holo e amohela tharollo ea hona joale e ka sehloohong indastering: tharollo e le 'ngoe ea fiber three-wave le broadband access service. Kajeno, mohlophisi o u hlalosetsa eona haholo-holo.

    Tharollong ea phihlello ea ts'ebeletso e le 'ngoe ea fiber three-wave le Broadband,ONUlikarolo tsa data li sebelisa 1310nm / 1490nm optical signal leONUKarolo ea CATV e sebelisa lets'oao la optical la 1550nm kamoreng e ka pele ea komporo ea seea-le-moea le thelevishene ka lisebelisoa tsa WDM wavelength division multiplexing tse kopantsoeng le thapo ea fiber optic, ebe ka phetisetso le spectroscopy ea lisebelisoa tsa ODN maemong ohle mme qetellong e fihla lapeng la mosebelisi. lapeng la mosebedisiONUunit, e sebelisang leqhubu le le leng la fiber e meraroONUCATV e ntlafalitsoeng ke k'hamphani ea rona, ke hore, data le mochini oa optical oa CATV 2-in-1 GPONONU, e ka hlahisa ka ho toba lipontšo tsa TV le matšoao a data a Broadband. Ka nako e ts'oanang, ho itšetlehile ka tharollo ena, basebetsi ba seea-le-moea le thelevishene ba ka boela ba hlahisa basebelisi ba marang-rang, ba hlokomela tlhahiso ea chelete e ngata ea litšebeletso, 'me ba fokotsa litšenyehelo tsa kaho ea marang-rang.

    Melemo ea tharollo ea single-fiber three-wave access ke e latelang:

    1. Tsamaiso ea ho qetela: Kaha meralo ea marang-rang ea fiber e le 'ngoe le maqhubu a mararo e ea qetellong, ho bonolo haholo ho laolaONU. Batsamaisi ba marang-rang ba ka kenya tšebetsong litšebeletso tse hole, ho lokisa liphoso, le ho nolofalletsa / ho tima lits'ebeletso tsa CATV ka peleOLTthepa.

    2. Litšenyehelo tse tlaase tsa ODN: Kaha pontšo ea thelevishene e phatlalatsoang le pontšo ea data ea broadband e fetisoa ka fiber e tšoanang ea 'mele, tharollo ena e fokotsa haholo litšenyehelo tsa kaho ea lisebelisoa tsa ODN ho tloha ka pele ho ea lehaeng la mosebedisi.
