Njengamanje, opharetha abathathu abakhulu be-telecom I-IPTV bayaqhubeka nokungena emakethe ye-TV ye-TV yendabuko kanye nabaqhubi bethelevishini, opharetha bomsakazo kanye nethelevishini babhekene nenani elikhulu lokulahlekelwa kwabasebenzisi, ukuguqulwa kokuthuthukiswa komsakazo kanye nomabonakude kuseduze, kungathiwa ngubani olawulayo. igumbi lokuphumula elibambe umsebenzisi.Ibhizinisi eliyinhloko labaqhubi bomsakazo nethelevishini lihlanganisa kokubili ibhizinisi lomsakazo nethelevishini kanye nedatha yesevisi yezindlela ezimbili (ukufinyelela ku-inthanethi / i-VOD / IPTV / e-government / imidlalo ehlangene) kanye nezinsizakalo ze-Broadband, ngakho-ke ukwakhiwa kwe-FTTH yomsakazo nethelevishini kufanele kuhilele Ukwakhiwa kwe-FTTH kwebhizinisi lomsakazo nethelevishini kanye nokwakhiwa kwe-FTTH yesevisi yezindlela ezimbili.Ihlanganiswe nezinsiza ezikhona zomsakazo nethelevishini, i-FTTH ngokuyinhloko yamukela isisombululo samanje esivamile embonini: i-fiber eyodwa yamaza amathathu kanye nesixazululo sokufinyelela kwesevisi ye-broadband.Namuhla, umhleli uyakuchazela kakhulu.
Kusixazululo sokufinyelela sesevisi ye-fiber three-wave kanye ne-broadband, izingxenye zedatha ze-ONU zisebenzisa isignali yokubona engu-1310nm/1490nm kanye nengxenye ye-ONU CATV isebenzisa isignali yokubona engu-1550nm ekamelweni elingaphambili lekhompiyutha lomsakazo nomabonakude ngokusebenzisa imishini ye-WDM wavelength division multiplexing ehlanganiswe ne- ikhebula le-fiber optic, bese kuthi ngokudluliswa kanye ne-spectroscopy yemishini ye-ODN kuwo wonke amazinga futhi ekugcineni ifinyelele ekhaya lomsebenzisi, ekhaya lomsebenzisi iyunithi ye-ONU, isebenzisa i-fiber eyodwa yamagagasi amathathu i-ONU CATV eyakhiwe inkampani yethu, okungukuthi, idatha kanye Umshini wokubona we-CATV ongu-2-in-1 GPON ONU, ungakhipha ngokuqondile amasiginali we-TV namasignali edatha ye-broadband.Ngesikhathi esifanayo, ngokusekelwe kulesi sixazululo, opharetha bomsakazo nethelevishini bangaphinde bathuthukise abasebenzisi be-broadband, babone ukukhiqizwa kwemali engenayo yezinsizakalo eziningi, futhi banciphise izindleko zokwakha inethiwekhi.
Izinzuzo zesixazululo sokufinyelela kwe-single-fiber-wave three-wave zimi kanje:
1. Ukuphathwa kokuphela kuya ekupheleni: Njengoba ukwakhiwa kwenethiwekhi ye-fiber eyodwa namagagasi amathathu kuphelile, kulula kakhulu ukuphatha i-ONU.Abalawuli benethiwekhi bangasebenzisa ukulethwa kwesevisi okukude, ukulungisa amaphutha, futhi banike amandla/bakhubaze izinsizakalo ze-CATV ngempahla ye-OLT engaphambili.
2. Izindleko eziphansi ze-ODN: Njengoba isignali ye-TV esakazwayo kanye nesignali yedatha ye-broadband idluliselwa ngefayibha engokoqobo efanayo, lesi sixazululo sehlisa kakhulu izindleko zokwakha zezinsiza ze-ODN kusukela ekuqaleni kuya ekhaya lomsebenzisi.
