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,I-ONUizingxenye zedatha zisebenzisa i-1310nm/1490nm isignali yokubona kanyeI-ONUIngxenye ye-CATV isebenzisa isignali yokubona engu-1550nm egumbini lekhompiyutha elisekupheleni komsakazo nomabonakude ngokusebenzisa imishini yokuphindaphinda ye-WDM wavelength division ehlanganiswe nentambo ye-fiber optic, bese kuba ngokudluliswa nokubonwa kwemishini ye-ODN kuwo wonke amazinga futhi ekugcineni ifinyelele ekhaya lomsebenzisi, ekhaya lomsebenzisiI-ONUiyunithi, isebenzisa i-single fiber three-waveI-ONUI-CATV yathuthukiswa yinkampani yethu, okungukuthi, idatha kanye nomshini wokubona we-CATV 2-in-1 GPONI-ONU, ingakhipha 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 yefayibha eyodwa namagagasi amathathu kuphelela ekugcineni, kulula kakhulu ukuphathaI-ONU. Abalawuli benethiwekhi bangasebenzisa ukulethwa kwesevisi kude, ukulungisa amaphutha, futhi banike amandla/bakhubaze izinsizakalo ze-CATV ngokubheka phambiliOLTimishini.
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.
