Okwangoku, i-IPTV, abaqhubi abathathu abakhulu bonxibelelwano, ihlala ingena kwimarike yeTV yerediyo kunye nabaqhubi bakamabonakude. Abasebenzi bakanomathotholo nomabonakude bajongene nenani elikhulu lelahleko yabasebenzisi, kwaye inguqu yophuhliso lukanomathotholo nomabonakude sele kumbovu. Kunokuthiwa nabani na olawula igumbi lokuhlala ubamba abasebenzisi. Ishishini eliphambili labaqhubi boonomathotholo kunye nomabonakude libandakanya zombini iinkonzo zikanomathotholo kunye nomabonakude kunye neenkonzo zedatha yeendlela ezimbini (ukufikelela kwi-Intanethi/i-VOD/IPTV/e-government/imidlalo esebenzisanayo) kunye neenkonzo zebroadband. Ngoko ke, ukwakhiwa kwe-FTTH yerediyo kunye nomabonwakude ngokuqinisekileyo kubandakanya ukwakhiwa kwe-FTTH yeenkonzo zikanomathotholo kunye nomabonwakude kunye nokwakhiwa kwe-FTTH yeenkonzo zedatha yeendlela ezimbini. Ukudibanisa izibonelelo ezikhoyo zikanomathotholo kunye nomabonwakude, ukuphunyezwa kwe-FTTH ikakhulu kwamkela isisombululo esikhoyo ngoku kwishishini: ifayibha enye yamaza amathathu + isisombululo sokufikelela kwinkonzo yebroadband. Namhlanje, umhleli uya kukuchazela ubukhulu becala.
Kwifayibha enye i-wave three wave+broadband access service scheme, iI-ONUicandelo ledatha yekati ebonayo lisebenzisa i-1310nm/1490nm imiqondiso yokubona, kunyeI-ONUIcandelo le-CATV lisebenzisa iimpawu ze-1550nm zamehlo. Kwigumbi likanomathotholo kunye nomabonwakude ngaphambili, i-WDM wavelength division multiplexing izixhobo zidityaniswe nentambo yefiber optic, kwaye emva koko idlula kwi-transmission kunye nokuqhekeka kwamanqanaba ahlukeneyo ezixhobo ze-ODN ngaphambi kokufikelela kwikhaya lomsebenzisi. KwiI-ONUiyunithi yekati ye-optical yekhaya lomsebenzisi, ifayibha enye yamaza amathathuI-ONUI-CATV ephuhliswe yinkampani yethu isetyenziswa, oko kukuthi, idatha + CATV optical kunye noomatshini ababini kwiGPON enyeI-ONU, enokuthi ikhuphe ngokuthe ngqo izibonakaliso zethelevishini kunye neempawu zedatha ye-broadband. Kwangaxeshanye, oonomathotholo kunye nabaqhubi bakamabonakude banokuphinda baphuhlise abasebenzisi be-broadband esekwe kwesi sikimu, bafezekise ukuveliswa kwengeniso yeenkonzo ezininzi, kunye nokunciphisa iindleko zokwakha inethiwekhi.
Izinto eziluncedo zesikimu sofikelelo lwamaza osinga ntathu zezi zilandelayo:
1. Ulawulo oluphelayo ukuya ekupheleni: Ngenxa yokwakhiwa kwenethiwekhi yokuphela kokuphela kwefayibha ezintathu zamaza, kulungele kakhulu ukulawula.I-ONUiikati zamehlo. Abaphathi benethiwekhi banokusebenzisa imisebenzi efana nokuhanjiswa kwenkonzo ekude, ukugcinwa kwempazamo, kunye nokuvula / ukuvala iinkonzo ze-CATV ngesiphelo sangaphambili.OLTizixhobo.
2. Ixabiso eliphantsi le-ODN: Ngenxa yokuba iimpawu ze-TV ezisasazwayo kunye neempawu zedatha ye-broadband zihanjiswa kwi-fiber ebonakalayo ebonakalayo, esi sikimu sinciphisa kakhulu iindleko zokwakhiwa kwezixhobo ze-ODN ukusuka phambili ukuya kwikhaya lomsebenzisi.
