Pakali pano, atatu akuluakulu oyendetsa ma telecom IPTV akupitirizabe kusokoneza msika wa TV ndi wailesi yakanema TV, oyendetsa wailesi ndi wailesi yakanema akukumana ndi chiwerengero chachikulu cha kutayika kwa ogwiritsa ntchito, kusintha kwa chitukuko cha wailesi ndi kanema wawayilesi kwayandikira, tinganene kuti ndani amene amalamulira. pabalaza yemwe walanda wogwiritsa ntchito.Bizinesi yayikulu ya ogwiritsa ntchito pawailesi yakanema ndi wailesi yakanema imaphatikizapo bizinesi yamawayilesi ndi kanema wawayilesi komanso ntchito zanjira ziwiri (kugwiritsa ntchito intaneti / VOD / IPTV / e-government / masewera olumikizana) ndi ntchito za Broadband, kotero kuti FTTH yomanga wailesi ndi kanema wawayilesi iyenera kuphatikiza FTTH yomanga bizinesi yamawayilesi ndi kanema wawayilesi ndi ntchito yomanga ya FTTH ya njira ziwiri.Kuphatikizidwa ndi zinthu zomwe zilipo kale pawailesi ndi kanema wawayilesi, FTTH imagwiritsa ntchito njira yomwe ikugwiritsidwira ntchito pamakampani: single fiber three-wave and burodiband service access solution.Lero, mkonzi amakufotokozerani izi.
Mu njira imodzi yopezera chithandizo cha fiber three-wave ndi burodibandi, zigawo za data za ONU zimagwiritsa ntchito siginecha ya 1310nm/1490nm ndipo gawo la ONU CATV limagwiritsa ntchito 1550nm optical sign muchipinda chakutsogolo chapakompyuta cha wailesi ndi wailesi yakanema kudzera pa WDM wavelength division multiplexing zida kuphatikiza CHIKWANGWANI chamawonedwe chingwe, ndiyeno kudzera kufala ndi spectroscopy wa zida ODN pa misinkhu yonse ndipo potsiriza kufika kunyumba wosuta, mu wosuta kunyumba ONU unit, ntchito limodzi CHIKWANGWANI atatu yoweyula ONU CATV opangidwa ndi kampani yathu, ndiko kuti, deta ndi CATV kuwala makina 2-mu-1 GPON ONU, akhoza mwachindunji linanena bungwe TV siginecha ndi siginecha burodibandi deta.Nthawi yomweyo, kutengera yankho ili, ogwiritsa ntchito wailesi ndi wailesi yakanema amathanso kupanga ogwiritsa ntchito ma Broadband, kuzindikira zopezera ntchito zambiri, ndikuchepetsa ndalama zomanga maukonde.
Ubwino wa single-fiber three-wave access solution ndi motere:
1. Kumapeto-kumapeto kasamalidwe: Popeza mapangidwe a maukonde a fiber imodzi ndi mafunde atatu amatha kumapeto, ndi bwino kuyang'anira ONU.Oyang'anira ma netiweki amatha kugwiritsa ntchito ntchito zakutali, kukonza zolakwika, ndikuyambitsa/kuletsa ntchito za CATV kudzera pa zida zakutsogolo za OLT.
2. Mtengo wotsika wa ODN: Popeza kuti chizindikiro cha TV chowulutsa ndi chizindikiro cha data cha Broadband chimafalitsidwa pamtundu womwewo wa thupi, yankho ili limachepetsa kwambiri mtengo wa zomangamanga wa zipangizo za ODN kuchokera kutsogolo kupita kunyumba ya wogwiritsa ntchito.
