Pakadali pano, atatu akuluakulu oyendetsa ma telecom IPTV akupitilizabe kulowerera pamsika wapa TV ndi wailesi yakanema TV, ogwiritsa ntchito wailesi ndi wailesi yakanema akukumana ndi kutayika kwakukulu kwa ogwiritsa ntchito, kusintha kwachitukuko kwa wailesi ndi kanema wawayilesi kuli pafupi, tinganene kuti ndani amawongolera. pabalaza yemwe walanda wogwiritsa ntchito. Bizinesi yayikulu yamawayilesi ndi wailesi yakanema imaphatikizapo bizinesi yawayilesi 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 ya wailesi ndi kanema wawayilesi ndi ntchito yomanga ya FTTH ya njira ziwiri. Kuphatikizidwa ndi zinthu zomwe zilipo pawailesi ndi kanema wawayilesi, FTTH imagwiritsa ntchito njira yolumikizirana yomwe ilipo pamakampani: single fiber three wave and burodibandi service access solution. Lero, mkonzi amakufotokozerani izi.
Mu single fiber three-wave and broadband service access solution,ONUZigawo za data zimagwiritsa ntchito 1310nm/1490nm optical sign ndiONUGawo la CATV limagwiritsa ntchito chizindikiro cha 1550nm kutsogolo kutsogolo kwa kompyuta yawailesi ndi wailesi yakanema kudzera pa WDM wavelength division multiplexing zida zophatikizika ndi chingwe cha fiber optic, ndiyeno kudzera pakupatsirana ndi kuwonera kwa zida za ODN pamilingo yonse ndikufikira kunyumba kwa wogwiritsa ntchito, m'nyumba ya ogwiritsaONUunit, pogwiritsa ntchito single fiber three waveONUCATV opangidwa ndi kampani yathu, ndiye deta ndi CATV kuwala makina 2-mu-1 GPONONU, imatha kutulutsa mwachindunji ma siginecha a TV ndi ma sigino a data a Broadband. 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. Kutha-kumapeto kasamalidwe: Popeza kamangidwe ka netiweki ka ulusi umodzi ndi mafunde atatu ndi kumapeto mpaka kumapeto, ndikosavuta kusamaliraONU. Oyang'anira ma netiweki amatha kukhazikitsa ntchito zakutali, kukonza zolakwika, ndikuyambitsa / kuletsa ntchito za CATV kumapetoOLTzida.
2. Mtengo wotsika wa ODN: Popeza chizindikiro cha TV chowulutsa ndi chizindikiro cha data cha Broadband chimafalitsidwa pamtundu womwewo wakuthupi, yankho ili limachepetsa kwambiri mtengo womanga wa zipangizo za ODN kuchokera kutsogolo kupita kunyumba ya wogwiritsa ntchito.
