Na te whanaketanga tere o te pūtaiao me te hangarau, kua horahia te hangarau FTTH (Fiber To The Home), me China Telecom, China Mobile, China Unicom e toru nga kaiwhakahaere o te whatunga whakawhitiwhitinga kua oti te whakaurunga pakeke-nui, me te mea ko teONU(pouwhanga whatu) kua riro he taputapu e tika ana mo te taiao whatunga kāinga.Ko te tuku ihoONUtango i te maramara whakauru nui-nui, e tohuhia ana e te ara iahiko ngawari, te iti o te kohi hiko me te tino pono.ONUkua kore e taea ki te whakatutuki i nga hiahia o te hanga me te oranga o te tangata, me te mahi-mahaONUi puta mai.
He aha te mahi-mahaONU, ko te ingoa e kii ana, i roto i te hangarau whakarereke taketake, he maha nga taapiri penei i te ratonga rokiroki USB, V o IP (Voice over Internet Protocol IP based voice transmission), CATV (Community Antenna Television) Ratonga, WIFI mahi me etahi atu raupapa.
He tohunga ngaio a Shenzhen HDV Photoelectron Technology Ltd.(HDV).ONUKo te kaihanga taputapu he kaiwhakawhanake kaupapa korero mohio hoki, kei te hokona e ta maatau kamupene nga momo taputapu korero o runga me raro, penei i te: kaitahuri muka, te whakawhiti Ethernet,OLTtaputapu,ONUtaputapu me etahi atu.Ki te hiahia koe ki te mohio atu mo te hangarau korero, nau mai ki te whakapiri mai ki a matou i nga wa katoa.
He maha-mahi AC rua-auauONUhe hua HGU (waewae kuwaha kaainga) i hangaia i roto i nga momo otinga FTTH, ma te whakamahi i nga tono FTTH taumata-kaikawe hei whakarato i te urunga pakihi raraunga ki nga ratonga rokiroki USB, ratonga tuku reo V o IP me nga ratonga CATV. TeneiONUKo te hua kei runga i te hangarau XPON pakeke, pumau, whai hua me te pai.Ka taea e ia te tautoko i te EPON me te aratau GPON te whakawhiti aunoa, ina hono ana ki te EPONOLTGPON raneiOLT, Ka taea e ia te kite aunoa me te huri ki te aratau EPON me te GPON. Tautoko i te PPPOC / IPOE / te ararere IP me te aratau piriti, tautoko IEEE802.11b / g / n / ac (2.4G me 5G WiFi), te tere o te whakawhitiwhiti korero WiFi ki te 1200Mbps / s.He nui te ti'aturi, te whakahaere ngawari, te ngawari o te whirihoranga me te kounga o te ratonga pai (QoS) nga ahuatanga whakapumautanga, ki te whakatutuki i te China Telecom passive optical network EPON te uru hangarau me te ITU-TG.Ko te 984.X's GPON Hangarau Paerewa.Ka taea te urutau ki te taiao whatunga uaua me te rerekee o naianei.
