Paenga-whāwhā 19, 2021, Ko te Hangarau Greatway i kii te tuku i te GWT3500S 1550nm kaiwhakawhiti whatu, he kotahi te putanga muka me nga whakaurunga RF e rua: kotahi mo te 45~806MHz 80ch tairitenga CATV ranei DVB-C QAM ranei DVB-T me tetahi atu mo te 950~2150MHz Satellite Input . Ka taea e GWT3500S te tuku TV tairitenga, DVB-C/T TV me te DVB-S/S2 amiorangi TV i runga i tetahi punaha FTTH. Me te whakakaha whatu kaha teitei, ka taea e GWT3500S te FTTH MSO ki te tuku pouaka whakaata tairitenga, DTT, DVB-C ranei, me te ataata amiorangi ora mai i te kaiwhakawhiti whatu kotahi. Ko te nuinga o nga pouaka whakaata pouaka whakaata kei te upoko CATV mai i nga kaiwhakarite ataata o te rohe, kua tohua te whakaata whakaata whakaata whakaata me te putanga QAM ipurangi. Inaa, ehara i te mea pai ki te huri i nga pouaka whakaata amiorangi katoa ki te CATV mena he maha nga kaupapa TV rongonui o te peerangi matua. He pai ake te tohatoha tohu amiorangi me te CATV RF. Na te nui ake o te punaha FTTH e tuku ana i te GPON mo te ratonga ipurangi, ka taea te whakawhānui atu i te roopu CATV whakamua RF ki te 45 ~ 2150MHz, tae atu ki te CATV haapurorotanga kounga teitei me te TV Satellite. Ma te hangarau DWDM, ka whakatauhia e nga miihini Hangarau Greatway tenei raru tuku raina RF whanui whanui. Ko te GWT3500S he mahi motuhake mo te CATV RF me te amiorangi TV RF, me te whakarite i nga mahi RF pai rawa atu i te roopu CATV me te roopu amiorangi. Ka taea e GWT3500S te whakaahei i te FTTH MSO ki te whakarato TV tairitenga, ratonga DVB-C/T/S i te wa ano i roto i te whatunga kotahi i te huarahi ngawari. Whai muri i te nui o nga riipene whakaata kounga teitei e haapurorohia ana i te matapihi whatu 1550nm, he pai ake te bandwidth o nga ratonga Ipurangi. Ka taea e GWT3500S te mahi me te punaha GPON, XGPON, NGPON2 FTTH. Kei Shenzhen, Ko te Hangarau Greatway he RF mo te whare hoahoa hua tuku muka me te wheketere mai i te 2004, e tuku ana i te kaiwhiwhi FTTH CATV, RFoG ONU mo te pouwhanga taura ftth, amiorangi kotahi / Mahanga / Quatro LNB RF i runga i te GPON, E rua / E wha nga peerangi mo te muka kotahi hono, 3224MHz Satellite Fiber Hononga, GPON me te GPON +, EoC, 1218MHz CATV whakawhiti mata me te node whatu, te karaehe päpäho hononga AV / ASI / SDI muka.
