GLB3500A-2T Terr TV me Twin LNB Optical Transmitter
Whakaahuatanga Hua
Ko te GWT3500S he whakawhiti tika 1550nm DFB laser mo te tohatoha muka. Ko te GWT3500S tetahi 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.
E whakarato ana a GWT3500S i te TV tairitenga, nga ratonga DVB-C/T/S 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.
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 mahi a GWT3500S ki te CATV RF me te pouaka whakaata TV RF motuhake, me te whakarite i nga mahi RF pai i te roopu CATV me te roopu peerangi.
