GWT3500S CATV+SAT 1550nm Kaituku Matapihi
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.
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.
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.
Ētahi atu āhuatanga:
•Haruru iti teitei linearity DFB taiaho.
•Ko te whakaurunga CATV RF motuhake me te whakaurunga RF Satellite.
•Tautoko ake ki te 32 transponders i runga i te amiorangi 950~2150MHz RF.
•Tautoko ake ki te 80ch NTSC tairitenga TV QAM ranei i runga i te 45~806MHz RF.
•Ko te pae o mua ka whakaatu a VFD i nga tawhā mana me te karere mahi.
