Lub Plaub Hlis 19, 2021, Greatway Technology tshaj tawm tso GWT3500S 1550nm optical transmitter

Lub Plaub Hlis 19, 2021, Greatway Technology tshaj tawm tso GWT3500S 1550nm optical transmitter, uas muaj ib qho fiber ntau tso tawm thiab ob lub RF inputs: ib qho rau 45 ~ 806MHz 80ch analog CATV lossis DVB-C QAM lossis DVB-T thiab lwm yam rau 950 ~ 2150MHz Satellite . GWT3500S tuaj yeem xa cov TV analog, DVB-C / T TV thiab DVB-S / S2 satellite TV hla txhua qhov FTTH. Ua ke nrog lub zog loj optical amplifier, GWT3500S enables FTTH MSO muab analog TV, DTT los yog DVB-C, thiab nyob satellite video los ntawm ib qho optical transmitter. Feem ntau tshaj tawm TV RFs ntawm CATV headend yog los ntawm lub zos video modulators, xaiv satellite video re-modulation thiab internet QAM tso zis. Qhov tseeb, nws tsis yog kev lag luam los hloov tag nrho satellite TV rau CATV yog tias lub ntsiab satellite muaj ntau cov ntsiab lus TV nrov. Nws muaj txiaj ntsig zoo dua los faib cov teeb liab satellite nrog rau CATV RF. Nrog ntau thiab ntau FTTH system xa GPON rau kev pabcuam hauv internet, cov tsoos CATV rau pem hauv ntej RF bandwidth tuaj yeem txuas ntxiv mus rau 45 ~ 2150MHz, suav nrog kev nplua nuj tshaj tawm CATV thiab Satellite TV. Los ntawm txoj kev ntawm DWDM thev naus laus zis, Greatway Technology engineers daws qhov teeb meem dav dav RF linear kis tau tus mob. GWT3500S deals nrog CATV RF thiab satellite TV RF cais, kom ntseeg tau tias qhov zoo tshaj plaws RF kev ua tau zoo ntawm CATV band thiab satellite band feem. GWT3500S tuaj yeem pab FTTH MSO muab analog TV, DVB-C/T/S cov kev pabcuam tib lub sijhawm hauv ib lub network ntawm txoj kev yooj yim tshaj plaws. Tom qab cov yeeb yaj kiab zoo tshaj plaws tau tshaj tawm ntawm 1550nm optical qhov rais, kev pabcuam hauv Is Taws Nem muaj txiaj ntsig zoo dua bandwidth. GWT3500S tuaj yeem ua haujlwm nrog GPON, XGPON, NGPON2 FTTH system. Nyob rau hauv Shenzhen, Greatway Technology yog RF tshaj fiber ntau kis tau tus mob khoom tsim lub tsev thiab Hoobkas txij li thaum 2004, muab FTTH CATV receiver, RFoG ONU rau ftth cable modem, satellite ib leeg / Twin / Quatro LNB RF tshaj GPON, Ob / Plaub satellites tshaj ib fiber. txuas, 3224MHz Satellite Fiber Txuas, GPON thiab GPON +, EoC, 1218MHz CATV optical transmitter thiab optical node, tshaj tawm hauv chav kawm AV / ASI / SDI fiber ntau txuas.
