Product Description

GWT3500S yog ib qho kev hloov pauv ncaj qha 1550nm DFB laser transmitter rau fiber ntau ntom. GWT3500S muaj ib tug fiber ntau tso zis thiab ob RF inputs: ib tug rau 45 ~ 806MHz 80ch analog CATV los yog DVB-C QAM los yog DVB-T thiab lwm yam rau 950 ~ 2150MHz Satellite Input. 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 txhais tau tias ntawm DWDM thev naus laus zis, GWT3500S cuam tshuam nrog CATV RF thiab satellite TV RF cais, kom ntseeg tau tias qhov ua tau zoo tshaj plaws RF ntawm CATV band thiab satellite band feem.

GWT3500S muab analog TV, DVB-C/T/S cov kev pab cuam ntawm ib tug yooj yim txoj kev. 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.
