Raws li CableLabs, DOCSIS 4.0 muaj 1800MHz bandwidth rau 10Gbps downstream cov ntaub ntawv thiab 6Gbps upstream cov ntaub ntawv ntxiv rau tshaj tawm cov yeeb yaj kiab CATV.Ua haujlwm nrog cov khoom siv tseem ceeb, Greatway Technology's RFoG Micronode tshiab tuaj yeem muab 1800MHz mus rau txoj kev CATV bandwidth thaum ua tau raws li txhua tus qauv uas tau teev tseg los ntawm SCTE-174-2010.Ntawm 1800MHz, coaxial cable muaj ntau yam attenuation piv nrog 1000MHz los yog 1218MHz, Docsis tshaj fiber ntau los yog Docsis tshaj PON (D-PON) yog lub prevailing network, fiber rau qhov chaw (FTTP) los yog fiber ntau rau lub tsev (FTTH) yuav tsum kev thov.Tsis tas li ntawd, Docsis 4.0 thov rov qab txoj hauv kev sib txuas ntau dua ntawm CATV bandwidth qis, kho qhov muag cuam tshuam cuam tshuam (OBI) yog qhov nyuaj dua hauv PON system.Nrog built-in uncooled CWDM rov qab txoj kev laser ntawm lub qhov rais xaiv optical, GFH2009 RFoG Micronode paub txog OBI kev thov dawb hauv PON system ntawm kev siv nyiaj txiag, muaj qhov zoo ntawm kev tshaj tawm ntau pua HD TVs thiab sib koom 10Gbps Ethernet cov ntaub ntawv.Video thiab Internet yog cov ntaub ntawv tseem ceeb ntawm kev vam meej niaj hnub no.CATV thiab Satellite TV yog qhov pheej yig tshaj plaws ntawm kev tshaj tawm TVs, kev sib tham video zoo dua hauv internet.MSO tshiab tuaj yeem xaiv GPON / XGPON los muab kev pabcuam hauv internet.Cov neeg siv qub cable modem nyiam txuas ntxiv lawv cov cuab yeej siv tau zoo thiab kev saib xyuas kev paub.Kev sib xyaw ua ke zoo ntawm kev tshaj tawm cov yeeb yaj kiab thiab kev sib tham video tuaj yeem txhim kho tus nqi ntawm lub network.Rau cov neeg siv khoom nyiam siv cable modem, GFH2009 RFoG micronode tuaj yeem ua tau zoo fiber ntau rau coaxial cable converter.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.
