Zvinoenderana neCableLabs, DOCSIS 4.0 ine 1800MHz bandwidth ye10Gbps yakadzika dhata uye 6Gbps kumusoro kwedata mukuwedzera pakutepfenyura mavhidhiyo eCATV.Kushanda nevashambadziri vechikamu chakakosha, Greatway Technology's RFoG Micronode inogona kupa 1800MHz yekumberi nzira CATV bandwidth ichisangana ese zviyero zvinotsanangurwa neSCTE-174-2010.Pa 1800MHz, coaxial tambo ine yakawedzera attenuation kana ichienzaniswa ne1000MHz kana 1218MHz, Docsis pamusoro pefiber kana Docsis pamusoro pePON (D-PON) ndiyo inetiweki iripo, faibha kunzvimbo (FTTP) kana faibha kuenda kumba (FTTH) ndiyo ichave iyo. kudiwa chaiko.Uye zvakare, Docsis 4.0 inokumbira imwe nzira yekudzoka nzira yekubatanidza kune yakaderera CATV bandwidth, optical beat interference (OBI) chinhu chinonyanya kunetsa muPON system.Iine yakavakirwa-mukati isina kunyoroveswa CWDM yekudzoka nzira laser pane yakasarudzwa optical hwindo, GFH2009 RFoG Micronode inoona OBI yemahara kudiwa muPON system pabhajeti rehupfumi, ine zvakanakira kutepfenyura mazana eHD TV uye kugovera 10Gbps Ethernet data.Vhidhiyo neInternet ndizvo zvinotakura ruzivo mubudiriro yemazuva ano.CATV neSatellite TV ndiyo nzira yakachipa yekutepfenyura maTV, vhidhiyo inopindirana iri nani kubva painternet.MSO itsva inogona kusarudza GPON/XGPON kupa internet service.Vaimbove vashandisi tambo modem vanofarira kuwedzera midziyo yavo yavakajaira uye ruzivo rwekugadzirisa.Musanganiswa unoshanda wekutepfenyura vhidhiyo uye inofambidzana vhidhiyo inogona kuwedzera kukosha kwetiweki.Kune vanyoreri vanosarudza tambo modem, GFH2009 RFoG micronode inogona kuva yakavimbika fiber kune coaxial tambo inoshandura.Iri muShenzhen, Greatway Technology ndeye RF pamusoro pe fiber transmission chigadzirwa dhizaini imba uye fekitori kubvira 2004, ichipa FTTH CATV inogamuchira, RFoG ONU yeftth cable modem, satellite single/Twin/Quatro LNB RF pamusoro peGPON, Maviri/Mana satellite pamusoro pefiber imwe. link, 3224MHz Satellite Fiber Link, GPON uye GPON+, EoC, 1218MHz CATV optical transmitter uye optical node, kirasi yekutepfenyura AV/ASI/SDI fiber link.
