Kunezigidi zama-DVB-C STB asebenza ohlelweni lwamanje lwe-CATV HFC. Ukushintsha wonke lawa ma-DVB-C STB kubiza imali enkulu futhi akusebenzi kubasebenzisi abaningi be-CATV. Okwamanje, kuyabiza ukusebenzisa imodemu yekhebula ehlinzeka ngesevisi ye-inthanethi ngohlelo lwe-HFC. I-1550nm imbondela yesistimu ye-FTTH iyinketho engabizi kukho kokubili i-DVB-C RF ne-inthanethi.Isakhiwo senethiwekhi ye-HFC esijwayelekile sisekelwe kunethiwekhi yenkanyezi. Izintambo ze-trunk fibre zixhunywe ngqo enanini lama-optical node (isbGWR1200) kusukaI-GWT3500I-transmitter engu-1550nm esihlokweni, futhi inodi ngayinye yokubona isebenzela amakhulukhulu ababhalisile be-CATV ngekhebula eliqinile.
I-Greatway Technology iphakamisa ukufakaGRT319I-OLT ekude endaweni ye-optical node yohlelo lwe-HFC ukulondoloza ukutshalwa kwezimali kwekhebula le-trunk fibre nokugcina zonke izinsiza ze-DVB-C RF. Sigcina inethiwekhi yenkanyezi engu-1550nm endaweni ngayinye yokubona futhi sethula i-2.5Gbps noma i-10Gbps ku-fibre efanayo ku-fiber optical node nge-WDM.
I-optical node yangaphambili ithathelwa indawo eyodwaGRT319I-Remote-OLT endaweni efanayo kanye nokunikezwa kwamandla okufanayo. Izihlukanisi zangaphambili ze-coaxial nezintambo zithathelwa indawo yizihlukanisi ze-PLC nezintambo ze-FTTH ukuze zimboze bonke ababhalisile.
GRT319I-OLT ekude iklanyelwe ukuvala indawo ye-HFC optical node, iguqule inethiwekhi yokugcina ye-coaxial cable yamamitha ayi-100 ibe yifayibha yokugcina engamamitha ayi-100 kunethiwekhi yasekhaya, inikezela ngezinsizakalo ze-inthanethi ze-DVB-C RF kanye ne-GPON kubo bonke ababhalisile be-CATV. Ngezindlu ze-Aluminium ezingenamanzi,GRT319inembobo yokufaka eyodwa yefiber lapho idatha engu-10Gbps kanye ne-1550nm CATV RF zisuka ngokuqondile ku-Headend by WDM, konga utshalomali lwe-trunk fiber. I-GRT319 inokukhishwa kwefayibha eyodwa ehlanganisa eyakhelwe ngaphakathi engu-20dBm EDFA kanye nembobo eyodwa ye-GPON OLT, esekela ababhalisile abangafika kwabangu-256 kububanzi bentambo ye-FTTH engamamitha ayi-100. Ukusebenza ngeI-GFH1000-KIsamukeli se-FTTH CATV, i-GRT319 Remote OLT igcina i-DVB-C STB ibhizinisi kuphela kwababhalisile be-CATV. Ukusebenza ngeI-GONU1100WI-FTTH ONU, GRT319 Remote OLT inikeza i-inthanethi yokusakaza phansi engu-2.5Gbps ngaphandle kwe-CATV RF.
I-Node nge-node,GRT319ingasiza i-CATV MSO ekuguquleni uhlelo lwe-HFC CATV lwendlela eyodwa lube uhlelo lwe-FTTH olunezindlela ezimbili ngesabelomali esithengekayo.
