Kukho izigidi ze-DVB-C STBs ezisebenza kwinkqubo yangoku yeCATV HFC. Ukutshintsha zonke ezi DVB-C STBs kubiza imali eninzi kwaye ayisebenzi kuninzi lwabaqhubi beCATV. Okwangoku, kuyabiza ukusebenzisa imodem yentambo ebonelela ngenkonzo ye-intanethi ngaphezulu kwenkqubo yeHFC. Inkqubo ye-FTTH ye-1550nm yolwalekayo lukhetho olungabizi kakhulu kuzo zombini i-DVB-C RF kunye ne-Intanethi.Ubume obuqhelekileyo bothungelwano lwe-HFC lusekwe kuthungelwano lweenkwenkwezi. Iintambo zosinga ezizibonda ziqhagamshelwe ngokuthe ngqo kwiqela lee nodi zamehlo (umz.GWR1200) ukusukaGWT3500I-1550nm i-transmitter kwi-headend, kwaye i-node nganye ebonakalayo ikhonza amakhulu ababhalisile be-CATV ngentambo ye-coaxial.
I-Greatway Technology icebisa ukufakelaGRT319I-OLT ekude kwindawo ye-optical node yenkqubo ye-HFC ukugcina utyalo-mali lwentambo yefayibha yesiqu kunye nokugcina zonke iinkonzo ze-DVB-C RF. Sigcina i-1550nm star-network kwi-node nganye ye-optical kunye nokwazisa i-2.5Gbps okanye i-10Gbps kwi-fiber efanayo kwi-fiber optical node nge-WDM.
Indawo yangaphambili ye-optical node ithathelwa indawo yenyeGRT319Ukude-OLT kwindawo enye kunye nonikezelo lwamandla olufanayo. Izahlulo zangaphambili ze-coaxial kunye neentambo zitshintshwa ziqhekeza ze-PLC kunye neentambo ze-FTTH ukugubungela bonke ababhalisi.
GRT319I-OLT ekude iyilelwe ukuba ithathe indawo ye-HFC ye-optical node, iguqulela i-100 yemitha yokugqibela yonikezelo lwentambo yothungelwano kwi-fiber ye-100 yeemitha kuthungelwano lwasekhaya, inika zombini iinkonzo ze-intanethi ze-DVB-C RF kunye ne-GPON kubo bonke ababhalisi beCATV. Ngendlu yeAluminiyam engenamanzi,GRT319ine-fiber input port enye apho idatha ye-10Gbps kunye ne-1550nm CATV RF zisuka ngqo kwi-Headend yi-WDM, igcina utyalo-mali lwe-trunk fiber. I-GRT319 inemveliso yefiber enye edibanisa i-20dBm EDFA eyakhelwe-ngaphakathi kunye ne-port eyodwa ye-GPON OLT, exhasa ukuya kubabhalisi be-256 kwi-radius ye-100 yemitha yentambo ye-FTTH. Ukusebenza kunyeGFH1000-KUmmkeli we-FTTH CATV, i-GRT319 ekude i-OLT igcina i-DVB-C STB kuphela ishishini kubabhalisi beCATV. Ukusebenza kunyeI-GONU1100WI-FTTH ONU, i-GRT319 i-OLT ekude ibonelela nge-2.5Gbps ezantsi ustrimisho lwe-intanethi ngaphandle kwe-CATV RF.
I-node nge-node,GRT319inokunceda iCATV MSO iguqule indlela enye yeHFC CATV inkqubo ibe yinkqubo yeFTTH eneendlela ezimbini kuhlahlo lwabiwo-mali olufikelelekayo.
