Muaj ntau lab tus DVB-C STBs ua haujlwm ntawm CATV HFC system tam sim no. Hloov tag nrho cov DVB-C STBs no raug nqi nyiaj ntau thiab nws tsis zoo rau feem ntau CATV tus tswv. Lub caij no, nws kim heev rau siv cable modem muab kev pabcuam hauv internet hla HFC system. 1550nm overlay FTTH system yog qhov kev xaiv zoo rau ob qho tib si DVB-C RF thiab Internet.Tus qauv HFC network yog raws li lub hnub qub-network. Lub cev fiber ntau cables txuas ncaj qha mus rau ntau qhov chaw kho qhov muag (xws liGWR 1200) los ntawmTSI 35001550nm transmitter nyob rau hauv headend, thiab txhua qhov kho qhov muag node pab ntau pua ntawm CATV cov neeg siv khoom tshaj coaxial cable.
Greatway Technology qhia kev txhim khoGRT319tej thaj chaw deb OLT ntawm qhov chaw kho qhov muag ntawm HFC qhov system kom txuag tau lub cev fiber ntau cable peev thiab tswj txhua qhov kev pabcuam DVB-C RF. Peb khaws 1550nm hnub qub-network rau txhua qhov kho qhov muag thiab qhia 2.5Gbps lossis 10Gbps ntawm tib lub fiber ntau rau qhov kho qhov muag fiber ntau los ntawm WDM.
Cov qub optical node yog hloov los ntawm ib qhoGRT319Chaw taws teeb-OLT ntawm tib qhov chaw thiab tib lub hwj chim. Yav dhau los coaxial splitters thiab cables yog hloov los ntawm PLC splitters thiab FTTH cables los npog tag nrho cov neeg siv khoom.
GRT319Tej thaj chaw deb OLT yog tsim los hloov HFC kho qhov muag node, hloov lub xeem 100 meter coaxial cable faib network mus rau hauv lub xeem 100 meter fiber ntau rau lub tsev network, muab ob DVB-C RF thiab GPON internet kev pab cuam rau tag nrho cov neeg siv CATV. Nrog Aluminium Dej-pov thawj vaj tsev,GRT319muaj ib qhov chaw nres nkoj fiber ntau qhov twg 10Gbps cov ntaub ntawv thiab 1550nm CATV RF ncaj qha los ntawm Headend los ntawm WDM, txuag lub cev fiber ntau peev. GRT319 muaj ib tug fiber ntau tso zis integrating built-in 20dBm EDFA thiab ib qho chaw nres nkoj GPON OLT, txhawb mus txog rau 256 neeg rau hauv lub vojvoog ntawm 100 meter FTTH cable. Ua haujlwm nrogGFH1000-KFTTH CATV txais, GRT319 Chaw Taws Teeb OLT khaws DVB-C STB tsuas yog ua lag luam rau CATV cov neeg siv khoom. Ua haujlwm nrogGONU 1100 WFTTH ONU, GRT319 Chaw Taws Teeb OLT muab 2.5Gbps down streaming internet ntxiv rau CATV RF.
Node ntawm node,GRT319tuaj yeem pab CATV MSO hloov ib-txoj kev HFC CATV system mus rau ob-txoj kev FTTH system ntawm tus nqi pheej yig.
