Chaw taws teeb OLT rau HFC network rau FTTH system

Lub Rau Hli 28, 2024, Greatway Technology tshaj tawm tso GRT319 Chaw Taws Teeb OLT khoom. GRT319 Chaw Taws Teeb OLT yog tsim los hloov HFC optical node, hloov lub xeem 100 meter coaxial cable tis network rau hauv 100 meter fiber ntau rau hauv tsev network, muab ob qho tib si DVB-C RF thiab GPON internet kev pabcuam rau txhua tus neeg siv CATV. Nrog Aluminium dej-pov thawj vaj tsev, GRT319 muaj ib qhov chaw nres nkoj fiber ntau qhov chaw 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 nrog GFH1000 FTTH CATV receiver, GRT319 Chaw Taws Teeb OLT khaws DVB-C STB nkaus xwb rau cov neeg siv CATV. Ua hauj lwm nrog GONU1100W FTTH ONU, GRT319 Chaw Taws Teeb OLT muab 2.5Gbps down streaming internet ntxiv rau CATV RF.

Node los ntawm node, GRT319 tuaj yeem pab CATV MSO hloov ib-txoj kev HFC CATV system mus rau ob-txoj kev FTTH system ntawm cov peev nyiaj pheej yig. 

Muaj ntau lab tus DVB-C STBs yogua haujlwm ntawm CATV system tam sim no. Peb yuav khaws lawv thaum qhia ntau yam kev pabcuam hauv internet. Chaw taws teeb OLT zoo dua thaum HFC rau FTTH.

Peb khaws 1550nm hnub qub-network rau txhua qhov kho qhov muag thiab qhia 10Gbps ntawm tib lub fiber ntau rau qhov kho qhov muag los ntawm WDM.Cov qub optical node yog hloov los ntawm ib qho Chaw Taws Teeb-OLT ntawm tib qhov chaw thiab tib lub zog.

Yav dhau los coaxial splitters thiab cables yog hloov los ntawm PLC splitters thiab FTTH cables los npog tag nrho cov neeg siv khoom.

Tej thaj chaw deb OLT txhawb 1 fiber ntau input thiab 1 fiber ntau tso zis.

Cov zis fiber ntau muaj 20dBm 1550nm teeb liab thiab ib qho GPON OLT rau ntau tshaj 256 tus neeg siv khoom. 

Ntawm txhua chav FTTH, muaj TV nkaus xwb lossis TV + Internet davhlau ya nyob twg xaiv.

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, Super Capacitor Roj teeb, GPON thiab GPON +, EoC, 1218MHz CATV optical transmitter thiab optical node, tshaj tawm hauv chav kawm AV / ASI / SDI fiber ntau txuas.
