G.fast yog tus qauv digital subscriber kab (DSL) txuj ci rau lub zos loops luv dua 500 m, nrog kev kawm lub hom phiaj ntawm 150 Mbit / s thiab 1 Gbit / s, nyob ntawm qhov tseeb lub voj ntev. Lub siab ceev tshaj plaws yog tiav dhau luv luv loops. G.fast systems sib txuas nrog fiber ntau cable, taw tes rau kev sib txuas ntawm qhov sib hloov ua fiber ntau rau tooj, thiab lub dav hlau (modem) hauv tus neeg siv khoom los hloov cov G.fast cov teeb liab rau Ethernet, WiFi, thiab lwm yam.
G. Ntsej muag Zej Zog (FTTdp = Fiber rau Lub Tooj Faib, FTTH = Fibre To Lub Tsev)
Muaj ntau tus neeg siv FTTH (Fiber rau lub tsev) kom xa ultra-broadband rau lawv cov neeg muas zaub. Txawm li cas los xij, qee qhov chaw ntawm cov neeg siv khoom muaj nuj nqis kim heev thiab tsis yooj yim mus cuag fiber ntau. Lub dag zog yuav tsum tau qhib cov hlua kab, khawb av yau thiab rewire tsev neeg nyias txawv nyias, ntxiv complexity thiab nqi. Tshiab G.fast technology ua qee yam ntawm cov nqi no rau cov khoom siv hluav taws xob los ntawm kev sib txuas ntawm FTTdp rau cov neeg siv khoom ntiag tug nyob qhov chaw nruab nrab / lub nplhaib khoov sib khi twb tau muaj lawm. Qhov no clears txoj kev kom txo qis nqi ultra-broadband delivery.
G.fast cia cov tswv lag luam coj cov kev ceev ntawm fiber ntau rau cov kab tooj liab. Kev tsim kho G.fast cov kev daws teeb meem thiab kev xa tawm tuaj yeem ua rau kev pab ultra-broadband rau txhua tus neeg siv.
FTTdp Architecture Zej Zog Saib
Kev tiv thaiv yuav tsum muab xam rau txhua qhov ntawm cov qauv ntsiab lus tooj. Qhov no suav nrog Chaw Teeb Khoom thiab Constomer Chaw nyob.
G.Xhia Txhim Kho Tas Raws Li Tawm Raws Li Tawm Raws Li Tiag - Cov nqi ntawm 1Gbps tau pom nyob rau hauv cov kev sib tw field
G.fast muab kev zoo li fiber ntau dhau lub hli dhau los ntawm kev siv cov qauv tooj liab uas twb muaj lawm. Nws kuj txo CAPEX (kev siv nyiaj txiag) los ntawm kev rho cov nqi ntawm fiber ntau rau txhua lub tsev thiab qhov chaw nyob. Qhov no tso cai rau txoj kev xa xov ultra-broadband mus rau qhov chaw uas cov chaw xa khoom siv hluav taws xob tsis yooj yim. Qhov no yuav pab tshem tawm qhov xav tau los nkag thiab rhuav cov vaj tse thiab vaj tse. G.fast self-installation yog ib qho txiaj ntsim zoo rau tus neeg muab kev pabcuam raws li tsis muaj tsheb thauj khoom siv los ua kom G.fast.
Nws yuav tsum raug sau tseg tias yuav muaj kev tshwm sim thaum uas "rov qab" hom ntawm G.fast mus rau VDSL2 / ADSL2, yuav siv tau, nyob ntawm qhov xwm ceev. Thaum tsim nyog (feem ntau ntawm cov loops ntev dua), tus tsav lub tsheb hloov ntawm G.fast qhia rau VDSL2, ADSL2 lossis SHDSL cov kev cai. Yog tias raug xaiv, lub Littelfuse overvoltage tiv thaiv ntaus ntawv yuav tau tshaj cov hom tshiab no.
