GPON Internet yog dab tsi?

GPON Internet yog ib qho khoom siv kho qhov muag kis tau tus mob uas tso cai rau koj los txuas cov neeg siv khoom hauv Is Taws Nem nrog kev kub ceev thiab kev ntseeg siab. Hauv tsab xov xwm no peb yuav qhia koj tias GPON Internet yog dab tsi, nws ua haujlwm li cas, nws muaj txiaj ntsig zoo li cas thiab txuas nws li cas.

GPON Internet yog dab tsi?

GPON (Gigabit Passive Optical Network) yog lub network passive optical uas siv cov khoom siv kho qhov muag los xa cov ntaub ntawv ntawm lub chaw haujlwm hauv nruab nrab (OLT) thiab cov khoom siv (ONT). GPON Internet yog hais txog ITU-T G.984 tus qauv, uas txhais cov kev txwv thiab cov yam ntxwv ntawm lub network zoo li no.

GPON internet muab cov ntaub ntawv siab hloov ceev - mus txog 2,5 Gbit / s nyob rau hauv cov kev taw qhia ntawm OLT rau ONT thiab mus txog 1,25 Gbit / s nyob rau hauv lub opposite direction. Tsis tas li ntawd, GPON Internet txhawb ntau hom kev khiav tsheb, xws li Is Taws Nem, xov tooj, TV, saib video thiab lwm yam.

GPON Internet ua haujlwm li cas?

GPON Internet ua haujlwm ntawm lub hauv paus ntsiab lus ntawm lub sij hawm faib (TDM) thiab wavelength division (WDM). TDM txhais tau hais tias cov ntaub ntawv los ntawm cov neeg siv khoom sib txawv raug xa mus rau tib lub sijhawm kho qhov muag ntawm lub sijhawm sib txawv, thiab WDM txhais tau hais tias cov ntaub ntawv los ntawm ntau hom kev khiav tsheb tau kis mus rau ntau lub wavelengths.

GPON Internet muaj peb lub ntsiab lus tseem ceeb:

• OLT (Optical Line Terminal) yog ib qho khoom siv hauv nruab nrab uas txuas mus rau tus neeg muab kev pabcuam hauv Is Taws Nem thiab tswj cov ntaub ntawv hloov pauv ntawm cov khoom siv kho qhov muag thiab cov neeg siv khoom.
• ONT (Optical Network Terminal) yog ib qho khoom siv uas txuas mus rau fiber ntau optical thiab hloov kho qhov muag teeb liab rau hauv hluav taws xob teeb liab, thiab tseem muab cov khoom sib txuas rau kev sib txuas ntau yam xws li khoos phis tawj, xov tooj, TV thiab lwm yam.
• ODN (Optical Distribution Network) yog ib qho khoom siv kho qhov muag uas txuas OLT thiab ONT. ODN tuaj yeem suav nrog ntau yam khoom siv kho qhov muag xws li splitters, connectors, adapters, thiab lwm yam.

Schematically, GPON Internet tuaj yeem sawv cev raws li hauv qab no:

Qhov zoo ntawm GPON

Kev sib txuas rau Is Taws Nem ntawm GPON muaj ntau qhov zoo dua lwm yam thev naus laus zis xws li ADSL, VDSL, Ethernet lossis DOCSIS. Nov yog qee qhov ntawm lawv:

• Kev kub ceev. GPON tso cai rau koj kom tau txais Internet ceev txog li 2,5 Gbit / s, uas yog ob peb zaug siab tshaj qhov ceev ntawm lwm yam technologies. Qhov no txhais tau tias koj tuaj yeem saib cov yeeb yaj kiab siab, ua si hauv online, rub tawm cov ntaub ntawv loj thiab siv lwm cov kev pabcuam hauv Is Taws Nem yam tsis muaj lag luam lossis cuam tshuam.
• Kev ntseeg tau. GPON siv optical cable uas tsis raug rau electromagnetic cuam tshuam, corrosion, overheating lossis mechanical puas. Tsis tas li ntawd, passive optical network tsis muaj cov ntsiab lus uas tuaj yeem ua tsis tau lossis yuav tsum tau hloov pauv. Qhov no ua kom muaj kev ruaj ntseg thiab kev sib txuas lus zoo hauv txhua qhov xwm txheej.
• Kev lag luam. GPON tso cai rau koj los txo tus nqi ntawm kev sib txuas thiab kev tswj xyuas lub network, vim nws tsis tas yuav muaj cov khoom siv ntxiv, hluav taws xob lossis cov neeg ua haujlwm. Tsis tas li ntawd, GPON tso cai rau koj kom tau txais ntau yam kev sib txuas lus hauv ib lub cable, uas txo cov xov hlau thiab cov sockets hauv chav tsev.
• Ntau yam. GPON txhawb ntau yam kev cai thiab cov qauv kev sib kis, xws li IP, ATM, Ethernet, TDM thiab lwm yam. Qhov no tso cai rau koj txuas txhua yam khoom siv rau lub network thiab siv cov kev pabcuam kev sib txuas lus, xws li Is Taws Nem, TV, xov tooj, kev soj ntsuam video, intercom thiab lwm yam.

Disadvantages ntawm GPON

• Tsawg bandwidth. Txawm hais tias GPON muab kev kub ceev hauv Internet, nws tsis tau lees tias, tab sis nyob ntawm tus naj npawb ntawm cov neeg siv khoom txuas nrog ib qho optical splitter. Yog tias muaj ntau tus neeg siv khoom, lub network bandwidth yuav muab faib nruab nrab ntawm lawv thiab Internet ceev yuav txo. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv ib tus neeg muab kev pabcuam uas tswj cov naj npawb ntawm cov neeg siv khoom ib ntus thiab muab cov bandwidth txaus rau txhua tus neeg siv khoom.
• Kev ruaj ntseg tsawg. GPON siv ib qho khoom siv kho qhov muag los xa cov ntaub ntawv los ntawm tus kws kho mob mus rau cov neeg siv khoom txuas nrog tib lub splitter. Qhov no txhais tau hais tias txhua tus neeg siv tau txais tib lub teeb liab, uas tuaj yeem cuam tshuam lossis hloov kho los ntawm cov neeg tawm tsam. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau xaiv ib tug neeg muab kev pab uas siv ntau yam encryption thiab authentication txoj kev los tiv thaiv koj cov ntaub ntawv los ntawm tsis tau tso cai.
• Tus nqi siab. GPON xav tau kev teeb tsa ntawm cov cuab yeej tshwj xeeb, uas yog kim heev. Qhov no siv rau ob qho tib si OLT nyob ntawm tus kws kho mob thiab ONT nyob hauv cov neeg siv khoom lub tsev. Ntxiv mus, tus nqi ntawm optical cable kuj tseem siab dua tus nqi ntawm tooj liab cable. Yog li ntawd, tariffs rau kev txuas mus rau GPON tej zaum yuav siab dua rau kev txuas mus rau lwm yam technologies.

Yuav txuas GPON Internet li cas?

Txhawm rau txuas GPON Internet, koj yuav tsum ua tiav cov kauj ruam hauv qab no:

• Hu rau tus kws kho mob hauv Internet uas muab kev pabcuam GPON Internet hauv koj cheeb tsam thiab kos npe rau daim ntawv cog lus txuas. (Piv txwv li Briz)
• Xaiv ib txoj kev npaj uas haum koj cov kev xav tau thiab pob nyiaj siv. Feem ntau, tariffs nyob ntawm seb qhov ceev, ntim thiab hom tsheb, nrog rau kev muaj cov kev pabcuam ntxiv xws li xov tooj, TV thiab lwm yam.
• Tau txais ONT tus neeg siv khoom siv los ntawm koj tus kws kho mob hauv Is Taws Nem, uas yuav tsum tau txuas nrog cov khoom siv kho qhov muag uas tus kws kho mob yuav txuas mus rau koj lub tsev lossis chav tsev. Ib qho ONT tuaj yeem yog sab hauv lossis sab nraud, nyob ntawm seb hom fiber ntau optical thiab qhov chaw teeb tsa.
• Txuas rau ONT ntau yam khoom siv uas koj xav siv los nkag rau Is Taws Nem, xws li khoos phis tawj, xov tooj, TV thiab lwm yam. Txhawm rau ua qhov no, koj yuav xav tau Ethernet cables, kab xov tooj, coaxial cables, lossis txuas wireless.
• Configure chaw
