Kev khiav dej num ntawm ONT thiab OLT hauv GPON Network
Gigabit passive optical network (GPON) yog qhov sib kis-ntau-qhov muaj peev xwm nkag mus rau cov neeg siv muab cov neeg siv kawg nrog lub peev xwm los sib txuam ntau cov kev pabcuam mus rau ib tus neeg thauj khoom fiber ntau. Txhawm rau paub cov thev naus laus zis no, ntau cov cuab yeej siv tau los txhawb nqa lub network, xws li optical splitter, ONT, OLT, thiab lwm yam hauv tsab xov xwm no, peb yuav tsuas yog tham txog cov haujlwm ntawm ONT thiab OLT hauv GPON network.
Kev tso cai ntawm ONT thiab OLT
Optical network davhlau ya nyob twg (ONT) yog qhov khoos phis tawm uas txuas rau qhov txiav qhov chaw nrog qhov kho qhov muag cable. Nws yog siv thaum kawg tus neeg siv lub premise coj mus cuag rau PON network ntawm ib sab thiab interface nrog cov neeg siv ntawm lwm sab. Cov ntaub ntawv tau txais los ntawm cov neeg siv khoom kawg yog xa, sib sau thiab ua kom zoo los ntawm ONT mus rau cov dej ntws los ntawm OLT. ONT tseem muaj lub npe hu ua optical network unit (ONU). ONT yog ITU-T sij hawm, thaum ONU yog IEEE lus. Nkawd ob leeg xa mus rau cov neeg siv sab khoom siv hauv GPON network. Ib qho sib txawv me me ntawm lawv tej zaum yuav yog qhov chaw thov. ONU tuaj yeem ua haujlwm nyob rau qhov sib txawv kub thiab huab cua.
Optical line davhlau ya nyob twg (OLT) yog qhov kawg ntawm cov cuab yeej kho vajtse nyob hauv lub hauv paus chaw ua haujlwm ntawm PON network. Nws cov haujlwm yooj yim yog tswj cov lus qhia hauv lub ntab hauv qhov xa tawm ntawm cov xa hluav taws xob (ODN) kom mus rau ob qho tib si. OLT hloov cov cim teeb liab uas siv los ntawm cov kev pabcuam fiber ntau (FiOS) rau ntau zaus thiab thav duab uas siv los ntawm PON system. Ntxiv rau, nws tswj fwm cov sib txuam ntawm ONT hloov dua siab tshiab pab kiag li lawm. Muaj ob lub ntab lus qhia rau OLT system. Ib qho yog qhov kev coj hauv pem hauv ntej los faib cov ntau hom ntawm cov ntaub ntawv thiab lub suab khiav lag luam los ntawm cov neeg siv. Lwm qhov yog cov kev nqes hauv qab uas tau txais cov ntaub ntawv, lub suab thiab cov vis dis aus ntawm metro network los yog los ntawm kev sib koom tes ntev thiab xa nws mus rau txhua ONT modules ntawm ODN.
Yuav ua li cas Ntxiv lossis Rho Tawm ONT ntawm OLT?
Yog tias lo lus zais ntawm ONT tau, koj tuaj yeem khiav ONT ntxiv kev hais kom ntxiv rau ONT offline. Txawm li cas los xij, yog tias lo lus zais tsis paub, koj tuaj yeem khiav qhov chaw nres nkoj portt ont-auto-nrhiav cov lus txib hauv GPON hom los pab kom ONT nrhiav-ua haujlwm ntawm GPON chaw nres nkoj, thiab tom qab ntawd khiav ONT tshawb kom paub meej kom paub meej tias ONT. Thaum cov ONT ntxiv, koj yuav tsum khiav cov zaub ONT info hais kom ua kom pom cov xwm txheej ntawm ONT tam sim no. Yog tias tus tswj chij dhia,
Thaum koj xav rho tawm ONT ntawm OLT, thov siv cov lus txib kom tshem tawm. Tom qab ntawd ONT cov ntaub ntawv teeb tsa raug muab tshem tawm nrog kev tshem ntawm ONT thiab online ONT raug yuam offline. ONT tsis tuaj yeem raug muab tua tawm thaum nws tau teeb tsa nrog lwm cov kev pabcuam. Koj yuav tsum unbind cov kev pab cuam ua ntej ua ntej rho tawm ONT.
Yuav daws cov teeb meem ONT?
Txhawm rau daws teeb meem ntawm ONT, koj yuav tsum nco ntsoov tias cov kauj ruam tseem ceeb tshaj plaws yog txuas koj lub khoos phis tawm ncaj qha mus rau ONT kom pom tias qhov teeb meem ploj mus. Koj tuaj yeem siv Ethernet cable rau kev txuas. Yog tias qhov teeb meem tseem muaj, koj tuaj yeem txuas ONT lub hwj huam mov kom tshem tau nws cov cache hauv. Yog tias lub network tsis tuaj yeem rov qab tau tom qab cov qauv saum toj no, tej zaum koj yuav tsum tau nrog cov kws tshaj lij pabcuam kev pabcuam.
Xaus
ONT thiab OLT yog cov khoom tseem ceeb uas tsis tseem ceeb hauv GPON qhov system network. Yog tias koj tab tom xav yuav cov khoom siv ONT lossis OLT, FOCC yog qhov chaw zoo. Cov khoom siv sib txawv ONT thiab OLT muab nrog kev sib koom ua ke siab, yoog raws kev hloov pauv thiab kev ntseeg siab kom tau raws li txhua yam koj xav tau.
