Cov ntsiab cai thiab kev siv ntawm XPON Technology

8 PON Chaw nres nkoj EPON OLT CT-GEPON3840

XPON cov ntaub ntawv encapsulation thiab tsom xam

Hauv XPON system, cov ntaub ntawv encapsulation yog hais txog cov txheej txheem ntawm kev ntxiv cov ntaub ntawv xws li headers thiab trailers rau cov ntaub ntawv units kis ntawm OLT thiab ONU.Cov ntaub ntawv no yog siv los txheeb xyuas hom, hom phiaj thiab lwm yam khoom ntawm cov ntaub ntawv chav tsev kom qhov kawg tau txais tuaj yeem txheeb xyuas thiab ua cov ntaub ntawv.Cov ntaub ntawv parsing yog cov txheej txheem uas qhov kawg tau txais cov ntaub ntawv rov qab mus rau nws cov qauv qub raws li cov ntaub ntawv encapsulation.

XPON cov txheej txheem xa cov ntaub ntawv

Hauv XPON system, cov txheej txheem xa cov ntaub ntawv feem ntau suav nrog cov kauj ruam hauv qab no:

1. Lub OLT encapsulates cov ntaub ntawv rau hauv optical signals thiab xa mus rau passive optical splitter los ntawm cov kho qhov muag cable.

2. Lub passive optical splitter faib cov teeb liab kho qhov muag mus rau qhov sib thooj ONU.

3. Tom qab tau txais cov teeb liab kho qhov muag, ONU ua kev hloov kho qhov muag mus rau hluav taws xob thiab rho tawm cov ntaub ntawv.

4. ONU txiav txim siab qhov chaw ntawm cov ntaub ntawv raws li cov ntaub ntawv hauv cov ntaub ntawv encapsulation, thiab xa cov ntaub ntawv mus rau cov khoom siv sib txuas lossis cov neeg siv.

5. Lub tshuab txais lossis cov neeg siv tshuaj xyuas thiab ua cov ntaub ntawv tom qab tau txais.

XPON kev ruaj ntseg mechanism

Cov teeb meem kev ruaj ntseg ntsib los ntawm XPON feem ntau suav nrog kev nkag mus tsis raug cai, kev tawm tsam tsis zoo thiab cov ntaub ntawv eavesdropping.Txhawm rau daws cov teeb meem no, XPON system txais ntau yam kev ruaj ntseg mechanisms:

1. Authentication mechanism: Ua pov thawj tus kheej ntawm ONU kom ntseeg tau tias tsuas yog cov neeg siv raug cai tuaj yeem nkag mus rau hauv lub network.

2. Encryption mechanism: Encrypt cov ntaub ntawv xa mus los tiv thaiv cov ntaub ntawv los ntawm kev eavesdropped los yog tampered.

3. Kev tswj xyuas kev nkag mus: txwv cov neeg siv txoj cai nkag mus los tiv thaiv cov neeg siv tsis raug cai los ntawm kev siv cov peev txheej hauv network.

4. Kev saib xyuas thiab ceeb toom: Saib xyuas cov xwm txheej hauv lub network hauv lub sijhawm tiag tiag, lub tswb nyob rau lub sijhawm thaum pom cov xwm txheej txawv txav, thiab ua raws li kev ntsuas kev nyab xeeb.

Kev siv XPON hauv tsev network

XPON thev naus laus zis muaj kev thov dav dav hauv kev sib txuas hauv tsev.Ua ntej tshaj plaws, XPON tuaj yeem ua tiav kev siv Internet ceev kom tau raws li cov kev xav tau ntawm cov neeg siv hauv tsev rau kev sib txuas ceev;Qhov thib ob, XPON tsis tas yuav muaj cov kab hluav taws xob sab hauv tsev, uas txo cov nqi kev teeb tsa thiab kev saib xyuas ntawm cov tsev sib txuas hauv tsev;Thaum kawg, XPON tuaj yeem paub txog kev sib koom ua ke ntawm ntau lub network, kev sib koom tes hauv xov tooj, TVs thiab khoos phis tawj.Lub network tau koom ua ke rau hauv tib lub network los pab txhawb cov neeg siv khoom siv thiab kev tswj hwm.
