Qhov zoo thiab qhov tsis zoo ntawm XGPON thiab GPON

XGPON thiab GPON txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo thiab tsim nyog rau cov xwm txheej sib txawv.

Qhov zoo ntawm XGPON suav nrog:

1.Kev kis tau tus mob siab dua: XGPON muab txog 10 Gbps downlink bandwidth thiab 2.5 Gbps uplink bandwidth, haum rau daim ntawv thov scenarios nrog siab thov rau high-ceev cov ntaub ntawv kis tau tus mob.

2.Advanced modulation thev naus laus zis: XGPON siv cov thev naus laus zis thev naus laus zis xws li QAM-128 thiab QPSK txhawm rau txhim kho qhov zoo thiab qhov deb ntawm cov teeb liab kis tau tus mob.

3.Wider network kev pab them nqi: Qhov sib cais ntawm XGPON tuaj yeem ncav cuag 1: 128 lossis siab dua, tso cai rau nws npog thaj tsam dav dua.

Txawm li cas los xij, XGPON kuj muaj qee qhov tsis zoo:

1.Cov nqi siab dua: Vim tias XGPON siv cov thev naus laus zis ntau dua thiab cov cuab yeej siv ntau dua, nws cov nqi kuj tseem siab thiab tej zaum yuav tsis tsim nyog rau cov nqi siv hluav taws xob.

Qhov zoo ntawmGPONfeem ntau suav nrog:

1.Kev kub ceev thiab siab bandwidth:GPON tuaj yeem muab tus nqi sib kis ntawm 1.25 Gbps (kev taw qhia downstream) thiab 2.5 Gbps (kev coj mus nce toj) kom tau raws li cov neeg siv cov kev xav tau rau kev sib txuas ceev ceev.

2.Ntev kis tau tus mob:Optical fiber kis tau tus mob tso cai rau cov teeb liab kis tau tus mob mus txog kaum kilometers, ua tau raws li ib tug ntau yam ntawm network topology yuav tsum tau.

3.Symmetric thiab asymmetric kis tau tus mob:GPON txhawb nqa symmetric thiab asymmetric kis tau tus mob, uas yog, lub uplink thiab downlink kis tau tus mob yuav txawv, cia lub network kom zoo dua hloov mus rau cov kev xav tau ntawm cov neeg siv sib txawv thiab kev siv.

4.Distributed architecture:GPON txais yuav ib qho point-to-multipoint optical fiber ntau kis tau tus mob architecture thiab txuas kho qhov muag kab terminals (OLT) thiab ntau qhov chaw kho qhov muag network (ONUs) los ntawm ib kab kho qhov muag fiber ntau, txhim kho kev siv cov peev txheej network.

5.Tus nqi tag nrho ntawm cov cuab yeej yog qis dua:Txij li thaum lub uplink tus nqi kuj qis, tus nqi ntawm ONU cov khoom xa tuaj (xws li lasers) kuj qis, yog li tag nrho cov nqi ntawm cov khoom siv tsawg.

Qhov tsis zoo ntawm GPON yog tias nws qeeb dua XGPON thiab tej zaum yuav tsis haum rau daim ntawv thov scenarios uas xav tau ultra-high-speed cov ntaub ntawv xa mus.

Hauv cov ntsiab lus, XGPON thiab GPON txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo thiab tsim nyog rau cov xwm txheej sib txawv.XGPON yog qhov tsim nyog rau daim ntawv thov scenarios nrog kev thov siab rau kev xa cov ntaub ntawv ceev ceev, xws li cov lag luam loj, cov chaw zov me nyuam, thiab lwm yam .;thaum GPON yog qhov tsim nyog rau cov xwm txheej nkag tau yooj yim ntawm tsev thiab kev lag luam tes hauj lwm kom tau raws li cov kev xav tau niaj hnub network.Thaum xaiv cov cuab yeej siv network, yam xws li kev xav tau, tus nqi, thiab cov kev xav tau yuav tsum raug txiav txim siab.
