Hauv kev sib txuas lus Network niaj hnub no, PassiveOptical Network (PON) thev naus laus zis tau maj mam tuav txoj haujlwm tseem ceeb hauv kev sib txuas lus tseem ceeb nrog nws qhov zoo ntawm kev kub ceev, kev ncua deb thiab tsis muaj suab nrov.Ntawm lawv, GPON, XG-PON thiab XGS-PON yog cov kev txhawj xeeb tshaj plaws ntawm kev siv tshuab kho qhov muag.Lawv muaj lawv tus yam ntxwv thiab tau siv dav hauv cov xwm txheej sib txawv.Kab lus no tshuaj xyuas qhov sib txawv tseem ceeb ntawm peb lub thev naus laus zis hauv kev nthuav dav los pab cov neeg nyeem nkag siab zoo dua lawv cov yam ntxwv thiab daim ntawv thov scenarios.
GPON, lub npe tag nrho Gigabit-CapablePassive OpticalNetwork, yog ib qho kev siv hluav taws xob siv hluav taws xob siv hluav taws xob ua ntej tshaj tawm los ntawm FSAN lub koom haum hauv xyoo 2002. Tom qab ob peb xyoos ntawm txoj kev loj hlob, ITU-T officially standardized nws nyob rau hauv 2003. GPON technology yog tsuas yog rau kev nkag tau network kev lag luam, uas muaj peev xwm. muab cov ntaub ntawv ceev thiab muaj peev xwm loj, lub suab thiab video kev pabcuam rau cov tsev neeg thiab cov lag luam.
GPON technology nta yog raws li nram no:
1. Ceev: downstream kis tus nqi yog 2.488Gbps, ntws ntws tus nqi yog 1.244Gbps.
2. Shunt ratio: 1:16/32/64.
3. Kev sib kis nrug: qhov siab tshaj plaws kis tau tus mob yog 20km.
4. Encapsulation hom: Siv GEM (GEM Encapsulation Method) encapsulation hom.
5. Kev tiv thaiv mechanism: Txais 1 + 1 lossis 1: 1 passive tiv thaiv kev hloov tshuab.
XG-PON, lub npe tag nrho ntawm 10Gigabit-CapablePassive OpticalNetwork, yog tiam tom ntej ntawm GPON thev naus laus zis, tseem hu ua lwm tiam passive optical network (NG-PON).Piv nrog GPON, XG-PON muaj kev txhim kho tseem ceeb hauv kev ceev, shunt piv thiab kis tau tus mob.
XG-PON technology nta yog raws li nram no:
1. Ceev: Downlink kis tus nqi yog 10.3125Gbps, uplink kis tus nqi yog 2.5Gbps (uplink kuj yuav upgraded rau 10 GBPS).
2. Shunt ratio: 1:32/64/128.
3. Kev sib kis nrug: qhov siab tshaj plaws kis tau tus mob yog 20km.
4. Ntim hom: Siv GEM / 10GEM pob hom.
5.Kev tiv thaiv mechanism: Txais 1 + 1 lossis 1: 1 passive tiv thaiv kev hloov tshuab.
XGS-PON, lub npe hu ua 10GigabitSymmetric Passive OpticalNetwork, yog qhov sib xyaw ua ke ntawm XG-PON, tsim los muab kev pabcuam dav dav nrog cov nqi nce thiab nqis qis.Piv nrog XG-PON, XGS-PON muaj qhov nce ntxiv hauv qhov nrawm nrawm.
XGS-PON technology nta yog raws li nram no:
1. Ceev: Tus nqi xa mus rau hauv qab yog 10.3125Gbps, tus nqi xa mus rau sab saud yog 10 GBPS.
2. Shunt ratio: 1:32/64/128.
3. Kev sib kis nrug: qhov siab tshaj plaws kis tau tus mob yog 20km.
4. Ntim hom: Siv GEM / 10GEM pob hom.
5. Kev tiv thaiv mechanism: Txais 1 + 1 lossis 1: 1 passive tiv thaiv kev hloov tshuab.
Xaus: GPON, XG-PON thiab XGS-PON yog peb qhov tseem ceeb passive optical network technologies.Lawv muaj qhov sib txawv hauv qhov nrawm, qhov sib piv, qhov sib kis, thiab lwm yam, kom tau raws li qhov xav tau ntawm cov ntawv thov sib txawv.
Tshwj xeeb: GPON feem ntau yog rau kev nkag mus rau kev lag luam network, muab cov ntaub ntawv ceev ceev, muaj peev xwm loj, suab thiab video thiab lwm yam kev pabcuam;XG-PON yog qhov hloov kho dua tshiab ntawm GPON, nrog kev nrawm dua thiab hloov pauv hloov pauv ntau dua.XGS-PON hais txog qhov sib luag ntawm tus nqi nce thiab nqis qis thiab tsim nyog rau kev sib koom ua phooj ywg sib koom ua ke.Kev nkag siab txog qhov sib txawv tseem ceeb ntawm peb lub thev naus laus zis no pab peb xaiv txoj cai kho qhov muag network daws teeb meem rau cov xwm txheej sib txawv.
