Yintoni i-xgs-pon? I-xgs-pon i-pon i-teon kunye ne-GEN kunye ne-xG-pon?

1. Yintoni i-xgs-pon?

ZombiniI-XG-PONkwaye i-xgs-pon yeyoGpnuthotho. Ukusuka kwimephu yendlela yobugcisa, i-xgs-pon yiveration yetekhnoloji ye-xg-pon.
Zombini i-xg-pon kunye ne-xgs-pon yi-10G pon, umahluko omkhulu: I-xg-pon yi-pon ye-asymmetric, i-punlink / i-Pollink ye-Pon yi-2.5G / i-10G / i-10g / i-10g / i-10g / i-10g / i-10g / i-10g / i-10g / i-10g / i-10g / i-10G; I-xgs-pon yi-Symmetric Pon, inqanaba le-pullink / eliphantsi le-pon port i-10G / i-10G.
Itekhnoloji ye-Pon ye-Pon isetyenziswe ngoku yi-Gon kunye ne-XG-PON, zombini eziyi-asymmetric pon. Kuba i-upstream yomsebenzisi / i-DownLink yedatha i-Asymmetrical, ithatha isixeko esithile se-tier singumzekelo, itrafikhi yendlela ye-oltream ye-oltre yi-22% kuphela yetrafikhi. Ke ngoko, iimpawu zobugcisa ze-Asymmetric Pon zinxulumene neemfuno zabasebenzisi. umdlalo. Okubaluleke ngakumbi, inqanaba eliphezulu le-asymmetric pon liphantsi, iindleko zokuthumela izinto ezifana nee-lasers ezifana ne-AUS iphantsi, kwaye ixabiso lezixhobo liphantsi.
Nangona kunjalo, iimfuno zabasebenzisi ziyahluka. Ukunyuka kweenkonzo zosasazo eziphilayo kunye nevidiyo, kukho iimeko ezininzi kwaye zininzi apho abasebenzisi banikela ingqalelo ngakumbi kwi-bandwidth evuthayo. Imigca ezinikezelweyo ezinikezelweyo kufuneka ibonelele nge-symmetrical uplink / i-downlring. La mashishini akhuthaza imfuno ye-xgs-pon.

I-2. Ukudibana kwe-xugs-pon, i-xg-pon kunye ne-GEN

I-xgs-pon yindalo ye-Gon kunye ne-XG-PON, kwaye ixhasa ukufikelela okuxubeneyo kweentlobo ezintathu ze-Otus: GEN, i-XG-POP-POP-POP-POP.

2.1 Ukudibana kwe-xgs-pon kunye ne-xg-pon

NjengoXg-Pon, i-Donlink ye-xgs-pon yamkela indlela yosasazo, kwaye i-Uplink yamkela i-TDMA.
Ukusukela ukuba i-downstrength wavelength kunye ne-DowWonatream Inqanaba le-xgs-pon kunye ne-xg-pon iyafana, i-Donnstream ye-xus-pon i-on-the, i-xon ye-on) ye-odn (i-chanlical) ye-odn (i-xg-pon kunye ne-xgs-pon) I-OUT, nganye inyulu i-ouoses ukufumana eyalo isibonisi kwaye ilahla eminye imiqondiso.
I-pullink ye-xgs-pon yenza idatha yosulelo lwedatha ngokwexesha, kwaye i-Ofu ithumela idatha ngexesha le-slots evunyelwe yi-olt. I-OLT esebenzayo nge-Slots ye-slots ngokweemfuno zeTrafikhi ye-Outus kunye nohlobo lwe-onu (yi-xg-pon okanye i-xgs-pon?). Ngexesha le-slot eyabelwe i-XG-PON Onu, inqanaba lokuhambisa idatha yi-2.5pbps; Ngexesha le-slot olwelwe i-xgs-pon nu, inqanaba lokuhambisa idatha liyi-10bbps.
Ingabonwa ukuba i-xgs-pon ngokwemvelo ixhasa ukufikelela okuxubeneyo kunye neentlobo ezimbini ze-ongus, i-xg-pon kunye ne-xgs-pon.

2.2 Ukudibana kwe-xgs-pon kunyeGpn

Ukusukela ukuba i-pullink / i-Doellink yahlukile kuleyo ye-GEN, i-xgs-pon isebenzisa isisombululo se-combo sokwabelana nge-odn nge-GEN. Ngomgaqo wesisombululo se-combo, sibhekisa kwinqaku elithi "Ingxoxo ngesisombululo sokuphucula ukusetyenziswa kwezixhobo ze-XG-Pon yeBhodi yombhali we-combo".
Imodyuli ye-combo ye-comboocal ye-XMS-PON idibanisa imodyuli ye-phephecal yemodyuli, i-xms-pon-pon yemodyuli kunye ne-WDM Paunter.
Kwindlela ephezulu yokuphakama, emva kokuba i-Sgn-Poilical ingena kwi-XMS-POBO POR, WDM I-GORY SINGN kunye ne-XMS-PNS-PONI SINGN ngokweendlela ezahlukeneyo.
Kwindlela ephantsi, imiqondiso evela kwisitayile se-GONO kunye neChs-Pon Channels ye-WDM, kwaye umqondiso oxubeneyo ukhutshiwe kwi-ODN. Kuba amaza ahlukile, iintlobo ezahlukeneyo ze-otus ikhetha i-wavelength efunekayo yokufumana imiqondiso kwiifilitha zangaphakathi.
Kuba i-xgs-pon ngokwemvelo ixhasa i-bieg-pon, isisombululo se-combo sexgs-Pon ixhasa ukufikelela kwi-GEN, i-xg-pon kunye ne-xgs-pon yeentlobo ezintathu ze-onus. Imodyuli ye-combo ye-combo ye-XGS-Pon ikwabizwa ngokuba yimodyuli emithathu yemodyuli yemodyuli ebizwa ngokuba yimodyuli ye-comb ye-comboical kuba ixhasa iindidi ezixubeneyo ze-onus).

3. Imo yentengiso
Ichaphazeleka ziindleko zokufaka kunye nokuvuthwa kwezixhobo, ixabiso langoku izixhobo ze-xgs-pon liphezulu kakhulu kune-xg-pon. Phakathi kwazo, ixabiso leyunithi le-OLT (kubandakanya iBhodi yomsebenzisi we-combo) imalunga ne-20% ephezulu, kwaye ixabiso leyunithi le-OU lingaphezulu kwe-50% ephezulu.
Nangona imigca enikezelweyo engenamsebenzi kufuneka ibonelele ngesekethe / i-DownLink Sertheds, ezona zithuthi zinemigca enikezelweyo ye-Inbound isalawulwa yindlela yokuziphatha elandelayo. Nangona kukho iimeko ezingaphezulu nangakumbi apho abasebenzisi bahlawula ngakumbi kwi-windows endwidth, phantse akukho tyala leenkonzo ezingenakufikeleleka nge-XG-POL ngaphandle kufuneka zifikelele kwi-xgs-pon.
