Ubuchwepheshe be-PON obuphambili obusetyenziswayo ngoku yi-GPON kunye ne-XG-PON, zombini i-GPON kunye ne-XG-PON zi-asymmetric PON.Ekubeni idatha ephezulu / ezantsi yabasebenzisi ngokuqhelekileyo i-asymmetric, ithatha idolophu ethile ye-tier njengomzekelo, i-traffic ye-uplink ye-OLT yi-22% kuphela ye-downlink ephakathi, ngoko ke iimpawu zobugcisa ze-PON ye-asymmetric ngokusisiseko ihambelana neemfuno zabasebenzisi.Okubaluleke ngakumbi, izinga le-uplink ye-PON ye-asymmetric iphantsi, iindleko zokuhambisa izinto ezifana ne-lasers kwi-ONU ziphantsi, kwaye iindleko zezixhobo ziphantsi ngokuhambelanayo.
Ukuhlalisana kwe-XGS-PON kunye ne-XG-PON kunye ne-GPON, i-XGS-PON yi-evolution yobugcisa be-GPON kunye ne-XG-PON, exhasa ukufikelela okuxubileyo kwe-GPON, i-XG-PON kunye ne-XGS-PON.
Itekhnoloji yeXGSPON
I-downlink ye-XGS-PON ithatha indlela yokusasaza, kwaye i-uplink ithatha indlela ye-TDMA.
Ukusukela ukuba i-downlink wavelength kunye ne-downlink rate ye-XGS-PON kunye ne-XG-PON ziyafana, i-downlink ye-XGS-PON ayihlukanisi phakathi kwe-XGS-PON ONU kunye ne-XG-PON ONU, i-optical splitter isasaza isibonakaliso esezantsi kwi-XG nganye. (S) -PON (XG-PON kunye ne-XGS-PON) I-ONU kwikhonkco elifanayo le-ODN, kwaye i-ONU nganye ikhetha ukufumana isignali yayo kwaye ilahle ezinye iimpawu.
Ukunyuka kwe-XGS-PON idlulisela idatha ngokwexesha lokubeka ixesha, kwaye i-ONU ithumela idatha ngaphakathi kwexesha le-OLT-layisenisi yexesha.I-OLT isekelwe kwiimfuno zendlela yee-ONU ezahlukeneyo kunye nodidi lwe-ONU.Yabela ixesha kwiindawo zokubeka ngamandla.Izinga lokudluliselwa kwedatha yi-2.5Gbps kwixesha elinikezelwe kwi-XG-PON ONU, kunye ne-10Gbps kwixesha elinikezelwe kwi-XGS-PON ONU.
Ukusukela ukuba phezulu/ezantsi ubude bamaza ahlukile kwi-GPON, i-XGS-PON isebenzisa i-Combo scheme ukwabelana nge-ODN ne-GPON.
Imodyuli ye-XGS-PON ye-Combo optical idibanisa i-GPON imodyuli ye-optical, i-XGS-PON imodyuli ye-optical kunye ne-WDM yokudibanisa.
Kwi-uplink direction, emva kokuba i-optical signal ingena kwi-port ye-XGS-PON Combo, i-WDM ihlunga isignali ye-GPON kunye ne-XGS-PON yesiginali ngokwe-wavelength, kwaye emva koko ithumela isignali kumajelo ahlukeneyo.
Kwisalathiso se-downlink, isignali evela kwi-GPON & XGS-PON channel i-multiplexed nge-WDM, kwaye isignali edibeneyo i-downlink kwi-ONU ngokusebenzisa i-ODN, kwaye ngenxa yokuba i-wavelengths iyahluka, iindidi ezahlukeneyo ze-ONU zikhetha ubude bazo obufunwayo ngokusebenzisa ngaphakathi. izihluzi ukufumana imiqondiso.
Ekubeni i-XGS-PON ixhasa ngokwendalo ukuhlalisana kunye ne-XG-PON, isisombululo se-Combo se-XGS-PON sixhasa ukufikelela okuxubileyo kweGPON, XG-PON kunye ne-XGS-PON, kunye ne-Combo optical module ye-XGS-PON ikwabizwa ngokuba yimodyuli emithathu. Combo imodyuli yokukhanya yeCombo (ngelixa iCombo Optical module ye XG-PON ibizwa ngokuba yimodyuli ye-Combo Optical mode kuba ixhasa ufikelelo oluxutyiweyo lwe GPON kunye ne XG-PON).
