I-XG-PON ne-XGS-PON zombili zingezochungechunge lwe-GPON, futhi kusukela kumephu yomgwaqo yezobuchwepheshe, i-XGS-PON iwukuziphendukela kwemvelo kwe-XG-PON.
I-XG-PON ne-XGS-PON zombili ziyi-10G PON, umehluko omkhulu uthi: I-XG-PON i-asymmetric PON, futhi izinga eliphezulu/phansi lembobo ye-PON ngu-2.5G/10G;I-XGS-PON i-PON yokulinganisa, futhi izinga eliphezulu/ezansi lomfula wembobo ye-PON ngu-10G/10G.

Ubuchwepheshe be-PON obuyinhloko obusetshenziswayo njengamanje i-GPON ne-XG-PON, kokubili i-GPON ne-XG-PON buyi-PON e-asymmetric.Njengoba idatha ephezulu/phansi yabasebenzisi ngokuvamile i-asymmetric, ukuthatha idolobha lesigaba esithile njengesibonelo, ithrafikhi ekhuphukayo ye-OLT ingu-22% kuphela we-downlink ngokwesilinganiso, ngakho izici zobuchwepheshe ze-PON e-asymmetric zifana ngokuyisisekelo nezidingo zabasebenzisi.Okubaluleke nakakhulu, izinga lokukhuphuka kwe-asymmetric PON liphansi, izindleko zokudlulisa izingxenye ezifana nama-lasers ku-ONU ziphansi, futhi izindleko zemishini ziphansi ngokulinganayo.
Ukuhlalisana kwe-XGS-PON ne-XG-PON ne-GPON, i-XGS-PON iwukuziphendukela kwemvelo kwezobuchwepheshe kwe-GPON ne-XG-PON, esekela ukufinyelela okuxubile kwe-GPON, i-XG-PON ne-XGS-PON.
Ubuchwepheshe be-XGSPON
I-downlink ye-XGS-PON isebenzisa indlela yokusakaza, futhi i-uplink isebenzisa indlela ye-TDMA.
Njengoba i-downlink wavelength ne-downlink rate ye-XGS-PON ne-XG-PON iyafana, i-downlink ye-XGS-PON ayihlukanisi phakathi kwe-XGS-PON ONU ne-XG-PON ONU, isihlukanisi esibonakalayo sisakaza isignali yokubona eya phansi ku-XG ngayinye. (S)-PON (XG-PON kanye ne-XGS-PON) ONU kusixhumanisi esifanayo se-ODN, futhi i-ONU ngayinye ikhetha ukwamukela isignali yayo futhi ilahle ezinye izimpawu.
Ukukhuphuka komfula kwe-XGS-PON kudlulisa idatha ngokuya ngesikhathi, futhi i-ONU ithumela idatha ngaphakathi kwendawo enelayisensi ye-OLT.I-OLT isuselwe kuzidingo zethrafikhi zama-ONU ahlukene kanye nohlobo lwe-ONU.Yabelana ngokunamandla izikhala zesikhathi.Izinga lokudluliswa kwedatha ngu-2.5Gbps esikhaleni sesikhathi esabelwe i-XG-PON ONU, kanye no-10Gbps esikhaleni sesikhathi esabelwe i-XGS-PON ONU.
Njengoba ubude begagasi obuphezulu/phansi buhlukile ku-GPON, i-XGS-PON isebenzisa uhlelo lwe-Combo ukwabelana nge-ODN ne-GPON.
I-XGS-PON's Combo optical module ihlanganisa i-GPON optical module, i-XGS-PON optical module nesihlanganisi se-WDM.
Esiqondisweni se-uplink, ngemva kokuba isignali ye-optical ingena echwebeni le-XGS-PON Combo, i-WDM ihlunga isignali ye-GPON kanye nesignali ye-XGS-PON ngokusho kwe-wavelength, bese ithumela isignali eziteshini ezahlukene.
Esiqondisweni se-downlink, isignali evela esiteshini se-GPON & XGS-PON iphindwaphindwa nge-WDM, futhi isignali exubile ixhunywe phansi ku-ONU ngokusebenzisa i-ODN, futhi ngenxa yokuthi ubude begagasi buhlukile, izinhlobo ezahlukene zamaza ama-ONU zikhetha ubude obufunayo ngokusebenzisa ngaphakathi. izihlungi ukuthola amasignali.
Njengoba i-XGS-PON isekela ngokwemvelo ukuphilisana ne-XG-PON, isixazululo se-Combo se-XGS-PON sisekela ukufinyelela okuxubile kwe-GPON, i-XG-PON ne-XGS-PON, futhi i-Combo optical module ye-XGS-PON ibizwa nangokuthi imodi emithathu. Imojuli ye-Combo optical (ngenkathi i-Combo optical module ye-XG-PON ibizwa ngokuthi imojuli ye-Combo optical yemodi ezimbili ngoba isekela ukufinyelela okuxubile kwe-GPON ne-XG-PON).
Ukukugcina uphambi kwabanye, siphakamisa ukuthi usebenzise i-XGXPON OLT LM808XGS yethu, imininingwane eyengeziwe sicela upheqa iwebhu yethu:www.limeetech.com
