XG-PON uye XGS-PON ese ari maviri ndeeGPON akatevedzana, uye kubva muhunyanzvi nzira, XGS-PON ndiyo shanduko yetekinoroji yeXG-PON.
XG-PON uye XGS-PON zvose zviri 10G PON, misiyano mikuru ndeiyi: XG-PON is asymmetric PON, uye chiyero chepamusoro / pasi chePON port 2.5G/10G;XGS-PON inofananidzwa PON, uye chiyero chepamusoro / chepasi chePON chiteshi ndeye 10G/10G.

Iwo makuru ePON matekinoroji ari kushandiswa parizvino iGPON neXG-PON, ese GPON neXG-PON ane asymmetric PON.Sezvo iyo yekumusoro/pasi data yevashandisi ichiwanzo asymmetric, kutora rimwe tier guta semuenzaniso, iyo uplink traffic yeOLT ingori 22% yeiyo downlink paavhareji, saka hunyanzvi hunhu hweasymmetric PON hunoenderana nezvinodiwa nevashandisi.Zvinotonyanya kukosha, iyo uplink rate yeasymmetric PON yakaderera, mutengo wekutumira zvinhu senge lasers muONU wakaderera, uye mutengo wemidziyo wakaderera.
Kugarisana kweXGS-PON ine XG-PON uye GPON,XGS-PON inyanzvi yekushanduka kweGPON neXG-PON, inotsigira kuwana kwakasanganiswa kweGPON, XG-PON uye XGS-PON.
XGSPON tekinoroji
Iyo downlink yeXGS-PON inotora nzira yekutepfenyura, uye iyo uplink inotora nzira yeTDMA.
Sezvo iyo downlink wavelength uye downlink rate yeXGS-PON uye XG-PON yakafanana, iyo downlink yeXGS-PON haisiyanise pakati peXGS-PON ONU neXG-PON ONU, iyo inopatsanura yekuona inotepfenyura chiratidzo chepasi chepasi kune imwe neimwe XG. (S) -PON (XG-PON uye XGS-PON) ONU mune imwecheteyo ODN link, uye ONU imwe neimwe inosarudza kugamuchira chiratidzo chayo uye kurasa zvimwe zviratidzo.
Iyo kumusoro kweiyo XGS-PON inotumira data zvinoenderana nenguva yakatarwa, uye ONU inotumira data mukati meOLT-inopihwa rezinesi nguva.OLT yakavakirwa pazvinodiwa zvetraffic zveONU dzakasiyana uye rudzi rweONU.Dynamically govera nguva slots.Nhamba yekufambisa data ndeye 2.5Gbps munguva yakagoverwa kuXG-PON ONU, uye 10Gbps munguva yakagoverwa ku XGS-PON ONU.
Sezvo kureba kwekumusoro/pasi kwakasiyana neGPON, XGS-PON inoshandisa chirongwa cheCombo kugovera ODN neGPON.
XGS-PON's Combo optical module inobatanidza GPON optical module, XGS-PON optical module uye WDM musanganisi.
Muchikamu chepamusoro, mushure mokunge chiratidzo chemaziso chinopinda muchiteshi che XGS-PON Combo, WDM inosvina chiratidzo cheGPON uye XGS-PON chiratidzo maererano newavelength, uye zvino inotumira chiratidzo kune zvakasiyana-siyana.
Munzira yedownlink, chiratidzo chinobva kuGPON & XGS-PON chiteshi chinowedzerwa kuburikidza neWDM, uye chiratidzo chakavhenganiswa chiri downlink kuONU kuburikidza neODN, uye nokuti marefu akasiyana-siyana, marudzi akasiyana-siyana eONU anosarudza marefu avanoda kuburikidza nemukati. mafirita kugamuchira zviratidzo.
Sezvo XGS-PON inotsigira kugarisana neXG-PON, mhinduro yeCombo yeXGS-PON inotsigira kuwanikwa kwakasanganiswa kweGPON, XG-PON uye XGS-PON, uye Combo optical module yeXGS-PON inonziwo matatu-modhi. Combo optical module (apo iyo Combo optical module yeXG-PON inodaidzwa kuti maviri-mode Combo optical module nekuti inotsigira kusanganiswa kweGPON neXG-PON).
