XG-PON thiab XGS-PON ob leeg muaj nyob rau hauv GPON series, thiab los ntawm cov txheej txheem kev qhia, XGS-PON yog cov thev naus laus zis hloov pauv ntawm XG-PON.
XG-PON thiab XGS-PON yog ob qho tib si 10G PON, qhov sib txawv tseem ceeb yog: XG-PON yog asymmetric PON, thiab nce / nqis ntawm PON chaw nres nkoj yog 2.5G / 10G;XGS-PON yog symmetrical PON, thiab tus nqi nce / nqis ntawm PON chaw nres nkoj yog 10G / 10G.

Lub ntsiab PON yees siv tam sim no yog GPON thiab XG-PON, ob qho tib si GPON thiab XG-PON yog asymmetric PON.Txij li thaum cov ntaub ntawv nce / nqis ntawm cov neeg siv feem ntau yog asymmetric, noj ib lub nroog ib ntus ua piv txwv, lub tsheb thauj mus los ntawm OLT tsuas yog 22% ntawm qhov downlink nyob rau nruab nrab, yog li cov yam ntxwv ntawm asymmetric PON yeej phim cov kev xav tau ntawm cov neeg siv.Qhov tseem ceeb tshaj, tus nqi nce ntawm asymmetric PON yog qis, tus nqi ntawm cov khoom sib kis xws li lasers hauv ONU yog qis dua, thiab cov khoom siv tus nqi qis dua.
Kev sib koom ua ke ntawm XGS-PON nrog XG-PON thiab GPON, XGS-PON yog kev hloov pauv ntawm GPON thiab XG-PON, uas txhawb kev sib xyaw ntawm GPON, XG-PON thiab XGS-PON.
XGSPON technology
Lub downlink ntawm XGS-PON txais yuav txoj kev tshaj tawm, thiab lub uplink txais txoj kev TDMA.
Txij li thaum lub downlink wavelength thiab downlink tus nqi ntawm XGS-PON thiab XG-PON yog tib yam, lub downlink ntawm XGS-PON tsis txawv ntawm XGS-PON ONU thiab XG-PON ONU, lub optical splitter broadcasts downstream optical teeb liab rau txhua XG. (S)-PON (XG-PON thiab XGS-PON) ONU hauv tib qhov txuas ODN, thiab txhua ONU xaiv tau txais nws tus kheej lub teeb liab thiab muab pov tseg lwm cov cim.
Cov dej ntws ntawm XGS-PON xa cov ntaub ntawv raws li lub sijhawm, thiab ONU xa cov ntaub ntawv tsis pub dhau lub sijhawm OLT- ntawv tso cai.OLT yog raws li cov kev xav tau ntawm cov tsheb sib txawv ntawm ONUs thiab hom ONU.Dynamically faib cov sij hawm slots.Cov ntaub ntawv kis tus nqi yog 2.5Gbps nyob rau hauv lub sij hawm qhov chaw faib rau lub XG-PON ONU, thiab 10Gbps nyob rau hauv lub sij hawm qhov chaw faib rau lub XGS-PON ONU.
Txij li thaum lub nce / nqis wavelength txawv ntawm GPON, XGS-PON siv lub tswv yim Combo los qhia ODN nrog GPON.
XGS-PON's Combo optical module integrates GPON optical module, XGS-PON optical module thiab WDM combiner.
Hauv kev taw qhia uplink, tom qab lub teeb liab kho qhov muag nkag mus rau XGS-PON Combo chaw nres nkoj, WDM lim cov teeb liab GPON thiab XGS-PON teeb liab raws li lub wavelength, thiab tom qab ntawd xa cov teeb liab mus rau ntau qhov sib txawv.
Hauv kev taw qhia downlink, lub teeb liab los ntawm GPON & XGS-PON channel yog multiplexed los ntawm WDM, thiab cov teeb liab sib xyaw yog downlink rau ONU los ntawm ODN, thiab vim hais tias cov wavelengths txawv, ntau hom ONUs xaiv lawv qhov xav tau wavelengths los ntawm sab hauv. lim kom tau txais cov cim.
Txij li thaum XGS-PON ib txwm txhawb kev sib koom ua ke nrog XG-PON, Combo daws ntawm XGS-PON txhawb kev sib xyaw ntawm GPON, XG-PON thiab XGS-PON, thiab Combo optical module ntawm XGS-PON tseem hu ua peb hom. Combo optical module (thaum lub Combo optical module ntawm XG-PON yog hu ua ob hom Combo optical module vim nws txhawb kev sib xyaw ntawm GPON thiab XG-PON).
