PON (Passive Optical Network) yog hais txog kev siv kho qhov muag network uas ODN (Optical Distribution Network) nruab nrab ntawm OLT (Optical Line Terminal) thiab ONU (Optical Network Unit) txhua tus siv cov khoom siv passive.
PON yog point-to-multipoint (P2MP) optical access system, uas tuaj yeem txuag cov peev txheej fiber ntau, ODN tsis xav tau lub zog hluav taws xob, cov neeg siv nkag tau yooj yim, thiab txhawb kev siv ntau yam. Nws yog ib tug broadband fiber ntau siv tshuab uas cov neeg ua hauj lwm tam sim no nquag txhawb nqa, Muaj ob lub thev naus laus zis, EPON thiab GPON.
PON system siv WDM (Dense Wavelength Division Multiplexing) thev naus laus zis kom ua tiav ib leeg-fiber bidirectional kis tau tus mob.
Txhawm rau cais cov khoom nkag thiab tawm ntawm ntau tus neeg siv ntawm tib lub fiber ntau, ob txoj kev siv thev naus laus zis hauv qab no tau siv:
● Cov ntaub ntawv qis qis siv cov cuab yeej tshaj tawm;
●Upstream cov ntaub ntawv ntws tau txais TDMA thev naus laus zis.
●Txhua qhov chaw nres nkoj PON tuaj yeem ua tiav qhov siab tshaj plaws kev sib kis ceev ntawm 1.25G sab sauv thiab 2.5G nqes ntws
