Tej zaum koj yuav tsis paub tias "PON" yog dab tsi (feem ntau nyeem ua "pang"), tab sis koj yuav tsum tau hnov txog "fiber rau tsev".
Tej zaum koj yuav tsis paub tias "ONU" yog dab tsi (feem ntau nyeem "ONU"), tab sis thaum koj qhib lub thawv hluav taws xob tsis muaj zog hauv koj lub tsev, koj yuav tsum pom "lub thawv me" uas muaj fiber ntau optical.Lub thawv me me no yog ONU (Optical Network Unit, optical network unit), feem ntau hu ua "ONU".Niaj hnub no tus protagonist —— "PON" (Passive Optical Network, passive optical network), yog tus yuam sij kom ua tiav qhov kev siv fiber ntau, yog "kawg mais" optical fiber kis tau tus mob ntawm lub network thiab cov neeg siv.
Wlub kaus mom yog PON?
Txhua tsev neeg kho qhov muag fiber ntau, txuas tom qab lub network loj, cia peb ua raws li cov khoom siv fiber ntau, taug qab cov kwj deg, tshawb xyuas ua ke.Cov fiber ntau kho qhov muag txuas nrog ONU los ntawm cov splitter hauv qhov tsis muaj zog hluav taws xob zoo / txoj hauv kev, uas tuaj yeem faib cov teeb liab kho qhov muag rau ntau txoj hauv kev hauv ib qho kev faib ua feem.Cov teeb liab kho qhov muag nkag mus rau qhov muag pom qhov sib cais los ntawm cov kab hluav taws xob kho qhov muag OLT (Optical Line Terminal).OLT, ONU, thiab nruab nrab ntawm ob "kev sib kis" ODN (Optical Distribution Network, optical tis network) ua lub PON network.Ntawm:
OLT yog tus neeg teb xov tooj-sab ntaus ntawv lub luag haujlwm rau kev xa cov ntaub ntawv rau cov lag luam qib siab.
ONU yog ib qho khoom siv sab hauv lub luag haujlwm rau kev txais cov ntaub ntawv xa los ntawm OLT thiab ncaj qha rau cov neeg siv.
Peb tuaj yeem tau txais kev nkag siab luv luv ntawm PON network architecture raws li daim duab hauv qab no.
Shenzhen HDV Photoelectron Technology Ltd. yog tus kws tshaj lij ONU cov cuab yeej tsim khoom tseem yog kev sib txuas lus ntse ONU thiab cov chaw tsim khoom lag luam, peb lub tuam txhab tam sim no muag ntau yam khoom siv sib txuas lus sab saud, xws li: Fiber media converter, Ethernet hloov, OLT khoom, ONU khoom thiab yog li ntawd.Yog tias koj xav paub ntau ntxiv txog kev sib txuas lus technology, txais tos hu rau peb txhua lub sijhawm.
