GPON (Gigabit-Capable Passive Optical Network) thev naus laus zis yog kev ua haujlwm siab, ua haujlwm tau zoo, thiab muaj peev xwm loj hauv kev siv thev naus laus zis uas tau siv dav hauv fiber-to-the-home (FTTH) optical access networks.Hauv GPON network,OLT (Optical Line Terminal)thiab ONT (Optical Network Terminal) yog ob qho tseem ceeb.Lawv txhua tus muaj lub luag haujlwm sib txawv thiab ua haujlwm ua ke kom ua tiav cov ntaub ntawv ceev thiab muaj txiaj ntsig zoo.
Qhov txawv ntawm OLT thiab ONT nyob rau hauv cov nqe lus ntawm lub cev qhov chaw thiab lub luag hauj lwm positioning: OLT feem ntau yog nyob rau hauv nruab nrab ntawm lub network, uas yog, lub hauv paus chaw ua hauj lwm, ua si lub luag hauj lwm ntawm "commander".Nws txuas ntau ONTs thiab yog lub luag haujlwm rau kev sib txuas lus nrog covONTsntawm tus neeg siv sab, thaum sib koom tes thiab tswj cov ntaub ntawv xa mus.Nws tuaj yeem hais tias OLT yog lub hauv paus thiab tus ntsuj plig ntawm tag nrho GPON network.ONT nyob ntawm tus neeg siv kawg, uas yog, ntawm ntug ntawm lub network, ua si lub luag haujlwm ntawm "tub rog".Nws yog ib qho cuab yeej ntawm cov neeg siv kawg thiab siv los txuas cov khoom siv davhlau ya nyob twg, xws li khoos phis tawj, TVs, routers, thiab lwm yam, txhawm rau txuas cov neeg siv mus rau lub network.
Kev ua haujlwm sib txawv:OLT thiab ONT muaj qhov sib txawv.Lub luag haujlwm tseem ceeb ntawm OLT suav nrog kev sib sau cov ntaub ntawv, kev tswj hwm thiab kev tswj hwm, nrog rau kev sib kis thiab txais cov teeb liab kho qhov muag.Nws yog lub luag haujlwm rau kev sib sau cov ntaub ntawv ntws los ntawm ntau tus neeg siv los xyuas kom meej cov ntaub ntawv xa mus tau zoo.Tib lub sijhawm, OLT tseem cuam tshuam nrog lwm OLTs thiab ONTs los ntawm kev sib txuas lus raws tu qauv los tswj thiab tswj tag nrho lub network.Tsis tas li ntawd, OLT kuj hloov cov teeb liab hluav taws xob rau hauv cov teeb liab kho qhov muag thiab xa lawv mus rau hauv cov khoom siv kho qhov muag.Nyob rau tib lub sijhawm, nws muaj peev xwm tau txais cov teeb liab kho qhov muag los ntawm ONT thiab hloov mus rau hauv cov teeb liab hluav taws xob rau kev ua haujlwm.Lub luag haujlwm tseem ceeb ntawm ONT yog los hloov cov teeb liab kho qhov muag kis tau los ntawm cov khoom siv kho qhov muag rau hauv cov teeb liab hluav taws xob thiab xa cov hluav taws xob teeb liab mus rau ntau yam khoom siv.Tsis tas li ntawd, ONT tuaj yeem xa, sib sau, thiab ua ntau hom ntaub ntawv los ntawm cov neeg siv khoom thiab xa mus rau OLT.
Qhov sib txawv ntawm qib technical:OLT thiab ONT kuj muaj qhov sib txawv hauv kev tsim kho vajtse thiab software programming.OLT yuav tsum muaj cov txheej txheem ua tau zoo, muaj peev xwm loj, thiab kev sib txuas ceev ceev los tiv thaiv cov ntaub ntawv loj thiab cov kev xav tau sib kis.ONT yuav tsum tau hloov kho kho vajtse thiab software tsim kom haum rau cov kev xav tau sib txawv ntawm cov neeg siv sib txawv thiab qhov sib txawv ntawm cov khoom siv sib txawv.

OLT thiab ONT txhua tus xav tias muaj lub luag haujlwm sib txawv thiab ua haujlwm hauv GPON network.OLT nyob rau ntawm lub network chaw thiab yog lub luag haujlwm rau cov ntaub ntawv sib sau, kev tswj hwm thiab kev tswj hwm, nrog rau kev sib kis thiab txais cov teeb liab kho qhov muag;thaum ONT nyob rau ntawm tus neeg siv kawg thiab yog lub luag haujlwm rau hloov cov teeb liab kho qhov muag rau hauv cov teeb liab hluav taws xob thiab xa mus rau cov neeg siv khoom siv.Ob leeg ua hauj lwm ua ke los ua kom lub GPON network muab kev pabcuam kev xa xov ceev thiab cov ntaub ntawv muaj txiaj ntsig kom tau raws li cov neeg siv khoom xav tau rau kev siv dav dav.
