1. AP, wireless router,transmits network signals los ntawm twisted khub.Los ntawm AP qhov muab tso ua ke, nws hloov cov teeb liab hluav taws xob rau hauv xov tooj cua thiab xa tawm.
2. ONU (Optical Network Unit)optical network unit.PON cov khoom siv network, PON siv ib qho fiber ntau optical txuas rau OLT, thiab tom qab ntawd OLT txuas nrog ONU.ONU muab cov ntaub ntawv, IPTV (Interactive Internet TV), suab thiab lwm yam kev pabcuam.PON chaw nres nkoj ntawm no yog hais txog qhov chaw nres nkoj ntawm OLT.Ib qho PON chaw nres nkoj sib raug rau ib qho optical splitter.PON (Passive Optical Network) passive optical network.PON chaw nres nkoj feem ntau yog hais txog qhov chaw nres nkoj downstream ntawm OLT thiab txuas nrog lub optical splitter.Qhov chaw nres nkoj sab saud ntawm ONU tuaj yeem hu ua PON chaw nres nkoj.Optical modem hais txog fiber ntau optic modem, thiab tag nrho cov khoom siv fiber ntau optic siv-kawg hloov dua siab tshiab tuaj yeem raug hu ua optical modem.Modulation yog hloov cov teeb liab digital rau hauv cov teeb liab analog xa mus rau hauv xov tooj, thiab demodulation yog hloov cov teeb liab analog rau hauv cov teeb liab digital, sib sau ua ke hu ua modem.Peb siv cov xov tooj los xa cov teeb liab analog, thaum PCs xa cov teeb liab digital.Yog li ntawd, thaum txuas rau Is Taws Nem los ntawm kab xov tooj, koj yuav tsum siv lub modem.
3. ONT (Optical Nerwork Unit)Optical network khoom, sib npaug rau ONU.Nws yog ib qho khoom siv kho qhov muag siv rau ntawm tus neeg siv kawg.Qhov txawv yog: ONT yog lub davhlau ya nyob twg kho qhov muag, nyob ncaj qha ntawm tus neeg siv kawg, thaum ONU yog chav kho qhov muag, thiab tej zaum yuav muaj lwm cov tes hauj lwm ntawm nws thiab cov neeg siv, xws li Ethernet.CeitaTech's ONU / ONT cov khoom tuaj yeem siv ua ONU / ONT cov khoom lossis ua routers.Ib yam khoom muaj ntau yam siv.
4. OLT (optical kab davhlau ya nyob twg)optical kab davhlau ya nyob twg, cov khoom siv davhlau ya nyob twg siv los txuas cov kab hluav taws xob kho qhov muag.Kev Ua Haujlwm: (1) Xa cov ntaub ntawv Ethernet mus rau ONU (Optical Network Unit) hauv kev tshaj tawm, (2) Pib thiab tswj cov txheej txheem sib txawv thiab sau cov ntaub ntawv sib txawv, (3) faib cov bandwidth rau ONU, uas yog, tswj lub pib ntawm ONU xa cov ntaub ntawv.pib lub sij hawm thiab xa qhov rais loj.Lub network txuas nrog nruab nrab ntawm cov khoom siv hauv chaw ua haujlwm (OLT) thiab cov neeg siv khoom siv (ONU / ONT) los ntawm kev faib khoom siv kho qhov muag (ODN) uas muaj cov kab hluav taws xob tsis zoo thiab cov khoom siv kho qhov muag / cov sib txuas.
5. Kho qhov muagfiber ntau transceiveryog Ethernet kis xov xwm hloov dua siab tshiab chav tsev uas sib pauv luv luv-ntu twisted khub hluav taws xob teeb liab thiab cov teeb liab qhov muag ntev.Nws tseem hu ua photoelectric converter (Fiber Converter) nyob rau hauv ntau qhov chaw..Cov khoom siv feem ntau yog siv nyob rau hauv qhov chaw network tiag tiag uas Ethernet cables tsis tuaj yeem npog thiab kho qhov muag fiber ntau yuav tsum tau siv los txuas ntxiv kev sib kis, thiab feem ntau yog nyob rau hauv daim ntawv thov txheej txheej ntawm broadband cheeb tsam hauv cheeb tsam network;pab txuas lub mais kawg ntawm cov kab fiber ntau optic mus rau lub nroog hauv cheeb tsam network thiab Nyob rau sab nraud.
