Wireless router ； ONU ； ONT ； OLT ； fibre optique transceiver terminology ibisobanuro

1. AP, router idafite umugozi,Kohereza ibimenyetso byurusobe binyuze muburyo bubiri.Binyuze mu cyegeranyo cya AP, ihindura ibimenyetso byamashanyarazi mubimenyetso bya radio ikabyohereza hanze.

2. ONU (Igice cya Optical Network Unit)umurongo wa optique.PON ibikoresho byurusobe, PON ikoresha fibre optique imwe kugirango ihuze na OLT, hanyuma OLT ihuze na ONU.ONU itanga amakuru, IPTV (Televiziyo ya interineti ikora), ijwi nizindi serivisi.Icyambu cya PON hano kivuga icyambu kuri OLT.Icyambu kimwe cya PON gihuye na optique imwe.PON (Umuyoboro wa Passive Optical Network) umuyoboro mwiza wa optique.Icyambu cya PON muri rusange cyerekeza ku cyambu cyo hasi cya OLT kandi gihujwe na optique itandukanya.Icyambu cyo hejuru cya ONU gishobora nanone kwitwa icyambu cya PON.Modem optique yerekeza kuri fibre optique, kandi ibikoresho byose bya fibre optique ukoresha-amaherezo yo guhindura ibikoresho bishobora kwerekanwa hamwe nka modem optique.Guhindura ni uguhindura ibimenyetso bya digitale mubimenyetso bisa byoherejwe kumurongo wa terefone, kandi demodulation ni uguhindura ibimenyetso bisa mubimenyetso bya digitale, hamwe byitwa modem.Dukoresha imirongo ya terefone kugirango twohereze ibimenyetso bisa, mugihe PC yohereza ibimenyetso bya digitale.Kubwibyo, mugihe uhuza interineti ukoresheje umurongo wa terefone, ugomba gukoresha modem.

3. ONT (Optical Nerwork Unit)ibikoresho bya neti optique, bihwanye na ONU.Nibikoresho bya neti optique ikoreshwa kumukoresha wa nyuma.Itandukaniro ni: ONT numuyoboro wa optique, uherereye kumurongo wumukoresha, mugihe ONU numuyoboro wa optique, kandi hashobora kubaho indi miyoboro hagati yayo nuyikoresha, nka Ethernet.Ibicuruzwa bya CeitaTech ONU / ONT birashobora gukoreshwa nkibicuruzwa bya ONU / ONT cyangwa nka router.Igicuruzwa kimwe gifite imikoreshereze myinshi.

4. OLT (umurongo wa optique)umurongo wa optique, ibikoresho bya terefone bikoreshwa muguhuza optique fibre trunk imirongo.Imikorere: (1) Kohereza amakuru ya Ethernet kuri ONU (Optical Network Unit) muburyo bwo gutangaza, (2) Gutangiza no kugenzura inzira zingana no kwandika amakuru atandukanye, (3) Tanga umurongo mugari kuri ONU, ni ukuvuga kugenzura i gutangira ONU yohereza amakuru.gutangira igihe no kohereza ingano yidirishya.Umuyoboro uhuza ibikoresho byo mu biro bikuru (OLT) nibikoresho byabakoresha (ONU / ONT) binyuze mumurongo wo gukwirakwiza optique (ODN) ugizwe ninsinga za optique optique hamwe na optique itandukanya / ikomatanya.

5. Ibyizafibre transibiverni Ethernet yohereza itangazamakuru ryihinduranya rihana intera ngufi ihindagurika ibyuma byamashanyarazi nibimenyetso birebire bya optique.Yitwa kandi guhinduranya amashanyarazi (Guhindura fibre) ahantu henshi..Igicuruzwa gikunze gukoreshwa muburyo busanzwe bwurusobe aho insinga za Ethernet zidashobora gupfuka kandi fibre optique igomba gukoreshwa kugirango yongere intera yoherejwe, kandi mubisanzwe ishyirwa mubikorwa byogukoresha umurongo mugari wa metero nini ya metero nini;gufasha guhuza ibirometero byanyuma bya fibre optique kumurongo wa metero nkuru hamwe no kumurongo wo hanze.
