Ni ubuhe buryo bw'urusobe rwa Optical Access Network (OAN)
Umuyoboro wa optique (OAN) bivuga gukoresha fibre optique nkibikoresho nyamukuru byohereza kugirango umenye amakuru yohereza amakuru kumurongo. Ihujwe na serivisi node binyuze mumurongo wa optique (OLT), kandi uhujwe nu mukoresha binyuze mumurongo wa optique (ONU). Umuyoboro wa fibre optique urimo ibikoresho bya kure-optique y'urusobekerane hamwe nibikoresho byo mu biro bikuru-optique y'umurongo wa terefone, bihujwe n'ibikoresho byohereza.Ibice by'ingenzi bigize sisitemu niOLTna kureONU.Barangije guhindura protocole yerekana ibimenyetso kuva serivise ya serivise (SNI) kugeza kumurongo wumukoresha (UNI) mumurongo wose winjira. Igikoresho cyo kwinjira ubwacyo nacyo gifite ubushobozi bwo guhuza kandi gishobora gukora uburyo butandukanye bwa topologiya. Muri icyo gihe, ibikoresho byinjira nabyo bifite imirimo yo kubungabunga no kugenzura kure, kugenzura imiyoboro yo kubungabunga binyuze mu buryo bworoshye bwo kohereza, no kuyizana mu kigo gishinzwe imiyoborere kugira ngo imiyoborere ihuriweho binyuze mu masezerano ajyanye no gucunga imiyoboro.
Uruhare rwaOLTni ugutanga intera hagati yumurongo winjira hamwe nahohindura, kandi ushyikirane numuyoboro wa optique kuruhande rwabakoresha binyuze mumashanyarazi. Itandukanya rwose imikorere yo guhinduranya yahinduraKuva Umukoresha. Umurongo wa optique utanga kubungabunga no kugenzura ubwayo nu mukoresha wa nyuma. Irashobora gushyirwa muburyo butaziguye ku biro byuhererekanya birangirana no guhanahana kwaho, cyangwa birashobora gushirwa kumpera ya kure.
Igikorwa cyaONUni ugutanga umukoresha-uruhande rwimbere rwurusobe. Irashobora guhuzwa nabakoresha uburyo butandukanye, kandi mugihe kimwe ifite imikorere yo guhindura ifoto yumuriro hamwe nibikorwa byo kubungabunga no gukurikirana. Igikorwa nyamukuru cyaONUni Kurangiza fibre optique kuva iOLT, gutunganya ibimenyetso bya optique no gutanga intera ya serivise kubucuruzi butandukanye, abakoresha ubucuruzi nabakoresha gutura. Umuyoboro wa nyumaONUni Imigaragarire ya optique, kandi uyikoresha amaherezo ni amashanyarazi. Kubwibyo,ONUifite optique / amashanyarazi n'amashanyarazi / optique yo guhindura imikorere. Ifite kandi imikorere ya digitale / igereranya na analog / guhinduranya imibare y'ibiganiro. UwitekaONUisanzwe ishyirwa hafi yumukoresha, kandi aho iherereye ifite ihinduka ryinshi.
Umuyoboro wa Optical Access Network (OAN) ugabanijwemo Umuyoboro wa Optical Network (AON, Umuyoboro wa Optical Network) hamwe na Passive Optical Network (PON, Passive Optica Optical Network) mubijyanye no gukwirakwiza sisitemu.
Imiterere ya topologiya ya optique ya fibre optique yerekeza kuri geometrike itondekanya imirongo yoherejwe. Yerekana imyanya ihuriweho hamwe nuburyo bwo guhuza buri node muri net. Imiterere ya topologiya y'urusobe igira uruhare runini mumikorere y'urusobe, ikiguzi no kwizerwa. Imiterere itatu yibanze ya topologiya ni: bus-bus, imeze impeta ninyenyeri. Kuva iyi, bus-inyenyeri, kabiri-inyenyeri, impeta-ebyiri, bus-bus hamwe nandi mafishi yo gusaba arashobora kuboneka. Buriwese ufite ibiyiranga kandi byuzuzanya.
