Umuyoboro wa optique ni umuyoboro winjira ukoresha urumuri nkuburyo bwo kohereza, gusimbuza insinga z'umuringa, kandi bikoreshwa muri buri rugo. Umuyoboro mwiza wa optique muri rusange ugizwe nibice bitatu: umurongo wa optiqueOLT, Umuyoboro wa optiqueONU, hamwe na optique yo gukwirakwiza umuyoboro ODN, aho ibice byingenzi bigizeOLTnaONUumuyoboro mwiza.
NikiOLT?
Izina ryuzuye ryaOLTni Optical Line Terminal, optique yumurongo wanyuma.OLTni umurongo wa optique, kandi ni ibikoresho byo mu biro bikuru byitumanaho. Byakoreshejwe muguhuza optique ya fibre optique. Ikora nka ahindura or Routermurusobe rwitumanaho gakondo. Nigikoresho cyo kwinjirira mumurongo wo hanze no kwinjira no gusohoka kwurusobe rwimbere. Bishyizwe ku biro bikuru, ibikorwa byingenzi byogukora ni gahunda yumuhanda, kugenzura buffer, no gutanga abakoresha-bayobora pasiporo optique ya interineti no gutanga umurongo. Mumagambo yoroshye, ashyira mubikorwa imirimo ibiri: hejuru, yuzuza uburyo bwo kugera kumurongo wa PON; no kumanuka, yohereza amakuru yabonetse kuri boseONUukoresha ibikoresho bya terefone ukoresheje umuyoboro wa ODN.
NikiONU?
ONUni Optical Network Unit. UwitekaONUifite imirimo ibiri: Hitamo kwakira ibiganiro byoherejwe naOLT, kandi wakire igisubizo kuriOLTniba amakuru akeneye kwakirwa; gukusanya no kubika amakuru ya Ethernet umukoresha akeneye kohereza, no kohereza kuriOLTukurikije idirishya ryoherejwe ryohereze Kohereza amakuru yabitswe.

ONT ni iki?
ONT ni Optical Network Terminal, igice cyanyuma cya FTTH, gikunze kwitwa "injangwe optique", gisa ninjangwe yamashanyarazi ya xDSL. ONT numuyoboro wa optique kandi ikoreshwa kubakoresha amaherezo.ONUbivuga umurongo wa optique. Hashobora kubaho indi miyoboro hagati yayo nu mukoresha wa nyuma. ONT ni igice cyingenzi cyaONU.
Ni irihe sano riri hagatiONUnaOLT?

ODN ni iki?
ODN ni Optical Ikwirakwiza, ni umuyoboro wumubiri wo kohereza optique hagatiOLTnaONU. Igikorwa nyamukuru nukuzuza ibyerekezo byombi byohereza ibimenyetso bya optique. Mubisanzwe ibyo bihujwe ninsinga za fibre optique, ihuza optique, ibice bya optique, hamwe nogushiraho. Ibikoresho bifasha igikoresho bigizwe na optique itandukanya.
