Hamwe nogutezimbere kwiterambere ryumuyoboro mugari, iterambere rihoraho ryibikoresho bya terefone, ibiganiro bisobanurwa cyane kuri videwo, serivisi zicu, guhanahana amakuru, ibiro bigendanwa, nibindi, ibigo bigenda neza kandi bifungura urubuga, bityo biteza imbere ibiro byubwenge namakuru. by'ibigo, n'ibisabwa kugirango umuyoboro mugari n'umuvuduko bigenda birushaho kuba hejuru.Ikigo gisanzwe hamwe na Lans ya campus Lans ifite icyifuzo cyo kuzamura imiyoboro mugihe ihuye nikibazo kinini cyumurongo uva muribi bikorwa.
Ibigize urusobe rwiza rwose
POL ikoresha tekinoroji ya PON, Passive Optical Network (PON) ni point-to-point point (P2MP) Passive Optical Network, igizwe na OLT (LM808E), ODN, na ONT.
POL (Passive Optical LAN) Passive all-optique LAN
Mumuyoboro wa POL, guhinduranya ibintu muri LAN gakondo bisimburwa na OLT (LM808E).Umugozi wumuringa utambitse usimburwa na fibre optique;Kwinjira byinjira byasimbuwe na pasitiki optique itandukanya.
ONT itanga imikorere ya layer 2 cyangwa Layeri 3 kugirango igere kumakuru yabakoresha, amajwi, na videwo binyuze mumashanyarazi cyangwa insinga.
PON net downlink ifata uburyo bwo gutangaza: ibimenyetso bya optique byoherejwe na OLT (LM808E) bigabanijwemo ibimenyetso byinshi bya optique hamwe namakuru amwe binyuze mumashanyarazi kandi byoherejwe kuri buri ONT; ONT ihitamo kwakira udupaki twayo dushingiye kubirango biri mubipaki. akirukana abafite Tag idahuye.
Uplink icyerekezo cyumuyoboro wa PON: OLT (LM808E) itanga igice cyigihe kuri buri ONT.ONT yohereza ibimenyetso byimazeyo ukurikije iki gihe cyaciwe kandi igahagarika icyambu cya optique ukurikije igice cyigihe kitari icyawo.Uplink igihe idirishya ryingengabihe iterwa cyane nubuhanga buringaniye bwa PON.
Gusobanukirwa ihame rya tekinoroji ya PON bidufasha gukoresha ubu buhanga muburyo bwubuhanga mugushushanya amashanyarazi, cyane cyane passiyo (nta mashanyarazi) iranga imiyoboro yo gukwirakwiza optique, kandi itandukaniro riri hagati yimiterere gakondo yo gukwirakwiza ibintu byumwihariko dukeneye kwitondera .Kwemeza ko paki zumuhanda mubyerekezo bibiri zoherejwe kuri fibre imwe yibanze, PON ifata uburyo bwo kugabana imiraba.Nyuma yiterambere kugeza 10 Gigabit PON, ibice bine byuburebure bikoreshwa mugukoresha fibre optique.
Isi nziza, Umuti wa Limee!Reka dukomeze ibiganiro byacu kuri optique yisi yose ubutaha.
