OLT ni iki?

Izina ryuzuye rya OLT ni Optical Line Terminal, umurongo wa optique.OLT ni umurongo wa optique hamwe nibikoresho byo mu biro bikuru byitumanaho.Byakoreshejwe muguhuza optique fibre trunk imirongo.Ikora nka switch cyangwa router murusobe rwitumanaho gakondo.Nigikoresho ku bwinjiriro bwurusobe rwo hanze no kwinjirira murusobe rwimbere.Bishyizwe ku biro bikuru, ibikorwa byingenzi byubuyobozi ni gahunda yo gutondekanya umuhanda, kugenzura buffer, no gutanga abakoresha-bayobora pasiporo optique ya interineti hamwe nogutanga umurongo.Kubivuga mu buryo bworoshye, ni ukugera kubikorwa bibiri.Kuri upstream, irangiza hejuru yo kugera kumurongo wa PON;kumurongo wo hasi, amakuru yabonetse yoherejwe kandi akwirakwizwa kubikoresho byose byabakoresha ONU binyuze mumurongo wa ODN.

ONU ni iki?

ONU ni Optical Network Unit.ONU ifite imirimo ibiri: ihitamo kwakira ibiganiro byoherejwe na OLT, kandi igasubiza OLT niba amakuru akeneye kwakirwa;ikusanya kandi ikanabika amakuru ya Ethernet uyikoresha akeneye kohereza, akayohereza muri OLT ukurikije idirishya ryoherejwe ryohereze Kohereza amakuru yabitswe.

Mumuyoboro wa FTTx, uburyo butandukanye bwo kohereza ONU uburyo butandukanye nabwo buratandukanye, nka FTTC (Fibre To The Curb): ONU ishyirwa mubyumba bya mudasobwa nkuru yabaturage;FTTB (Fibre Kuri Inyubako): ONU ishyirwa muri koridor FTTH (Fibre Kuri Murugo): ONU ishyirwa mumukoresha murugo.
