Ikoranabuhanga rya GPON (Gigabit-Capable Passive Optical Network) ni tekinoroji yihuta, ikora neza, kandi ifite ubushobozi bunini bwo gukoresha umurongo mugari ukoreshwa cyane muri fibre-to-home (FTTH) optique yo kubona optique. Mu muyoboro wa GPON,OLT (Umurongo wa Optical Line Terminal)na ONT (Optical Network Terminal) nibintu bibiri byingenzi bigize ibice. Buri wese afite inshingano zitandukanye kandi agakorera hamwe kugirango yihute kandi yihuse.
Itandukaniro riri hagati ya OLT na ONT ukurikije aho uherereye nu mwanya uhagaze: Ubusanzwe OLT iherereye hagati y'urusobe, ni ukuvuga ibiro bikuru, ikina inshingano za "komanda". Ihuza ONT nyinshi kandi ishinzwe kuvugana naONTskuruhande rwabakoresha, mugihe uhuza no kugenzura ihererekanyamakuru. Birashobora kuvugwa ko OLT niyo shingiro nubugingo byurusobe rwose rwa GPON. ONT iherereye kumpera yumukoresha, ni ukuvuga kuruhande rwurusobe, ikina uruhare rw "umusirikare". Nigikoresho kuruhande rwumukoresha wa nyuma kandi gikoreshwa muguhuza ibikoresho bya terefone, nka mudasobwa, TV, router, nibindi, kugirango uhuze abakoresha kumurongo.
Itandukaniro ry'imikorere:OLT na ONT bafite intego zitandukanye. Ibikorwa byingenzi bya OLT birimo gukusanya amakuru, gucunga no kugenzura, kimwe no kohereza no kwakira ibimenyetso bya optique. Irashinzwe gukusanya amakuru aturuka kubakoresha benshi kugirango barebe neza amakuru. Muri icyo gihe, OLT nayo ikorana nizindi OLTs na ONT binyuze muri protocole y'itumanaho gucunga no kugenzura imiyoboro yose. Mubyongeyeho, OLT nayo ihindura ibimenyetso byamashanyarazi mubimenyetso bya optique ikabyohereza muri fibre optique. Mugihe kimwe, irashobora kwakira ibimenyetso bya optique biva kuri ONT ikabihindura mubimenyetso byamashanyarazi kugirango bitunganyirizwe. Igikorwa nyamukuru cya ONT ni uguhindura ibimenyetso bya optique byanyujijwe muri fibre optique mubimenyetso byamashanyarazi no kohereza ibyo bimenyetso byamashanyarazi mubikoresho bitandukanye byabakoresha. Mubyongeyeho, ONT irashobora kohereza, guteranya, no gutunganya ubwoko butandukanye bwamakuru aturuka kubakiriya ikabohereza kuri OLT.
Itandukaniro kurwego rwa tekiniki:OLT na ONT nabo bafite itandukaniro mugushushanya ibyuma na progaramu ya software. OLT isaba imikorere-yimikorere ihanitse, ubushobozi-buke bwo kwibuka, hamwe nintera yihuta kugirango ihangane ninshi muburyo bwo gutunganya amakuru no kohereza. ONT isaba ibyuma byoroshye nibikoresho bya software kugirango bihuze nibyifuzo bitandukanye byabakoresha batandukanye hamwe ninteruro zitandukanye yibikoresho bitandukanye.

OLT na ONT buriwese ashinzwe inshingano zitandukanye mumikorere ya GPON. OLT iherereye hagati y'urusobe kandi ishinzwe gukusanya amakuru, gucunga no kugenzura, kimwe no kohereza no kwakira ibimenyetso bya optique; mugihe ONT iherereye kumpera yumukoresha kandi ishinzwe guhindura ibimenyetso bya optique mubimenyetso byamashanyarazi no kubyohereza mubikoresho byabakoresha. Byombi bikorana kugirango bishoboze umuyoboro wa GPON gutanga serivisi zihuse kandi zinoze zohereza amakuru kugirango uhuze abakoresha ibyo bakeneye mugukoresha umurongo mugari.
