Igice gifatika kiri munsi yicyitegererezo cya OSI, kandi umurimo wacyo wingenzi ni ugukoresha uburyo bwo kohereza ibintu kugirango utange umurongo uhuza amakuru kugirango uhuze biti.Igice gifatika gisobanura uburyo umugozi uhujwe namakarita y'urusobe, hamwe nubuhanga bwogukwirakwiza bugomba gukoreshwa kugirango wohereze amakuru kuri kabili, kandi busobanura uburyo bwo kugera kumurongo wo hejuru (data ihuza layer).
Mubisanzwe, ibikoresho bifite amakuru amwe yo gutunganya no kohereza no kwakira ubushobozi byitwa data terminal ibikoresho (DTE), naho ibikoresho hagati ya DTE nuburyo bwo kohereza byitwa ibikoresho byuzuza amakuru (DCE).DCE itanga ibimenyetso byo guhindura no guhuza ibikorwa hagati ya DTE nogukwirakwiza, kandi ishinzwe gushiraho, kubungabunga no kurekura imiyoboro ifatika.Kuberako DCE iri hagati ya DTE nuburyo bwo kohereza, mugihe cyitumanaho, DCE yohereza amakuru ya DTE muburyo bwo kohereza ku ruhande rumwe, kurundi ruhande, ikeneye kohereza biti yakiriwe kuva kuri uburyo bwo kohereza kuri DTE bikurikiranye..
Kandi iki gipimo gisobanura ibintu bine biranga urwego rwumubiri:
1. Ibiranga imashini: Sobanura ibiranga guhuza umubiri, vuga ibisobanuro, imiterere yimbere, umubare wuyoboye, umubare no gutondekanya pin zikoreshwa muguhuza umubiri, nibindi.
2. Ibiranga amashanyarazi: Mugihe hagaragajwe ihererekanyabubasha ryibice bibiri, urwego rwa voltage, guhuza inzitizi, igipimo cyogukwirakwiza nintera ntarengwa yikimenyetso kumurongo, nibindi.
3. Ibiranga imikorere: erekana icyo igisobanuro cyurwego runaka kumurongo runaka bivuze, nintego yumurongo wibimenyetso udafite isura itagaragara
4. Ibiranga inzira (ibiranga inzira): gusobanura inzira zakazi nubusabane bwigihe cya buri muzunguruko
Ibyavuzwe haruguru nubusobanuro bwubumenyi bwa "OSI-Physical Layer Characteristics" yazanwe na Shenzhen HDV ifoto y’amashanyarazi y’ikoranabuhanga, Ltd Ibicuruzwa byitumanaho byakozwe na sosiyete:
Ibyiciro by'amasomo: moderi ya fibre optique, Ethernet, optique fibre transceiver modules, optique ya fibre igera module, SSFP optique module, naSFP optique, n'ibindi.
Icyiciro cya ONU: EPON ONU, AC ONU, fibre optique ONU, CATV ONU, GPON ONU, XPON ONU, n'ibindi.
Icyiciro cya kera: OLT, GPON OLT, EPON OLT, itumanaho OLT, nibindi
Ibicuruzwa byavuzwe haruguru birashobora gutanga inkunga kubintu bitandukanye byurusobe.Itsinda ryinzobere kandi rikomeye R&D rirashobora gufasha abakiriya bafite ibibazo bya tekiniki, kandi itsinda ryubucuruzi ryatekereje kandi ryumwuga rirashobora gufasha abakiriya kubona serivise nziza mugihe cyo kubanziriza inama ndetse nakazi nyuma yumusaruro.Murakaza neza kuri twandikireKuriubwoko ubwo aribwo bwose.
