Mwaramutse, Basomyi.Muri iyi ngingo ngiye kuganira kuri OSI-Data Ihuza Ihuza Ikosa Igenzura hamwe nibisobanuro.Reka dutangire…
Kugirango wumve ihererekanyamakuru ryihuza ryamakuru reka dufate urugero, niba igikoresho gikeneye kuvugana nigikoresho B, guhuza itumanaho hamwe nuruhererekane rwibikoresho.Niba umurongo wose w'itumanaho udafite uburyo bwo kugenzura amakosa, noneho amakuru yoherejwe na A azoherezwa na B. Niba hari uburyo bwo kugenzura amakosa kumurongo w'itumanaho, amakuru yoherejwe kuva A kugeza kuri B azamenyekana nka an ikosa ku gikoresho cyegereye A, na A gikeneye koherezwa nanone, kandi ikadiri yukuri irashobora koherezwa mbere.Niba yoherejwe kuruhande rwa B, noneho umurongo wose urashobora kubika umutungo, aribwo buryo bwo kugenzura amakosa yuburyo bwamakuru.
Igenzura ryamakosa yamakuru ahuza igamije ahanini kwibeshya kuri bito.Hariho uburyo bubiri bwo kugenzura, bugabanijwemo kode yo kumenya amakosa no gukosora amakosa.Kode yo kumenya amakosa ikubiyemo uburinganire na cyclic redundancy CRC, mugihe code yo gukosora amakosa irimo code ya Nyundo.
Kwandika no guhinduranya umurongo uhuza urwego rwumubiri biratandukanye.Igice gifatika nikintu kimwe kugirango gikemure ikibazo cyo guhuza biti mugikorwa cyo kohereza, nka code ya Manchester.Kode ya data ihuza urwego igamije gushiraho amakuru ya biti, kandi ikamenya kugenzura ikosa ryagenzuwe ryuruhererekane rwibintu bibiri muburyo bwo kohereza hakoreshejwe ikoranabuhanga rya kode.
Ibyavuzwe haruguru nubusobanuro bwubumenyi bwa "OSI-Data Link Layer-Error Control" yazanwe na Shenzhen Shenzhen HDV ifoto yumuriro wa tekinoroji, Ltd Ibicuruzwa byitumanaho byakozwe na sosiyete bitwikiriye;Ibyiciro by'amasomo:moderi ya fibre optique, Ethernet, optique fibre transceiver modules, optique ya fibre optique, 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.
Ishuri rya OLT: 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 twandikire
