Umucyo tumenyereye cyane birumvikana ko urumuri dushobora kubona n'amaso.Amaso yacu yumva cyane urumuri rwumutuku rufite uburebure bwa 400nm kugeza itara ritukura kuri 700nm.Ariko kuri fibre optique itwara fibre yibirahure, dukoresha urumuri mukarere ka infragre.Amatara afite uburebure burebure, kwangirika gake kuri fibre optique, kandi ntibigaragara kumaso.Iyi ngingo izaguha ibisobanuro birambuye byuburebure bwa fibre optique n'impamvu ugomba guhitamo ubu burebure.
Igisobanuro cyuburebure
Mubyukuri, urumuri rusobanurwa nuburebure bwarwo.Uburebure bwumubare numubare ugereranya urumuri.Inshuro, cyangwa ibara, ya buri mucyo ifite uburebure bwumurongo ujyanye nayo.Uburebure n'umurongo bifitanye isano.Muri rusange, imirasire ngufi igaragazwa nuburebure bwayo, mugihe imirasire miremire igaragazwa ninshuro zayo.
Uburebure busanzwe muri fibre optique
Ubusanzwe uburebure bwumurambararo ni 800 kugeza 1600nm, ariko nkubu, uburebure bukoreshwa cyane muri fibre optique ni 850nm, 1300nm na 1550nm.Fibre ya Multimode ikwiranye nuburebure bwa 850nm na 1300nm, mugihe fibre yuburyo bumwe ikoreshwa neza kuburebure bwa 1310nm na 1550nm.Itandukaniro riri hagati yuburebure bwa 1300nm na 1310nm riri mwizina risanzwe.Lazeri na diode zisohora urumuri nazo zikoreshwa mugukwirakwiza urumuri muri fibre optique.Lazeri ni ndende kuruta ibikoresho byuburyo bumwe bifite uburebure bwa 1310nm cyangwa 1550nm, mugihe diode itanga urumuri ikoreshwa mubikoresho byinshi bifite uburebure bwa 850nm cyangwa 1300nm.
Kuki uhitamo ubu burebure?
Nkuko byavuzwe haruguru, uburebure bukoreshwa cyane muri fibre optique ni 850nm, 1300nm na 1550nm.Ariko kuki duhitamo ubu burebure butatu bwumucyo?Ni ukubera ko ibimenyetso bya optique byubu burebure butatu bifite igihombo gito iyo byanduye muri fibre optique. Kubwibyo rero birakwiriye cyane nkisoko yumucyo iboneka yo kwanduza fibre optique. Gutakaza fibre yibirahure ahanini biva mubice bibiri: gutakaza kwinjiza no gutakaza igihombo. Igihombo cya Asorption kiboneka cyane cyane muburebure bwihariye bwumurongo twita "imiyoboro y'amazi", cyane cyane bitewe no kwinjiza ibitonyanga byamazi yibirahuri mubirahuri.Gutatana ahanini biterwa no kongera kwa atome na molekile ku kirahure.Ikwirakwizwa rirerire ni rito cyane, iyi niyo mikorere nyamukuru yuburebure.
Mu gusoza
Nyuma yo gusoma iyi ngingo, ushobora kuba ufite ubumenyi bwibanze bwuburebure bwumurongo ukoreshwa muri fibre optique.Kuberako gutakaza umurongo wa 850nm, 1300nm na 1550nm biri hasi cyane, nibyiza guhitamo itumanaho rya fibre optique.
