amenya itumanaho rya fibre optique rishingiye ku ihame ryo kwerekana urumuri rwose.
Iyo urumuri rukwirakwira hagati ya fibre optique, indangagaciro yo kwanga n1 ya fibre fibre iba hejuru kurenza iyambitswe n2, kandi gutakaza intandaro biri munsi yuwambaye, kugirango urumuri ruzagaragare rwose , n'imbaraga zayo zoroheje zoherezwa cyane muri rusange. Bitewe nibitekerezo bikurikiranye, urumuri rushobora kwanduzwa kuva kuruhande rumwe kurundi.
Bishyizwe muburyo bwo kohereza: uburyo-bumwe nuburyo bwinshi.
Imiterere-imwe ifite diameter ntoya kandi irashobora kohereza urumuri rwumucyo muburyo bumwe.
Ubwoko bwinshi bwa optique fibre ifite diameter nini kandi irashobora kohereza urumuri rwinshi muburyo bwinshi.
Turashobora kandi gutandukanya fibre imwe ya optique fibre na fibre optique ya fibre yuburyo bwibara.
Byinshi muburyo bumwe bwa optique fibre ifite ikoti yumuhondo hamwe nubururu bwubururu, naho insinga ya kabili ni 9.0 mm. Hariho uburebure bubiri hagati ya fibre imwe-fibre imwe: 1310 nm na 1550 nm. 1310 nm muri rusange ikoreshwa muguhuza intera ngufi, intera ndende cyangwa intera ndende, na 1550 nm ikoreshwa mugukwirakwiza intera ndende na ultra-ndende. Intera yohereza iterwa nimbaraga zo kohereza za optique module. Intera yo kohereza kuri 1310 nm icyambu kimwe ni 10 km, 30 km, 40 km, nibindi, naho intera yohereza ya 1550 nm icyambu kimwe ni 40 km, 70 km, 100 km, nibindi.
Ubwoko bwinshi bwa fibre optique ni ahanini orange / ikoti ryijimye hamwe na black / beige ihuza, 50.0 μ m na 62.5 mkm. Uburebure bwo hagati bwa fibre yuburyo bwinshi ni 850 nm. Intera yoherejwe ya fibre yuburyo bwinshi ni ngufi, muri m 500.
