Sobanukirwa uburebure bw'urumuri rwa 850nm, 1310nm na 1550nm muri fibre optique
Umucyo ugaragazwa n'uburebure bwawo, kandi mu itumanaho rya fibre optique, urumuri rukoreshwa ruri mu gace ka infrared, aho uburebure bw'urumuri buruta ubw'urumuri rugaragara. Mu itumanaho rya fibre optique, uburebure busanzwe ni 800 kugeza 1600nm, naho uburebure bukunze gukoreshwa ni 850nm, 1310nm na 1550nm.

Iyo urumuri rw'umurambararo ruhisemo uburebure bw'umurambararo, ahanini rureba igihombo cya fibre no gukwirakwira. Intego ni ugutanga amakuru menshi hamwe n'igihombo gito cya fibre mu ntera ndende. Igihombo cy'imbaraga z'ikimenyetso mu gihe cyo kohereza ni ugutakaza. Gutakaza bifitanye isano n'uburebure bw'imiterere y'umurambararo, uko imiterere y'umurambararo iba miremire, niko gutakaza guto. Urumuri rukoreshwa muri fibre rufite uburebure bw'umurambararo kuri 850, 1310, 1550nm, bityo gutakaza fibre ni bike, ibyo bikaba binatuma fibre itakaza guto. Kandi izi ngero eshatu z'umurambararo zifite hafi ya zeru zo kwinjiza, zikwiriye cyane kohereza muri fibre z'urumuri nk'amasoko y'urumuri aboneka.

Mu itumanaho rya fibre optique, fibre optique ishobora kugabanywamo uburyo bumwe n'uburyo bwinshi. Agace k'uburebure bwa 850nm ubusanzwe ni uburyo bwo itumanaho bwa fibre optique bw'uburyo bwinshi, 1550nm ni uburyo bumwe, naho 1310nm ifite ubwoko bubiri bwa single-mode n'uburyo bwinshi. Tuvuze kuri ITU-T, kugabanya 1310nm byasabwa kuba ≤0.4dB/km, naho kugabanya 1550nm ni ≤0.3dB/km. Kandi kugabanuka kuri 850nm ni 2.5dB/km. Kugabanuka kwa fibre muri rusange kugabanuka uko ubunini bw'uburebure bwiyongera. Ubunini bw'uburebure bwa 1550 nm bukikije C-band (1525-1565nm) busanzwe bwitwa zero loss window, bivuze ko kugabanya uburebure bwa fibre quartz ari bwo buto kuri ubu burebure.
Beijing Rofea Optoelectronics Co., Ltd. iherereye mu "Silicon Valley" mu Bushinwa - Beijing Zhongguancun, ni ikigo cy’ikoranabuhanga rigezweho cyihaye inshingano zo gukorera ibigo by’ubushakashatsi byo mu gihugu no mu mahanga, ibigo by’ubushakashatsi, za kaminuza n’abakozi b’ubushakashatsi bwa siyansi mu bigo. Isosiyete yacu ikora cyane cyane ubushakashatsi bwigenga n’iterambere, gushushanya, gukora, kugurisha ibicuruzwa bya optoelectronic, kandi itanga ibisubizo bishya na serivisi z’umwuga ku bashakashatsi ba siyansi n’abahanga mu nganda. Nyuma y’imyaka myinshi y’udushya twigenga, yakoze urukurikirane rw’ibicuruzwa bikungahaye kandi byuzuye by’amashanyarazi, bikoreshwa cyane mu nganda z’umujyi, iza gisirikare, ubwikorezi, ingufu z’amashanyarazi, imari, uburezi, ubuvuzi n’izindi nganda.
