Sobanukirwa n'uburebure bwa 850nm, 1310nm na 1550nm muri fibre optique

Umucyo usobanurwa nuburebure bwacyo, no mubitumanaho bya fibre optique, urumuri rukoreshwa ruri mukarere ka infragre, aho uburebure bwumucyo buruta ubw'urumuri rugaragara.Mu itumanaho rya fibre optique, uburebure bwumuraba ni 800 kugeza 1600nm, naho uburebure bukoreshwa cyane ni 850nm, 1310nm na 1550nm.

Inkomoko y'amashusho:

Iyo fluxlight ihitamo imiyoboro yumurongo, itekereza cyane cyane kubura fibre no gutatana.Intego ni ugukwirakwiza amakuru menshi hamwe no gutakaza fibre nkeya intera ndende.Gutakaza imbaraga za signal mugihe cyo kohereza ni attenuation.Kwiyegereza bifitanye isano n'uburebure bwa flimform, igihe kirekire cyumuraba, ntoya.Umucyo ukoreshwa muri fibre ufite uburebure burebure kuri 850, 1310, 1550nm, bityo rero kwiyongera kwa fibre ni bike, bikaviramo no gutakaza fibre nkeya.Kandi ubu burebure butatu bufite hafi ya zeru zinjira, zikwiranye cyane no kwanduza fibre optique nkisoko yumucyo iboneka.

Inkomoko y'amashusho:

Mu itumanaho rya fibre optique, fibre optique irashobora kugabanwa muburyo bumwe nuburyo bwinshi.Agace k'uburebure bwa 850nm mubusanzwe nuburyo bwinshi bwo guhuza itumanaho rya fibre optique, 1550nm nuburyo bumwe, naho 1310nm ifite ubwoko bubiri bwuburyo bumwe nuburyo bwinshi.Urebye kuri ITU-T, kwiyongera kwa 1310nm birasabwa kuba ≤0.4dB / km, naho kwiyongera kwa 1550nm ni ≤0.3dB / km.Kandi igihombo kuri 850nm ni 2.5dB / km.Gutakaza fibre muri rusange bigabanuka uko uburebure bwumurongo bwiyongera.Uburebure bwo hagati ya 1550 nm hafi ya C-band (1525-1565nm) mubisanzwe byitwa idirishya rya zero, bivuze ko kwiyegereza fibre ya quartz ari ntoya kuri ubu burebure.

Beijing Rofea Optoelectronics Co., Ltd iherereye mu Bushinwa “Silicon Valley” - Beijing Zhongguancun, ni ikigo cy’ikoranabuhanga rikomeye cyahariwe gukorera ibigo by’ubushakashatsi mu gihugu no mu mahanga, ibigo by’ubushakashatsi, kaminuza ndetse n’abakozi bashinzwe ubushakashatsi mu bumenyi.Isosiyete yacu ikora cyane cyane mubushakashatsi niterambere byigenga, gushushanya, gukora, kugurisha ibicuruzwa bya optoelectronic, kandi bitanga ibisubizo bishya hamwe na serivise zumwuga, zihariye kubashakashatsi ba siyanse n'abashinzwe inganda.Nyuma yimyaka myinshi yo guhanga udushya, yakoze urukurikirane rwinshi kandi rwuzuye rwibicuruzwa byamashanyarazi, bikoreshwa cyane mumijyi, igisirikare, ubwikorezi, amashanyarazi, imari, uburezi, ubuvuzi nizindi nganda.
