Igisobanuro: Impeta ya Firisitu Impeta zinyuramo urumuri inshuro nyinshi

Impeta ya fiblic ni aIgikoresho cya Fibre OpticNimuricyo urumuri rushobora gusubira inyuma inshuro nyinshi. Ikoreshwa cyane cyane mugihe kirekire cya fibre ya fibre ya fibre. Ndetse n'uburebure bwa nyumaFibre, urumuri rwikimenyetso rushobora kwandura intera ndende cyane ruhinduranya inshuro nyinshi. Ibi bifasha kwiga ingaruka mbi no kudasobanura neza bigira ingaruka kumiterere yoroheje yikimenyetso.

Muri tekinoroji ya Laser, imigozi ya Cyclic irashobora gukoreshwa mugupima umurongo wa alaser, cyane cyane iyo umurongo ari muto cyane (<1khz). Iri ni ryo ryagutse uburyo bwo kwiyitirira OrWerodyne OrWedth, budasaba inyongera ya laser kugirango ubone ibimenyetso byerekana ubwabyo, bisaba gukoresha fibre imwe. Ikibazo hamwe na tekinoroji yo kumenya tekinoroji ni uko igihe gisabwa cyatinze ari kimwe muri gahunda imwe nu redocal yumurongo wa kabiri, kugirango ubugari bwumurongo ari bike gusa.

Igishushanyo 1: Igishushanyo cya Schematic cyumpeta ya fiblic.

Impamvu y'ibanze yo gukoresha imirongo ya fibre nuko fibre isanzwe ishobora gutanga igihe kirekire kuko urumuri rwinshi ruhinduka fibre. Kugirango dutandukane urumuri rwatangwa muburyo butandukanye, modulator ya acousto-optique irashobora gukoreshwa mumuzingo kugirango itange imirongo runaka (kurugero, 100mhz). Kuberako iyi mpindo ya frequency nini cyane kuruta ubugari bwumurongo, urumuri rwagenze kumurongo utandukanye muri loop urashobora gutandukana murwego rwinshi. MuriPhotodetetector, umwimerereitara rya laserKandi gukubita urumuri nyuma yo guhindura imirongo birashobora gukoreshwa mugupima ubugari.

Niba nta gikoresho cyongerewe mu muzingo, igihombo muri modulator ya acousto na fibre na fibre nini cyane, kandi ubukana bworoshye buzabohorana uburemere nyuma yisi yose. Ibi bigabanya cyane umubare wimirongo mugihe umuhuza yapimwe. Amplifiers fibre irashobora kongerwa kumuzingi kugirango ukureho iyi mbogamizi.

Ariko, ibi bitera ikibazo gishya: Nubwo urumuri runyuramo rutandukanye rwose, ibimenyetso byo gukubita biva mubice bitandukanye byamafoto, bihindura speccrum muri rusange. Impeta ya fibre ya optique irashobora kuba igamije kubuza neza izi ngaruka. Hanyuma, kwiyumvisha kwa Cyclic fibre loop igarukira ku rusaku rwafibre amplifier. Birakenewe kandi gusuzuma niba fibre hamwe nimirongo itari lorentz muburyo bwo gutunganya amakuru
