Fibre optique, nayo yanditse fibre optique ,.siyanseByakwanduzaamakuru, ijwi, n'amashusho unyuze mumucyo unyuze mumashanyarazi yoroheje.Muriitumanaho, tekinoroji ya fibre optique yasimbuwe hafiumuringawire inIntera ndende telefoneimirongo, kandi ikoreshwa muguhuzamudasobwaimbereimiyoboro y'akarere.Fibreoptiqueni naryo shingiro rya fiberscopes ikoreshwa mugusuzuma ibice byimbere byumubiri (endoskopi) cyangwa kugenzura imbere yibicuruzwa byubatswe byakozwe.

Uburyo bwibanze bwa fibre optique ni fibre yoroheje umusatsi rimwe na rimwe ikozweplastikeariko kenshi na kenshiikirahure.Ubusanzwe fibre optique fibre ifite diameter ya micrometero 125 (μm), cyangwa 0,125 mm (0.005 cm).Nukuri mubyukuri diameter ya cladding, cyangwa hanze yerekana urwego.Intangiriro, cyangwa itumanaho ryimbere, irashobora kugira diameter ntoya nka 10μm.Binyuze mu nzira izwi nkakwigaragaza imbere,urumuriimirasire yamuritse muri fibrekwamamazaimbere muri intera nini cyane hamwe na attenensiya idasanzwe, cyangwa kugabanya ubukana.Urwego rwo kwiyegereza intera iratandukanye ukurikije uburebure bwumucyo no kuriibihimbanoya fibre.

Mugihe ibirahuri bya fibre yibanze / yambitswe igishushanyo cyatangijwe muntangiriro ya 1950, kuba hari umwanda wabuzaga akazi kuburebure buke buhagije kuri endoskopi.Mu 1966, abashakashatsi b'amashanyaraziCharles Kaona George Hockham, ukorera mu Bwongereza, batanze igitekerezo cyo gukoresha fibreitumanaho, no mu myaka mirongo ibirisilikaibirahuri by'ibirahure byakorwaga bifite isuku ihagije koinfraredibimenyetso byoroheje byashoboraga kubanyuramo ibirometero 100 cyangwa birenga bitabaye ngombwa ko byongerwaho nababisubiramo.Muri 2009 Kao yahawe igihembo cyaIgihembo cyitiriwe Nobelmuri Physique kumurimo we.Fibre ya plastike, ikozwe muri polymethylmethacrylate,polystirene, cyangwapolikarubone, bihendutse kubyara kandi byoroshye kuruta fibre yibirahure, ariko kuba urumuri rwinshi rwumucyo rugabanya imikoreshereze yabyo mugufi cyane mumazu cyangwaibinyabiziga.

Itumanaho ryiza risanzwe rikorwa hamweinfraredurumuri mu burebure bwa 0.8-0.9 mm cyangwa 1,3-1,6 mm - uburebure bwumuraba butangwa neza nadiode itanga urumuricyangwaigice cya kabiri laserikandi ibyo bibabazwa cyane na fibre yibirahure.Igenzura rya Fiberscope muri endoscopi cyangwa inganda ikorwa muburebure bugaragara bwumurongo, umugozi umwe wa fibre ikoreshwakumurikaagace kasuzumwe hamwe numucyo nundi bundle ikora nkigihe kirekirelensKuri Kohereza Ishusho Kuriijisho ry'umuntucyangwa kamera ya videwo.

Fibre optique yakira ihindura ibimenyetso byumucyo mubimenyetso byamashanyarazi kugirango ikoreshwe nibikoresho nkurusobe rwa mudasobwa.Ibi bikoresho bya electro-optique bigizwe na optique ya optique, ibyuma byongera urusaku ruke, hamwe na sisitemu yerekana ibimenyetso.Nyuma ya optique ya optique ihindura ibimenyetso byinjira byinjira mubimenyetso byamashanyarazi, amplifier irayongera kurwego rukwiranye no gutunganya ibimenyetso byiyongera.Ubwoko bwa modulisiyo nibisabwa nibisohoka byamashanyarazi bigena ikindi kizunguruka gisabwa.

Fibre optique yakira ikoresha ibyiza-bibi bihuza (PN), fotodiode nziza-nziza (PIN), cyangwa fotodi ya avalanche (APD) nkibikoresho bya optique.Ikimenyetso cyumucyo winjira cyoherejwe na fibre optique yoherejwe (cyangwa transceiver) kandi ikagenda kumurongo umwe cyangwa uburyo bwinshi bwa optique, bitewe nubushobozi bwibikoresho.Data demodulator ihindura ibimenyetso byumucyo muburyo bwamashanyarazi bwambere.Muri sisitemu igoye ya fibre optique, ibice bigabanya umurongo wa WDM) nabyo birakoreshwa.

Semiconductor na Photodiode

Ubwubatsi360 bwihariye bwububiko butuma abaguzi binganda bahitamo ibicuruzwa kubwoko bwa semiconductor nubwoko bwa fotodiode.Ubwoko bubiri bwa semiconductor bukoreshwa muri fibre optique.

Silicon semiconductor ikoreshwa mumashanyarazi magufi-yakira hamwe na 400 nm kugeza 1100 nm.

Indium gallium arsenide semiconductor ikoreshwa mumashanyarazi maremare maremare hamwe na 900 nm kugeza 1700 nm.

Nkuko byasobanuwe haruguru, fibre optique yakira ubwoko butatu bwa fotodiode.

Ihuriro rya PN ryakozwe kumupaka wubwoko bwa P na N-semiconductor, mubisanzwe muri kristu imwe ikoresheje doping.

PIN fotodiode ifite akarere kanini, kidafite aho kibogamiye-kamwe kegeranye hagati yakarere ka P-dope na N-dope semiconducting.

APDs ni Pododi yihariye ya PIN ikorana na voltage ihindagurika.

Amplifiers hamwe nabahuza

Fibre optique yakira ikoresha haba-impedance nkeya cyangwa transimpedance amplifier.

Hamwe nibikoresho bidafite imbaraga, umuvuduko mwinshi hamwe n urusaku rwakira bigabanuka hamwe no guhangana.

Hamwe nibikoresho bya trans-impedance, ubwinshi bwabakiriya bugira ingaruka ku nyungu za amplifier.

Mubisanzwe, fibre optique yakira harimo adaptable ikurwaho kugirango ihuze nibindi bikoresho.Guhitamo birimo D4, MTP, MT-RJ, MU, na SC

Imikorere y'abakira

Mugihe ukoresheje Engineering360 kugirango ubone isoko, abaguzi bagomba kwerekana ibipimo byimikorere ya fibre optique.

Igipimo cyamakuru ni umubare wa bits zoherejwe ku isegonda, kandi ni imvugo yihuta.

Igihe cyo kwakira abashyitsi nacyo kigaragaza umuvuduko, ariko cyerekana igihe gikenewe kugirango ikimenyetso gihindurwe kuva 10% kugeza kuri 90%.

Sensitivity yerekana ibimenyetso bya optique igikoresho gishobora kwakira.

Urwego rudasanzwe rufitanye isano na sensitivite, ariko rwerekana imbaraga urwego igikoresho gikoreramo.

Inshingano ni igipimo cyingufu zumucyo muri watts (W) na Photocurrent yavuyemo muri amperes (A).
