Izibonelelo ezongezelelweyo

I-Fiber optics, nayo i-spelled fibre optics, iinzululwaziyeukuhambisaidatha, ilizwi, kunye nemifanekiso ngokudlula kokukhanya ngeentsinga ezincinci, ezicacileyo.Kwiuthungelwano ngomnxeba, iteknoloji yefiber optic ithathe indawoubheduucingo phakathiumgama omde umnxebaimigca, kwaye isetyenziselwa ukudibanisaiikhompyuthangaphakathiuthungelwano lwengingqi.Ifayibhaopticsikwasisiseko sefiberscopes ezisetyenziswa ekuhloleni amalungu angaphakathi omzimba (i-endoscopy) okanye ukuhlola izinto zangaphakathi zeemveliso ezenziweyo.

Umthombo osisiseko wefiber optics lunwele olubhityileyo lwefiber okwenziwa ngalo ngamanye amaxeshaiplastikikodwa amaxesha amaninziiglasi.I-glass optical fiber eqhelekileyo inobubanzi obuyi-125 micrometres (μm), okanye i-0.125 mm (0.005 intshi).Oku eneneni ubukhulu bomgquba, okanye umaleko obonisa umphandle.I-core, okanye i-internal transmitting cylinder, ingaba ne-diameter encinci njenge-10μm.Ngenkqubo eyaziwa ngokubaukubonakaliswa kwangaphakathi ngokupheleleyo,ukukhanyaimitha yabengezela kwitoti yefiberAndisangaphakathi kumbindi wemigama emide ngokuthomalalisa okuncinci ngokumangalisayo, okanye ukuncipha kobunzulu.Umgangatho wokuthomalalisa kumgama uyahluka ngokobude bokukhanya kunye neukwakhekayefiber.

Xa imicu yeglasi yoyilo/uyilo lokugquma yaziswa ekuqaleni kweminyaka yoo-1950, ubukho bobumdaka banqanda ukuqeshwa kwabo kubude obufutshane obaneleyo kwi-endoscopy.Ngowe-1966, iinjineli zombaneCharles Kaokunye noGeorge Hockham, osebenza eNgilani, bacebisa ukuba kusetyenziswe imicu yeuthungelwano ngomnxeba, yaye kwisithuba seminyaka engamashumi amabinii-silicaImicu yeglasi yayiveliswa ngobunyulu obaneleyoi-infrarediimpawu zokukhanya zazihamba kuzo umgama oziikhilomitha ezili-100 (iikhilomitha ezingama-60) okanye ngaphezulu ngaphandle kokuba ziphakanyiswe ngabantu abaphindayo.Ngo-2009 uKao wawongwa iIbhaso leNobelkwiFiziksi ngomsebenzi wakhe.Iifiber zeplastiki, ezihlala zenziwe nge-polymethylmethacrylate,polystyrene, okanyepolycarbonate, zixabiso eliphantsi ukuvelisa kwaye zibhetyebhetye ngakumbi kunemicu yeglasi, kodwa ukuncitshiswa kwazo okukhulu kokukhanya kuthintela ukusetyenziswa kwazo kumakhonkco amafutshane kakhulu kwizakhiwo okanyeiimoto.

I-Optical telecommunication idla ngokuqhutywa ngei-infraredukukhanya kuluhlu lwamaza e-0.8–0.9 μm okanye 1.3–1.6 μm—amaza obude abenziwa ngokufanelekileyoiidiode ezikhupha ukukhanyaokanyeisemiconductor iilaserkwaye ifumana ubunzima obuncinci kwimicu yeglasi.Ukuhlolwa kweFiberscope kwi-endoscopy okanye kwishishini lenziwa kubude obubonakalayo, inyanda yeentsinga isetyenziselwakhanyisaindawo evavanyiweyo enokukhanya kunye nenye inyanda esebenza njengendeilensiyokuhambisa umfanekiso kwiiliso lomntuokanye ikhamera yevidiyo.

Abamkeli beFiber optic baguqula imiqondiso yokukhanya ibe ziimpawu zombane ukuze zisetyenziswe zizixhobo ezifana nothungelwano lwekhompyutha.Ezi zixhobo ze-electro-optical ziquka i-optical detector, i-amplifier yomsindo ophantsi, kunye ne-signal conditioning circuitry.Emva kokuba i-detector ye-optical iguqule i-optical signal engenayo kwi-signal yombane, i-amplifier iyandisa kwinqanaba elilungele ukulungiswa kwesignali eyongezelelweyo.Uhlobo lokumodareyitha kunye neemfuno zokuphuma kombane zimisela ukuba yeyiphi enye isekethe efunekayo.

Abafumana i-Fiber optic zisebenzisa i-positive-negative junctions (PN), i-positive-intrinsic negative (i-PIN) iifotodiodes, okanye i-avalanche photodiodes (APD) njenge-optical detectors.Isignali yokukhanya engenayo ithunyelwa yi-fiber optic transmitter (okanye i-transceiver) kwaye ihamba nge-single-mode okanye i-multi-mode optical cable, kuxhomekeke kubuchule besixhobo.Idemodulator yedatha iguqula umqondiso wokukhanya ubuyele kwimo yawo yombane.Kwiinkqubo eziyinkimbinkimbi ze-fiber optic, amacandelo e-wavelength division multiplexing (WDM) asetyenziswa kwakhona.

IiSemiconductors kunye neeFotodiode

I-database ye-Engineering360 SpecSearch ivumela abathengi bamashishini ukuba bakhethe iimveliso ngohlobo lwe-semiconductor kunye nohlobo lwe-photodiode.Iintlobo ezimbini ze-semiconductors zisetyenziswa kwi-fiber optic receivers.

I-Silicon semiconductors isetyenziswa kwi-short-wavelength receivers kunye noluhlu lwe-400 nm ukuya kwi-1100 nm.

I-Indium gallium arsenide semiconductors isetyenziswa kwi-long-wavelength receivers kunye noluhlu lwe-900 nm ukuya kwi-1700 nm.

Njengoko kuchaziwe ngasentla, abamkeli befiber optic basebenzisa iintlobo ezintathu ezahlukeneyo zeefotodiode.

Iindibano ze-PN zenziwe kumda we-P-uhlobo kunye ne-N-uhlobo lwe-semiconductor, ngokuqhelekileyo kwikristale enye nge-doping.

I-PIN photodiode inommandla omkhulu, ongenacala-doped wangaphakathi ophakathi kwemimandla ye-P-doped kunye ne-N-doped semiconducting.

Ii-APD ziifotodiodi ze-PIN ezikhethekileyo ezisebenza ngombane ophezulu wokungakhethi cala.

Izikhulisi kunye neziqhagamshelo

Abamkeli beFiber optic basebenzisa i-impedance ephantsi okanye i-transimpedance amplifiers.

Ngezixhobo eziphantsi kwe-impedance, i-bandwidth kunye ne-receiver ingxolo iyancipha ngokuchasana.

Ngezixhobo ze-trans-impedance, i-bandwidth ye-receiver ichaphazeleka kukuzuza kwe-amplifier.

Ngokuqhelekileyo, abamkeli befiber optic baquka iadaptha esusekayo yoqhagamshelo kwezinye izixhobo.Ukhetho lubandakanya i-D4, i-MTP, i-MT-RJ, i-MU, kunye ne-SC

Ukusebenza koMmkeli

Xa usebenzisa i-Engineering360 ukuvelisa iimveliso, abathengi kufuneka bachaze ezi parameters zefiber optic receiver performance.

Ireyithi yedatha linani lamasuntswana athunyelwa ngesekhondi, kwaye luphawu lwesantya.

Ixesha lokunyuka kwe-receiver likwabonakalisa isantya, kodwa libonisa ixesha elifunekayo ukuze umqondiso utshintshe ukusuka kwi-10% ukuya kwi-90% yamandla.

Uvakalelo lubonisa olona phawu lubuthathaka lunokufunyanwa sisixhobo.

Uluhlu lweDynamic lunxulumene novakalelo, kodwa lubonisa uluhlu lwamandla esisebenza phezu kwawo isixhobo.

Ukuphendula ngumlinganiselo wamandla akhazimlayo kwiiwatts (W) ukuya kwisiphumo sefotocurrent kwiiampere (A).
