Cov peev txheej ntxiv

Fiber optics, kuj spelled fiber optics, lubkev kawmntawmkis taucov ntaub ntawv, suab, thiab cov duab los ntawm txoj kev ntawm lub teeb los ntawm nyias, pob tshab fibers.Hauvkev sib txuas lus, fiber optic technology tau zoo hloovtooj liabkab innyob deb xov toojkab, thiab nws yog siv los txuaskhoos phis tawjhauvhauv zos networks.Fiber ntauopticstseem yog lub hauv paus ntawm cov fiberscopes siv los tshuaj xyuas qhov chaw hauv lub cev (endoscopy) lossis tshuaj xyuas cov khoom siv sab hauv ntawm cov khoom tsim khoom.

Qhov nruab nrab nruab nrab ntawm fiber ntau optics yog cov plaub hau nyias fiber ntau uas qee zaum ua los ntawmyastab sis feem ntau ntawmiav.Ib tug raug iav optical fiber muaj ib txoj kab uas hla ntawm 125 micrometers (μm), los yog 0.125 hli (0.005 nti).Qhov no yog tiag tiag txoj kab uas hla ntawm cladding, los yog txheej reflecting txheej.Cov tub ntxhais, lossis sab hauv lub tog raj kheej xa tawm, tuaj yeem muaj txoj kab uas hla me me li 10ib m.Los ntawm cov txheej txheem hu uatag nrho internal reflection,teebrays beamed rau hauv fiber ntaunthuav tawmnyob rau hauv lub hauv paus rau kev ncua deb nrog remarkably me ntsis attenuation, los yog txo nyob rau hauv kev siv.Qhov degree ntawm attenuation tshaj qhov deb txawv raws li lub wavelength ntawm lub teeb thiab mus rau qhovmuaj pes tsawg leegntawm fiber.

Thaum cov iav fibers ntawm cov tub ntxhais / cladding tsim tau qhia nyob rau hauv thaum ntxov 1950s, lub xub ntiag ntawm impurities txwv lawv txoj hauj lwm rau luv luv ntev txaus rau endoscopy.Xyoo 1966, hluav taws xob engineersCharles Kaothiab George Hockham, ua haujlwm hauv tebchaws Askiv, pom zoo siv fibers raukev sib txuas lus, thiab nyob rau hauv ob xyoo caumsilicaiav fibers tau raug tsim nrog txaus purity uasinfraredLub teeb ci ntsa iab tuaj yeem hla lawv mus txog 100 km (60 mais) lossis ntau dua yam tsis tas yuav tsum tau txhawb nqa los ntawm cov neeg rov ua dua.Nyob rau hauv 2009 Kao twb muab tsub lubNobel nqi zoghauv Physics rau nws txoj haujlwm.Yas fibers, feem ntau yog ua los ntawm polymethylmethacrylate,polystyrene, los yogpolycarbonate, yog pheej yig dua los tsim thiab hloov pauv ntau dua li cov iav fibers, tab sis lawv qhov kev txo qis ntau dua ntawm lub teeb txwv lawv siv rau ntau qhov sib txuas luv dua hauv cov tsev lossistsheb.

Optical telecommunication feem ntau yog ua nroginfraredLub teeb nyob rau hauv lub wavelength ranges ntawm 0.8-0.9 μm los yog 1.3-1.6 μm - wavelengths uas muaj txiaj ntsig tsim los ntawmteeb-emitting diodeslos yogsemiconductor lasersthiab qhov ntawd raug kev txom nyem tsawg kawg nkaus hauv cov iav fibers.Fiberscope soj ntsuam hauv endoscopy los yog kev lag luam yog ua nyob rau hauv lub pom wavelengths, ib pob ntawm fibers siv rauteeb pom kevthaj chaw kuaj nrog lub teeb thiab lwm lub pob ua haujlwm raws li elongatedlensrau xa cov duab mus rau lubtib neeg qhov muaglos yog lub koob yees duab yees duab.

Fiber optic receivers hloov lub teeb teeb liab mus rau hauv hluav taws xob teeb liab siv los ntawm cov khoom siv xws li computer networks.Cov khoom siv hluav taws xob-kho qhov muag no muaj cov khoom siv kho qhov muag, lub suab nrov qis, thiab cov teeb liab txias circuitry.Tom qab lub optical detector converts cov khoom kho qhov muag teeb liab mus rau hauv ib tug hluav taws xob teeb liab, lub amplifier nce nws mus rau ib theem uas haum rau ntxiv teeb liab ua.Hom kev hloov pauv thiab cov khoom siv hluav taws xob yuav tsum txiav txim siab seb yuav tsum muaj lwm yam circuitry.

Fiber optic receivers siv qhov zoo-tsis zoo junctions (PN), zoo-intrinsic negative (PIN) photodiodes, los yog avalanche photodiodes (APD) ua optical detectors.Lub teeb liab xa tuaj yog xa los ntawm fiber ntau optic transmitter (lossis transceiver) thiab taug kev raws ib hom lossis ntau hom kab hluav taws xob, nyob ntawm qhov muaj peev xwm ntawm cov cuab yeej.Cov ntaub ntawv demodulator hloov lub teeb liab rov qab rau hauv nws daim ntawv hluav taws xob qub.Nyob rau hauv ntau txoj kev fiber ntau optic systems, wavelength division multiplexing (WDM) Cheebtsam kuj siv.

Semiconductors thiab Photodiodes

Engineering360 SpecSearch database tso cai rau cov neeg siv khoom lag luam xaiv cov khoom los ntawm hom semiconductor thiab hom photodiode.Ob hom semiconductors yog siv nyob rau hauv fiber ntau optic receivers.

Silicon semiconductors yog siv nyob rau hauv luv- wavelength receivers nrog ib tug ntau ntawm 400 nm mus rau 1100 nm.

Indium gallium arsenide semiconductors yog siv nyob rau hauv ntev wavelength receivers nrog ib tug ntau ntawm 900 nm mus rau 1700 nm.

Raws li tau piav saum toj no, fiber ntau optic receivers siv peb hom photodiodes.

PN junctions yog tsim nyob rau hauv ciam teb ntawm ib tug P-hom thiab N-hom semiconductor, feem ntau nyob rau hauv ib tug siv lead ua ntawm doping.

PIN photodiodes muaj thaj tsam loj, nruab nrab-doped intrinsic sandwiched ntawm P-doped thiab N-doped semiconducting cheeb tsam.

APDs yog tshwj xeeb PIN photodiodes uas khiav lag luam nrog siab rov qab tsis zoo voltages.

Amplifiers thiab Connectors

Fiber optic receivers siv ob qho tib si low-impedance lossis transimpedance amplifiers.

Nrog cov khoom siv qis impedance, bandwidth thiab receiver suab nrov txo nrog kev ua haujlwm.

Nrog cov khoom siv trans-impedance, bandwidth ntawm lub receiver cuam tshuam los ntawm qhov nce ntawm lub amplifier.

Feem ntau, fiber ntau optic receivers muaj xws li tshem tau adapter rau kev sib txuas rau lwm yam khoom siv.Cov kev xaiv muaj xws li D4, MTP, MT-RJ, MU, thiab SC

Txais Kev Ua Haujlwm

Thaum siv Engineering360 rau cov khoom lag luam, cov neeg yuav khoom yuav tsum qhia cov kev txwv no rau kev ua haujlwm ntawm fiber ntau optic.

Cov ntaub ntawv tus nqi yog tus naj npawb ntawm cov khoom xa mus rau ib ob, thiab yog ib qho kev qhia ceev.

Lub sij hawm txais tos kuj yog ib qho kev qhia ntawm kev ceev, tab sis qhia txog lub sij hawm xav tau rau lub teeb liab hloov los ntawm qhov teev 10% mus rau 90% lub zog.

rhiab heev qhia qhov tsis muaj zog optical teeb liab uas lub cuab yeej tau txais.

Dynamic ntau yam muaj feem xyuam rau rhiab heev, tab sis qhia txog lub hwj chim ntau yam uas lub cuab yeej ua haujlwm.

Teb yog qhov piv ntawm radiant zog nyob rau hauv watts (W) mus rau lub resulting photocurrent nyob rau hauv amperes (A).
