Kev Rho Tawm Hauv Kho Qhov Muag Fiber
Chromatic dispersion, d, nyob rau hauv ib qho kev fiber ntau tshwm sim thaum pab pawg tshaj tawm thiab theem velocity ntawm lub ntsuas kho kho qhov muag / zaus. Nws yog feem ntau yog cov lej ntawm ob qho tib si, cov khoom tawg thiab waveGuide discersion:
Cov khoom xa tawm los ntawm kev hloov pauv ntawm cov khoom siv kom tsis txhob muaj wavelength, uas hloov pauv cov lus tshaj tawm ntawm lub teeb ua kev ua haujlwm ntawm yoj. WaveGuide dispersion yog cais cov nyhuv, tshwm sim los ntawm geometry ntawm fiber ntau WaveGuide. WaveGuide cov khoom kuj tseem muaj nuj nqi ntawm nthwv dej wavelength; Thiaj li, hloov lub wavelength cuam tshuam li cas lub teeb yog coj nyob rau hauv ib qho {{2} hom fiber ntau. Piv txwv li, txo qis nthwv dej yuav nce cov kev txheeb ze plugawide qhov ntev, ua rau muaj kev hloov pauv ntawm lub teeb rau hauv cladding thiab core.
Lwm pab ntsuas hluav taws xob yog qhov dispersion coefficient ,, uas tseem hu ua theem tsis tu ncua lossis hom}}}-}}} {}}}} {}}}} - Yog tias lub mem tes optical tau txais kev sib tw nrog cov roj fiber ntau, l, tom qab ntawd cov theem hloov sib txuam ua haujlwm txhais tau tias:
tuaj yeem nthuav dav kom suav nrog cov qib siab dua- kev txiav txim tsis yog cov qauv tsis sib xws,iCov. Tshwj xeeb, thib ob - kev txiav txim thiab thib peb-}} kev txiav txim siab tshaj tawm muaj feem cuam tshuam los ntawm:
Nyob qhov twg DDtxoj plaub/ DT yog lub npe hu ua kev tshaj tawm kev swb, uas tuaj yeem yog qhov zoo, tsis zoo, lossis sau ntawv, thiab sau ua:
Pab pawg tshaj tawm kev faib tawm (GVD) yog cov tawv nqaij rau sab nrauv vim muaj kev sib txawv ntawm cov picoseconds ntawm cov picoseconds lossis luv. Cov pab pawg tshaj tawm, vg, tuaj yeem txhais tau tias yog tus nqi ntawm qhov uas tag nrho cov hnab ntawv txhua tus yuav tsum hais tawm:
Uas tso cai rau cov pab pawg tshaj tawm kom raug txhais raws li:
Tsis muaj kev hloov pauv ntawm cov duab ntawm cov mem tes ntawm lub cev thaum GVD sib npaug xoom, txawm li cas los xij yuav muaj ib txwm nthuav dav thaum GVD yog Nonzero. Thaum tus GVD yog ntau dua xoom, lub suab ntev ntev yuav protainate nrawm dua li wavelengths luv dua; Thiab thaum GVD yog tsawg dua xoom, lub suab ntev ntev yuav profagate qeeb dua.
Polarization - hom kev faib tawm (PMD) hauv cov fiber ntau tshwm sim los ntawm cov fiber ntau hauv fiber ntau ntxhov siab thiab geometry. Nyob rau hauv lub zaus sau, nws pib nws tus kheej yog txoj kab kev hloov pauv hauv cov tswv yim ruaj khov nrog ua kom muaj zaus. Nyob rau hauv lub sijhawm sau, nws pib nws tus kheej raws li lub sijhawm ncua sij hawm ncua ntawm cov mem tes hais txog cov fiber ntau. Cov pab pawg qeeb yog qhov sib txawv ntawm qhov txhais tau tias lub sijhawm tuaj txog ntawm cov tswv yim fiber ntau thiab cov tso zis fiber ntau.
Polarization - Lub Xeev Pairs (PSP) yog hom huab cua ntawm polarization hais ntawm lub xeev kho cov fiber ntau. Txog kev sib tw polience {{2} Taug kev los ua cov kab, cov no yog cov aav fiber ntau thiab feem ntau yog ib theem hloov pauv thiab pab pawg sib txawv. Cov pab pawg sib txawv qeeb (DGD) yog qhov sib txawv hauv pab pawg ncua ntawm Orthoogonal khub ntawm polarization cov xeev. DGD nce kev sib sau ua ke rau lub hauv paus xwm fab ntawm cov fiber ntau. Polarization {{6 {6 hom kev tawg tuaj yeem txhais tau tias yog qhov sib npaug ntawm DGD thiab cov ntsiab lus hauv kev ua kom qeeb axis.
Dispersion -} nyiaj them fiber ntau
Txij li thaum dispersion yog inevable hauv optical fibers, dispersion -}} Kev them nyiaj rau hauv cov tshuab kho qhov muag. Tag nrho kev faib tawm ntawm cov fibers yog rov qab nyob rau hauv signitude thiab ntau dua lawv tuaj yeem siv rau qhov sib npaug ntawm ib qho qauv ntawm ib qho kev sib txawv lossis kev sib tw {}} tswj cov fiber ntau. Txoj kab kev tsis zoo ntawm kev ua kom zoo ua rau kev tshem tawm cov wavelength loj dua, vim tias cov dispersion nqes ntawm cov qauv roj muaj feem ntau zoo. Feem ntau, luv ntev ntawm DCF tau raug txi mus rau hauv ntev ntev ntawm cov qauv fiber kom them nyiaj rau kev dispersion, raws li qhia hauv daim duab.
Them Nyiaj Them Nyiaj Schnology
Lub dispersion - nyiaj fiber ntau yuav tsum tau xaiv kom phim cov dispersion ntawm ib txwm sm lossis tsaus ntuj nti tawm ntawm cov kev saib xyuas lub optical. Qhov no txhais tau tias DCF yuav tsum sib phim tsis tsuas yog kev dispersion, d, tab sis cov dispersion nqes, ddtxoj plaub/ DOM. Qhov sib piv ntawm ob yam no yog hu ua cov txheeb ze rho tawm nqes hav. Ib yam li ntawd, tus piv2/ 3Yuav siv tau los ua lwm tus lej ntsuas kom pom kev xaiv fiber ntau. Qhov ntau zoo ib yam li cov tsis sib xws yog rau DCF thiab cov qauv fiber ntau, qhov tsawg dua distorted thiab tsis muaj kev sib kis optical pulse yuav yog cov khoom tawm.
Txhawm rau txiav txim siab qhov ntev ntev rau DCF siv cov kev sib txuam no, ib qho tuaj yeem daws cov kev sib txuam hauv qab no siv cov kev faib tawm hauv qab no ntawm cov wavelength:
