Vim li cas nws tseem ceeb

Teeb Liab Zoo

Thaum koj xa cov ntaub ntawv ntawm kev kub ceev los ntawm kev siv kho qhov muag siv kho tshiab, teeb liab zoo ua qhov tseem ceeb tshaj plaws. Chromatic dispersion ua rau lub teeb pulses kom kis tawm thaum lawv mus ncig. Qhov kev nthuav dav no ua rau muaj kev sib tshooj thiab ua rau nws nyuaj rau koj cov khoom siv kom paub qhov txawv ntawm cov ntaub ntawv ntawm tus kheej. Koj pom cov kev cuam tshuam hnyav tshaj plaws thaum koj lub network ua haujlwm saum toj kawg 10 GBPS. Ntawm cov nrawm nrawm, txawm tias me me ntawm kev tshem tawm tuaj yeem txwv tsis pub muaj kev ncaj ncees.

Chromatic dispersion los ntawm ob qho khoom siv thiab cov ntaub qhwv cov teebmeem. Cov khoom siv dispersion tshwm sim vim tias txawv wavelengths taug kev ntawm qhov sib txawv. WaveGuide discersion los ntawm cov qauv fiber ntau, qhov twg cov tub ntxhais thiab cladding muaj cov khoom lag luam txawv.

Raws li qhov tshwm sim, lub teeb liab uas koj tau txais thaum kawg ntawm cov fiber ntau yuav saib txawv heev ntawm qhov koj xa. Qhov distortion lowers lub teeb liab - rau - suab sib piv thiab nce lub caij nyoog ntawm cov yuam kev.

Cov lus qhia: Yog tias koj pom qhov yuam kev tsawg dua lossis cov teeb liab tsis zoo hauv koj lub siab ceev, cov chromatic dispersion tuaj yeem yog qhov ua rau.

Cov Nqi

Koj lub peev xwm los thawb cov ntaub ntawv siab dua nyob ntawm seb koj lub network cuam li cas rau koj lub network. Raws li koj nce qhov nrawm, cov pulses nqa koj cov ntaub ntawv ua luv dua thiab ze dua ua ke. Kev Rho Tawm Rho Tawm Stramines cov pulses, ua rau lawv hla dhau. Qhov kev sib tshooj sib tshooj no ua rau inters-} cim kev cuam tshuam, uas txwv cov ntaub ntawv ntau tshaj plaws koj lub cev tuaj yeem pab txhawb nqa tau.

Hauv kev sib koom tes thiab kev lag luam ib puag ncig, cov neeg tsim qauv feem ntau siv cov nyiaj them poob haujlwm feem ntau siv fiber ntau (DCF) hauv series nrog ib qho {} hom fiber. Qhov kev sib ze no pab ua cov kev tawg ua kom muaj kev tshem tawm, tshwj xeeb yog ib ncig ntawm 1550 nm wavelength, thiab tso cai rau koj kom txuas ntxiv relay deb thiab txo cov paib poob.

Thaum npaj cov kev hloov pauv mus rau 40 GB / s lossis siab dua, koj yuav tsum tau nyiaj rau kev tawm tsam cuam tshuam. Tsis quav ntsej lawv tuaj yeem ua rau muaj kev ua tsis tau zoo thiab kev nqis peev ntau.

Kev Ntseeg Network

Network kev ntseeg tau muaj peev xwm thaum chromatic disgersion stretes lossis flattens lub pulses binary uas sawv cev rau koj cov ntaub ntawv. Tshaj dhau mus deb, nws yuav nyuaj los paub qhov txawv ntawm cov thiab zeros. Qhov kev tsis meej pem ua rau muaj kev yuam kev siab dua thiab txo cov ntaub ntawv muaj peev xwm ntawm koj cov fiber.

Nyob rau hauv ntev -} haul networks, chromatic dispersion yog qhov kev txhawj xeeb loj. Qhov kis tau ntawm - tawm lub teeb pulses tuaj yeem txo cov bandwidth thiab kev ntseeg tau ntawm koj lub cev.

Enterprise Networks tseem tau cov nyom ntawm lawv nplai. Yog tias koj tsis tswj kev tawg, koj lub network yuav muaj kev tawm tsam lossis yuav tsum tau saib xyuas ntau zaus.

Nco tseg: Ntau lub tshuab xov tooj siv tau tshaj lij cov tswv yim txhim kho tshuab txhim kho kom muaj kev ua tau zoo thiab kev ntseeg tau kom nrawm dua thiab ua kom ntev dua.

Chromatic dispersion piav qhia

Chromatic dispersion txhais

Koj tau ntsib cov kev faib tawm chromatic thaum txawv wavelengths ntawm lub teeb kev taug kev ntawm kev ceev ntawm kev siv fiber ntau. Qhov tshwm sim no ua rau kev sib cais ntawm lub teeb rau hauv nws cov xim. Hauv kev sib txuas lus kho qhov muag fiber ntau, chromatic dispersion ncaj qha cuam tshuam qhov koj xa cov ntaub ntawv. Nws txiav txim siab qhov siab tshaj plaws nyob deb ntawm cov rov ua dua tshiab thiab cuam tshuam cov ntaub ntawv {{} nqa muaj peev xwm ntawm ib qho {} hom hom fibers. Thaum koj xa cov mem tes ntawm lub teeb, txhua qhov kev sib tw sib txawv txav ntawm qhov nrawm me ntsis, yog li cov mem tes kis tawm thaum nws mus rau hauv cov fiber ntau.

Chromatic dispersion yog ib qho tseem ceeb uas txwv kev ua tau zoo ntawm high - ceev kho qhov muag. Yog tias koj xav tswj kev piav txog kev pom meej thiab tsis meej, koj yuav tsum nkag siab li cas cov nyhuv no.

Chromatic dispersion hom

Chromatic dispersion hauv kho qhov muag cov fibers los ntawm ob qhov chaw loj. Txhua hom muaj lub cev txawv ntawm lub cev thiab cuam tshuam rau koj lub network hauv txoj kev tshwj xeeb.

Khoom Siv Hluav Taws Xob

Cov khoom siv dispersion tshwm sim vim hais tias cov ntsuas hluav taws xob kom sov ntawm cov iav hloov nrog wavelength. Thaum koj xa ib lub hnab looj tes muaj ntau lub wavelengths, txhua tus mus ncig ntawm kev ceev los ntawm cov fiber ntau.

Cov iav khoom nws tus kheej ua rau cov nyhuv no. Piv txwv li, silica - Cov ntaub ntawv fiber ntau-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} depend depend depend depend of of depend depend depend depend of of of of refr depend of of of refr refr refr of on refr refr refr່ານ refr refr່ານ cov hluav taws xob kom ua. Qhov no txhais tau tias lub teeb xiav thiab lub teeb liab yuav tsis tuaj txog tib lub sijhawm, txawm tias koj tso lawv ua ke.

WaveGuide Dispersion

WaveGuide dispersion tshwm sim los ntawm cov qauv ntawm cov fiber. Cov tub ntxhais thiab cladding muaj cov kev ua kom txawv txav, thiab txoj kev pom kev zoo nyob rau hauv qhov tseem ceeb hloov nrog nthwv dej.

Raws li koj siv wavelengths txawv, kev faib tawm ntawm lub teeb hluav taws xob nruab nrab ntawm cov tub ntxhais thiab cladink hloov. Cov kev hloov pauv no tau zoo ntawm txhua lub nthwv dej, ntxiv lwm txheej ntawm dispersion dhau cov khoom nws tus kheej.

Chromatic dispersion mem tes nthuav dav

Thaum koj kis cov mem tes luv luv ntawm lub teeb, chromatic dispersion ua rau nws kis tawm thaum nws txav mus los ntawm cov fiber. Tus txheej txheem no hu ua mem tes dav. Koj yuav pom tias cov mem tes poob nws lub ntsej muag ntse thiab ua rau nws dav, ua rau nws nyuaj rau kev paub qhov txawv ntawm tus txais.

Raws li cov mem tes taug kev, cov zaus ntau zaus txav ntawm cov sib txawv. Qhov no nthuav tawm txo lub zog lub zog ntawm mem tes.

Lub liner qhov chaw koj siv emits muaj ntau yam ntawm ntau zaus. Yog tias koj qhov chaw muaj qhov dav dav dav, cov mem tes yuav muaj ntau qhov chaw nquag muaj dua tshiab, uas ua rau nrawm dua thiab nthuav dav ntxiv.

• Mem tes ntsuas kev txwv cov ntaub ntawv siab tshaj plaws thiab kis tau deb koj tuaj yeem ua tiav yam tsis muaj qhov yuam kev.
• Txhawm rau kom nkag siab yog vim li cas qhov no tshwm sim, koj yuav tsum tau saib ob lub tswv yim tseem ceeb: Theem Tshawb Fawb thiab Cov Phauj Kawm Ntawv.
• Theem Velocity yog qhov nrawm ntawm uas ib theem tsis tu ncua ntawm nthwv dej txav los ntawm cov fiber.
• Pab pawg tshaj tawm yog qhov nrawm ntawm uas lub zog tag nrho thiab cov ntaub ntawv nyob hauv cov mem tes taug kev.

Kev tawm tsam chromatic tshwm sim vim muaj ntau zaus zaus muaj cov theem sib txawv thiab pab pawg sib txawv. Qhov sib txawv no ua rau cov mem tes kom dav thaum nws nthuav tawm.

Pab pawg - qhov kev faib tawm nyob ntawm seb qhov ntsuas muaj fiber ntau nrog nthwv cua nrog wavelength.

Cov lus qhia: Yog tias koj xav ua kom zoo rau koj lub network rau high- cov ntaub ntawv ceev, koj yuav tsum ntsuas thiab tswj ob hom chromatic dispersion. Qhov no ua kom koj cov pulses nyob twj ywm thiab koj cov ntaub ntawv tuaj txog hauv zog.

Cuam tshuam ntawm kev ua tau zoo

Kev Sib Kis

Koj xav tau koj cov kev sib txuas kho qhov muag fiber ntau kom ncav cuag kom deb li deb tau yam tsis poob cov ntaub ntawv zoo. Chromatic dispersion txwv qhov kev ncua deb ntawm kev ua rau lub teeb liab tawm mus thaum lawv mus ncig. Cov nyhuv no yuav dhau los ua kom pom tau ntau dua cov ntaub ntawv siab dua cov ntaub ntawv. Raws li cov qog dav dav, lawv pib sib tshooj, ua rau nws nyuaj rau koj tus txais yuav qhia qhov twg ib qho xaus thiab pib tom ntej.

• Cov peev txheej hauv koj lub network tsis zoo nkauj monochromatic. Lawv tawm thaj tsam ntawm nthwv wavelengths.
• Txhua lub moos wavelengted ntawm kev ceev sib txawv los ntawm cov fiber ntau, yog li tus mem tes kis tawm deb.
• Ntawm kev nrawm dua, cov kis las no nce ntxiv, uas sheeth qhov siab tshaj plaws nyob nrug koj lub teeb liab tuaj yeem taug kev ua ntej nws dhau los ua ntej.

Koj tuaj yeem pom qhov cuam tshuam hauv cov lus hauv qab no:

Raws li koj nce cov ntaub ntawv cov nqi, chromatic dispersion txo qhov kev sib kis tau ntev tshaj plaws. Koj yuav tsum siv cov tswv yim them nyiaj los tswj kom muaj ntev-} haul kev ua haujlwm.
