Tib hom fibersmuab ib txoj hauv kev rau lub teeb rau kev mus los thiab tau txhais los ntawm lawv cov tub ntxhais me me ntawm kwv yees li 8.3 µm.Multimode fibers, ntawm qhov tod tes, muaj ntau txoj hauv kev, lossis hom, uas lub teeb tuaj yeem taug kev los ntawm fiber ntau optical. Cov tub ntxhais loj no loj dua, xws li 50 µm txog 62.5 µm. Qhov blog no qhia txog qhov sib txawv tseem ceeb ntawm ob hom fiber ntau no, tshawb nrhiav lawv cov kev tsim kho, kev siv, cov yam ntxwv ntawm kev nthuav tawm lub teeb, thiab cov txheej txheem xaiv.
Qhov txawv ntawm Kev Tsim Kho
Core Diameter Variations
Qhov pom tseeb tshaj qhov sib txawv ntawm multimode thiab ib hom fibers nyob rau hauv lawv cov core diameters. Multimode fibers feem ntau muaj cov tub ntxhais loj diameters, xws li 50 txog 62.5 micrometers. Nyob rau hauv sib piv, ib hom fibers feature ntau me me diameters, feem ntau nyob ib ncig ntawm 8 mus rau 10 micrometers. Qhov sib txawv tseem ceeb ntawm cov tub ntxhais loj no cuam tshuam ncaj qha rau txoj kev lub teeb mus los ntawm txhua hom fiber ntau.
Refractive Index Profiles
Multimode fibers feem ntau siv cov qhab-nees-index profile, qhov twg cov refractive index maj mam txo los ntawm qhov nruab nrab ntawm cov tub ntxhais mus rau nws sab ntug. Qhov kev tsim no pab txo qis modal dispersion thiab txhim kho bandwidth peev xwm. Ib hom fibers, ntawm qhov tod tes, siv cov kauj ruam-index profile nrog ib qho kev ntsuas tsis sib xws thoob plaws hauv lub hauv paus. Qhov kev teeb tsa no tso cai rau kev nthuav tawm tsuas yog ib hom ntawm lub teeb, li no lub npe "ib hom."
Cladding yam ntxwv
Thaum ob hom fiber ntau feature cladding kom muaj lub teeb nyob rau hauv lub hauv paus, lub cladding-rau-core piv txawv.Multimode fibersfeem ntau muaj cladding txoj kab uas hla ntawm 125 micrometers, uas ua rau ib tug me me cladding-rau-core piv piv rau ib hom fibers. Tib hom fibers tuav tib yam 125-micrometer cladding txoj kab uas hla tab sis nrog ib tug ntau me me tub ntxhais, ua rau ib tug loj cladding-rau-core piv.
Qhov sib txawv hauv Daim Ntawv Thov
Short-Distance vs. Long-Distance Communication
Multimode fibers ua tau zoo nyob rau hauv daim ntawv thov luv luv, feem ntau nyob rau hauv cov tsev lossis ib puag ncig hauv tsev kawm ntawv. Lawv feem ntau siv rau kev ncua deb txog 300 meters, ua rau lawv zoo tagnrho rau cov chaw hauv cheeb tsam (LANs) thiab cov chaw zov me nyuam. Ib hom fibers, nrog rau lawv cov peev xwm nyob deb, yog qhov kev xaiv zoo tshaj plaws rau kev sib txuas lus sib txuas lus hla ntau pua lossis ntau txhiab mais.
Kev txiav txim siab Bandwidth
Lub peev xwm bandwidth ntawm multimode fibers feem ntau qis dua li ntawm ib hom fibers. Qhov kev txwv no ua rau ntau hom fiber ntau haum rau cov ntawv thov nrog cov kev xav tau nruab nrab bandwidth, xws li kev lag luam tes hauj lwm thiab qee qhov chaw lag luam. Tib hom fibers, khav theeb ntau dua bandwidth peev xwm, yog qhov tseem ceeb rau kev kub ceev, cov ntaub ntawv nyob deb xa mus rau hauv kev sib txuas lus thiab cable TV network.
Nqi thiab Installation Factors
Multimode fibers feem ntau nthuav tawm cov tshuaj siv nyiaj ntau dua rau cov ntawv thov luv luv. Cov tub ntxhais txoj kab uas hla loj dua tso cai rau kev siv cov khoom siv hluav taws xob tsawg dua thiab cov khoom sib txuas, txo cov nqi tag nrho.Tib hom fibers, thaum kim dua nyob rau hauv cov nqe lus ntawm cov khoom siv thawj zaug, muab cov txiaj ntsig zoo rau cov kev siv mus sij hawm ntev vim lawv qhov kev ua tau zoo dua thiab cov teeb liab poob qis dua qhov kev ncua deb.
Qhov sib txawv ntawm Lub Teeb Tshaj Tawm
Modal Dispersion yam ntxwv
Multimode fibers tso cai rau ntau hom teeb kom nthuav tawm ib txhij los ntawm cov tub ntxhais. Qhov tshwm sim no, hu ua modal dispersion, tuaj yeem ua rau lub teeb liab degradation ntev dua li cov teeb pom kev sib txawv ntawm qhov sib txawv me ntsis. Ib hom fibers tshem tawm modal dispersion los ntawm kev txhawb nqa tsuas yog ib hom ntawm lub teeb propagation, uas ua rau kom pom tseeb dua cov kev ncua deb.
Kev txiav txim siab wavelength
Multimode fibers feem ntau ua haujlwm ntawm luv wavelengths, feem ntau yog 850nm lossis 1300nm. Cov wavelengths no zoo haum rau cov tub ntxhais diameters loj dua thiab luv dua kis tau tus mob cuam tshuam nrog kev siv multimode. Ib hom fibers, tsim los rau kev sib kis mus ntev, ua haujlwm ntawm lub wavelengths ntev, feem ntau 1310 nm lossis 1550 nm. Cov wavelengths ntev dua no muaj kev cuam tshuam tsawg dua, tso cai rau cov teeb liab mus ntxiv yam tsis muaj degradation.
Chromatic Dispersion Effects
Ob hom fiber ntau muaj chromatic dispersion, qhov sib txawv wavelengths ntawm lub teeb mus ncig ntawm qhov sib txawv me ntsis. Txawm li cas los xij, qhov cuam tshuam ntawm chromatic dispersion tau tshaj tawm nyob rau hauv ib hom fibers vim lawv qhov sib kis ntev dua. Advanced ib hom fiber ntau tsim, xws li dispersion-hloov fibers, pab txo cov teebmeem no nyob rau hauv daim ntawv thov ntev.
Yuav Ua Li Cas Xaiv Ntawm Ib Hom thiab Multimode?
Yam yuav tsum tau muaj nyob deb
Lub hauv paus tseem ceeb hauv kev xaiv ntawm ib hom thiab multimode fibers yog qhov yuav tsum tau sib kis deb. Rau cov ntawv thov luv luv hauv qab 300 meters,multimode fibersfeem ntau muab cov nqi tsim nyog. Thaum qhov kev ncua deb tshaj 300 meters los yog rau yav tom ntej-proofing networks, ib hom fibers yog qhov kev xaiv zoo tshaj vim lawv cov kev ua tau zoo nyob deb.
Bandwidth Xav Tau
Kev ntsuam xyuas cov kev xav tau bandwidth tam sim no thiab yav tom ntej yog qhov tseem ceeb hauv kev xaiv fiber ntau. Multimode fibers tuaj yeem txhawb nqa bandwidths txog 100 Gbps nyob rau qhov luv luv, ua rau lawv haum rau ntau daim ntawv thov kev lag luam. Txawm li cas los xij, rau qhov siab-bandwidth, kev xav tau ntev-ntev lossis kom haum rau yav tom ntej network nthuav dav, ib hom fibers muaj qhov tsis sib xws thiab kev ua tau zoo.
Kev txiav txim siab nqi
Thaum ib hom fibers muaj kev ua tau zoo dua, lawv feem ntau tuaj nrog cov nqi pib dua vim tias kim dua transceivers thiab connectors. Multimode fibers tuaj yeem siv nyiaj ntau dua rau kev siv luv luv, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem uas twb muaj lawm. Nws yog ib qho tseem ceeb uas yuav tau xav txog cov nqi tam sim ntawd thiab mus sij hawm ntev thaum txiav txim siab.
Compatibility nrog Existing Infrastructure
Thaum txhim kho lossis nthuav cov tes hauj lwm, kev sib raug zoo nrog cov txheej txheem uas twb muaj lawm yog qhov tseem ceeb rau kev txiav txim siab. Multimode fibers tej zaum yuav yog qhov kev xaiv muaj txiaj ntsig yog tias lub network tam sim no feem ntau siv tshuab multimode. Txawm li cas los xij, yog tias lub sijhawm ntev scalability yog qhov tseem ceeb, kev hloov mus rau ib hom fiber ntau yuav tau txais txiaj ntsig ntau dua txawm tias muaj peev xwm ua rau lub sijhawm luv luv.
Environmental Factors
Kev ua haujlwm ib puag ncig tuaj yeem cuam tshuam kev xaiv fiber ntau. Tib hom fibers feem ntau muaj zog dua rau lwm yam xws li kub hloov pauv thiab kev ntxhov siab ntawm lub cev, ua rau lawv zoo tagnrho rau kev lag luam sab nraum zoov thiab hnyav. Multimode fibers, thaum tsim nyog rau kev tswj hwm sab hauv tsev, yuav xav tau kev tiv thaiv ntxiv hauv qhov xav tau ntau dua.
Kev txiav txim siab yav tom ntej
Raws li cov ntaub ntawv xav tau txuas ntxiv zuj zus, yav tom ntej-proofing network infrastructure ua qhov tseem ceeb zuj zus.Tib hom fibersmuab lub peev xwm ntau dua rau kev hloov kho tshiab thiab kev nthuav dav bandwidth yam tsis tas yuav hloov fiber ntau. Qhov kev xav mus sij hawm ntev no tuaj yeem cuam tshuam cov nqi pib ntau dua thiab muab kev daws teeb meem txuas ntxiv txuas ntxiv.
