Taw qhia rau ib hom optical fiber ntau
Tso lus
Kev piav qhia ntawm "Ib hom fiber ntau" hauv cov ntaub ntawv kawm: Feem ntau, thaum v tsawg dua 2.405, tsuas yog ib lub ncov dhau los ntawm fiber ntau, yog li nws hu ua ib hom fiber ntau. Nws cov tub ntxhais yog nyias nyias, txog 8-10 microns, thiab cov qauv dispersion tsawg heev. Lub ntsiab tseem ceeb cuam tshuam rau bandwidth ntawm fiber ntau kis tau tus mob yog ntau hom dispersion, thiab hom dispersion yog qhov tseem ceeb tshaj plaws. Ib hom fiber ntau muaj qhov sib txawv tsawg, yog li nws tuaj yeem xa lub teeb hla lub dav zaus thiab qhov ntev.
Tib hom optical fibers muaj ib txoj kab uas hla ntawm 10 microns, uas tso cai rau kev sib kis ntawm ib hom teeb pom kev zoo thiab tshem tawm cov kev txwv ntawm bandwidth thiab modal dispersion. Txawm li cas los xij, vim lub me me txoj kab uas hla ntawm ib hom kho qhov muag fibers, nws yog ib qho nyuaj rau tswj cov kis ntawm lub teeb beams, yuav tsum tau kim heev lasers raws li lub teeb lub cev. Lub ntsiab kev txwv ntawm ib hom optical cables yog cov khoom dispersion. Tib hom optical cables feem ntau siv lasers kom tau txais bandwidth siab, thiab txij li cov LEDs tso tawm ntau lub teeb pom kev zoo nrog cov bandwidth sib txawv, cov khoom siv dispersion yog qhov tseem ceeb heev.
Los ntawm tus nqi saib, vim yog tus nqi siab ntawm optical transceivers, tus nqi ntawm kev siv ib hom fiber ntau optic cables yuav siab dua li ntawm ntau hom fiber ntau optic cables.
Ib hom Fiber (SMF)
Piv nrog rau multimode fiber ntau, ib hom fiber ntau muaj ib txoj kab uas hla ntau dua, tsuas yog 8-10 μ m. Vim tsuas yog kis tau ib hom, tsis muaj hom rau hom dispersion, tsawg tag nrho dispersion, thiab dav bandwidth. Tib hom fiber ntau yog siv nyob rau hauv lub wavelength ntawm 1.3-1.6 μ m. Los ntawm kev tsim cov khoom siv refractive index faib ntawm cov fiber ntau thiab xaiv cov khoom siv purity los npaj cov cladding uas yog 7 npaug loj dua cov tub ntxhais, qhov poob qis tshaj plaws thiab qhov tsawg kawg nkaus dispersion tuaj yeem ua tiav ib txhij nyob rau hauv no wavelength ntau.
Tib hom fiber ntau yog siv nyob rau hauv ntev-ntev, muaj peev xwm fiber ntau optic kev sib txuas lus systems, fiber optic hauv cheeb tsam network, thiab ntau yam fiber ntau optic sensors.
