Thaum tshawb hauv Is Taws Nem rau network fiber ntau thaj cables, Peb yuav tsum txiav txim siab 2 yam tseem ceeb: qhov kis tau tus mob nyob deb thiab qhov project nyiaj pab.Yog li kuv puas paub qhov twg fiber optic cable kuv xav tau?
Dab tsi yog ib hom fiber ntau cable?
Tib hom (SM) fiber ntau cable yog qhov kev xaiv zoo tshaj plaws rau kev xa cov ntaub ntawv mus ntev.Lawv feem ntau yog siv rau kev sib txuas ntawm thaj chaw loj, xws li cov tsev kawm qib siab hauv tsev kawm qib siab thiab cable TV network.Lawv muaj bandwidth siab dua li multimode cables xa mus txog ob zaug ntawm kev xa tawm.Feem ntau singlemode cabling yog xim-coded daj.
Singlemode cables muaj cov tub ntxhais ntawm 8 mus rau 10 microns.Hauv ib hom kab hluav taws xob, lub teeb mus rau qhov chaw ntawm cov tub ntxhais hauv ib lub wavelength.Qhov tsom teeb ntawm lub teeb no tso cai rau lub teeb liab mus nrawm dua thiab ntev dua yam tsis muaj kev poob ntawm cov teeb liab zoo tshaj qhov ua tau nrog multimode cabling.
Multimode fier cable yog dab tsi?
Ntau hom (MM) fiber ntau cable yog qhov kev xaiv zoo rau kev xa cov ntaub ntawv thiab lub suab teeb liab hla luv luv.Lawv feem ntau yog siv rau cov ntaub ntawv thiab kev siv suab / kev pom nyob rau hauv cov cheeb tsam hauv cheeb tsam thiab kev sib txuas hauv cov tsev.Multimode cables feem ntau yog xim-coded txiv kab ntxwv lossis aqua.
Multimode cables muaj cov tub ntxhais ntawm 50 lossis 62.5 microns.Nyob rau hauv multimode cables, cov tub ntxhais loj sib sau ua ke ntau lub teeb piv rau singlemode, thiab lub teeb no qhia tawm ntawm cov tub ntxhais thiab tso cai rau cov teeb liab ntau dua.Txawm hais tias muaj txiaj ntsig zoo dua li singlemode, multimode cabling tsis tuav cov teeb liab zoo nyob rau qhov ntev.
Nws tseem yog ib qho tseem ceeb uas yuav tau xav txog hom kev thov thaum txiav txim siab seb puas yuav siv ib hom lossis multimode fiber ntau.Piv txwv li, dhau qhov kev ncua deb, multimode ua haujlwm zoo rau CCTV tab sis tsis muaj kev sib kis ceev.
Qhov tseem ceeb tshaj plaws yog qhov sib txawv tseem ceeb ntawm singlemode thiab multimode fiber optic cables, Vam tias nws yuav pab koj xaiv txoj cai ntawm kev yuav khoom fiber ntau cables.
