Cov hom dispersion me me heev, uas tsim nyog rau kev sib txuas lus ntev, tab sis kuj tseem muaj cov khoom tawg thiab cov khoom siv waveguide dispersion, yog li ib hom fiber ntau muaj qhov yuav tsum muaj ntau dua rau qhov dav dav thiab kev ruaj ntseg ntawm cov teeb ci, uas yog, spectral dav yuav tsum nqaim thiab qhov chaw ruaj khov yuav tsum yog qhov zoo.
Yam ntxwv
Ib hom fiber ntau muaj cov tub ntxhais txoj kab uas hla ntawm 10micron, tuaj yeem ua kom kis tau ntawm tib hom teeb pom kev, thiab tuaj yeem txo qhov kev txwv ntawm qhov tsawg zaus thiab hom kev tawg. Txawm li cas los xij, vim hais tias cov tub ntxhais txoj kab uas hla ntawm ib hom fiber ntau kuj tsawg, nws nyuaj rau kev tswj hwm kev sib kis ntawm lub teeb, yog li ib qho siv hluav taws xob tsis tshua muaj nqi yog qhov xav tau. Qhov kev txwv tseem ceeb ntawm ib-hom kho qhov muag cable yog cov khoom tawg, thiab ib-hom kho qhov muag cable tuaj yeem tau txais qhov siab dav dav feem ntau yog siv laser, thaum LED yuav tawm ntau ntawm cov khoom siv hluav taws xob nrog ntau zaus thiab qhov dav tau muab tso rau, yog li cov khoom siv dispersion yog qhov tseem ceeb heev.
Piv nrog multimode fiber ntau, ib hom fiber ntau tuaj yeem txhawb cov kis mus ntev. Hauv 100Mbps Ethernet lossis 1g gigabit network, ib hom fiber ntau tuaj yeem txhawb ntau dua 5000m kis nrug.
Los ntawm cov nqi taw tes ntawm kev saib, vim tias qhov kho qhov muag dav dav yog kim heev, tus nqi ntawm kev siv ib hom fiber ntau tau siab dua qhov ntawm multimode fiber ntau cable. Ib hom fiber ntau yog siv qhov ntev thiab qhov loj muaj peev xwm ntawm kev sib txuas lus kho qhov muag fiber ntau, qhov kho qhov muag fiber ntau hauv cheeb tsam thaj chaw thiab ntau lub fiber ntau cov cim.
Xaiv
Lub ntsiab lus nominal loj ntawm ib hom fiber ntau yog (8 ~ 10) μ m / 125 μ m. Cov lus qhia tshwj xeeb (tus naj npawb ntawm cov xaum) suav nrog 2, 4, 6, 8, 12, 16, 20, 24, 36, 48, 60, 72, 84, 96 cores, thiab lwm yam. , hluav taws kub tsawg thiab hom tsis muaj halogen, tsis muaj pa taws thiab halogen tsis pub nplaim taws hom.
Thaum tus neeg siv muaj kev txwv tsis pub ua haujlwm rau lub kaw lus, thiab lub teeb liab tsis raug xa tawm, lossis lub kaw lus xa hluav taws xob tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua, tiv thaiv tooj liab xov tooj tseem ceeb tiv thaiv cov xov tooj hluav taws xob thiab cov khoom siv thaiv xov hluav taws xob yuav tsum raug siv, lossis cov kab hluav taws xob kho qhov muag yuav tsum siv
