Nws paub tias ib hom fiber ntau tau haum rau cov ntawv thov ntev, thaum multimode fiber ntau kho qhov muag tau tsim rau kev khiav haujlwm luv. Tom qab ntawd thaum nws los txog rau ib hom vs multimode fiber ntau nrug, dab tsi yog qhov ntau thiab tsawg txawv?
Los ntawm daim ntawv qhia, peb tuaj yeem pom tias ib hom fiber ntau qhov nrug deb ntev dua li ntawm multimode fiber cables ntawm cov ntaub ntawv tus nqi ntawm 1G txog 10G, tab sis OM3 / OM4 / OM5 multimode fiber ntau txhawb cov ntaub ntawv ntau dua. Vim hais tias multimode optical fiber muaj qhov loj loj qhov loj thiab txhawb ntau dua ib lub teeb hom, nws txoj kab hluav taws xob nyob deb yog txwv los ntawm modal dispersion uas yog qhov tshwm sim hauv multimode kauj ruam-index fiber. Thaum uas ib hom fiber ntau tsis yog. Qhov ntawd yog qhov tseem ceeb ntawm lawv. Ntxiv rau, OS2 ib hom fiber ntau yuav tuaj yeem txhawb ntev dua hauv 40G thiab 100G sib txuas, uas tsis tau teev npe hauv cov lus.
