Kev faib tawm fiber ntau
Optical fiber tau faib ua ntau hom raws li cov khoom sib txawv, tuaj yeem faib ua hom:
(1) Raws li tus naj npawb ntawm cov kis tau tus mob, nws muaj peev xwm raug faib ua hom ib hom fiber ntau thiab ntau hom fiber ntau. Ib hom fiber ntau muaj cov tub ntxhais me txoj kab uas hla, ua haujlwm ntawm lub sijhawm muab lub suab yoj, thiab tuaj yeem sib kis hauv tib hom, nrog cov kis dav dav thiab cov kis loj. Ntau hom fiber ntau tuaj yeem xa tawm hauv ntau hom ntawm qhov muab kev khiav haujlwm wavelength. Piv nrog hom fiber ntau, ntau hom fiber ntau muaj qhov kis tau zoo.
(2) Raws li kev faib tawm ntawm cov roj hmab refractive index, nws tuaj yeem muab faib ua hom dhia thiab cov fiber ntau. Qhov ntsuas refractive ntawm jumper fiber core thiab refractive index ntawm kev tiv thaiv txheej txheej yog ob qho tas li, thiab cov qib fiber ntau cov tub ntxhais kawm nce nrog qhov nce ntawm qhov hluav taws xob.
