Qhov kev sib kis deb ntawm lub network cable raug txwv, thiab nws tsis tuaj yeem daws qhov ntev ntawm cov ntaub ntawv xa mus ntev, yog li cov kab hluav taws xob siv tau rau kev xa xov ntev.
Optical fiber tau faib ua ntau hom thiab ib hom. Cov kis tau mus deb ntawm ntau hom yog farther dua network cable, tab sis luv dua hom ib hom.
Hauv 10mbps thiab 100mbps Ethernet, ntau hom fiber ntau tuaj yeem txhawb txog 2000 meters kis deb;
Hauv 1GbpS gigabit network, multimode fiber tuaj yeem pab txhawb kev sib kis mus txog li 550 meters;
Yog li no, ntau hom tam sim no siv tsawg dua.
Piv nrog rau ntau hom fiber ntau, tib hom fiber ntau tuaj yeem txhawb kev xa mus ntev. Los ntawm 100Mbps Ethernet mus rau 1G Gigabit network, ib hom fiber ntau tuaj yeem txhawb kis kev sib kis ntau dua 5000m.
Lub Cheebtsam siv nyob rau hauv hom ntau kho qhov muag tau siv ob zaug ntawm ntau hom kho qhov muag tau siv, yog li tus nqi them tag nrho ntawm cov hom kho qhov muag tau tshaj rau qhov siab tshaj qhov ntawm ntau hom kho qhov muag; cov kis nrug ntawm ib hom kho qhov muag dav dav tuaj yeem ncav cuag 150 txog 200 km.
Yog li no, cov hluav taws xob fiber ntau tuaj yeem siv rau kev sib kis ntev, xws li kev tswj xyuas qhov chaw deb.
