Qee cov neeg siv khoom tsis tuaj yeem paub tseeb tias hom multimode fiber ntau lawv xav tau xaiv.Hauv qab no yog cov ntsiab lus ntawm ntau hom rau koj siv.
Muaj ntau pawg ntawm graded-index multimode iav fiber ntau cables, suav nrog OM1, OM2, OM3 thiab OM4 cables (OM stands rau optical multi-mode).
OM1 qhia txog 62.5-micron cable thiab OM2 qhia txog 50-micron cable.Cov no feem ntau siv hauv cov ntawv thov hauv tsev kom luv dua 1Gb / s tes hauj lwm.Tab sis OM1 thiab OM2 cable tsis haum rau niaj hnub no kev sib txuas ceev dua.
OM3 thiab OM4 yog ob qho tib si laser-optimized multimode fiber ntau (LOMMF) thiab tau tsim los kom haum rau kev sib txuas lus fiber ntau sai xws li 10, 40, thiab 100 Gbps.Ob leeg yog tsim los siv nrog 850-nm VCSELS ( ntsug-kab noj hniav nto-emitting lasers) thiab muaj aqua sheaths.
OM3 qhia txog 850-nm laser-optimized 50-micron cable nrog rau kev ua haujlwm zoo bandwidth (EMB) ntawm 2000 MHz / km.Nws tuaj yeem txhawb 10-Gbps txuas mus txog 300 meters.OM4 qhia txog lub high-bandwidth 850-nm laser-optimized 50-micron cable ib tug zoo modal bandwidth ntawm 4700 MHz / km.Nws tuaj yeem txhawb nqa 10-Gbps txuas qhov deb ntawm 550 meters.100 Gbps nrug yog 100 meters thiab 150 meters, feem.
