Muaj ntau hom ntau hom fiber ntau multimode muaj nyob rau kev sib txuas rau high-speed network, thiab txhua tus muaj peev xwm sib txawv thiab peev txheej. Muaj ntau txoj kev xaiv, nws muaj peev xwm ua tau yooj yim los xaiv cov khoom siv ntau hom multimode. OM1 vs OM2 vs OM3 vs OM4 vs OM5, uas xaiv? Koj tuaj yeem tau cov lus teb rau hauv daim ntawv no.
Multimode Fiber ntau npaum li cas?
Multimode fiber ntau (MMF) yog ib hom fiber ntau qhov siv los ua kev sib txuas lus kom ntev, piv txwv, hauv tsev lossis hauv tsev kawm ntawv. Multimode fiber optic cable muaj tub ntxhais loj, feem ntau 50 lossis 62.5 microns uas ua rau ntau lub teeb hom kom tau txais kev qhia. Vim li no, ntau cov ntaub ntawv muaj peev xwm dhau los ntawm multimode fiber ntau hauv ib lub sij hawm muab. Qhov siab tshaj plaws kis mus rau MMF cable yog ncig 550m ntawm kev ceev ntawm 10Git / s. Nws tuaj yeem xa tawm mus deb ntawm cov nqi qis, xws li mus txog 2km ntawm 100Mb / s.
Muaj Ntau hom Multimode Fiber ntau npaum li cas?
Kev pom zoo los ntawm ISO 11801 tus qauv, cov kab mob fiber ntau hauv fiber ntau tau muab cais ua OM1 fiber, OM2 fiber ntau, OM3 fiber, OM4 fiber ntau thiab khov tshiab OM5 fiber. Ib sab tom ntej no yuav piv cov qauv ntawm cov tub ntxhais qhov loj, kev siv bandwidth, cov ntaub ntawv tus nqi, nrug, xim thiab kho qhov muag los ntawm cov ntsiab lus.
OM1 Fibre
