Txij li thaum OM1 thiab OM2 fibers tsis tuaj yeem txhawb nqa cov ntaub ntawv kis ceev ntawm 25Gbps thiab 40Gbps, OM3 thiab OM4 yog cov kev xaiv tseem ceeb rau ntau hom fibers uas txhawb 25G, 40G thiab 100G Ethernet.Txawm li cas los xij, raws li qhov yuav tsum tau muaj bandwidth nce, tus nqi ntawm fiber ntau optic cables los txhawb cov tiam tom ntej Ethernet ceev tsiv teb tsaws kuj tau nce siab dua.Hauv cov ntsiab lus no, OM5 fiber ntau tau yug los nthuav dav qhov zoo ntawm multimode fiber ntau hauv cov ntaub ntawv chaw.
Multimode fiber ntau optic cable qauv:
OM3 yog 50um core inch multimode fiber ntau optimized los ntawm 850nm laser.Hauv 10Gb / s Ethernet siv 850nm VCSEL, qhov sib kis ntawm fiber ntau tuaj yeem ncav cuag 300m;OM4 yog ib qho kev hloov kho tshiab ntawm OM3, OM4 multimode fiber ntau optimizes OM3 multimode fiber ntau Vim yog qhov sib txawv hom ncua (DMD) tsim thaum lub sij hawm kev sib kis ceev, qhov kev sib kis tau zoo heev, thiab qhov kev sib kis ntawm fiber ntau tuaj yeem ncav cuag 550m.
Qhov sib txawv tseem ceeb ntawm lawv yog nyob rau hauv 4700MHz-km, EMB ntawm OM4 fiber ntau tsuas yog teev raws li 850 nm, thaum OM5 EMB tus nqi tau teev tseg raws li 850 nm thiab 953 nm, thiab tus nqi ntawm 850 nm yog ntau dua OM4.Yog li, OM5 fiber ntau muab cov neeg siv nrog kev ncua ntev thiab kev xaiv fiber ntau.Tsis tas li ntawd, TIA tau xaiv cov txiv qaub ntsuab raws li lub tsho cable xim rau OM5, thaum OM4 yog lub tsho dej.OM4 yog tsim los rau 10Gb/s, 40Gb/s thiab 100Gb/s kis tau tus mob, tab sis OM5 yog tsim rau 40Gb/s thiab 100Gb/s kis tau tus mob, uas yuav txo tau tus naj npawb ntawm optical fibers rau high-ceev kis tau tus mob.
Tsis tas li ntawd, OM5 tuaj yeem txhawb nqa plaub SWDM raws, txhua tus nqa 25G cov ntaub ntawv, thiab siv ib khub ntawm multimode optical fibers los muab 100G Ethernet.Tsis tas li ntawd, nws yog siab tshaj OM3 thiab OM4 fibers.OM5 tuaj yeem siv rau kev teeb tsa hauv ntau qhov chaw ua haujlwm thoob ntiaj teb, los ntawm cov tsev kawm ntawv mus rau cov tsev mus rau cov chaw khaws ntaub ntawv.Nyob rau hauv luv luv, OM5 fiber ntau zoo dua OM4 nyob rau hauv cov nqe lus ntawm kis tau tus mob nyob deb, ceev thiab nqi.
General multi-mode fiber optic cable qauv piav qhia: Siv plaub-core multi-mode ua piv txwv, (4A1b yog 62.5/125µm, 4A1 yog 50/125µm).
