Qhov tsis sib piv
1. Om1 hais txog kev txhaj tshuaj tag nrho ntawm 200/500 thaum 850 / 1300nm MHz.km 50um lossis 62.5um tseem ceeb ntawm cov roj hmab fiber ntau;
2. Om2 hais txog 850 / 1300nm tag nrho txoj kev txhaj tshuaj qhov txhab ntawm 500/500 MHz.km 50um lossis 62.5um tub ntxhais qhov ntev multimode fiber;
3. OM3 yog 50um core diameter multimode fiber ntau zoo los ntawm 850nm laser. Hauv 10Gb / s Ethernet nrog 850nm VCSEL, qhov kho qhov muag hluav taws xob kis tau mus deb tuaj yeem ncav cuag 300m;
4. OM4 yog kev hloov kho tshiab ntawm OM3 multimode fiber ntau, thiab cov kab ke xa hluav taws xob fiber ntau tuaj yeem ncav cuag li 550m
Sib piv cov haujlwm thiab nta
1. Om1: nrog cov tub ntxhais loj dua thiab muaj lub zog loj, nws muaj lub zog sau lub zog zoo thiab khoov tsis kam;
2. Om2: lub ntsiab taub thiab cov zauv loj me me, uas zoo txo cov hom dispersion ntawm fiber ntau, ua kom nce bandwidth thiab txo tus nqi ntau lawm los ntawm 1/3;
3. OM3: nplaim taws nplaim hluav taws tuaj yeem tiv thaiv kev sib kis ntawm cov nplaim taws, pa taws, kua roj acid thiab roj lom, thiab ua tau raws li qhov xav tau ntawm 10 GB / s kis tus nqi;
4. OM4: tsim rau vscel laser kis tau tus mob, qhov ua tau zoo bandwidth yog ntau dua ob zaug ntawm OM3.
Daim Ntawv Thov Sib Piv
1. Om1 thiab om2 tau dav dav hauv tsev rau ntau xyoo, txhawb nqa tus nqi siab kawg ntawm 1GB Ethernet xa;
2. OM3 thiab OM4 optical cables feem ntau siv hauv cov ntaub ntawv chaw cabling ib puag ncig, txhawb 10g lossis txawm tias 40 / 100g high-speed Ethernet xa.
OM3 fiber yog tsim los ua haujlwm nrog VCSEL kom tau raws li cov cai ntawm 10 Gigabit Ethernet kev siv. Muaj ntau hom OM3 optical fiber, suav nrog hom sab hauv, sab hauv tsev / sab nraum zoov sab nraud, thiab lwm yam. Cov naj npawb ntawm cov khoom siv fiber ntau yog li ntawm 4 txog 48. Tsis tas li ntawd, nws kuj txhawb txhua daim ntawv thov raws cov qub multimode 50/125 fiber ntau, suav nrog LED lub teeb thiab lub teeb ci.
OM4 fiber ntau tuaj yeem siv tag nrho ntawm cov thev naus laus zis fiber ntau thev naus laus zis tam sim no thiab txo tus nqi tag nrho ntawm qhov kev ua haujlwm tam sim no; thaum lub zog xav tau kev txhim kho kom muaj kev hloov dua siab dua, xws li 40g thiab 100g, OM4 tseem tuaj yeem siv thiab yuav txuag nqi ntau dua. Hauv ib lo lus, thaum kis tau tus mob ntau dua 1GB / s, siv multimode fiber yog qhov kev xaiv zoo.
