GG quot; OM" sawv rau optical ntau hom, uas yog, hom kho qhov muag, yog tus qauv rau ntau hom fiber ntau los qhia qib fiber ntau. Qhov bandwidth thiab qhov siab tshaj plaws ntawm kev sib kis sib txawv yog txawv. Kab lus no tsuas yog piav qhia qhov txawv ntawm OM1, OM2, OM3 thiab OM4 fiber.
1.OM1 hais txog 50um lossis 62.5um tseem ceeb ntawm cov roj carbon fiber ntau multimode fiber ntau nrog kev txhaj tshuaj tag nrho ntawm 850 / 1300nm siab tshaj 200 / 500MHz.km.
2. OM2 yog hais txog 50um lossis 62.5um tub ntxhais qhov taub multimode fiber ntau nrog 850 / 1300nm tag nrho kev txhaj tshuaj raws li 500 / 500MHz.km.
3. OM3 yog 50um core diameter multimode fiber ntau zoo los ntawm 850nm laser. Hauv 10Gb / s Ethernet siv 850nm VCSEL, kev xaib fiber ntau tuaj yeem ncav cuag 300m.
4. OM4 yog kev hloov kho tshiab ntawm OM3 multimode fiber ntau, thiab cov kis fiber ntau tuaj yeem ncav cuag li 550m.
Tsim ntawm cov qauv
1.Txoj kev ywj pheej OM1 thiab OM2 multimode fiber ntau raws li LED (Lub teeb Emitting Diode) hauv tus qauv thiab tsim qauv, thaum OM3 thiab OM4 tau kho kom zoo rau lub hauv paus ntawm OM2, ua rau lawv tsim nyog rau lub teeb ci tib lub sijhawm LD (Laser Diode laser diode ) kis
2. Piv nrog OM1 thiab OM2, OM3 muaj qhov sib kis thiab bandwidth ntau dua, yog li nws yog hu ua optimized multimode fiber lossis 10G multimode fiber.
3. OM4 tau ua kom zoo rau lub hauv paus ntawm OM3 thiab muaj kev ua tau zoo dua.
