Muaj ntau hom fiber ntau optic cable.Qee hom yog ib hom, thiab qee hom yog multimode.Multimode fibers tau piav qhia los ntawm lawv cov core thiab cladding diameters.Feem ntau, txoj kab uas hla ntawm multimode fiber ntau yog 50/125 µm lossis 62.5/125 µm.Tam sim no, muaj plaub hom fiber ntau hom: OM1, OM2, OM3, OM4 thiab OM5.Cov tsiaj ntawv "OM" sawv rau optical multimode.Txhua hom ntawm lawv muaj cov yam ntxwv sib txawv.
Txuj
Txhua "OM" muaj qhov tsawg kawg nkaus Modal Bandwidth (MBW) yuav tsum tau.OM1, OM2, thiab OM3 fiber ntau yog txiav txim siab los ntawm ISO 11801 tus qauv, uas yog raws li cov qauv bandwidth ntawm multimode fiber ntau.Thaum Lub Yim Hli 2009, TIA / EIA tau pom zoo thiab tso tawm 492AAAD, uas txhais cov qauv kev ua haujlwm rau OM4.Thaum lawv tau tsim cov qauv "OM" thawj, IEC tseem tsis tau tshaj tawm cov qauv sib npaug uas tau pom zoo thaum kawg yuav raug sau tseg raws li hom fiber ntau A1a.3 hauv IEC 60793-2-10.
Specifications
● OM1 cable feem ntau tuaj nrog lub tsho txiv kab ntxwv thiab muaj cov tub ntxhais loj ntawm 62.5 micrometers (µm).Nws tuaj yeem txhawb nqa 10 Gigabit Ethernet ntawm qhov ntev txog 33 meters.Nws yog feem ntau siv rau 100 Megabit Ethernet daim ntawv thov.
● OM2 kuj muaj ib lub tsho tiv thaiv xim ntawm txiv kab ntxwv.Nws qhov loj me yog 50µm hloov 62.5µm.Nws txhawb 10 Gigabit Ethernet ntawm qhov ntev txog 82 meters tab sis feem ntau siv rau 1 Gigabit Ethernet daim ntawv thov.
● OM3 fiber ntau muaj lub tsho tiv thaiv xim ntawm aqua.Zoo li OM2, nws qhov loj me yog 50µm.Nws txhawb 10 Gigabit Ethernet ntawm qhov ntev txog 300 meters.Dhau li ntawm OM3 muaj peev xwm txhawb nqa 40 Gigabit thiab 100 Gigabit Ethernet mus txog 100 meters.10 Gigabit Ethernet yog nws qhov kev siv ntau tshaj plaws.
● OM4 kuj muaj lub tsho tiv thaiv xim ntawm aqua.Nws yog kev txhim kho ntxiv rau OM3.Nws kuj tseem siv 50µm core tab sis nws txhawb 10 Gigabit Ethernet ntawm qhov ntev txog 550 meters thiab nws txhawb 100 Gigabit Ethernet ntawm qhov ntev txog 150 meters.
● OM5 fiber ntau, tseem hu ua WBMMF (wideband multimode fiber), yog hom tshiab tshaj plaws ntawm multimode fiber ntau, thiab nws rov qab tau tshaj OM4.Nws muaj tib qhov loj me li OM2, OM3, thiab OM4.Cov xim ntawm OM5 fiber ntau lub tsho tau raug xaiv raws li txiv qaub ntsuab.Nws yog tsim thiab teev los txhawb tsawg kawg plaub WDM raws ntawm qhov tsawg kawg nkaus ceev ntawm 28Gbps ib channel los ntawm 850-953 nm qhov rais.Xav paub ntau ntxiv tuaj yeem pom ntawm: Peb Qhov Tseem Ceeb Tseem Ceeb ntawm OM5 Fiber Optic Cable
Txoj kab uas hla: Cov tub ntxhais txoj kab uas hla ntawm OM1 yog 62.5 µm, txawm li cas los xij, txoj kab uas hla ntawm OM2, OM3 thiab OM4 yog 50 µm.
