Ib hom vs Multimode Fiber FAQs

Q: Ntev npaum li cas ib hom fiber ntau tuaj yeem mus?

A: Rau feem ntau daim ntawv thov, qhov siab tshaj plaws ntawm ib hom cable yog nyob ib ncig ntawm 160 kilometers. Txawm li cas los xij, cov fibers dispersion-compensating tuaj yeem txhawb ntau tshaj 200 mais.

Q: Ntev npaum li cas multimode fiber ntau mus?

A: Nws txawv nrog cov ntaub ntawv ceev thiab fiber ntau hom. Siv cov OM2 ua piv txwv. Nws txhawb qhov siab tshaj plaws ntawm 550m ntawm 1Gbps thiab 82m ntawm 10Gbps. Txawm li cas los xij, qhov kev ncua deb tshaj plaws rau tag nrho cov multimode fibers yuav tsawg dua 2km.

Q: Dab tsi yog qhov lees txais dB poob rau ib hom fiber ntau?

A: Raws li EIA/TIA 568, SMF poob yog nyob ib ncig ntawm 0.5dB/km rau 1310nm qhov chaw thiab 0.4dB/km rau 1550nm qhov chaw.

Q: Dab tsi yog qhov lees txais dB poob rau multimode fiber ntau?

A: Raws li EIA / TIA 568, MMF poob yog nyob ib puag ncig 3dB / km rau 850nm qhov chaw thiab 1dB / km rau 1300nm qhov chaw.

Q: Kuv puas tuaj yeem siv multimode fiber ntau nrog ib hom?

A: Tsis yog, koj ua tsis tau. Vim tias lawv muaj cov kab sib txawv ntawm cov tub ntxhais sib txawv thiab xa ntau hom teeb pom kev sib txawv, sib tov ob lub fibers los yog txuas ncaj qha yuav ua rau muaj qhov tsis zoo ntawm qhov muag, uas ua rau muaj qhov sib txuas flapping lossis nqes mus.

Q: Koj puas txheeb xyuas ib hom thiab multimode fiber ntau li cas?

A: Txheeb xyuas cov fiber ntau nrog cov tsho sib txawv. Yellow stands rau Tib hom, thaum Txiv kab ntxwv los yog Aqua sawv rau multimode.

Q: Kuv puas tuaj yeem siv ib hom fiber ntau rau qhov luv luv?

A: Yog, nws yuav yog. Txawm li cas los xij, koj yuav tsum ntxiv qhov tsim nyog kho qhov muag kom tsis txhob overloading lossis ua rau lub receiver puas.

Q: Puas tuaj yeem txhawb nqa multimode fiber ntau 10gb?

A: Tag nrho cov multimode fiber txhawb 10Gb, tab sis qhov kev sib txuas sib txawv nyob ntawm cov ntaub ntawv ceev. OM1 tsuas yog txhawb nqa max ntawm 33m, thiab OM2 txhawb 82m. Yog li, nws tsis pom zoo kom siv OM1 thiab OM2 rau 10G tes hauj lwm. Siv qib siab OM3, OM4, lossis OM5 fiber ntau rau 10Gb tes hauj lwm zoo dua.

Q: Puas tuaj yeem siv lub tshuab hluav taws xob multimode nrog ib hom fiber ntau?

A: Feem ntau, tsis yog. Ib qho tseem ceeb kho qhov muag poob yuav tshwm sim yog hais tias ib tug multimode transceiver txuas nrog ib hom fiber ntau. Txawm li cas los xij, qhov rov qab yuav ua haujlwm. Piv txwv li, siv hom txias fiber ntau cable, 1000BASE-LX ib hom transceiver tuaj yeem ua haujlwm ntawm ntau hom fiber ntau nrog txo qhov nrug.

Q: Puas yog ib hom zoo dua li multimode fiber ntau?

A: Feem ntau, ib hom fiber ntau muab kev ua haujlwm zoo dua thiab siv dav. Txawm li cas los xij, peb tsis tuaj yeem hais tias nws zoo dua li multimode fiber ntau vim nws cov nqi thiab qhov zoo ntawm daim ntawv thov. Yog li ntawd, koj yuav tsum xaiv qhov zoo tshaj plaws raws li koj daim ntawv thov thiab pob nyiaj siv.
