Tnws tsim kev sib piv ntawm OM1, OM2, OM3 thiab OM4 fiber

1. Cov tsoos OM1 thiab OM2 multimode optical fiber yog raws tus qauv LED (Lub Teeb Ua Haujlwm Diode) los ntawm cov qauv thiab qauv tsim.

Lub teeb ci qhov chaw loj, OM3 thiab OM4 tau kho kom zoo rau lub hauv paus ntawm OM2, raws li nws siv rau lub teeb ci LD (Laser Diode laser diode)

kis;

Piv nrog OM1 thiab OM2, OM3 muaj qhov sib kis thiab bandwidth ntau dua, yog li nws yog hu ua optimized multimode fiber lossis 10 Gigabit multimode fiber;

3, OM4 rov qab ua haujlwm tau zoo vim yog OM3, nrog kev ua tau zoo dua.

Sib piv cov nuj nqi thiab Nta ntawm OM1, OM2, OM3 thiab OM4 Optical Fibers

OM1: OM1: Cov tub ntxhais txoj kab uas hla thiab cov lej aperture yog qhov loj, thiab nws muaj lub zog sau tau muaj peev xwm thiab tiv taus khoov;

2. OM2: Ob qhov sib txawv ntawm cov taub thiab cov lej aperture yog qhov me me, uas ua rau txo cov qauv tawg ntawm cov xov paj fiber ntau, uas ho nce cov bandwidth thiab txo cov nqi tsim khoom.

1/3;

3, OM3: Kev siv cov nplaim hluavtaws tiv thaiv cov tawv nqaij sab nraud tuaj yeem tiv thaiv kev sib kis ntawm cov nplaim hluav taws, tiv thaiv cov pa taws, pa roj thiab cov pa lom, thiab lwm yam, thiab ua tau raws li qhov sib kis ntawm 10 gb / s

Qhov kev xav tau

OM4: OM4: Tsim rau VSCEL laser kis, qhov ua tau zoo bandwidth yog ntau tshaj ob npaug ntawm OM3.

Daim ntawv thov sib piv ntawm OM1, OM2, OM3 thiab OM4 fiber

OM1 thiab OM2 tau dav siv hauv cov ntawv thov hauv tsev rau ntau xyoo, txhawb Ethernet xa mus txog 1GB;

OM2 thiab OM4 kho qhov muag kab hluav taws xob feem ntau yog siv hauv cov ntaub ntawv chaw tsim hluav taws xob ib puag ncig, txhawb 10G lossis txawm tias 40 / 100G high-speed Ethernet xa.

Thaum twg yuav tsum siv OM3 fiber dhia ua ke?

OM3 fiber ntau yog kho qhov muag tau tsim los ua haujlwm ua ke nrog VCSEL. Nws ua raws li ISO / IEC11801-2nd OM-3 fiber ntau lub zog thiab ua raws li 10 Gigabit Ethernet.

Daim ntawv thov xav tau. Muaj ntau hom OM3 fiber ntau, suav nrog hom sab hauv, sab hauv tsev / sab nraum zoov sab nraud, thiab lwm yam. Cov lej ntawm cov roj carbon fiber ntau yog li 4 txog 48 cores. Kuj txhawb

Muaj cov ntawv thov raws li cov qub multimode 50/125 fiber, nrog rau kev txhawb nqa rau cov kab hluav taws xob LED thiab cov teeb ci laser.

1. Qhov kev sib kis deb ntawm Gigabit Ethernet siv OM3 optical fiber ntau zog tuaj yeem txuas ntxiv mus txog 900 metres, uas txhais tau tias thaum qhov kev ncua deb ntawm cov tsev siab tshaj 550 meters, cov neeg siv

Nws tsis tas yuav siv cov khoom siv laser kim. Zh

2. Hauv qhov ntau ntawm 2,000 metres, OC-12 (622Mb / s) cov kab nrawm dua tuaj yeem siv tus qauv 62.5 / 125μm multimode fiber.

Sab nraud, ib hom siv fiber ntau. Txawm li cas los xij, kev rov tshwm sim ntawm OM3 multimode fiber tau hloov qhov xwm txheej no, vim OM3 fiber ntau tuaj yeem txhim kho kev ua haujlwm ntawm Gigabit thiab 10G systems.

Kev xa mus deb, tus qauv siv kho qhov muag siv lub nthwv dej ntawm 850nm thiab txhawb nqa kev siv VCSEL, tus nqi sib cuam tshuam cov phiaj xwm zoo tshaj. Zh

3. Thaum qhov txuas ntev tshaj li 1000 metres, ib hom fiber ntau tseem yog qhov kev xaiv tsuas yog tam sim no. Ib hom fiber ntau tuaj yeem siv ntawm qhov ntev ntawm 1310nm hauv lub gigabit system.

Ua tiav 5 km kis deb, xa mus deb li ntawm 10 km tiav hauv Gigabit system.

4. Thaum qhov kev sib txuas ntev yog tsawg dua lossis sib npaug li 1000 metres, OM3 50 μm multimode fiber ntau tuaj yeem siv rau hauv Gigabit system, thiab nws yuav tsum siv rau hauv 10 Gigabit system.

Ib hom fiber ntau.

5. Thaum qhov txuas ntev ntev tsawg dua 300 metres, OM3 multimode fiber ntau tuaj yeem siv rau hauv txhua lub Gigabit thiab 10 Gigabit systems.

Wpoj qaib siv OM4 fiber ntau lub tshuab dhia?

Rau qhov txuas sib txuas, tus nqi ntawm qhov khoos phis tawj kho qhov muag yog kwv yees kim heev. Txawm hais tias tus nqi ntawm ib hom fiber ntau yog pheej yig dua li multimode fiber, tab sis ib hom kho qhov muag

Yuav tsum siv cov khoom kim heev 1300nm optical module, uas yog kwv yees 2-3 zaug tus nqi ntawm 850nm multimode optical module, tag nrho, ib qho multimode optical fiber

Qhov kev tsim tus nqi qis dua li ib hom kab ke fiber ntau.

Thaum nqis peev hauv fiber ntau optic cabling, yog tias koj tuaj yeem txiav txim siab nce kev nqis peev thawj zaug hauv qee cov cabling, siv cov fiber ntau zoo, xws li OM4 fiber, tuaj yeem xyuas kom meej

Tso cai rau tag nrho cov txiaj ntsig ntawm kev siv tshuab fiber ntau kho qhov muag tam sim no, txo tag nrho tus nqi ntawm qhov kev ua haujlwm tam sim no; thaum lub zog xav tau kev txhim kho kom zoo dua rau cov kev ua haujlwm siab dua, xws li 40G thiab

100G lub sijhawm, tom qab ntawd koj tuaj yeem siv ib qho OM4 thiab tus nqi ntau dua.

Hauv ntej, thaum kis tau tus mob ntau dua 1Gb / s, kev siv cov roj carbon fiber ntau yog qhov kev xaiv zoo. Thaum lub kaw lus xav tau qhov ua kom sib kis tau zoo dua, cov hauv qab no

Nov yog peb cov lus qhia rau xaiv OM4 fiber ntau:

1. Rau cov neeg siv Ethernet, hauv 10Gb / s qhov system xa, kis mus deb tuaj yeem ncav cuag 300m txog 600m; hauv 40Gb / s thiab 100Gb / s system, kis nrug

Qhov deb yog 100m txog 125m.

2. Rau cov neeg siv thaj tsam sab nraud, OM4 fiber ntau yuav txhawb nqa 4Gb / s fiber ntau qhov txuas ntev ntawm 400m, 8Gb / s fiber ntau txuas ntev ntawm 200m lossis 16Gb / s fiber ntau txuas

Qhov ntev yog 130m.
