OM5 fiber ntau optic yog dab tsi?
OM5 fiber ntau optic yog ib qho tshiab ntawm ntau hom fiber ntau optic cable tsim los rau siab bandwidth hla luv mus rau nruab nrab. Nws yog thawj qhov kev pom zoo dav dav multimode fiber ntau (WBMMF) ua raws li ISO 11801 thib peb tsab thiab TIA-568.0-D cov qauv luam tawm xyoo 2017. OM5 fiber ntau feem ntau ua haujlwm hauv lub wavelength ntawm 850 txog 953 nanometers thiab txhawb tsawg kawg yog plaub qhov sib txawv wavelengths. Qhov kev ncua ntev wavelength no tso cai rau ntau txoj kev xa mus ib txhij ntawm tib lub fiber ntau siv cov tshuab luv wavelength division multiplexing (SWDM) technology. Raws li tus naj npawb ntawm fibers txo, yog li crosstalk thiab tag nrho poob. Cov xim ntawm OM5 yog txiv qaub ntsuab sab nrauv sheath, thiab cov geometry (50μm core, 125μm cladding) yog tib yam li OM3 thiab OM4, ua rau OM5 optical cable rov qab sib xws nrog OM3 thiab OM4 optical fibers. Txhawb 100Gb/s, 200Gb/s, thiab 400Gb/s network kis tau tus mob tshaj 150 meters, nws yog thawj qhov kev xaiv rau scenarios uas yuav tsum tau high-kev ua tau zoo tso zis kis tau tus mob.
SWDM yog dab tsi?
Shortwave data center kev sib txuas feem ntau yog siv los ntawm VCSELs ua haujlwm ntawm wavelengths ze rau 850 nm. Shortwave wavelength division multiplexing (SWDM) yog ib lub tshuab siv plaub lub wavelengths nyob rau hauv thaj tsam 850 txog 950 nm. Lub SWDM transceiver yog tsim los siv 2 fiber ntau txuas rau lub transceiver nrog OM5 multimode fiber ntau.
Dab tsi yog qhov txawv ntawm OM5 optical fiber thiab OM3 thiab OM4 optical fiber ntau?
Thaum ntsuas kev sib txuas lus luv luv, OM5, OM3, thiab OM4 yog cov kev xaiv tseem ceeb nrog cov yam ntxwv tshwj xeeb. Nov yog li cas cov fibers multimode sib piv:
Bandwidth thiab kis nrug deb
OM5 Fiber muaj ntau dua bandwidth piv rau OM3 thiab OM4, yog li txhawb cov ntaub ntawv ntau dua. Qhov no yog tshwj xeeb tshaj yog muaj txiaj ntsig nyob rau hauv cov xwm txheej uas yuav tsum tau ua kom muaj txiaj ntsig zoo, ua rau nws xaiv thawj zaug rau cov ntawv thov uas xav tau cov ntaub ntawv ntau dua. OM5 muaj tib qhov siab tshaj plaws nyob deb li OM4 rau txhua qhov tam sim no thiab yav tom ntej multimode IEEE daim ntawv thov (xws li 40GBase-SR4 thiab 100GBase-SR4). OM5 yog ua ke nrog 40G-SWDM4 lossis 100G-SWDM4 optical modules. Piv nrog OM4 thiab OM3, qhov sib kis tau zoo dua.
Channel poob thiab crosstalk
OM5 optical cable ua haujlwm nyob rau hauv lub wavelength ntau ntawm 850 rau 950nm thiab tuaj yeem muab 100GB ntawm cov ntaub ntawv ntws siv tsuas yog ib khub ntawm cov khoom sib txuas ntawm cov khoom siv kho qhov muag. Tsawg fibers txhais tau tias tsawg dua crosstalk thiab qis dua tag nrho. Lub attenuation ntawm OM5 broadband multimode fiber ntau tau raug txo mus rau 3.0 dB / km ntawm 3.5 dB / km ntawm yav dhau los OM3 thiab OM4 cables.
kev xav txog tus nqi
Qhov tseeb, OM5 cabling nqi kwv yees li 50% ntau dua OM4. Tsis tas li ntawd, nrog rau kev yuav khoom loj ntawm silicon photonics thev naus laus zis thiab cov ntaub ntawv loj-loj ultra-loj-loj cov chaw zov me nyuam, tus nqi ntawm ib hom kev kho qhov muag tau poob qis, thiab ntau thiab ntau tus neeg siv yuav nyiam xaiv ib hom kho qhov muag. modules. Piv txwv li, 100GBase-PSM4 tus nqi tsuas yog $ 750 siv ib hom MTP qaum qaum cable uas tuaj yeem txhawb nqa 500 meters ntawm kev sib kis.
Puas yog OM5 fiber ntau tshaj OM3 thiab OM4 fiber ntau?
yeej yog. OM5 fiber ntau yog tsim los nrog 50 micron core loj, ua rau nws sib xws nrog OM4 thiab OM3 fiber optic cables. Qhov kev sib raug zoo no tau tshwm sim los ntawm lawv qhov sib koom ua ke, ua kom muaj kev sib koom ua ke zoo thiab yooj yim hauv kev tsim network. Qhov no txhais tau hais tias yog tias koj muaj cov txheej txheem uas twb muaj lawm siv OM4 lossis OM3, koj tuaj yeem qhia OM5 jumpers los txhim kho kev ua tau zoo yam tsis tas yuav hloov tag nrho cov kab ke. Qhov kev sib raug zoo rov qab no ua rau muaj kev cuam tshuam thiab raug nqi rau kev hloov kho network. Txawm li cas los xij, kev tswj hwm kev ua raws li tag nrho cov khoom siv, suav nrog cov khoom sib txuas thiab cov khoom siv sib txuas, nrog rau cov qauv siv fiber ntau yog qhov tseem ceeb rau kev ua kom pom kev ua tau zoo thiab kev ntseeg siab ntawm lub network.
Dab tsi ntawm cov connectors muaj rau OM5 fiber optics?
OM5 cables tuaj nrog ntau yam kev sib txuas nrog rau LC, SC, ST thiab MTP / MPO. Qhov kev xaiv ntawm connector nyob ntawm seb cov kev cai tshwj xeeb ntawm lub network thiab cov cuab yeej siv. FS's OM5 optical fiber txhawb nqa ntau yam kev sib txuas thiab tuaj yeem hloov kho raws li cov xwm txheej sib txawv kom tau raws li ntau yam kev xav tau.
Dab tsi optical modules tau tshaj OM5 fiber ntau?
OM5 Fiber yog sib xws nrog ntau yam ntawm optical transceivers los yog modules uas txhawb multimode fiber ntau sib txuas. Module xaiv nyob ntawm seb cov kev cai tshwj xeeb ntawm cov khoom siv network thiab daim ntawv thov. Qee cov khoom siv kho qhov muag tau sib xws nrog OM5 cables suav nrog:
1. SR4 (Short Reach 4) Modules: Cov qauv no yog tsim los rau cov ntaub ntawv ntau dua thiab feem ntau yog siv hauv 40/100 Gigabit Ethernet (40/100GbE).
2. SR8 (Short Range 8) module: SR8 module yog siv rau kev sib txuas siab thiab txhawb nqa 400 Gigabit Ethernet (400GbE). Nws yog tsim rau cov xwm txheej uas yuav tsum tau ceev thiab siab bandwidth hauv cov chaw zov me nyuam thiab kev lag luam network.
3. SWDM4 (Short Wavelength Division Multiplexing 4-}channel) module: Zoo tagnrho rau cov xwm txheej uas xav tau kev sib txuas siab thiab kev ua haujlwm siab, nws tuaj yeem siv los txhawb 40/100 Gigabit Ethernet (40/100GbE) daim ntawv thov.
Thaum xaiv OM5 cable module, koj yuav tsum xyuas kom muaj kev sib raug zoo nrog cov khoom sib txuas tshwj xeeb ntawm thaj chaw qaum (xws li LC, SC, MTP / MPO) thiab cov khoom siv network siv. Nco ntsoov xa mus rau cov lus qhia tshwj xeeb uas muab los ntawm cov tuam txhab module thiab cable kom ntseeg tau tias muaj kev sib raug zoo thiab kev ua haujlwm zoo.
Puas yog cov qauv kev sib txuas lus kho qhov muag xws li Ethernet thiab Fiber Channel qhia OM5?
Tsis muaj kev sib kis tus qauv qhia rau OM5 lossis SWDM. Cov qauv kis tau tus mob feem ntau suav nrog tsuas yog ib qho kev hloov pauv ntawm multimode fiber ntau xaiv raws li kev lag luam, kev lag luam thiab kev ua haujlwm. Kev sib kis sib kis yog qhov txawv ntawm multimode fiber ntau rau cov ntaub ntawv tus nqi Ntau dua lossis sib npaug rau 40G.
OM5 Multimode Fiber vs OM5 Multimode Fiber Tib Hom Fiber: Ib qho twg xaiv?
Txawm hais tias tus nqi ntawm ib hom fiber ntau (SMF) tau poob qis tsis ntev los no vim yog siv cov thev naus laus zis tshiab, tus nqi ntawm cov fiber ntau pluggable tseem txwv kev siv SMF hauv cov ntaub ntawv chaw. Nyob rau hauv sib piv, OM5 muaj peev xwm multiplex plaub wavelengths nyob rau hauv lub 850nm rau 953nm ntau yam, ua kom cov ntaub ntawv muaj peev xwm plaub npaug thiab txo cov nqi fiber ntau. Tsis tas li ntawd, MMF muaj qhov zoo hauv kev teeb tsa, kev daws teeb meem, kev tu, thiab kev saib xyuas tag nrho, ua rau nws xaiv zoo dua rau cov chaw zov me nyuam cov ntaub ntawv. Qhov teeb meem nrog MMF, txawm li cas los xij, yog nyob deb. Thiab qhov siab tshaj plaws nrug txo qis thaum cov ntaub ntawv ceev nce. Multimode fiber ntau yog li muaj txiaj ntsig ntau dua rau cov tswv network tshaj li 500m kev ncua deb, thaum OM5 tso cai rau kev tsiv teb tsaws mus rau 400Gbps tshaj 150m deb. Rau cov ntawv thov tshaj 500m, ib hom fiber ntau yuav tsum raug xaiv.
