OM5 fiber ntau kis deb npaum li cas?

Optical fiber technology yog xub tsim rau cov ntaub ntawv nruab nrab cov ntaub ntawv. Los ntawm cov kev txhim kho tam sim no, nws yuav dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tsim kom muaj lub network qaum.
Nrog rau kev txhim kho thiab siv cov thev naus laus zis wireless, kab rov tav xov thaiv kab rov tav hauv cov tsev lag luam thiab chaw tsim khoom tau dhau 1Gbps, thiab qhov ua kom tau txais yog qhov sib txuas ntawm cov xov kab txuas ua ke txhawb kev nrawm ntawm tsawg kawg 40Gbps thiab 100Gbps. Qhov no txhais tau tias qhov kev siv siab ntwm cov ntawv txhawb nqa cov ntaub ntawv chaw yog haum rau kev tsim kho thiab kev thov tam sim no. Optical fiber OM5 broadband tsis tuaj yeem tsuas txhawb 802.11ac wi-nkaus tshuab, tab sis kuj tseem txhawb nqa high-density 5G wireless network.

Cov kev paub theem pib ntawm high-density OM5 fiber
Cov koom haum ISO thiab TIA tshaj tawm tau tso tawm cov xov hluav taws xob tseeb 11801 koob thib 3 thiab TIA-568.0-D xyoo 2017, feem.
OM5 Broadband Multimode Optical Cable: lub attenuation yog txo los ntawm 3.5 dB / km ntawm yav dhau los OM3 thiab OM4 kho qhov muag hluav taws xob rau 3.0 dB / km. Tsis tas li ntawd, qhov yuav tsum tau muaj bandwidth nyob nthwv dej ntawm 953 nm yog nce. Qhov ntsuas ntsuas ntawm OM5 (50μm tub ntxhais xov hlau, 125 clm cladding) yog tib yam li OM3 thiab OM4, yog li nws tau rov qab sib haum nrog cov hom kho qhov muag.
OM5 fiber ntau kuj txhawb yav tom ntej 400G Ethernet. Rau kev kub ceev ntau dua 400G Ethernet ntawv thov xws li 400G Puag-SR4.2 (4 khub ntawm fiber ntau 2 wavelengths, txhua channel siv 50G PAM4) lossis 400G Puag-SR4.4 ((4 Rau 4 wavelengths ntawm fiber ntau, txhua channel siv 25GNRZ), tsuas yog 8-core OM5 fiber yog qhov yuav tsum tau. OM5 fiber yog laser-optimized multimode fiber (MMF), uas qhia meej cov bandwidth cov yam ntxwv rau wavelength faib multiplexing (WDM). Lub hom phiaj ntawm hom kab ke fiber ntau tshiab no yog los muab kev txhawb nqa rau ntau yam "luv" wavelengths ntawm 850nm thiab 950nm, thiab wavelengths hauv cov kab ntawv no yog tsim rau cov kev siv zoo-txuas ua ke tom qab polymerization.

Dab tsi yog qhov sib txawv ntawm OM5 fiber jumper thiab OM3 / OM4 fiber ntau jumper?
1. Sab nraud sheath xim: Feem ntau hais lus, cov xim sab nraud xim xim ntawm OM3 thiab OM4 fiber ntau cov khoom siv yog cov xim turquoise lossis ntshav, thiab cov xim sab nrauv xim ntawm OM5 fiber dhia lub luag haujlwm yog aqua.
2. Wavelength: Qhov ua haujlwm nthwv hluav taws xob ntawm OM5 fiber jumper yog 850 / 1300nm, thiab tuaj yeem txhawb tsawg kawg 4 wavelengths. Kev khiav hauj lwm wavelengths OM3 thiab OM4 ib txwm yog 850nm thiab 1300nm. Nyob rau tib lub viav vias sib ntev, qhov sib kis tau ntawm qhov no multimode fiber ntau jumper kuj tseem muaj qhov sib txawv.
3. Kev ua haujlwm hom bandwidth (EMB): OM5 fiber thaj txuas muaj qhov sib tsoo ntau dua hauv hom ua tau zoo bandwidth (EMB), nws yuav ua rau kom muaj txiaj ntsig hom bandwidth (EMB) ntawm 850nm wavelength rau 6000MHZ.km, nyob ib ncig ntawm 880nm wavelength Nws nce mus txog 8000MHZ. km, uas yog deb tshaj li tsoos OM3 thiab OM4 multimode fiber ntau lub tsev.

Dab tsi yog qhov zoo ntawm OM5 fiber jumper?
Qib siab ntawm kev lees paub: OM5 fiber jumper yog Ameslikas tso tawm raws li TIA-492AAAE los ntawm Kev Lag Luam Sib Txuas Kev Lag Luam, thiab tau pom zoo ua ke hauv ANSI / TIA-568.3-D kev kho dua qhov kev xav tawm los ntawm Asmeskas National Standards Institute;
Kev ua haujlwm siab: OM5 fiber ntau lub tshuab dhia ua ke tuaj yeem sib txuas luv luv yoj faib ua cov sib txuam sib luag (SWDM) thiab cov tshuab xa hluav taws xob txuas rau yav tom ntej, thiab tsuas yog xav tau 8-core broadband multimode fiber (WBMMF) txhawb 200 / 400G Ethernet daim ntawv thov;
Txo txo ​​tus nqi: OM5 fiber ntau jumper rub tawm ntawm lub koob yoj faib sib faib ntau yam (WDM) thev naus laus zis ntawm hom fiber ntau los txuas ntxiv kom zoo dua nthwv dej wavelength thaum sib xa xov. Nws tuaj yeem txhawb 4 wavelengths ntawm 1-core multimode fiber thiab hloov mus rau qhov yuav tsum tau fiber ntau Cov naj npawb tau raug txo mus rau 1/4 ua ntej, uas zoo heev txo cov nqi txuas ntawm lub network;
Kev sib raug zoo thiab muaj kev sib txuam sib luag: OM5 fiber ntau lub cev muaj peev xwm txhawb nqa cov kev siv ib txwm ua zoo li OM3 cov khoom siv dhia thiab OM4 fiber ntau cov neeg dhia, thiab nws tau haum rau OM3 thiab OM4 fiber dhia thiab muaj peev xwm sib cuam tshuam tau zoo.
