Yuav ua li cas rau nruab Koj lub CWDM MUX DEMUX System?
Coarse wavelength division multiplexing (CWDM) cuab yeej tsim tawm los tsim kom muaj peev xwm ntawm lub xov tooj cua fiber ntau tsis tau ntxiv fiber ntau. Hauv CWDM, CWDM MUX DEMUX (multiplexer / demultiplexer) yog qhov tseem ceeb tshaj plaws. Feem ntau, CWDM MUX DEMUX yog siv los ua kom muaj cov kabmob fiber ntau tam sim no los ntawm kev xa ntau hom kabmob, feem ntau yog txog 18 cais kev tshaj li ib tus fiber ntau. Tsab xov xwm no feem ntau yuav piav qhia koj nruab CWDM MUX DEMUX system. Yog tias koj yog ib tus neeg siv kev paub, peb xav kom koj ua raws li cov ncauj lus kom ntxaws txog cov lus qhia nyob hauv seem ntawm cov tshooj no.
CWDM MUX DEMUX Module Overview
CWDM MUX DEMUX module yog lub cuab yeej ua ke, kev siv tau zoo heev thiab yooj yim siv. Cov khoom siv no muaj nyob nrog ntau lub wavelength ua ke, feem ntau ntawm 1270nm rau 1610nm (20nm nras). Raws li cov ntawv thov sib txawv, ib lub CWDM MUX DEMUX module tau tsim los ua ntau txoj hauv kev. Ib txoj kab 4 yuav tau siv MUX DEMUX module los siv rau plaub hom wavelengths mus rau ib qho fiber ntau (hauv daim duab hauv qab). Qhov no tso cai rau koj mus ib txhij kis plaub hom ntaub ntawv tshaj tib tus fiber ntau. Yog tias koj siv lub CWDM multiplexer thaum pib ntawm koj qhov network, koj yuav tsum siv CWDM demultiplexer rau ntawm qhov kawg kom sib cais los sis txo cov kab txuas rau qhov chaw khiav dej num kom cia lawv mus rau cov neeg tau txais kev pab. Feem ntau, CWDM MUX DEMUX yog ib qho qauv uas siv tau los ua ib qho kev sib txuas los yog kev sib tw ntawm ob tog ntawm kab xov fiber ntau. Txawm li cas los xij, nws tseem yuav tsum tau muab siv ua ob tog.
CWDM MUX DEMUX System Txheej Txheem Tshooj
Ib qho yooj yim CWDM MUX DEMUX system muaj ib chav ua haujlwm hauv zos, CWDM MUX DEMUX module thiab ib chav chaw nyob. Feem ntau Ib Cheeb Tsam Hauv Nroog los yog Chaw Teeb Yeem raug xa mus rau ob qhov sib txawv. Feem ntau, txhawm rau nruab ib lub CWDM MUX DEMUX module, lub chassis yuav tsum muab ntsia ua ntej los tuav tus qauv. Dhau li, kom txuas mus rau CWDM MUX DEMUX module rau qhov hloov, peb yuav tsum nruab CWDM SFP rau kev hloov ntawm cov tes hloov ua ntej. Tom qab ntawd siv cov kabmob ua daim npav xa xov mus txuas rau cov kev sib txuas lus mus rau CWDM MUX DEMUX module. Yog li, thaum peb xav tsim kom muaj lub CWDM MUX DEMUX system, cov khoom peb yuav tsum tau muaj xws li khib-mount chassis, CWDM MUX DEMUX module, CWDM SFP transceiver thiab cov kabmob singlemode.
CWDM MUX DEMUX System Installation Steps
Txhim kho lub CWDM MUX DEMUX system, muaj plaub theem pib ua haujlwm:
Nruab cov Rack-Mount Chassis
CWDM khib nyiab chassis tuaj yeem txuas rau hauv tus txheej txheem 19-inch ntu lossis khib. Thaum muab cov chassis los sib txuas rau tus khib tsho uas muaj 19-inch, xyuas kom meej tias koj nruab ib lub khib nyiab chassis hauv tib lub khib los yog khib uas nyob ze koj lub zog kom koj txuas tau tag nrho cov cables ntawm koj CWDM MUX DEMUX modules thiab CWDM SFP qhov kev hloov ntawm koj lub cev.
Nruab rau CWDM MUX DEMUX Modules
Yog xav muab ib lub module, koj yuav tsum dlhos lub module nrog lub chassis txee (qhia hauv daim duab hauv qab) ua ntej thiab maj mam thawb lub hau rau hauv rab txeej kab noj hniav. Thaum kawg, nteg cov ntes raug kaw.
Txuas lub CWDM MUX DEMUX hloov
Tom qab muab tus CWDM SFP transceiver rau hauv qhov kev hloov, ces peb yuav tsum siv lub xov tooj singlemode thaj txuas mus rau qhov kev xa mus rau CWDM MUX DEMUX.
Thov nco ntsoov tias CWDM MUX DEMUX khub yuav tsum nqa cov kev sib tw nrog tib lub wavelength. Vim tias txhua lub transceiver yuav ua haujlwm ntawm qhov chaw nres nkoj uas tsim nyog thiab cov ntaub ntawv yuav tas li ntawm cov khoom siv nrog tib lub wavelengths. CWDM SFP kev hloov siab nrog txawv wavelength tej zaum yuav muaj xim txawv xim. Siv CWDM SFP transceiver xim cov qauv uas muaj hauv daim duab hauv qab no los pab koj txuas tus CWDM MUX DEMUX rau koj lub cev.
Txuas CWDM MUX DEMUX Pairs
Thaum koj siv lub CWDM multiplexer kawg ntawm koj cov tes hauj lwm, koj yuav tsum siv lub demultiplexer rau lwm qhov kawg ntawm lub network. Vim li no, lub kauj ruam kawg ua kom tiav CWDM MUX DEMUX yog mus txuas rau MUX DEMUX haujlwm (lossis multiplexer thiab demultiplexer). Rau duplex MUX DEMUX, yuav tsum tau siv ob kab ntawm singlemode lub thaj ua haujlwm. Rau simplex MUX DEMUX, tsuas yog ib lub xov tooj singlemode thaj xwb txaus. Tom qab tag nrho, koj lub CWDM MUX DEMUX system ces tau ntse tiav.
Xaus
Hauv cov ntsiab lus, MUX DEMUX system yog ib qho txiaj ntsig zoo tsim nyog uas yog ib qho yooj yim rau nruab. CWDM MUX DEMUX, CWDM multiplexer nkaus xwb, thiab CWDM demultiplexer nkaus xwb yog muaj kev ywj pheej, pheej yig cov nqi uas tsim kom muaj cov kabmob muaj fiber ntau thiab cia cov neeg ua haujlwm kom siv cov khoom siv fiber ntau hauv zos lub voj voog thiab cov tuam txhab lag luam. FOCC CWDM MUX DEMUX yog ib qho khoom siv dav dav dav dav dav ntawm CLEDM (1270 ~ 1610nm) mus txog 18 raws (2, 4, 5, 8, 9, 16, 18 raws li muaj) los yog kho qhov muag ntsaws rau ib tus khub fiber ntau . Ua ke nrog peb cov CWDM kev sib txuas lus los yog cov pauv hloov lub wavelength, cov ntaub qhwv lub fiber ntau yuav siv tau rau txoj kev siv nyiaj tsawg.
