Kev sib ntaus sib tua ntawm CWDM thiab DWDM: uas yog phooj ywg rau MAN?
Raws li paub rau txhua tus, CWDM thiab DWMD muaj kev cuam tshuam zoo, ob qho tib si kev siv WDM thev naus laus zis thiab tuaj yeem sib kis ntau cov xov hluav taws xob ntev ntev hauv ib qho fiber ntau. Txawm li cas los xij, CWDM haum rau kev sib kis tau luv luv, thaum DWDM haum rau kev sib kis tau ntev. Tsis tas li ntawd, nws kuj tseem muaj qhov sib txawv ntawm kev siv hluav taws xob thiab nqi.
Kev siv fais fab
Feem ntau, txawm tias CWDM system lossis DWDM system, siv cov khoom siv sib xyaw ua ke, qhov kev siv fais fab ntawm lub zog sib txawv qhov sib txawv ntawm cov khoom tseem ceeb ntawm lub teeb module, thiab CWDM module lub zog noj feem ntau yog qis dua lub teeb DWDM optical module lub zog noj, xws li optics CWDM Wan Zhao lub teeb module siv hluav taws xob ntau yog 1.2W, thiab DWDM Wan Zhao lub teeb module hauv 0 ~ 70 ℃ nyob rau hauv qhov kub ua haujlwm ntawm qhov siab tshaj plaws kev siv fais fab yog 1.5W, hauv -40 ~ 85 ℃ nyob rau hauv kev ua haujlwm kub ntawm qhov siab tshaj plaws lub zog noj yog 1.8W, yog li CWDM system lub zog siv qis dua DWDM system lub zog siv.
Tus nqi
Cov nqi sib txawv ntawm CWDM thiab DWDM systems feem ntau yog pom ntawm cov nqi kho vajtse thiab kev siv nyiaj.
Nrog rau qhov nce ntawm tag nrho cov xov tooj ntawm lub ntsej muag wavelength thiab qhov nce ntawm ib qho channel kis tus nqi, kev siv fais fab yuav dhau los ua ib qho tseem ceeb hauv pawg thawj coj saib kev tsim qauv ntawm lub system. Piv nrog DWDM system, CWDM system tsis muaj cov tub yees siv hluav taws xob muaj lub zog siv qis thiab tuaj yeem txuag nqi.
Txawm hais tias DWDM thiab CWDM siv DFB laser ua lub teeb ci, tab sis DWDM txhawm rau tiv thaiv nthwv dej los ntawm kev hloov qhov kub thiab txias mus rau lub lim channel multiplexer thiab demultiplexer, xav siv lub tshuab cua txias (uas yog, lub zog txias) kom tswj tau qhov kub hloov thiab ruaj khov wavelength, qee zaum, tseem tuaj yeem siv lub ntsuas phoo wavelength kom ntseeg tau qhov tseeb ntawm wavelength thiab ruaj khov, thiab CWDM tsis xav tau txias, xws li wavelength locking thev naus laus zis, zoo heev txo tus nqi ntawm cov khoom siv, qhov tam sim no CWDM tus nqi feem ntau tsuas yog 30% ntawm tus nqi ntawm DWDM system.
Los ntawm kev paub saum toj no, CWDM thev naus laus zis thiab DWDM thev naus laus zis muaj tib lub hauv paus ntsiab lus, txheeb ze rau tom kawg thiab yav dhau los muaj qhov zoo ntawm cov nqi qis, kev siv hluav taws xob tsawg, thiab lwm yam. Vim li ntawd, CWDM thev naus laus zis kev tsim kho hauv nroog thaj chaw lossis network muaj peev xwm. yog ib qho kev ua tau zoo tshaj plaws thiab kev xaiv kev lag luam zoo tshaj plaws yuav txo tau tus nqi network, yoog rau kev txhim kho thiab nce ntxiv ntawm kev lag luam, daws qhov teeb meem ntawm qhov sib piv ntawm kev nthuav dav thiab thaj chaw thaj chaw tsim kho.
HTF yog raws tus niaj hnub no, saib mus rau yav tom ntej
Nrog rau kev nce ntxiv ntawm cov ntaub ntawv sib txuas lus hauv lub network thiab qhov muaj peev xwm nce ntxiv ntawm kev sib txuas lus kho qhov muag, CWDM thev naus laus zis yuav dhau los ua qhov kev daws teeb meem zoo rau MAN kev tsim kho vim nws tus nqi qis, kev hloov kho yooj yim thiab ntau hom kev pabcuam. HTF raws li cov kev lag luam uas xav tau tam sim no thiab cov kev xav tau rau kev tsim kho lub network yav tom ntej, tsim tawm ib qho kev sib txuas lus kho qhov muag xaib, nrog rau CWDM coarse wavelength faib multiplex, CWDM coarse sparkling points multiplexer, CWDM optical module (xws li, CWDM SFP, CWDM SFP + ), thiab lwm yam, tuaj yeem muab kev ntseeg tau rau cov kev khiav dej num, yoog raws, ua tau zoo thiab txo tus nqi ntawm cov tshuaj.
