DWDM (Dense Wavelength Division Multiplexing) MUX thiab demux yog cov khoom tseem ceeb hauv kev sib txuas lus fiber ntau niaj hnub.
DWDM MUX thiab demux yog qhov tseem ceeb rau kev xa cov ntaub ntawv, video thiab suab tsheb hauv kev sib txuas lus niaj hnub. Cov cuab yeej no muab lub peev xwm tsim nyog los ua kom tau raws li qhov xav tau ntau ntxiv rau kev sib txuas lus siab thiab siab bandwidth.
Ib qho txiaj ntsig ntawm DWDM MUX thiab demux yog tias lawv tuaj yeem tswj tau ntau lub cim ntawm ib qho fiber ntau. Qhov no yog ua tiav los ntawm kev siv ntau cov channel, txhua tus nrog nws tus kheej wavelength. Piv txwv li, DWDM MUX tuaj yeem xa mus txog80 channelntawm cov ntaub ntawv ntawm qhov sib txawv wavelength.
Lwm qhov zoo dua ntawm DWDM MUX thiab demux yog tias lawv muaj txiaj ntsig zoo ntawm qhov chaw thiab lub zog siv. Qhov no yog vim lawv muaj peev xwm kis tau thiab tau txais cov cim qhia ntau tshaj ib qho fiber ntau, txo cov kev xav tau ntawm ntau cov fibers thiab cov khoom siv.
DWDM MUX thiab demux kuj tseem txhim khu kev qha thiab ruaj khov. Lawv tau tsim los nrog cov khoom siv zoo thiab cov khoom siv los xyuas kom meej tias lawv tuaj yeem tiv taus ib puag ncig hnyav thiab ua haujlwm zoo rau ntau xyoo.
Hauv cov ntsiab lus, DWDM MUX thiab demux yog cov khoom tseem ceeb hauv kev sib txuas lus fiber ntau niaj hnub. Lawv ua kom muaj ntau lub teeb liab ntawm qhov sib txawv wavelengths kom kis tau thiab tau txais dhau ib qho fiber ntau, txhim kho lub peev xwm thiab kev ua haujlwm ntawm lub network zoo heev. Nrog lawv cov kev ntseeg siab, kev ua tau zoo, thiab muaj peev xwm, DWDM MUX thiab demux yog qhov tseem ceeb ntawm txhua qhov kev sib txuas lus niaj hnub no.
