TusDyog hais tiasBEtween CWDMANd DWDM
CWDM thiab DWDM yog qhov tseem ceeb kho qhov kev sib txuas lus thev naus laus zis rau kev nthuav dav thiab deb, lawv muaj qhov sib txawv txawv rau ntau yam kev siv.
1. wavelength plav thiab kev paub tseeb
Qhov kev txawj ntse tshaj plaws ntawm CWDM thiab DWDM yog wavelength pluction {} Tus kws nqa khoom nyob ib puag ncig ntawm DWDM yog qhov nqaim heev, txhua band yuav yuav tsum tsuas yog 0 {{{{}} 2nm, 0 {}}} 4nm, uas ua rau rov siv dua tshiab rau 80 mus rau 160 wavelength. No "kev sibntsuam" thiab "kev thov siv ntom ntom" yog los ntawm qhov no.
Nyob rau hauv cov nqe lus ntawm kev paub tseeb, CWDM siv Uncooled uncided {} lub cav txias ua tiav, tus nqi ntawm DWDM yog ntau dua Cwdm .
{{0 {}} Daim Ntawv Thov Kev Tso Cai thiab Tus Nqi
CWDM thiab DWDM kuj txawv tseem ceeb ntawm kev thov cov xwm txheej, xws li siv tau dav dav, tsim qauv xov tooj tau dav, uas tuaj yeem txuag cov neeg siv khoom siv nqi .
DWDM yog qhov tsim nyog dua rau kev ncua ntev, loj-muaj peev xwm ua tiav cov ntaub ntawv loj hlob ua kom tiav, DWDM Kev Ua Haujlwm Loj Kev lag luam .
3.} cov yam ntxwv ntawm kev txhim kho thiab kev txhim kho cov kev cia siab
CWDM thiab DWDM txhua tus muaj cov yam ntxwv tshwj xeeb thiab kev tsim kho kom tau muaj kev txhawj xeeb ntau ntxiv rau yav tom ntej hauv lub neej yav tom ntej.
DWDM thev naus laus zis yog qhov zoo ntawm cov khoom muaj peev xwm loj, cov ntaub ntawv tseem ceeb thiab kev sib txuas lus hauv internet ntxiv rau yav tom ntej kev sib txuas lus network {}}
Hauv cov ntsiab lus, CWDM thiab DWDM, qhov tseem ceeb wavelength {{{1} {{1} . Kev daws .
