DWDM thiab CWDM feem ntau yog siv thev naus laus zis optic kev sib txuas lus rau ib qho kev sib txuas ntawm qhov muag txawv ntawm cov khoom siv txawv txawv ntawm cov kab sib txawv:
Wavelength sij hawm:CWDM, wavelength sib nrug ntau dua los yog sib npaug rau 20 xyoo los ntawm kev sib tw me me, feem ntau}}}}}}}}}}}}
Nqi:Feem ntau, cov cuab yeej siv thiab cov khoom siv yog pheej yig vim lawv cov khoom siv thiab cov khoom siv tsis sib haum xeeb thiab cov khoom siv tsawg dua.
Nrug deb:DWDM cov tshuab tuaj yeem txuas ntxiv mus txuas ntxiv mus deb los ntawm cov kev sib kis tau, feem ntau yog qhov kev sib kis luv, feem ntau nyob rau hauv ntau ntawm kaum ntawm kilmeters .
Daim Ntawv Thov Qhia:DWDM, vim nws cov nthwv dej siab rov qab siv cov yam ntxwv sib txuas lus thiab ua kom muaj kev sib txuas lus tsawg dua thiab ua tiav rau cov chaw taws teeb thiab cov kev kub ntxhov rau hauv nroog thiab kev kub ntxhov
