CWDM/DWDMwavelength division multiplexing khoom sivRaws li tib neeg cov kev xav tau rau bandwidth tau nce siab thiab siab dua, Dense Wavelength Division Multiplexing (DWDM) cov cuab yeej tau ua tiav zoo hauv kev txo cov nqi, thiab yog li ntawd ntau thiab ntau nyiam nyob rau hauv kev ua lag luam. Txawm li cas los xij, coarse wavelength division multiplexing khoom (CWDM) tseem muaj tus nqi siab dua hauv cov xwm txheej uas cov nqi sib txuas qis dua 10G thiab kev sib kis luv luv. Hauv kev tsim kho network ntawm cov ntaub ntawv qis, nws tseem yog cov cuab yeej siv tau tshaj plaws tam sim no.Hybrid kis ntawm CWDM / DWDM wavelength division multiplexing khoomCWDM wavelength division multiplexing khoom thiab DWDM wavelength division multiplexing khoom muaj lawv tus kheej zoo hauv OTN tes hauj lwm. Qhov zoo ntawm CWDM wavelength division multiplexing cov cuab yeej yog tias nws tuaj yeem siv tus nqi qis tshaj tawm cov lus qhia lasers uas tsis tas yuav ua kom txias thiab tus nqi qis. Cov lim dej tsis zoo, yog li CWDM wavelength division multiplexing equipment system yog tam sim no siv dav hauv DWDM wavelength division multiplexing equipment system. Txawm hais tias CWDM thev naus laus zis tuaj yeem siv rau hauv DWDM cov tshuab siv cov khoom siv kho qhov muag pheej yig dua, CWDM channel qhov sib nrug yog qhov loj, yog li tus naj npawb ntawm cov wavelengths muaj nyob rau hauv lub kaw lus yuav raug txo, thiab qhov no kuj txwv qhov kev sib kis ntawm lub cev, yog li hauv ib qho Qee qhov ntawm qee qhov, nws tseem tsis tuaj yeem khaws nrog cov khoom siv tsis yog DWDM wavelength division multiplexing.
