CWDM/DWDMwavelength division multiplexing zida kugwiritsa ntchitoPamene zofunikira za anthu za bandwidth zikukulirakulira, Dense Wavelength Division Multiplexing (Chithunzi cha DWDM) zida zapita patsogolo kwambiri pakuchepetsa ndalama, motero zimakondedwa kwambiri pamsika. Komabe, zida za coarse wavelength division multiplexing (CWDM) akadali ndi phindu lamtengo wapatali pazochitika zomwe maulendo ogwirizanitsa ndi otsika kuposa 10G ndi kufalitsa mtunda waufupi. Pomanga maukonde otsika mtengo wa data, akadali zida zotheka kwambiri pakadali pano.Kutumiza kwa Hybrid kwa CWDM/DWDM wavelength division multiplexing zidaCWDM wavelength division multiplexing zida ndi DWDM wavelength division multiplexing zida ali ndi ubwino wawo mu OTN network. Ubwino wa zida za CWDM wavelength division multiplexing ndikuti zimatha kugwiritsa ntchito ma lasers otsika mtengo omwe amagawidwa omwe safuna kuzizira komanso mitengo yotsika. Zosefera zopanda pake, motero CWDM wavelength division multiplexing equipment system ikugwiritsidwa ntchito kwambiri mu DWDM wavelength division multiplexing equipment system. Ngakhale kuti teknoloji ya CWDM ingagwiritsidwe ntchito mu machitidwe a DWDM kuti agwiritse ntchito ma modules otsika mtengo, CWDM channel spacing ndi yaikulu, kotero kuti chiwerengero cha mafunde omwe amapezeka mu dongosololi chidzachepetsedwa, ndipo izi zimachepetsanso mphamvu yotumizira dongosolo, kotero mu a. kumlingo wina, sichingagwirizane ndi zida zosakanizidwa za DWDM wavelength division multiplexing.
