Coarse Wavelength Division Multiplexing (CWDM) yog kev siv cov Fiber Optical Multiplexer kom sib txawv wavelengths ntawm lub teeb liab multiplexed mus rau ib qho kho qhov muag fiber ntau rau kis, ntawm qhov tau txais qhov kawg ntawm qhov txuas, nrog rau Fiber Optical Multiplexer fiber sib xyaw cov teeb liab yog decomposed rau hauv kev sib txawv wavelengths teeb liab, txuas nrog rau cov cuam tshuam tau txais cov tshuab.
100GHz CWDM Mux / Demux Module hla dhau ib qho lossis duplex ib hom fiber ntau yog qhov muaj ntau los txuas koj qhov bandwidth tag nrho. Nws muab cov stability siab thiab kev ntseeg tau, thiab muaj cov pob me me. Nws ua haujlwm wavelength yog los ntawm 1270nm txog 1610nm (1261nm-1611nm) uas tau muab tag nrho 18 raws nrog 20nm channel spacing.
