CWDM (Coarse Wavelength Division Multiplexer) yog tus nqi qis WDM kev siv thev naus laus zis rau cov cheeb tsam hauv cheeb tsam network nkag mus txheej. Hauv txoj ntsiab cai, CWDM siv cov khoos phis tawj sib txuas mus rau ntau qhov kho qhov muag teeb liab ntawm cov nthwv dej sib txawv mus rau ib qho fiber ntau rau kev sib kis. Thaum tau txais qhov kawg ntawm qhov txuas, cov teeb liab sib xyaw hauv cov fiber ntau tau decomposed rau hauv cov yoj sib txawv sib txawv nrog kev pab ntawm cov kho qhov muag demultiplexer Teeb liab rau qhov tsim nyog tau txais lub cuab yeej.

Qhov sib txawv ntawm CWDM thiab DWDM:
1. CWDM muaj 18 pawg, los ntawm 1270nm txog 1610nm, thiab lub sijhawm nruab nrab ntawm txhua pawg yog 20nm. Muaj peb hom kev sib txawv ntawm channel rau DWDM raws li xav tau: 0.4nm (50Ghz), 0.8nm (100Ghz) thiab 1.6nm (200Ghz), 100GHz (los ntawm C17 txog C61, uas yog siv feem ntau, haum rau cov cuab yeej siv tau); C17 txog H61, haum rau cov cuab yeej siv high-channel).
2, .CWDM wavelength 1470nm ~ 1610nm feem ntau siv DFB lasers, vim tias qhov sib nrug ntawm channel yog loj, yog li CWDM cov cuab yeej thiab lasers pheej yig dua li DWDM cov cuab yeej.
3.CWDM kho qhov muag yoj channel qhov sib nrug yog dav, tus naj npawb ntawm qhov sib txawv ntawm qhov kho qhov muag wavelengths ntawm tib lub fiber ntau dua DWDM, qhov laj thawj rau" ntxhib" thiab" ntom" lub npe;
4.CWDM kho qhov muag kho qhov muag siv lub tshuab ua kom txias tsis zoo, uas tau hloov kho tshuab hluav taws xob; DWDM siv lub tshuab txias txias txias, uas ntsuas nrog qhov kub thiab txias.
5. Vim tias qhov kub tsis sib xws nyob rau ntau qhov ntawm lub teeb nthwv dej, kev ntsuas kub yog qhov nyuaj thiab raug nqi ntau. CWDM zam qhov kev nyuaj no, yog li txo tus nqi ntau heev. Tam sim no, tus nqi ntawm CWDM system feem ntau tsuas yog 30% ntawm DWDM;
6.CWDM qhov kev siv hluav taws xob thiab lub cev me me me dua DWDM system.
