Daim ntawv thov CWDM thev naus laus zis hauv kev sib tham hauv xov tooj yog paub tab heev. International Telecommunication Union txhais 18 CWDM raws nrog 20 nm luv hauv 1271-1611 nm band. CWDM4 tus qauv hauv kev sib txuas lus cov ntaub ntawv tau txais plaub lub wavelengths, uas yog 1271-1331 nm, uas ze rau qhov xoom tawg ntawm G652 ib hom fiber ntau. Data Center 100G Optical transceiver module, daim ntawv ntim khoom tseem ceeb tam sim no yog QSFP28, sib xyaw ua ke 4 lub tshuab ua hluav taws xob ib leeg, siv lub tshuab ntsuas qhov muag pom thiab nws cov tsav tsheb sib txuas, nrog rau CWDM4 cov khoom tsis siv. Txhawm rau koom ua ke CWDM4 tivthaiv rau hauv QSFP28 tus qauv, nws yog qhov tsim nyog los tsim tus qauv me me li sai tau, thiab qhov yuav tsum tau ua yog nruj dua li CCWDM module (compact CWDM module) hauv kev thov xov tooj.
