Dab tsi yogTnwsDifferenceBetweenACoarseWawvDkev ntsuas ntsuasMultiplexer (CWDM)AndADyaumWawvDkev ntsuas ntsuasMultiplexer (DWDM)?
1. CWDM muaj 18 txoj hlua, txij li 1270nm txog 1610nm, nrog qhov sib nrug li 20nm ntawm txhua qhov qhab. DWDM muaj 3 qhov chaw rau ib qho channel raws li qhov yuav tsum tau ua: 0.4nm (50Ghz), 0.8nm (100Ghz) thiab 1.6nm (200Ghz), 100GHz (los ntawm C17 txog C61, uas yog qhov feem ntau siv rau cov khoom siv rau qhov qub); 50GHz (los ntawm C17 txog H61 rau cov channel siab).
2, CWDM wavelengths 1470nm ~ 1610nm feem ntau siv DFB lasers, vim tias cov kem ntawm qhov dav yog qhov loj, yog li CWDM cov khoom siv thiab cov lasers pheej yig dua DWDM khoom siv.
3, CWDM optical channel spacing yog qhov dav dua, tus naj npawb ntawm multiplexed optical wavelengths ntawm tib lub fiber ntau tsawg dua DWDM, cov laj thawj rau" coarse" thiab" ntom&tuab; cov npe nyob ntawm no;
4. CWDM kev hloov kho lub teeb siv lub ntsej muag tsis ua pa thiab siv hluav taws xob tsis zoo; thaum DWDM siv cov cua txias laser uas tig mus nrog lub ntsuas kub.
5. Vim qhov ntsuas kub thiab txias tsis sib npaug dhau ib qhov dav dua nthwv dej ntom nti, qhov ntsuas qhov kub thiab txias yog qhov nyuaj thiab raug nqi rau kev coj ua. CWDM zam kev nyuaj no thiab yog li tus nqi txo. Tam sim no, tus nqi ntawm CWDM system feem ntau tsuas yog 30% ntawm DWDM;
6. Kev siv hluav taws xob thiab lub cev me me ntawm CWDM system muaj ntau dua me dua li cov DWDM.
OPTICO KEV SIB TXUAS LUS (www.fiberopticom.com) tsom mus rau kev txhim kho offiber optic network sib txuas lus cov khoom kab thiab muab kev daws teeb meem zoo rau cov khoom siv sib txuas fiber ntau. Peb muab cov fiber ntau ua ke, xws li cov hlua fiber ntau, fiber ntau pigtail, PLC splitter, txuas txuas ceev, MTP / MPO, CWDM / DWDM, SFP, FTTH tov, Cov ntaub ntawv nruab nrog cov xov hluav taws xob, thiab lwm yam. kev tsim khoom thiab tshuaj xyuas, kom ntseeg tau tias muaj kev ua haujlwm zoo thiab ruaj khov khoom zoo, thiab kev nyab xeeb thiab kev ntseeg tau zoo kom ntseeg tau siv lub sijhawm ntev ntawm cov khoom.
