Kev faib tawm
Raws li cov ntawv ntim khoom sib txawv, WDM tuaj yeem muab faib ua xenpak WDM, X2 WDM, GBIC WDM, XFP WDM, SFP WDM thiab SFP + WDM.
Raws li qhov sib txawv ntawm lub koob yob sib txawv, WDM tuaj yeem muab faib ua (coarse wavelength division multiplexing) CWDM optical module thiab (nthwv dej wavelength faib multiplexing) DWDM optical module; CWDM optical module adopts coarse wavelength division multiplexing (CWDM) thev naus laus zis, uas tsim nyog rau kev sib kis luv luv. Feem ntau, hauv Gigabit Ethernet thiab taw tes sib txuas network, DWDM optical module txais txoj kev ntom ntom ntuag sib faib ntau yam sib txawv (DWDM) thev naus laus zis, uas tsim nyog rau kev sib kis ntev ntev Nws yog siv rau hauv tus txiv neej thiab LAN.
Qhov sib txawv ntawm WDM thiab cov qauv kho qhov muag
Lub WDM yog qhov ntsuas qhov ntsuas siab dhau. Qhov hluav taws xob kho qhov muag tsis tawm laser. Feem ntau, kho qhov muag dav hlau waveguide thev naus laus zis yog siv los faib cov nqaj ntawm lub teeb rau hauv ntau nqaj, thaum qhov ntsuas kho qhov muag tsis zoo ib yam ntawm tus nquag kho qhov muag. Txhua qhov module muaj ob qho chaw nres nkoj, ib qho xa tawm thiab ib lub txais, thiab lub ntsuas cua siv lub tshuab laser. Ntxiv rau, WDM thev naus laus zis siv hauv WDM, uas tuaj yeem txuag cov nqi ntawm qhov kho qhov muag, tab sis cov qauv kho qhov muag tsis zoo ib yam.
Kev xaiv ntawm wavelength faib module
Kev xa khoom tus nqi, kev sib kis deb thiab tus nqi yuav tsum raug txiav txim siab thaum xaiv WDM.
1. Kev sib kis nqi: raws li qhov xav tau ntawm network bandwidth, xaiv cov pob tsim nyog ntawm WDM, piv txwv li, hauv Gigabit Ethernet, xaiv SFP WDM; rau 10G Ethernet, xaiv SFP + WDM, thiab lwm yam;
2. Kev sib kis deb: yog tias nws siv nyob rau hauv cov network loj ib puag ncig nrog kev sib kis ntev, DWDM optical module yuav tsum tau xaiv;
Yog tias CWDM tsis raug xam tias, tus nqi ntawm qhov kho qhov muag kis tau ntev yog ntev.
