There are 18 center wavelengths available from 1270 nm to 1610 nm, with each step 20 nm. Maximum optical budget is 23dB . The transceiver consists of two sections: The transmitter section consists of a directly modulated uncooled CWDM DFB/EML laser, driver and signal conditioner. The receiver section incorporates a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and signal conditioner or APD.Features:• Supports 10G speed rate• Hot-Pluggable X2 Footprint Compliant with X2 MSA• 18-Wavelengths CWDM DFB/EML Transmitter from 1270nm to1610nm,with Step 20nm• Low Power Consumption• Maximum distance is 80km• Duplex SC Connector• Case Operation Temperature Range -5°C to 70°C• Digital Diagnostic Monitoring/DOM• RoHS, CE, FDA, FCC, TUV, UL certificatesPackagePart No.Fiber TypeData Rate RangeWavelengthOptical ComponentsDistance Range/Power BudgetConnectorCase Temperature rangeDDMApplicationFunctionX2ZDAH109-DCLxxSMF9.95~11.1GCWDM 1270/1290/1310/1330nmDFB/PIN10dBLC0~70DEthernet,10GFCX2ZDAH109-DCLxxSMF9.95~11.1GCWDM 1470~1610nmDFB/PIN10dBLC0~70DEthernet,10GFCX2ZDAH149-DCLxxSMF9.95~11.1GCWDM 1270/1290/1310/1330nmDFB/PIN14dBLC0~70DEthernet,10GFCX2ZDAH149-DCLxxSMF9.95~11.1GCWDM 1470~1610nmEML/PIN14dBLC0~70DEthernet,10GFCX2ZDAI239-DCLxxSMF9.95~11.1GCWDM 1270/1290/1310/1330nmDFB/APD23dBLC0~70DEthernet,10GFCX2ZDAI239-DCLxxSMF9.95~11.1GCWDM 1470~1610nmEML/PIN23dBLC0~70DEthernet,10GFC
