Mini size Coarse Wavelength Division Multiplexers(Mini CWDM,Website: , MCWDM), are integrated optical modules using our proprietary optical bench platform which can significantly improve optical performance, while also reduce manufacturing costs. Compare to the common standard CWDM module, Flyin's Mini CWDM takes much smaller package size. Much space can be saved in the application and meanwhile the performance and parameters are much better. All Flyin's CWDM modules are Telcordia qualified.(Meet TELCORDIA GR-1221-CORE)Features• Mini Size• High Reliability• Low Insertion Loss  and Better Uniformity• Ultra High Thermal  Stability• Epoxy-Free in Optical  Path• RoHS CompliantApplications• RoHS Compliant• CATV System• Network upgradingSpecificationParameterValuesChannel Number488+E18+E2Central    Wavelength (nm)1270, 1290…1610 or 1271, 1291…1611Channel Spacing    (nm)20Passband (nm)Channels+/-6.5Upgrade port1310+/-501260~1457Isolation (dB)Adjacent Channel>30Non-adjacent    Channel>40Upgrade port>15Insertion Loss (dB)Channels1.01.51.61.8Upgrade port1.21.2Channel Ripple (dB)<0.3Fiber TypeCorning SMF-28 with 900mm loose tubePolarization    Dependent Loss (dB)<0.15Polarization    Mode Dispersion (ps)<0.1Directivity (dB)>50Return Loss (dB)>45Maximum Power    Handling (mW)500Operating    Temperature (℃)-5 ~ +70Storage    Temperature (℃)-40 ~ +85Package    Dimension (mm)P1: L44 x W25 x H6 P2: L53.8 x W28 x H8P3: L54 x W32 x H7.4Note:1.
