CWDM 4 or 8 Channel Optical Add/Drop MultiplexerCoarse wavelength division multiplexer (CWDM) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provideslow insertion loss,Website:://.zgtech-solution.com, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical pathPerformance SpecificationsParameter 4 channel 8 channel Add Drop Add Drop Operating Wavelength (nm)1471, 1491 or 1470, 1490 etc.Center Wavelength Accuracy (nm)±  0.5Channel Spacing (GHz)20nmChannel Passband (@-0.5dB bandwidth) Min.(nm)≥13Insertion Loss (dB)Add/Drop Ch.≤1.4≤2.5Express Ch.≤0.6≤1.0Channel Ripple (dB)≤0.3≤0.3Isolation @add/drop channel(dB)AdjacentN/A>30N/A>30Non-adjacentN/A>40N/A>40Insertion Loss Temperature Sensitivity (dB/°C )<0.003Wavelength Temperature Shifting (nm/ °C )<0.002Polarization Dependent Loss (dB)<0.10Polarization Mode Dispersion (ps)<0.1Directivity (dB)>50Return Loss (dB)>45Maximum Power Handling (mW)300Operating Temperature (°C)-20 ~ 85Storage Temperature (°C)-40 ~ 85Package Dimension (mm)f1U LGX boxSpecifications may change without noticeOrdering InformationCWDM Configuration 1 Channel Fiber Type Fiber Length Connector  4=4 Ch Add/Drop8=8 Ch Add/Drop471=1471nm491=1491nm1=250um bare fiber2=900um loose tube fiber1=1 Meter2=2 Meter0=None1=FC/APC2=FC/PC3=SC/APC4=SC/PC5=ST 6=LC4-Channel OADM (CWDM-OADM4-1= and CWDM-OADM4-2=) The 4-Channel OADM (CWDM-OADM4-1= and CWDM-OADM4-2=) allows you to add/drop four channels (with different wavelengths) into one direction of an optical ring. The other wavelengths are passed through the OADM. The 4-channel OADMs are transparent to the 1300-nm wavelength and includes a 1300-nm/1500-nm filter to mix legacy SONET/SDH/ATM ring installations with CWDM installations on the same optical fiber. Dual fiber is used for both the network and the GBIC or SFP connections. The two 4-channel OADMs, shown in Figure 2 and Figure 3, support the following wavelengths: •CWDM-OADM4-1—1470-nm, 1490-nm, 1510-nm, and 1530-nm. •CWDM-OADM4-2—1550-nm, 1570-nm, 1590-nm, and 1610-nm. The 4-channel OADM modules are equipped with a monitor port that allows you to attach a power meter or an optical spectrum analyzer to assist you in monitoring and troubleshooting the network.
