Sopofiber offers a full range of CWDM Mux-Demux and Optical Add Drop Multiplexer (OADM) units to suit all kinds applications and network solutions. Some most common ones are: Gigabit & 10G Ethernet,Website: , SDH/SONET, ATM, ESCON, Fibre Channel, FTTx and CATV.Sopofiber’s Coarse wavelength division multiplexer (CWDM Mux/Demux) utilizes thin film coating technology and proprietary design of non-flux metal bonding micro optics packaging. It provides low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path.Our CWDM Mux Demux products provide up to 16-channel or even 18-channel Multiplexing on a single fiber. Due the the low insertion loss is needed in WDM networks, we can also add "Skip Component" in a CWDM Mux/Demux module to reduce the IL as an option. Standard CWDM Mux/Demux package type include: ABS box package, LGX pakcage and 19" 1U rackmount.Features• Low Insertion Loss• Wide pass band• High Channel Isolation• High Stability and reliability• Epoxy-free on Optical Path• Access NetworkApplications• Line Monitoring• WDM Network• Telecommunication• Cellular Application• Fiber Optical amplifier• Acess NetworkPerformance Specifications for 8+1-CH CWDM ModuleParameters8+1-CH    Mux8+1-CH    DemuxChannel    Wavelength (nm)1270-1610 or    1271-1611Center    Wavelength Accuracy (nm)± 0.05Channel    Spacing (GHz)20nmChannel    Passband (@-0.5dB bandwidth (nm)± 7.5 / ± 6.5Insertion    Loss (dB) (Without skip component)≦ 2.8Insertion    Loss (dB) (With skip component)≦ 2.0Channel    Uniformity (dB)≦ 0.6Channel    Ripple (dB)≦ 0.3Isolation    (dB)Adjacent≧30Non-adjacent≧40Express Port≧12Insertion    Loss Temperature Sensitivity (dB/°C )≦ 0.005Wavelength    Temperature Shifting (nm/ °C )≦ 0.002Polarization    Dependent Loss (dB)≦ 0.1Polarization    Mode Dispersion (ps)≦ 0.1Return    Loss (dB)≧50Directivity≧45Max Power    Handling (mW)300Operating    Temperature (°C)-40 ~ +85Storage    Temperature (°C)-40 ~ +85Package    Dimension (mm)L100 X W80 X 10Note: All parameters are for device without connectors.Ordering InformationCWDMXXXXXXXXX Channel    SpacingNumber of    ChannelsConfiguration1st    ChannelFiber    TypeFiber    LengthIn/Out    ConnectorC=CWDM    Grid04=4-CH08=8-CH16=16-CH18=18-CHN=N-CHM=MuxD=Demux27=1270/1271nm……47=1470/1471nm49=1490/1491nm……61=1610/1611nmSS=special1=Bare    fiber2=900um    loose tube3=2mm    Cable4=3mm    Cable1=1m2=2mS=Specify0=None1=FC/APC2=FC/PC3=SC/APC4=SC/PC5=ST6=LCS=Specify
