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 ' 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 SpecificationsParameter4 Channel8 Channel16 ChannelMuxDemuxMuxDemuxMuxDemuxChannel    Wavelength (nm)1270~1610Center    wavelength Accuracy (nm)±0.5Channel Spacing    (nm)20Channel Passband    (@-0.5dB bandwidth (nm)>13Insertion Loss    (dB)≤1.6≤2.5≤4.5Channel Uniformity    (dB)≤0.6≤1.0≤1.5Channel     Ripple (dB)0.3Isolation (dB)AdjacentN/A>30N/A>30N/A>30Non-adjacentN/A>40N/A>40N/A>40Inertion Loss    Temperature Sensitivity (dB/℃)<0.005Wavelength    Temperature Shifting (nm/℃)<0.002Polarization    Dependent Loss (dB)<0.1Polarization    Mode Dispersion<0.1Directivity (dB)>50Return    Loss （dB）>45Maximum Power    Handling (mW)300Opterating    Temperature (℃)-5~+75Storage    Temperature (℃)-40~85Package    dimension (mm)L100 x W80 x H10L142 x W102 x H14.5Specification may change without notice.Above specification are for device without connector.Ordering InformationCWDMXXXXXXXXXX Channel SpacingNumber of ChannelsConfiguration1st ChannelFiber TypeFiber LengthIn/Out Connector C=CWDM Grid 04=4 Channel08=8 Channel16=16 Channel18=18 ChannelN=N Channel M=MuxD=DemuxO=OADM 27=1270nm……47=1470nm49=1490nm……61=1610nmSS=special 1=Bare fiber2=900um loose tube3=2mmCable4=3mmCable 1=1m2=2mS=Specify 0=None1=FC/APC2=FC/PC3=SC/APC4=SC/PC5=ST6=LCS=Specify
