1 Or 2 Channel Optical Add Dro

CWDM 1,Website:http://www.zgtech-solution.com, 2 Channel Optical Add/dro 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, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical pathPerformance SpecificationsParameter 1 channel 2 channel Add dro Add dro Operating Wavelength (nm)1471, 1491 or 1470, 1490 etc.Center Wavelength Accuracy (nm)± 0.5Channel Spacing (GHz)20nmChannel Passband (@-0.5dB bandwidth) Min.(nm)≥15Insertion Loss (dB)Add/dro Ch.≤0.6≤1.2Express Ch.≤0.8≤1.6Channel Ripple (dB)≤0.3≤0.3Isolation @add/dro channel(dB)AdjacentN/A>30N/A>30Non-adjacentN/A>40N/A>40Express Channel Isolation (dB)≧13Insertion Loss Temperature Sensitivity (dB/°C )<0.005Wavelength 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)f L100 x W80 x H10Specifications may change without noticeBlock Diagram of the One-Channel OADMBlock Diagram of the Two-Channel OADMOrdering InformationCWDM Configuration 1st Operating Wavelength 2nd Operating Wavelength    (for 2CH) Fiber Type Fiber Length Connector  1=1 Ch Add/Drop2=2 Ch Add/Drop27=1270nm 29=1290nm ……47=1470nm49=1490nm  … 16=1610nm27=1270nm 29=1290nm ……47=1470nm  49=1490nm  …  16=1610nm1=250um Bare Fiber2=900um Loose tube Fiber1=1 Meter2=2 Meter0=None1=FC/APC2=FC/PC3=SC/APC4=SC/PC5=ST 6=LC
