CWDM & DWDM combined transmission solution


Why CWDM & DWDM combination network can be achieved

The CWDM wavelength range is 1270-1610 nm and the channel spacing is 20 nm, virtually covering all ranges of DWDM wavelengths, whereas DWDM wavelength channel spacing is much smaller (0.4 nm / 0.8 nm). So CWDM wavelengths near DWDM wavelengths can be used to transmit DWDM wavelength.In most practical applications, CWDM 1530nm and 1550nm channels are used to achieve CWDM & DWDM combined transmission. 


The advantages of CWDM & DWDM combined optical transmission

Reduce costs & investment protection 

Add DWDM wavelengths to CWDM systems to increase capacity and maximize return on investment 

Pay-as-you-grow Feature

Easily scale CWDM solutions to 44 wavelengths without impacting network traffic 

Easy to install and maintain 

Installed in the FMU 2-slot 1U chassis, facilitates cable management and network operation
