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
