DWDM Expansion over CWDM

With 18 total wavelengths available, CWDM is popular and a good start for most customers due to its relatively low cost and high increase in capacity versus a single data stream. However, as bandwidth demands increase, it becomes necessary for those same customers to add additional capacity. DWDM allows you to add this additional capacity without replacing your existing CWDM infrastructure and with minimal—if any—service interruption.
