What are CWDM and DWDM ?
Wavelength-division multiplexing (WDM) is a process in which multiple optical carrier signals are combined into one signal (Multiplexing), on the same physical fibre optic cable using several wavelengths with each carrying different data. Coarse Wavelength-division multiplexing (CWDM) and Dense Wavelength-division multiplexing (DWDM) are variants of this technology.
CWDM generally offer 8 different wavelengths, each separated by 20 nm, between 1470nm and 1630 nm. In contrast DWDM can have up to 144 different wavelengths, often with only 2 nm spacing, over equivalent wavelengths to CWDM optics. The main advantage of both CWDM and DWDM is that they allow you to expand your networks capacity without the need for physical fibre optic cabling.
