CWDM versus DWDM: A Comparison of Technologies | CWDM and DWDM: An In-Depth Examination
In the realm of optical communications, CWDM or DWDM technologies play a crucial role in transmitting vast amounts of data over long distances. Both acronyms stand for wavelength division multiplexing, but they differ significantly in their implementation and capabilities. CWDM leverages a coarse grid of wavelengths, typically spaced 20 nm apart, a
