The wavelength spacing in coarse wavelength division multiplexing is typically nm
The wavelengths are spaced out by 20 nanometers which allows up to 18 channels to be accommodated within the 1270 nm to 1610 nm spectrums. This spacing is beneficial because CWDM can be less expensive than utilizing other spacing lasers due to the reduced inter-channel interference. CWDM was standardized by the ITU-T G. It can carry up to 18 CWDM wavelengths over one pair of fibers. The channels are combined and transmitted over a single fibre optic cable.

Diffraction Grating Principle Wavelength Division Multiplexing
A diffraction grating is a surface with a large number of parallel, equally spaced grooves or slits. When light hits the grating, each groove acts as a source of diffracted waves. These waves interfere with each other, producing sharp bright lines (maxima) at angles that depend. In optics, a diffraction grating is a grating with a periodic structure of appropriate scale so as to diffract light, or another type of electromagnetic radiation, into several beams traveling in different directions (i. The emerging. The advent of Dense Wavelength Division Multiplexing (DWDM) has fundamentally changed the economics of core optical networks. What makes them particularly useful is the fact that they form a sharper pattern than double slits do. Where a double slit gives you broad, fuzzy fringes, a grating with thousands of slits produces sharp, well-separated maxima that let you measure wavelengths with.
