Wavelength Division Multiplexing Band
Course wavelength division multiplexing is a technique to allow up to eighteen wavelengths to co-exist on a single optical fibre. These wavelengths are spaced at 20nm centres and are 20nm wide. It is defined as the distance between two successive crests of a wave. Figure 1 shows a single wave and its amplitude and wavelength. Why Is WDM Used? With the exponential growth in communications, caused mainly by the.
