This chapter is an introduction of the Wavelength-division multiplexing (WDM) technologies (such as Dense WDM and coarse WDM) and their recent applications in optical networks. WDM is used to multiplex multiple optical carrier signals on a single optical fibre by using different wavelengths of laser light to carry different signals. This allows for a multiplication in available bandwidth and, in addition, makes possible to perform bidirectional communications over one strand of fibre. We present the optical components used in WDM and review some of the most important applications of the technology.
