Manufacturers : Optoelectronics : Fiber optics : Wavelength division multiplexers

Wavelength division multiplexing (WDM) enables different wavelengths to be simultaneously carried over a common fiber optic waveguide. Wavelength division multiplexing increases the information carrying capacity of optical transmissions for voice communications as well as high density transmission of data. Wavelength division optical transmission requires an optical multiplexer for combining individual optical signals into a multiplexed signal and an optical demultiplexer for separating the multiplexed signal back into its discrete wavelength components. A wavelength division multiplexer (WDM) is used to combine or separate optical signals having different wavelengths. Wavelength division demultiplexers are used in optical communication circuits to separate a plurality of signals transmitted on a common carrier based upon the wavelength of the light onto which the signal is modulated. Dense wavelength division multiplexers (DWDMs) are used in optical systems for functions of combining or separating optical signals with densely packed wavelengths. Wavelength division multiplexers and demultiplexers typically include various combinations of optical elements for performing the combination and separation function respectively. Wavelength division multiplexers can also be used in fiber optic communication systems for other purposes, such as dispersion compensation, noise reduction, and gain flatting, i.e., maintaining a uniform gain within the usable bandwidth for erbium doped amplifiers.
