Abstract: The technology of combining a number of optical wavelengths and then transmitting the same through a single fiber is called wavelength division multiplexing (WDM). Conceptually, the technology is similar to that of frequency division multiplexing (FDM) used in analog transmission. Dense wavelength division multiplexing (DWDM) is a new born multiplexing technology in the fiber optic transmission, bringing about a revolution in the bit rate carrying capacity over a single fiber. DWDM technology make efficient utilization of bandwidth and low attenuation characteristics of single mode fibers and uses multiple wavelength as carriers and allow them to transmit in the fiber simultaneously .When compared to common single channel system , Dense wavelength division multiplexing greatly increases the network capacity and make efficient use of the bandwidth resource of optical fibers. The emergent of DWDM system is one of the important phenomena in development of optic fiber transmission. This article gives introduction of DWDM technology.
