WDM(1) (Wavelength Division Multiplexing) A technology that uses multiple lasers and transmits several wavelengths of light (lambdas) simultaneously over a single optical fiber. Each signal travels within its unique color band, which is modulated by the data (text, voice, video, etc.). WDM has dramatically increased the carrying capacity of the fiber infrastructure of the telephone companies and other carriers. Also known as "dense WDM" (DWDM), vendors have introduced systems that can support hundreds of wavelengths, each carrying 10 Gbps. That means terabits of data per second can travel over one optical strand, thinner than a human hair. Contrast with TDM. See CWDM and fiber optics glossary. See also FDM.

To increase the transmission capacity, we had to achieve two goals simultaneously: WDM transmission with high spectral efficiency and optical amplifiers with greatly enlarged bandwidth. From our optical Ethernet and WDM platforms to our installation and support services, we want to help customers roll-out profitable new services with minimal risk. Current WDM systems typically employ 50 GHz or 100 GHz channel spacing (0. |
