(1) The distance between two corresponding points in a series of waves. (2) With respect to optical fiber communications, the distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. Wavelengths of light are measured in nanometers or micrometers. Wavelength is preferred over the term frequency when describing light.

|WDM Wavelength division multiplexing||
A method of carrying multiple channels through a fiber at the same time (multiplexing) whereby signals within a small spectral range are transmitted at different wavelengths through the same optical-fiber cable. See also frequency division multiplexing.
