Organization: ITU-T
Publication Date: 1 December 2003
Status: active
Page Count: 12
scope:

The purpose of this Recommendation is to provide the definition of a wavelength grid to support coarse wavelength division multiplexing (CWDM) applications. This grid is designed to allow simultaneous transmission of several wavelengths with sufficient separation to permit the use of uncooled sources.
