Abstract
Channels are groomed in a wavelength division multiplexed (WDM) communication system having a plurality of system nodes interconnected together by a ring formation of optical fiber waveguides for guiding communication traffic bearing radiation between the nodes. The radiation comprises a plurality of wavelength channels for conveying communication traffic. The channels are spaced over a channel wavelength spectrum. The wavelength channels being used within the system are selected to convey communication traffic (active channels) such as to consolidate them into a relatively more compact part or parts of the wavelength spectrum such as to occupy less communication bandwidth.
