摘要
A method of configuring an optical path, comprising: selecting a path from a first to a second node in an optical communications network; identifying each wavelength that may be used continuously across the path and selecting a transmission wavelength for the optical path one of the identified wavelengths for which: a fixed wavelength direction-bound add/drop transponder add operable at said wavelength is available at each node; if that first requirement is not met, a fixed wavelength direction-bound add/drop transponder or a fixed wavelength directionless add/drop transponder operable at said wavelength is available at each node; and if that second requirement is not met, a tunable wavelength direction-bound add/drop transponder or a tunable wavelength directionless add/drop transponder operable at said wavelength is available at each node.
