Abstract
A method for stabilization of a transparent photonic network having at least one WDM path which has a specific number of channels on which signals can be transmitted, and a method for reconfiguration of a transparent photonic network from a first WDM path to a second WDM path between two points which have a number of channels on which signals can be transmitted.
Claims10
A method for stabilizing a transparent photonic network having at least one WDM path which has a specific number of channels on which signals are transmitted, the transparent photonic network being subject to level fluctuations caused by connection and disconnection of channels, the method comprising:
- switching signals of the transparent photonic network based on individual wavelengths;
- maintaining constant a number of the channels allocated to a particular signal of the signals switched;
- and
- maintaining constant a channel power level corresponding to the particular signal at an input of the at least one WDM path, wherein maintaining constant the number of channels and the channel power level substantially stabilizes the level fluctuations caused by the connection and disconnection of the channels in the transparent photonic network.
An apparatus for stabilizing a transparent photonic network subject to level fluctuations caused by connection and disconnection of channels, the apparatus comprising:
- at least one WDM path having a specific number of channels on which signals are transmitted;
- and
- a transparent optical switching matrix for switching the signals of the transparent photonic network based on individual wavelengths;
- wherein the transparent optical switching matrix maintains constant a number of the channels allocated to a particular signal of the signals switched, and wherein the transparent optical switching matrix maintains constant a channel power level corresponding to the particular signal at an input of the at least one WDM path such that the level fluctuations caused by the connection and disconnection of the channels in the transparent photonic network are substantially stabilized.
