Abstract
Exemplary embodiments of the invention are drawn to a method and apparatus for the differentiation of power and channel count changes in optically amplified links. Additionally, configuration of a corresponding optical amplifier can be based on the determination of the power and channel count changes.
Claims20
A method comprising:
- measuring a first parameter from a first signal received at a node;
- measuring a second parameter from a second signal received at the node;
- comparing the first parameter to a third parameter and the second parameter to a fourth parameter;
- and
- identifying a type of system perturbation based on the comparisons.
