Margin-based optimization systems and methods in optical networks for capacity boosting

摘要

Systems and methods of optimizing capacity of an optical network include identifying a first wavelength with an associated target capacity; determining that the first wavelength has insufficient capability to operate at the associated target capacity; and adjusting one or more wavelengths to increase capability of the first wavelength such that the first wavelength can operate at the associated target capacity.

1. A method of optimizing capacity of an optical network, the method comprising:
identifying a first wavelength with an associated target capacity; determining that the first wavelength has insufficient capability to operate at the associated target capacity by comparing one or more parameters associated with the first wavelength to one or more predetermined thresholds; performing a nonlinear optimization of excess margin in the optical network, the performing comprising modeling bit rate, Optical Signal to Noise Ratio (OSNR), and whether or not a wavelength can support additional capacity as real functions; and adjusting one or more wavelengths in the optical network separate from the first wavelength to increase capability of the first wavelength to operate at the associated target capacity, wherein the adjusting is in response to a result of the nonlinear optimization.
