Method and apparatus for determining an optical signal-to-noise ratio (OSNR) penalty
摘要
Method and apparatus for determining an optical signal-to-noise ratio (OSNR) penalty. A method for determining an optical signal-to-noise ratio penalty as a measure for a quality of an optical signal transmitted via an optical link between a source optical node and a destination optical node in an optical network, the method comprises collecting (101) information of the optical link; determining (103) a configuration parameter Pconf of the optical link based on the information of the optical link; adjusting (105) the configuration parameter Pconf to an adjusted configuration parameter Pconf according to linear impairments in the optical link; and determining (107) the optical signal-to-noise ratio penalty based on a non-linear function of the adjusted configuration parameter Pconf, the non-linear function accounting for non-linear impairments in the optical link.
