Abstract: Component signal values are derived from component signals and fed to at least one fixed equalizer which generates equalizer output signals. The signals are fed to phase error detectors generating phase error signals. The phase error signals are combined with further phase error signals derived by further error detectors receiving signal values from further equalizers and/or the component signal values directly from sample units.

Abstract: A method and device is provided for reducing optical transmission impairments, particularly nonlinear effects, of at least one link Said method comprising the following steps: extracting a phase information (Δθ) from an optical signal (120) received via that at least one link, determining a nonlinear coefficient (γ), associated with the at least one link, based on the phase information (Δθ), applying a control mechanism (202) using the nonlinear coefficient (γ). Furthermore, a communication system is suggested comprising said device.
