Proposed is a method of compensating chromatic dispersion and nonlinear impairments of an optical transmission path. The method comprises steps of deriving a digital electrical signal corresponding to a received optical transmission signal, determining from the derived electrical signal an overall amount of accumulated chromatic dispersion of the optical transmission path, and filtering the electrical signal, by alternating between filtering steps of a first type, which compensate for respective partial amounts of accumulated chromatic dispersion, and filtering steps of a second type, which compensate for respective partial amounts of nonlinear impairments. |
