Optical receiver and method for chromatic dispersion compensation

摘要

An optical receiver (5) for an optical network (2) comprises a dispersion compensation module (7) for adjusting an amount of chromatic dispersion of optical signals transmitted through the optical network (2) and is characterized in that a nonlinear optical element (13) for spectral broadening of a dispersion probe signal transmitted through the optical network (2) is arranged in a measuring path (11) downstream of the dispersion compensation module (7), and a power measuring means (15) for measuring an average power of the optical dispersion probe signal over a predetermined frequency range is arranged downstream of the nonlinear optical element (13) in the measuring path (11).
