| 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 ).
