  • Signal Processor for Compensating for Optical Fiber Chromatic Dispersion
    Publication number: 20100061738
    Abstract: A signal processor for compensating for optical fibre chromatic dispersion comprising encoding means (5) for encoding a source signal (2) received from a data source (6), splitting means (8) to separate the encoded signal (7) from the encoding means (5) into an in-phase component (10) and an in-quadrature component (11), a first filter means (12) adapted to receive the in-phase component (10) and a second filter means (13) adapted to receive the in-quadrature component (11), the first filter means (12) and second filter means (13) being adapted to filter the in-phase and in-quadrature components respectively. The outputs (14, 15) from the filter means form the input to the optical modulator means (3).
