ABSTRACT:
A receiver device for optical data signals, in particular optical data signals in the Gb/s range, comprising an opto-electrical conversion unit, a frequency multiplicator unit (24) for frequency-multiplying the converted electrical data signal, and a clock recovery unit is characterized in that the frequency multiplicator unit (24) performs a frequency multiplication by a factor of n, with n being a natural number larger than 2. The receiver device has an improved tolerance on dispersion as far as generating a clock line is concerned.
