Integrated electronic equalizer for dispersion compensation in 10 Gb/s fiber networks

The paper presents the design of a high-speed transversal equalizer for dispersion compensation in 10 Gb/s fiber networks. The five-tap equalizer is implemented in a 47 GHz SiGe technology. The equalizer circuit is optimized for minimum group delay and maximum bandwidth. With added feedback in the equalizer gain stage, we achieved minimum group delay of 0.7% data period. Polarization mode dispersion compensation has been demonstrated using the proposed transversal equalizer.
