Abstract
Equalizers based upon a simple length of waveguide or microstrip have been demonstrated for this application. As the required length of the equalizer is dependent on the fiber span, then for very long transmission distances these approaches tend to become rather impractical. We have explored an alternative pseudo-lumped-element approach utilizing GaAs monolithic microwave integrated circuit (MMIC) technology, providing very compact group delay equalizers which may readily be integrated with other receiver signal processing functions. We have previously published preliminary results obtained with single network sections. These provide the requisite dispersion compensation over a restricted bandwidth. Here for the first time, we explore how multi-section GaAs MMIC group delay networks may be employed to achieve dispersion compensation over a much wider frequency range, illustrating the effectiveness of the approach with reference to an 8 Gbit/s 200 km system application.
