Abstract :
This paper presents an electrical equalizer suitable for optical communications systems using the standard single mode fibre (SMF) and based on dispersion supported transmission (DST). It is shown that using the electrical equalizer and the DST technique it is possible to transmit at very high bit rates (20 Gbit/s) and long distances (40 km), well beyond the dispersion limit. The equalizer was designed using a GaAs monolithic technology and has the main advantages of being electrically adjustable, a good input and output impedance match and also a small size
