Abstract

In current high bit rate long haul point to point optical communication system, the chromatic dispersion of a single mode fibre is the main limitation to increase the bit rate. This paper proposes a promising technique to compensate chromatic dispersion, hence improving the bit error rate and repeater-less span. This compensation scheme uses an optical all pass filter equaliser that is optimised by minimum mean square error technique. The practical implementation of an optical all pass filter using passive infinite impulse response digital filter structure is also introduced. The simulated results showed that a dispersed rectangular pulse is fully compensated at full-width half at maximum after propagating 160 km of SMF and the resultant eye pattern showed an improvement to the bit error rate when the proposed optical all pass filter equaliser is used.
