Abstract :
Chromatic dispersion (CD) equalisation will be discussed in this paper with an alternative method, cascaded parallel optical all pass filter (Cp-OAPF), to equalise within a 10 Gb/s single mode fibre (SMF). The CD is due to the phase delay within the SMF. The Cp-OAPF acts as a phase equaliser which will invert the effect of SMF phase delay. Simulation results at BER of 10-9 showed that the proposed equaliser can increase of 1.6 times in the CD equalisation range compared to system employing p-OAPF with nonreturn to zero rectangular and Gaussian pulses at 10Gb/s. The Cp-OAPF is capable to compensate CD over a wide range of 109 and 98 km when the input is rectangular and Gaussian pulse, respectively for error free BER.
