Abstract :
Inter-symbol interference caused by filtering effect in the all-optical optical cross-connect (OXC) will lead to degradation of optical signal. We investigate the effect of 40 Gb/s data ISI in the OXC nodes with different modulation formats and various parameters including channel spacing, OXC cascading, and passband profile. We show that waveband switching OXC causes less ISI effect to the signals.
