Control pulse impairments including imperfect misalignment and address matching false alarm would deteriorate the performance of the all-optical routing and switching. In this paper we evaluate these effects on the performance of an all-optical pulse-position-modulation router. The VPI™ simulation results indicate that the misalignment of control pulse and data signal would reduce several dB in switching gain of the all-optical AND gate that reduces the reliability of the system. In addition a minimum switching contrast ratio of +17.5 dB at the pulse-position-modulation header processing module is required to ensure false-alarm free in matching the packet address with the routing table entries.
