Abstract

An architecture of wavelength division multiplexing (WDM) optical packet switching (OPS) router with all-optical regenerators is proposed. The regenerator based on phase-sensitive amplifier (PSA) can simultaneously provide phase and amplitude regeneration for quadrature phase-shift keying (QPSK) or differential quadrature phase-shift keying (DQPSK) signals. The simulation results show that three regenerators are sufficient for an OPS router in a node with a nodal degree of five to keep blocking probability below 5% and throughput ratio above 95% under different intensities of self-similar traffic load.
