【 摘 要 】

We study a design and limitations of a wavelength division multiplexing packet- switched network based on semiconductor optical amplifiers (SOAs) under different modulations formats (QPSK, 8-QAM and 16-QAM). A simple convergence rule for accumulated SOA nonlinearities based on the so-called nonlinear threshold is proposed. We calculate the signal reach depending on various SOA and network parameters by means of numerical simulation. We provide a design tool enabling optimization of a SOA-based optical network architecture.
