Study on Optical Performance Monitoring for Fiber-Optical Link Utilizing Chaos Theory

摘要

Optical-link performance monitoring (OLPM) plays a crucial role in ensuring the link performance, the channel assignment and the network reconfiguration in the high-speed and WDM optical networks. An OLPM scheme based on the chaos theory and the pattern recognition is proposed in this paper. The identification results of nonlinear regimes of 4/8/16-channel WDM links with 10 Gb/s are demonstrated through utilizing the maximum Lyapunov exponent, the recurrence plot and the two-layer perceptron.
