Abstract: We experimentally observe the nonlinear dynamics of an optoelectronictime-delayed feedback loop designed for chaotic communication using commercialfiber optic links, and we simulate the system using delay differentialequations. We show that synchronization of a numerical model to experimentalmeasurements provides a new way to assimilate data and forecast the future ofthis time-delayed high-dimensional system. For this system, which has afeedback time delay of 22 ns, we show that one can predict the time series forup to several delay periods, when the dynamics is about 15 dimensional.
