Future converged fixed-mobile networks need high-speed radio links in deployment scenarios where fibre is not available or too expensive. In this paper, we present a field-programmable gate array (FPGA)-based real-time transmission system using standard 10G Ethernet interfaces. The system comprises two parallel complex-valued data channels in each(More)
The numerical modelling of four-wave mixing in ultralong semiconductor optical amplifiers (UL-SOAs) is discussed. Inside the UL-SOA, complex wave mixing interactions take place so that time-domain modelling is an important requirement for the simulation model. We validate our simulations by comparison with measurements and show that the confinement factor(More)
We will present techniques for all-optical wavelength conversion of phase-modulated signals using four-wave mixing and supercontinuum generation. Techniques for the improvement of the conversion efficiency will be studied. Mainly the suppression of Brillouin scattering and its impact on phase-distortions will be discussed. An assessment of its cascadability(More)
