Performance assessment of a photonic ATM switch based on a wavelength-controlled fiber loop buffer

Summary form only given. We report the first BER measurement of a photonic switch based on a wavelength-controlled fiber loop buffer, in real operation, i.e., with computer-generated repeated random input traffic, with all interfering and noise sources. Further measurements will be carried out in the near future and compared to a simulation model, regarding the influence of wavelength crosstalks, number of circulations, and wavelength allocation.
