Abstract
Recent advances in DWDM system designs have led to a significant increase in the number of wavelengths in a single fiber. As network architects start to apply DWDM to regional and metro networks high performance characteristics for mux/demux (narrow and gaussian passband, weak insertion and polarization-dependent loss, low group delay responses,...) are needed. Accurate measurements of these characteristics become also necessary. In this paper, we focus on the determination of the passband and group delay of a free space optics DWDM and show that the optical low-coherence reflectometry is an efficient method for this kind of measurement.
