"WDM-DPSK Detection by means of Frequency-Periodic Gaussian Filtering" CIARAMELLA, ERNESTO ; R. PROIETTI; L. GIORGI; CONTESTABILE, GIAMPIERO ; E. CIARAMELLA 2006-01-01 Abstract A single frequency-periodic narrow filter converts DPSK to intensity modulation in a high number of WDM channels. It also strongly enhances their tolerance to chromatic dispersion and is exploited in a 16x10 Gbit/s transmission over 240 km G.652 fibre with no chromatic dispersion compensation.
