Abstract
(EN)
A PD (110) receives the optical signal sent from an optical transmitter. A preamble detector section (144) detects a preamble signal contained in the signal received by the PD (110). An intensity ratio calculation section (146) calculates the dispersion quantity of the preamble signal in accordance with the waveform of the preamble signal detected by the preamble detector section (144). An electrical dispersion compensator (150) performs dispersion compensation to the signal received by the PD (110) depending on the dispersion quantity calculated by the intensity ratio calculation section (146).
(FR)
Un PD (110) reçoit le signal optique envoyé par un émetteur optique. Une section du détecteur de préambule (144) détecte un signal de préambule contenu dans le signal reçu par le PD (110). Une section calcul du rapport d'intensité (146) calcule la quantité de dispersion du signal de préambule conformément à la forme d'onde du signal de préambule détecté par la section du détecteur de préambule (144). Un compensateur de dispersion électrique (150) effectue une compensation de dispersion sur le signal reçu par le PD (110) en fonction de la quantité de dispersion calculée par la section calcul du rapport d'intensité (146).
