A technique for reducing signal degradation and fading within a long optical transmission by utilizing a rotating waveplate arrangement to rotate the SOP of an optical signal launched into the transmission system, and thereby minimize polarization dependent hole-burning ("PDHB"). This effectively reduces the degree of polarization of the launched optical signal, without degrading the noise and dispersion characteristics of the signal. The rate of waveplate rotation is chosen to ensure that the SOP of the launched signal does not remain at a particular SOP long enough to anisotropically saturate any optical amplifier employed within the transmission system, and give rise to PDHB.

Technique permettant de réduire la dégradation et l'évanouissement d'un signal lors d'une longue transmission optique en faisant appel à un arrangement par lame-onde rotative pour faire tourner l'état de polarisation d'un signal optique lancé dans le système de transmission et minimiser de la sorte la saturation sélective due à la polarisation. Cela permet de réduire efficacement le niveau de polarisation du signal optique transmis, sans provoquer d'altération des caractéristiques de bruit et de dispersion du signal. Le taux de rotation de la lame-onde est choisi de manière à ce que l'état de polarisation du signal ne soit pas maintenu assez longtemps pour saturer anisotropiquement l'un des amplificateurs optiques utilisé dans le système de transmission et provoquer des trous de transmission dus au bruit engendré par la polarisation.
