Patent ID: 7209604

Claim:
An anti-PMD system comprising: an anti-PMD pulley ( 1 ) over which an optical fiber ( 4 ) is to roll and which is mounted to rotate about an axis of rotation (ar); and at least two optical fiber guide devices ( 2 , 3 ) situated on either side of the anti-PMD pulley ( 1 ); the system being characterized in that the axis of rotation (ar) of the anti-PMD pulley ( 1 ) is stationary; in that the only degree of freedom of the anti-PMD pulley ( 1 ) is rotation about the axis of rotation (ar) of the anti-PMD pulley ( 1 ); and in that at least one of the guide devices ( 2 , 3 ) is movable in translation in a translation direction (dt) that is not orthogonal to the axis of rotation (ar) of the anti-PMD pulley ( 1 ).
