Abstract:
An optical signal processor device (14) intended to be fitted to means (10) for optically transmitting an information-carrying signal (S) comprises means (20, 22) for suppressing backscattered signals (RS) in the optical transmission means (10), an optical propagation medium (16) intended to be connected in parallel with the optical transmission means (10), divertor means (18, 20) for diverting the backs-propagated signals (P, RS) in the optical transmission means (10) into the optical propagation medium (16), and signal discrimination means (22) connected to the optical propagation medium (16).
