Abstract

Each station (for example 11a) of a stretch of a device (10) receives signals which are transmitted by a monomode fibre (A) which is configured to transport two different wavelengths ( lambda 1 and lambda 2). These signals are first separated by a demultiplexer (P). The signals having the wavelength ( lambda 1) are transmitted to a detector (D1), then regenerated by a regenerator (R) and fed to a multiplexer (N). The signals having the wavelength ( lambda 2) are transmitted to a divider (T) which separates a first part (S1) of these signals, which are transmitted to a second detector (D2), from a second part (S2) which likewise is fed to the multiplexer (N).
