Abstract

See full text

The invention relates to a method for retransmitting a probe signal, implemented by a device in a remote terminal (RT) connected to a central terminal (CT) by a monofibre optical line (MFOL), the probe signal being received by the remote terminal (RT) and having a predetermined wavelength (λprobe), the central and remote terminals exchanging over said optical lines useful data signals (λd, λu) having wavelengths other than those of the probe signal, including the following steps: receiving the polarised probe signal at a first polarity (P1); retransmitting the probe signal over the monofibre line toward the central terminal; and, prior to the retransmission step, a step of switching the first polarity (P1) of the probe signal to a second polarity (P2).
