A method is described for the safe automatic restart of optical transmitters (TX1, TX2) in a fiber optic telecommunication system. The method comprises the steps of monitoring the status of the system connections through an out-of-band signaling channel, in particular an Optical Supervisory Channel (OSC), through the transmission and the reception of signals (S1, S2) and restoring the optical transmitters only after having received the confirmation (S1) that the transmissive optical medium does not exhibit breaks. <IMAGE> |
