Abstract (en)
[origin: WO9428647A1] The aim of the present invention is to provide an arrangement for monitoring and automatically resetting a light-guide transmission section which can also be used at very high optical transmission powers without presenting a hazard to people when repairing the transmission section. This aim is achieved by the invention in that the test pulses used are reduced to a safe level. Highly sensitive detectors must be used on the receiver side to detect the test pulses. Application, for example, in the long-distance transmission with optical fibre amplifiers as output amplifiers.
