Abstract
The present invention relates to a method and a device for detecting damages in an optical fibre () made for transmitting high optical power, specifically power exceeding 1 kW, and where the optical fibre () has an entrance end () for incident optical radiation () and an exit end where the optical radiation is leaving the fibre. According to the invention substantially radially spread radiation in connection with the entrance and/or exit parts of the fibre is detected, and if this radiation exceeds a certain level this is used as an indication of a damage in the entrance and/or exit zone of the fibre.
