Abstract :
The detection of the signal backscattered by the faults present in an optical fibre is achieved by observing the amplified signal coming out by the rear facet of the exciting laser source. This provides a simple method which employs the same semiconductor laser as a source and an amplifier, thus notably simplifying the procedure for fault detection. Some experimental results are presented.
