| Distinct from | iqbal2011optical The attack and the defence. Iqbal, Fathallah and Belhadj survey fibre tapping methods and close by proposing countermeasures; this is one of those countermeasures built and tested -- a pulsed Mach-Zehnder interferometer that detects the tap rather than preventing it. Read the survey first. |

Abstract
A modified optical fibre based Mach-Zehnder interferometer was applied as a sensor to detect wiretapping in long transmission optical fibre lines. The signal consisting of short pulses (around 1 ns) was launched to the input of the interferometer based on the polarization maintaining fibres and polarization elements. When the sensing line was undisturbed, detectors registered only a single pulse. The additional two side pulses appear, if the wiretapping attempt took place. For robust detection of any alarm situation we proposed two-criteria algorithm to minimize false alarm rate. Moreover, slow environmental fluctuations were continuously monitored and compensated by polarization controllers. We measured frequency characteristics of the sensor and performed a hundred wiretapping attempts, which proved high performance of the sensor.
