A remote strain sensor with a lead fiber length of 3.3 km and an ultraweak fiber Bragg grating with reflectivity of 0.015% was demonstrated. A demodulation technique based on methods of the differential spectroscopy allows interrogating FBG with reflectance much below the Rayleigh backscattering coefficient.
