Summary:ab ab ba abab An optical transducer and method for the simultaneous measurement of downhole pressure and temperature in a single- or multi-point configuration including a body with an elastic membrane onto which at least one Bragg grating is attached, and at least an additional Bragg grating contained on the same optical fiber . The elastic membrane conveys strain proportional to the pressure and temperature conditions to which is submitted said transducer to at least one Bragg grating , the portion of light not reflected by the Bragg gratings continues along the remaining of the optical fiber
