We describe an all-fibre, passive scheme for making extended range interferometric measurements based on the dual wavelength technique, The coherence tuned interferometer network is illuminated with a single superfluorescent fibre source at 1.55 mu m and the two wavelengths are synthesised at the output by means of chirped fibre Bragg gratings. We demonstrate an unambiguous sensing range of 270 mu m, with a dynamic range of 2.7 x 10(5).
