Abstract
A novel method is described which is suitable for measuring the chromatic dispersion of installed single-mode fibres by using a modified σ-type Sagnac interferometer, which contains an off-centred phase modulator. Chromatic dispersion is measured with high resolution from the output interference fringe without requiring any fast diagnostic equipment. Measurement of the chromatic dispersion of a single-mode fibre in the wavelength range 1.5-1.58 μm is demonstrated
