Abstract :
The measurement of chromatic dispersion in single-mode fibres using a 1300 nm edge-emitting LED, a 1550 nm laser diode, and the phase shift method are described. The approach is insensitive to fibre temperature change throughout the measurement, and may enable dispersion in single-mode fibre optimised for 1300 nm operation to be characterised in the 1500 nm region, as well as in the 1300 nm region. The influence of the edge-emitting LED on the measurement is also considered, in that error can arise through selecting narrow wavelength regions of its output, and matching its wavelength coverage to the fibre zero dispersion region is important for long length characterisation. Measurements on installed SM fibres are discussed
