Cumulative attenuation and dispersion were measured along a 11.7 km fibre link consisting of 10 spliced fibres and compared to measurements on the individual fibres. Four different procedures were used for the loss measurements, and the effect of transient losses has been investigated. Good agreement was obtained between predicted and measured losses in the link provided transient losses due to high-order modes were eliminated in the individual measurements. Pulse dispersion measurements were made without the use of any mode scrambler. The cumulative dispersion measurements clearly showed a significant correlation between non-adjoining fibres, and the observed pulse width exhibited more of a linear than a square root dependence on length.
