Abstract
Throughput efficiences and alignment tolerances for coupling lasers to long (≳ 1 km) fibres are strongly dependent on the fibre modal excitation. It is found that, for accurately predicting system performance and for determining packaging tolerance requirements, laser-fibre coupling measurements should be made with long fibres.Keywords
