Abstract :
Polarisation-mode dispersion and fibre length dependence of extinction ratio between two orthogonally polarised HE11 modes are measured for predicting bandwidth limitation in high-capacity transmission systems. For a single-mode fibre with 10% core ellipticity and 0.5% refractive-index difference, 3 dB bandwidth and available bit rate after 50 km transmission are evaluated to be 4.8 GHz and 8.8 Gbit/s at v = 2.2, respectively.
