Abstract :
A single-polarisation single-mode (SPSM) fibre with crosstalk of ¿40 dB in a 3.2 km length has been demonstrated. No crosstalk degradation was found for lengths of more than 0.2 km. The two polarisations of the fundamental mode were split with a high modal birefringence of 8.5×10¿4, which was produced by PANDA structure. The transmission loss was 2.8 dB/km at 1.56 ¿m.
