Abstract :
High-bit-rate (10 Gbit/s, 1.55 μm) phase-encoded duobinary transmission over nondispersion shifted fibre links using grating dispersion compensators is analysed. A reduced sensitivity to optical nonlinearities allows increased transmission powers and thus the distance, 1700 km compared to 1000 km for the conventional NRZ format. In addition, for typical links around 700 km, an increased dispersion margin is observed, equivalent to ±60 km compared with ±25 km for the NRZ format
