Abstract :
A novel optical duobinary detection scheme that optimises the sampling phase of the receiver based on preliminary sequence decision is proposed. Simulation results show significant improvement in dispersion tolerance and back-to-back sensitivity. An implementation using an over-sampling frontend, which is compatible with other designs of electrical dispersion compensation receivers, is also proposed.
