Paper Abstract

In this paper we compare differential quadrature phase-shift-keying (DQPSK) and quaternary differential phase amplitude-shift-keying (QDPASK) transmissions in 80Gb/s optical communication systems with highly nonlinear fiber (HNLF) channel and evaluate their tolerance against channel nonlinearity and receiver interferometer phase error (IPE). The results show that QDPASK signal has better receiver IPE tolerance while DQPSK signal has better channel nonlinearity tolerance. The performance of DQPSK system is better than QDPASK system only when IPE is not serious.
