Abstract
A novel carrier-suppressed return-to-zero frequency shift keying (CSRZFSK) transmitter that can operate at 40 Gb/s and above is proposed for the first time. The transmission characteristics of the CSRZFSK signal at 40 Gb/s compared with differential quadrature phase shift keying (DQPSK) signal and amplitude shift keying (ASK) signal are investigated under different dispersion management. Simulation results show that CSRZFSK has the best nonlinear tolerance and longest transmission distance when compared with DQPSK and ASK signals. A 40 Gb/s CSRZFSK signal gives only a 0.1 dB sensitivity penalty while DQPSK and ASK give 0.6 and 0.7 dB, respectively.
