Abstract

Transmission in a 40-Gbit/s alternating-phase (0 and π) duobinary modulation format with 67%, 50%, and 33% pulse width [modulation duobinary carrier suppression (CS) and carrier maximum pulse carving] is demonstrated. A minimum 136-ps/nm dispersion tolerance can be achieved at this transmission rate. At least 5- and 1.2-dB receiver sensitivity improvements are achieved for CS return-to-zero (RZ) 67% and 50% duobinary modulation, respectively, as compared with the experimental measurement under CS RZ differential phase-shift keying transmission over a 320-km three-span optically amplified dispersion-compensated standard single-mode fiber system. A MATLAB Simulink platform is described for simulation of the transmission performance.
