Abstract :
We propose a scheme of multiple 16QAM signals generation at 40 Gbit/s using a novel transmitter. The scheme is based on a dual-parallel Mach-Zehnder modulator (DPMZM) and a following phase modulator (PM). We demonstrate the proposed transmitter by VPI simulation and three types of 16QAM signals are obtained, which shows the feasibility of the transmitter. In order to further investigate the transmission performance, the generated 16QAM signals are transmitted through 80-km standard single-mode fiber (SSMF) and detected by a coherent receiver and error free performance is achieved.
