A sine generation method that the different frequent sine signals can be generated by the different Pulse-Width Modulation (PWM) signals generated by Field-Programmable Gate Array (FPGA) through low-pass filter of fixed parameters was proposed. The method just takes a few FPGA resources and was proved feasible by the theory. The experiment results and theory analysis tally.

The first and second-order polarization mode dispersion (PMD) effect on the performance of 10 Gbit/s and 40 Gbit/s systems is studied. The statistical behavior of PMD is considered by simulating the nonreturn-to-zero (NRZ) and return-to-zero (RZ) pulses distortion and the system's Q-factor based on principal states of polarization (PSP) theory. It is found that the effect of PMD is significant in higher bit rate systems and the second-order PMD cannot be neglected. Furthermore, the RZ format is more tolerant to PMD than is the NRZ format, and the system performance is improved if the input pulses are appropriately chirped.
