Abstract:

This paper presents the combination of pulse position modulation (PPM) and pulsed fiber laser in order to improve the problem that the pulsed fiber laser with high power but low repetition frequency results in lower data transmission rate and limits its application. We compare the bandwidth requirement, power requirement, bandwidth utilization and error performance of several schemes of LPPM, DPPM, MPPM and OOK. Also, the modulation rate of three PPM based on fiber laser is obtained. It is shown that DPPM performs best in bandwidth requirement, bandwidth utilization and modulation rate. Moreover, DPPM doesn’t require symbol synchronization, which is of great importance in optical communication system. Then the optimal value for DPPM and modulation characteristic of fiber laser are presented. Finally, through simulation and test, we get the results, which shows the feasibility of the scheme.
