Abstract
The differential pulse position modulation (DPPM) is analyzed. Considering various engineering factors, the modulation order and transmission rate of DPMM are confirmed. The parameter budget method of pulsed fiber laser is proposed, and the parameters such as repetition frequency and linewidth are estimated. The link formula of deep space optical communication is established. The relationship between transmitting power, link distance and receiving power is analyzed, and the average power and peak power of laser are designed. Simulation results show that when the modulation order of DPPM is 8, the transmission rate is 500Mbps, and the repetition frequency of pulse fiber laser is 500MHz, the linewidth is 0.1ns, the average transmitting power is 6.8W, the peak power is 1000W, it can meet the ultra long distance 150,000 km deep space optical communication needs.
