In the high-speed system of space optical communication, NRZ modulation on differential phase shift keying, 66% duty cycle RZ modulation and 33% duty cycle RZ modulation. By using the Optisystem optical communication software design of DPSK optical communication system based on communication rate in 40Gb/s, the signal power is -42dBm, at a distance of 100 km for atmospheric channel 0.5dB/km transmission attenuation and then through the light of the noise coefficient of 3.2 dB preamplifier makes
more » ... light signal gain after reaching 40 dB, compares different modulation modes respectively discussed.
