Optical Wireless Transmitting Communications Based Satellite Orbit to Orbit Communication Systems Enhancement with EDFA Amplifiers

This paper has demonstrated the effect of adding EDFA to satellite wireless optical communication system transmitter, also, demonstrated the effect of the change of length and characteristics of EDFA, telescope aperture length and input power in expanding the length of communication between two satellites in deferent orbits, then enhancing the output by using low pass filter. Optiwave 7 simulator was used to simulate the transmitter and receiver output. Modulation format used was NRZ (Non return to zero), the results was to compare the output of the receiver with different distance lengths between the satellites. As will as the output parameters such as BER, output power, Gain and the eye diagram was measured in the paper.
