Analysis of Optical Signal Transmission Characteristics

This paper reports the optical signal transmission characteristic in the G.652 fiber based on the software OpticSimu. The simulation results are in agreement with theoretical analysis. Without taking into account the non-linear effect and in the same condition, the longer the transmission distance, the signal distortion caused by the group velocity dispersion is clearer while the bit rate increasing. Through reducing the initial chirp of optical signal, the distortion can be reduced at fiber-optic transmission, and the transmission quality is improved.
