Significant Results

• ASE noise is the most dominating noise at low and
  medium link losses, but at very high link losses
  the thermal noise becomes as a dominating noise.
• Higher wavelengths show less degree of saturation
  and ultimately better BER performance of M-QAM
  signal.
• The receiver amplifier performs better than the
  other two amplifier positions (power and in-line
  amplifier) the link at high link losses, because
  the amplifier placed at the receiver end
  experience less degree of saturation due to link
  losses.
