ED-AMP: Erbium Doped Fibre Amplifiers

ED-AMP

ED-AMP allows full characterisation of the gain and noise performance of one of the key components in long distance optical fibre communication systems, the erbium doped fibre amplifier.

Experiments Examine:

  • EDFA gain variation with signal & pump power
  • Small & large signal gains, gain saturation
  • Transparency, gain gradient and gain efficiency
  • Pump saturation & saturated output power
  • Amplified spontaneous emission (ASE) levels
  • ASE-ASE & Signal-ASE beat noise
  • Output SNR & Noise Figure
  • Impact of optical filter on ASE & noise levels
