  • Erbium Doped Fiber Amplifier.


Sorry, no etymologies found.


  • So until proper photon amplifiers arrived in the late 1980s the erbium-doped fiber amplifier, or EDFA, this was like taking a message off the freeway every few miles, putting it on a frontage road for electronic manipulation, then putting it back on the freeway again.

    The Nature of Technology

  • The introduction of integrated EDFA increases the dynamic range to 20dB.

  • The pump wavelength, usually at 980 nm or sometimes 1480 nm, is coupled to the Erbium doped fiber at the input, while any residual pump power is removed at the EDFA output by a second coupler.
