Noun
EDFA (plural EDFAs)
(electronics) Initialism of Erbium-Doped Fiber Amplifier.
Basic principle of EDFA A relatively high-powered beam of light is mixed with the input signal using a wavelength selective coupler (WSC). Source: Internet
It can be potentially less expensive than the EDFA and can be integrated with semiconductor lasers, modulators, etc. However, the performance is still not comparable with the EDFA. Source: Internet
The gain spectrum of the EDFA has several peaks that are smeared by the above broadening mechanisms. Source: Internet
