“…Erbium-doped fibre amplifiers (EDFAs) are the most frequently used type of amplifiers in modern optical networks, as they operate in the wavelength region where minimal optical signal attenuation is observed (1530-1565 nm) in standard single mode fibres, and as they are relatively easy to build. EDFAs are also known for their high energy transfer efficiency (> 50 % of pump energy is used for excitation of Er +3 ions), almost complete polarization insensitivity and relatively low noise characteristics [4], [5].…”

“…Furthermore, the performance of the amplifier is also highly dependent on the conditions in which the amplifier is operating. Any adjustments in system configuration that will lead to changes in input signal power or the width of the wavelength band to be amplified will impact the total system performance as well as the configuration of the EDFA that would be optimal for the system under attention [5], [8].…”

The article investigates dependence of EDFA performance on its operating conditions. First of all, the impact of changes in channel spacing on the quality of the amplifier signal and on the desired EDFA configuration is observed – three different values of channel spacing are considered – 37.5 GHz, 50 GHz and 100 GHz. Afterwards, the impact of EDFA positioning on the quality of the amplified signal and the desired configuration is assessed. Three different EDFA positioning scenarios are considered – when the EDFA is used as a power booster, as an in-line amplifier and as a preamplifier. In all cases, such configuration of the EDFA is found that can ensure bit-error ratio (BER) values below 1·10−9 in all channels of the system. To assess the performance of the amplifiers, power penalty values are obtained in respect to identical transmission systems but without amplification.
