F. Bruyere et O. Audouin, PENALTIES IN LONG-HAUL OPTICAL AMPLIFIER SYSTEMS DUE TO POLARIZATION-DEPENDENT LOSS AND GAIN, IEEE photonics technology letters, 6(5), 1994, pp. 654-656
The impact of Polarization Dependent Gain (PDG) and Polarization Depen
dent Loss (PDL) in long-haul optical amplifier systems is studied by m
eans of a power analysis accounting for PDG, PDL and Polarization Mode
Dispersion (PMD) in the saturation regime of the Erbium-Doped Fiber A
mplifiers (EDFAs). System penalties are characterized in terms of mean
values and standard deviations. Mean penalties on the bit-error-ratio
(BER) are directly related to PDG. BER fluctuations are found to be g
reatly enhanced when PDG and PDL are combined. The impact of PMD is de
pendent on the values for PDG and PDL.
