Paper Abstract

Ultimate spectral efficiency of information transmission of erbium-doped fiber amplifiers and lumped amplifier chains is considered on the basis of the number-state model for linear communication channel. For single amplifier the efficiency is about 12-14 bit⋅s-1Hz-1 at 1 μW⋅GHz-1 input signal power density depending on pumping conditions. For long-haul communication lines it approximates 7-14 bit⋅s-1 Hz-1 for spectral density of input signal power of 1-100 μW⋅GHz-1.
