An analysis is presented for an optical fiber n-ary pulse position modulation (PPM) system employing optical preamplification. Calculations, performed at a bit-rate of 622 Mbit/s and a wavelength of 1.53 micrometers , demonstrate that the incorporation of an optical preamplifier leads to a sensitivity benefit of 13.3 dB compared to the non-preamplified case and a sensitivity improvement of 7.5 dB over an equivalent PCM system. Further, the work also shows that sensitivities approaching that of homodyne PSK PCM are potentially achievable.
