Wavelength division multiplexing (WDM) has been emerging as an effective technique for making use of the full bandwidth offered by optical fiber. To achieve long-haul transmission, erbium-doped fiber amplifiers (EDFAs) are employed to compensate for signal attenuation without using optoelectronic/electro-optic conversions. Transmission in these systems is limited by fiber nonlinearities and amplified spontaneous emission noise from amplifiers. In this paper, the long-haul optical WDM system with EDFAs is investigated theoretically. The noise and bit error rate (BER) characteristics of the system with optical amplifiers are calculated and the dependence of the BER on interamplifier separation and input power is shown.
