A simple analytical expression is derived to calculate the Bit-Error Rate in lightwave systems with optical amplifiers. According to this expression the Bit-Error Rate can be estimated by the signal power and the ASE spectrum density before the receiver. The theoretical calculation agrees with the experiment very well, so it can provide a method to judge the quality of the optical channel in the optical communication system with optical amplifiers. Futhermore, the impact of the ASE noise on the receiver sensitivity is discussed. It is important to select proper receivers in practical systems.

Wavelength Division Multiplexing is a technology that has enabled the transmission of huge amounts of data at high transfer rates over a single optical fiber. The capacity of an optical channel is usually affected by the shape of signal, nonlinear characteristics and dispersion. In this article, we focus on the DWDM system, optical amplifiers, and optical modulations in 32-channel DWDM system, which was designed in the OptiSystem program. We evaluate the parameters BER (Bit Error Rate) and Q factor for 40 Gb/s systems with changing amplifiers.
