Anotace: 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.
