Both attenuation and dispersion contribute to determine a maximum transmission span beyond which the optical signal that is, a suitable coding of an analog waveform or a sequence of digital pulses cannot be detected any longer nor decoded with sufficient precision for long distance transmission of information. The availability of optical amplifiers really represents a key point regarding the attenuation limit of optical networks. Optical amplification allows system designers to increase network performance, and in the meantime lower the number of repeaters and simplify the network. This means lower installation and maintenance costs and higher link reliability. Roughly speaking, it can be said that optical amplification has overcome attenuation limits. This paper presents the use of Raman amplification for gain flattening in an optical communication system.
