Abstract
The creation and development of optical amplifiers has provided significant increases in information capacity in applications ranging from ultra-long undersea links to short links in access networks. This chapter describes the three main optical amplifier types, which are semiconductor optical amplifiers, active fiber or doped-fiber amplifiers, and Raman amplifiers. The topics include noise effects generated in the amplification process, the concept of optical signal-to-noise ratio and its relation to bit-error rate, the operation and use of optical amplifiers based on the Raman scattering mechanism, and wideband optical amplifiers that operate over several wavelength bands simultaneously.
