Overview of Raman Amplification in Telecommunications of interest in Raman amplification. By the early part of the 2000s, almost every long-haul (typically between 300 and 800 km) or ultra-long-haul (typically longer than 800 km) fiber-optic transmission system uses Raman amplification. There are some fundamental and technological reasons for the interest in Raman amplifiers that this book explores.

Dispersion-Compensating Fibers for Raman Applications. Normally, a discrete Raman amplifier will contain several kilometers of fiber, adding extra dispersion to the system that must be handled in the overall dispersion management. Dispersion-compensating Raman amplifiers integrate two key functions, dispersion compensation and discrete Raman amplification, into a single component.

Noise due to Fast-Gain Dynamics in semiconductor amplifiers results in a large amount of crosstalk between signal channels, even at high frequencies, and poor system performance. However, the Raman effect in optical fibers is quite weak such that the gain cavity needs to be several kilometers long.
