An adaptive dispersion compensation system that also achieves optical
amplification by inducing Raman amplification effects in dispersion
compensating fiber. This amplification/chromatic dispersion compensation
architecture may be applied, e.g., at the end of an all-optical link, or
an intermediate points along the link. By varying the length of
dispersion compensating fiber used and the pump power, one may
accommodate a wide range of dispersion compensation requirements as
determined in the field. This scheme also provides all of the advantages
typically provided by the use of Raman amplification.
