The present invention includes analyzing an optical signal at a first location in a system (502), determining if an eye of the signal has a desired shape (504), automatically adjusting a dispersion amount of the signal at a second location if needed (506), providing feedback in response to the adjusted signal at the first location (508), and automatically readjusting the dispersion of the second location based on the feedback (510). This method and system provide considerable time and raises the reliability. It can be used to provide a continuous range of dispersion compensation to paritcular locations in the network or to the network as a whole, and to store information in a database to be used to produce dispersion maps for the network. It also provides the ability to dial in dispersion for changing fiber characteristics and pre-tuning switching of wavelengths from one system to another. Finally, it avoids extraordinary expense by allowing the approximation of the installed fiber dispersion without requiring field measurements.
