Paper Abstract

Dispersion management in single mode fiber (SMF) can be accomplished in many ways, though the most widely used approach employs lengths of transport fiber of opposite dispersion characteristics to the principal fiber in the link, usually standard single mode fiber (SSMF). Typically, a 10 to 20km length of dispersion compensating fiber (DCF) is placed before the regenerators inducing negative dispersion to compensate for the positive dispersion accumulated over the 60 to 80km length of the SMF. Analysis and comparison of the pre-compensation scheme and the post-compensation scheme have been done. Due to the interplay between dispersion, nonlinearity, and signal power, the dispersion affects the pulse evolution.
