چکیده
D to the steady growth in demand for bandwidth, the days when optical fiber was viewed as having unlimited capacity have come to an end. Dispersion, noise, and nonlinearities pose substantial channel impairments that need to be overcome. As a result, over the last decade, signal processing has emerged as a key technology to the advancement of low-cost, high-data rate optical communication systems. The unrelenting progress of semiconductor technology exemplified by Moore’s Law provides an efficient platform for implementing signal processing techniques in the electrical domain leading to what is known as electronic dispersion compensation (EDC). In this article, we provide an overview of some of the driving factors that limit the performance of optical links and highlight some of the potential opportunities for the signal processing community to make substantial contributions.

The common and traditional method for dispersion compensation in optical domain is concatenating the transmit optical fiber by a compensating optical fiber having high-negative dispersion coefficient. In this paper, we take an opposite direction and show how an optical fiber with high-positive dispersion coefficient can also be used for dispersion compensation. Our optical dispersion compensati...
