Propagation of broadband photon pairs over deployed telecommunication fibers is used to achieve nonlocal dispersion compensation without the deliberate introduction of negative dispersion. This is made possible by exploiting time-energy entanglement and the positive and negative dispersive properties of the fiber. We demonstrate preservation of photon timing correlations after transmission over two multi-segment 10km spans of deployed fiber and up to 80km of laboratory-based fiber.
