Effects of chromatic dispersion and self-phase modulation in multihop multirate WDM rings

When compared to first generation and single-hop optical networks, multihop and multirate (M&M) networks have the advantage of significantly reducing network cost under a variety of wavelength-to-terminal cost ratios. This letter investigates how fiber chromatic dispersion and self-phase modulation may affect such cost reduction in M&M wavelength-division-multiplexing rings.
