Optoelectronic method for inline compensation of XPM in long-haul optical links

We propose an optoelectronic subsystem for inline compensation of XPM-induced phase noise in long-haul optical links. Based on intensity-dependent phase rotation, these compensators are used to suppress XPM on a span-by-span basis. Using a 7-channel hybrid WDM system as a test case, our simulations...

Description
Summary:We propose an optoelectronic subsystem for inline compensation of XPM-induced phase noise in long-haul optical links. Based on intensity-dependent phase rotation, these compensators are used to suppress XPM on a span-by-span basis. Using a 7-channel hybrid WDM system as a test case, our simulations show that this technique is effective at suppressing XPM in dispersion managed and unmanaged links for various transmission distances.
