Fiber Capacity Limits With Optimized Ring Constellations
15 October 2009
We calculate theoretical limits to fiber-optic transport capacity under the constraint of requiring the use of concentric multi-ring modulation alphabets. Subject to these conditions we vary ring amplitude ratios and occupation probabilities to determine the capacity-optimized ring constellations. The technique used for fiber transmission calculations accurately captures all fiber nonlinear effects with the accuracy limited only by the noise and signal statistical properties.
