Intra-cavity dispersion-induced performance degradations of dual-RSOA-based self-seeded PON systems

Experiments show that, compared to 10m-long dual-RSOA self-seeded cavities, 1km-long cavity's chromatic dispersions considerably broaden signal spectral widths, increase RINs by 4.8dB, and cause 2.2dB power penalty degradations for 10Gb/s@25km adaptive OOFDM self-seeded PON systems.
