Investigation of 10-Gb/s RSOA-based upstream transmission in WDM-PONs utilizing optical filtering and electronic equalization (original) (raw)

This study investigates the upstream transmission capabilities of reflective semiconductor optical amplifiers (RSOAs) in wavelength-division multiplexed passive optical networks (WDM-PONs) at a rate of 10 Gb/s. The authors explore the benefits of combining offset optical filtering with electronic decision-feedback equalization (DFE) to enhance performance and extend transmission distances. The findings reveal significant improvements in transmission efficiency and overall network performance, positioning RSOA technology as a viable solution for future generation PONs.
