WDM-PON colourless transmitters based on RSOA self-seeding (SS) proved to be compact self-tuning transceivers up to 10 Gb/s. We employ frequency-division multiplexing (FDM) with different subcarrier modulations to effectively exploit a 2-GHz limited O-band RSOA in a SS architecture, achieving, for the first time to the best of our knowledge, 12-Gb/s transmission over 10-km SSMF. Due to O-band low chromatic dispersion, propagation distance is only limited by the power budget, which determines the sub-bands signal to noise ratio, reducing equalization effectiveness. The paper presents sub-bands allocation, measured constellation diagrams and BERs, which demonstrate the promising capability of the combination of FDM and RSOA SS to obtain beyond 10-Gb/s self-tuning WDM PON transmitters.

Abstract
WDM-PON colourless transmitters based on RSOA self-seeding (SS) proved to be compact self-tuning transceivers up to 10 Gb/s. We employ frequency-division multiplexing (FDM) with different subcarrier modulations to effectively exploit a 2-GHz limited O-band RSOA in a SS architecture, achieving, for the first time to the best of our knowledge, 12-Gb/s transmission over 10-km SSMF. Due to O-band low chromatic dispersion, propagation distance is only limited by the power budget, which determines the sub-bands signal to noise ratio, reducing equalization effectiveness. The paper presents sub-bands allocation, measured constellation diagrams and BERs, which demonstrate the promising capability of the combination of FDM and RSOA SS to obtain beyond 10-Gb/s self-tuning WDM PON transmitters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
