Abstract
In a passive optical network (PON) architecture compliant with the next-generation PON Stage 2 standard layout, the frequency-division multiplexing (FDM) modulation has been exploited to effectively increase the upstream (US) capacity by overcoming the bandwidth limitation of the reflective semiconductor optical amplifiers (RSOAs) used at the optical network unit (ONU). The intrinsic flexibility offered by the FDM modulation allowed us to properly choose the FDM subcarrier assignment, the modulation format, and the baud rate per each ONU. A rate of 2 Gb/s per ONU has been experimentally demonstrated over a 20 km transmission in an optical distribution network (ODN) with 27 dB losses, and a rate of at least 1 Gb/s per ONU has been obtained after a 43 km standard single-mode fiber in an ODN with 31 dB losses. The preliminary experimentation has been carried out by means of two independent RSOA-based ONUs, sharing the same seed, targeting 32 Gb/s capacity per wavelength and 128 Gb/s overall throughput by means of 4 US wavelength division multiplexed carriers.
