Abstract
End-to-end real-time optical orthogonal frequency-division multiple-access
(OOFDMA) passive optical networks (PONs) with adaptive dynamic bandwidth allocation
(DBA) and colorless optical network units (ONUs) are experimentally demonstrated, for
the first time, at aggregated 10.375 Gb/s over 26.4 km standard single-mode fibers based
on intensity modulation and direct detection. The colorless ONU operation for several
representative wavelengths across the C-band is successfully achieved by utilizing
cost-effective reflective semiconductor optical amplifier intensity modulators, whose
narrow signal modulation bandwidths are fully exploited through adaptability of the
OOFDM transceivers and adaptive DBA. Taking into account the optical beat interference
effect, the impact of wavelength spacing between adjacent ONUs on the upstream OOFDMA
PON performance is experimentally investigated, based on which the minimum achievable
ONU wavelength spacing is identified.
