Abstract: We propose and experimentally demonstrate a carrier-reuse, single-feeder, wavelength-division-multiplexed, orthogonal-frequency-division-multiple-access passive optical network (WDM-OFDMA-PON) with colorless direct-detection optical network units and coherent detection optical line terminals. We examine two strategies by adjusting the frequency occupancy and the modulation format of the uplink (UL) and downlink (DL) signals. We investigate the impact of DL signal-to-carrier ratio on performance of both UL and DL via simulations and identify impairments limiting system performance. As a proof of concept, we demonstrate on a single wavelength channel, a realization of each of the two scenarios investigated using orthogonal-frequency-division-multiplexing (OFDM). A quadrature phase-shift keying approach with wide spectrum and narrow guard band achieves 21.6 Gb/s. A 32-ary quadrature amplitude modulation approach with narrow spectrum and wide guard band achieves 14.5 Gb/s and a span of over 80 km.
