Next generation wavelength division multiplexed passive optical access networks (WDM-PON), employing reflective semiconductor optical amplifiers (RSOAs), can provide a cost effective solution to jointly support both, classic PON services and transparent overlay wireless backhauling. In this approach, the wireless signals are transparently transmitted over the WDMPON, thus creating a virtual dedicated network without incurring into additional network installation and maintenance costs. In this paper, the performance of a WDM-PON transmitting an overlay orthogonal frequency-division multiplexing (OFDM) wireless signal is assessed analytically and experimentally, with relevant system impairments being identified and system design guidelines are provided.
