This paper proposes a novel wavelength division multiplexing-orthogonal frequency multiple access (WDM-OFDMA) union passive optical network (uni-PON) architecture with dynamic resource allocation and variable rate access. It can offer an infrastructure with different access solutions. According to the quality of service (QoS) requirement of different services, the optical local terminal (OLT) can dynamically assign different resources as well as the access rates to different services. An experiment has been demonstrated with 4 wavelengths achieving combined signal at 109.92-Gb/s. A physical-layer adaptive algorithm is employed for the resource allocation and variable rate access. The different services with different resource allocations and variable access rates are also demonstrated in the experiment.
