OFDMA-PON for future generation metro-access networks

An approach to the implementation of an extended reach orthogonal frequency division multiple access passive optical network (OFDMA-PON) is described for deployment in the future metro-access network. The high performance network which can be operated at 100 Gbps over spans of up to 100 km provides for a variety of desirable characteristics including enhanced resource allocation flexibility, scalability and potentially lower equipment cost/complexity while also supporting multi-wavelength operation. In addition, the OFDMA-PON enables the convergence of the optical infrastructures with standard wireless services providing for the integration of wired and wireless technologies to form a hybrid access network to support ubiquitous broadband services. Next generation wireless backhauling over the OFDMA-PON is also discussed with solutions being provided to facilitate this mechanism.
