    Next-generation access systems will have to provide bandwidths in excess of 100 Mb/s per residential customer, in conjunction with high customer count and high maximum reach. Potential systems solutions include several variants of WDM-PONs. These systems, however, differ significantly in their cost (capital expenditures) and energy consumption potential. We compare several WDM-PON concepts, includ... View full abstract»

    To rapidly meet increasing traffic demands from subscribers, the IEEE 802.3av task force was charged to study the 10G-EPON system to increase the data rate to 10 times the line rate of 1G-EPON. With the increase of the line rate, the energy consumption of 10G-EPON increases accordingly. Achieving low energy consumption with 10G-EPON has attracted broad research attention from both academia and ind... View full abstract»

    In this article we present a new scheme to support multirate and multi-quality-of-service transmission in passive optical networks based on a hybrid wavelength-division multiplexing/optical code-division multiplexing scheme. The idea is to use multilength variable-weight optical orthogonal codes as signature sequences of a hybrid WDM/OCDM system. To provide the requested classes of service, the co... View full abstract»

    As PONs carry increasing amounts of data, issues relating to their protection and maintenance are becoming crucial. In-service monitoring of the PON's fiber infrastructure is a powerful enabling tool to those ends, and a number of techniques have been proposed, some of them based on optical time-domain reflectometry. In this work we address the required features of PON monitoring techniques and re... View full abstract»

    Coordinated multipoint or cooperative MIMO is one of the promising concepts to improve cell edge user data rate and spectral efficiency beyond what is possible with MIMOOFDM in the first versions of LTE or WiMAX. Interference can be exploited or mitigated by cooperation between sectors or different sites. Significant gains can be shown for both the uplink and downlink. A range of technical challen...
