(NG) PONs (í µí±–) provide increased data rates, split ratios, wavelengths counts, and fiber lengths, as well as (í µí±–í µí±–) allow for all-optical integration of access and metro networks. In this paper we provide a comprehensive probabilistic analysis of the capacity (maximum mean packet throughput) and packet delay of subnetworks that can be used to(More)
fiber provides an unprecedented band-width potential that is far in excess of any other known transmission medium and offers significantly longer ranges without requiring any active devices. Optical fiber has some further advantageous properties such as longevity and low maintenance costs which will eventually render fiber the medium of choice in wired(More)
—A plethora of enabling optical and wireless technologies have been emerging that can be used to build future-proof bimodal fiber-wireless (FiWi) broadband access networks. After overviewing key enabling radio-over-fiber (RoF) and radio-and-fiber (R&F) technologies and briefly surveying the state of the art of FiWi networks, we introduce an Ethernet-based(More)
Passive optical networks (PONs) are currently evolving into next-generation PONs (NG-PONs) which aim at achieving higher data rates, wavelength channel counts, number of optical network units (ONUs), and extended coverage than their conventional counterparts. Due to the increased number of stages and ONUs, NG-PONs face significant challenges to provide the(More)
—Optical and wireless network technologies are expected to converge in the near to midterm, giving rise to bimodal fiber-wireless (FiWi) broadband access networks. In triple-play (voice, video, and data) service scenarios for such FiWi access networks, video traffic will likely dominate due to the widely predicted increase in video network services and the(More)
The evolution of broadband access networks toward bi-modal fiber-wireless (FiWi) access networks, described in this book, may be viewed as the endgame of broadband access. After discussing the economic impact of broad-band access and current worldwide deployment statistics, all the major legacy wireline and wireless broadband access technologies are(More)
—Future bimodal fiber-wireless (FiWi) access-metro networks may deploy both radio-over-fiber (RoF) and radio-and-fiber (R&F) technologies. RoF networks are rapidly becoming mature, but they fall short of interworking with distributed wireless MAC protocols such as DCF in widely deployed IEEE 802.11 WLANs. While R&F networks are able to avoid this limitation(More)
MAC enhancements of emerging high-throughput WLANs are considered and a novel FiWi network architecture is introduced that integrates next-generation WLAN-based WMN and EPON in a pay-as-you-grow manner while providing backward compatibility with a legacy infrastructure and protecting previous investments. To investigate the performance of FiWi networks, the(More)
