TL;DR: In this paper, a wideband SOA is used for amplification of both downstream signals from G-PON and 10G PON access networks, and BER measurements showed a performance of 42dB on optical budget but also pointed out requirements on the SOA to improve this performance.
Abstract: A wide-band SOA is used for amplification of both downstream signals from G-PON and 10G-PON access networks. BER measurements showed a performance of 42dB on optical budget but also pointed out requirements on the SOA to improve this performance.

TL;DR: Experimental results show that the proposed WDM-PON is capable of providing triple play services in the access network.
Abstract: We demonstrate a novel WDM passive optical network (WDM-PON), which delivers data as well as video services to the end users through the employment of subcarrier modulation at the optical line terminal (OLT) and parallel signal detection (PSD) at the optical network unit (ONU). Experimental results show that the proposed WDM-PON is capable of providing triple play services in the access network.

21 Sep 2000TL;DR: In this paper, an optical network, which may be an all-optical network, including passive wavelength routers, is described, and methods for implementing such networks as well as different router configurations are also disclosed.
Abstract: An optical network, which may be an all-optical network, including passive wavelength routers is described. Methods for implementing such networks as well as different router configurations which may be used in optical networks are also disclosed. The routing functionality in the all-optical network can be done in the optical domain without switching elements at the nodes. This is achieved by routers which are passive and preferably operative to route wavelength bands. A mesh can be used as the network configuration. The optical networks described can be used to facilitate the transmission of higher network protocols, such as internet protocol (IP) packets or ATM-cells, purely in the optical domain.

TL;DR: This article discusses and clarifies the issues and technologies for the next-generation energy efficient optical access network from the viewpoints of its mid-term upgrade and long-term evolution.
Abstract: This article discusses and clarifies the issues and technologies for the next-generation energy efficient optical access network from the viewpoints of its mid-term upgrade and long-term evolution. For reducing the total power consumption in the mid-term upgrade to 10-gigabit access, it is necessary to optimize the network configuration as well as the usage of various technologies while avoiding any service degradation in the next-generation broadband services. In the long-term evolution, wavelength routing will play a key role by drastically decreasing the total power consumption of the access network.

TL;DR: In this article, the authors investigate how to obtain the best compromise between harnessing the main benefits of next-generation optical interfaces, while keeping the complexity of the underlying system at a reasonable level.
Abstract: Next-generation elastic optical interfaces will support a wide range of line rates and modulation formats. Such transmission schemes enable doubling of the channel capacity at the expense of a lower reach, whereas a flexible DWDM grid supports the transport of multiple optical signals within a single frequency slot by packing them closely, thus saving spectral resources. The resulting multitude of options on the line side provides network planners the capability to derive the most suitable one for each individual path inside the network. However, planning and operational complexity should not be overlooked, since aspects such as added spectrum fragmentation can hamper the expected network improvements. This paper investigates how to obtain the best compromise between harnessing the main benefits of next-generation optical interfaces, while keeping the complexity of the underlying system at a reasonable level. In particular, we define a novel network spectral efficiency (SE) metric that enables, on one hand, to highlight the relevance of supporting a flexible grid to improve SE and, on the other hand, to demonstrate that the grid granularity can be based on coarser 50 GHz increments without major penalties. The effectiveness of this parameter has been verified by considering two reference network topologies. Finally, the paper also discusses how future optical interface technology developments will shape network design.
