Evolving Greenfield Passive Optical Networks [PDF]

BT Technology Journal, 2003
We investigate applying an evolutionary algorithm (EA) to the design of a passive optical network (PON). We use three techniques to improve the performance. Firstly, to reduce the risk of sub-optimal convergence, we use a novel genetic encoding. Secondly, we combine the EA with a heuristic to guide the optimisation. Thirdly, we investigate various ways

Deterministic passive optical networking

Journal of Optical Communications and Networking
A time-division-multiplexed (TDM) passive optical network (PON) that behaves like multiple point-to-point (P2P) links can support applications with stringent timing requirements while also maintaining the cost benefits of the point-to-multipoint (P2MP) topology.

On the Capacity of WDM Passive Optical Networks

IEEE Transactions on Communications, 2011
To lower costs, WDM PONs may share the usage of wavelengths, transmitters, and receivers among ONUs, instead of dedicating the transmission between OLT and each ONU with one individual wavelength and one individual pair of transmitter and receiver.

Practical Deployment of Passive Optical Networks

IEEE Communications Magazine, 2008
This article describes several real deployments of passive optical networks (PONs, the most common form of fiber to the home, FTTH) in several parts of the world, some with incumbent providers, some with other entities. The networks and service models are described, along with initial experiences with providing service.

A comparison of passive optical network security

SPIE Proceedings, 2009
In this paper, a comparison of the physical security aspects of a time division multiplexed (TDM) passive optical network (PON) and a proposed wavelength hopping passive optical network (WH-PON) is presented. Simulated results of an eavesdropping attempt in both networks are presented. The introduction of a WH-PON will demonstrate how physical layer

WDM Ethernet passive optical networks

IEEE Communications Magazine, 2006
WDM EPONs not only allow for cautious pay-as-you-grow upgrades of single-channel TDM EPONs but also avoid linearly increasing polling cycle times for an increasing number of ONUS. In this article, we first provide a comprehensive overview of the state of the art of TDM EPONs and recently reported dynamic bandwidth allocation algorithms, including ...
