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

Reflective Semiconductor Optical Amplifiers in passive optical networks
2009 14th OptoElectronics and Communications Conference, 2009Reflective Semiconductor Optical Amplifiers (RSOAs) offer a cost effective wavelength agnostic transmitter for applications within wavelength division multiplexed passive optical networks (WDM PONs) obviating the need for tuneable or fixed laser sources at customer premises.

On the Capacity of WDM Passive Optical Networks
IEEE Transactions on Communications, 2011To 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, 2008This 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.

Deterministic passive optical networking
Journal of Optical Communications and NetworkingA 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.

A comparison of passive optical network security
SPIE Proceedings, 2009In 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
