Giga Ethernet Free-Space Passive Optical Networks

Fiber and Integrated Optics, 2008
Fully passive optical networks with wavelength division multiplexing capabilities will open the access network to the real broad band. Integration with optical wireless is a further step to add low-cost characteristics with high bandwidth capabilities.

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.

Optical Testing for Passive Optical Networks

OFC/NFOEC 2008 - 2008 Conference on Optical Fiber Communication/National Fiber Optic Engineers Conference, 2008
This paper reviews the demand for and the current status of PON optical diagnostics. Special focus is given to methods of optical testing that use capabilities that are incorporated into the transmission equipment itself.

Passive optical network architectures with optical loopbacks

2005 IEEE LEOS Annual Meeting Conference Proceedings, 2005
This paper summarizes some of the important deployment capabilities of PONs that are facilitated by optical loopbacks in the passive outside plant. The optical loopbacks route upstream traffic back to all ONUs where this information is used in conjunction with additional optical and electronic components in the customer premises, to control upstream ...

Long Reach Passive Optical Networks

LEOS 2007 - IEEE Lasers and Electro-Optics Society Annual Meeting Conference Proceedings, 2007
We discuss recent progress in the development of optically amplified, long reach passive optical networks, which aim to significantly reduce network complexity and cost by integrating metro and access into a single, all-optical communication system.

Multi-uplink passive optical networks

2007 Conference on Lasers and Electro-Optics (CLEO), 2007
We propose to use multiple uplinks in passive optical networks (PONs) to increase the optical transmission power from users to central office. The requirement of the PON receiver at the central office is discussed.

GMPLS-based passive optical network

SPIE Proceedings, 2005
The significance of Generalized Multi-protocol Label Switching (GMPLS) has been proven by its significant adoption in ASON. In recent years GMPLS has become the most global solution to provide intelligent optical resource configuration through not only devices that perform packet switching, but also devices that perform switching in the time ...

Few-Mode Passive Optical Network

Asia Communications and Photonics Conference 2015, 2015
Single-mode splitters lack conservation of degrees of freedom and when they are used in PONs, they introduce combining losses. The arrival of few-mode optics can eliminate the combining loss and thus improve PON size.

Synchronization for passive optical networks

Journal of Lightwave Technology, 1995
There is widespread interest in the passive optical network as a solution for a future fiber in the loop network. This paper addresses the problem of synchronization at the line termination of a passive optical network that uses high-speed time division multiple access.
