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.

Extended-Reach Passive Optical Networks

Advanced Photonics, 2011
We review several techniques to extend the reach of PON beyond 60 km utilizing a repeater at the remote node and distributed Raman amplification. We also discuss practical deployment issues and economics of extended-reach PON.

Free Space Passive Optical Network

2018
This paper proposes free space passive optical network (FSPON) as a potential candidate of high data rate access network based on optical wireless transmission. FSPON could be considered for indoor as well as outdoor deployments. Pending the progress in FSO range, it is appropriate for short range communication network.
