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.

An overview of passive optical networks

Signals, Circuits and Systems, 2003. SCS 2003. International Symposium on, 2003
This paper gives an overview of past and recent developments of Passive Optical Networks (PON's). Such networks currently receive a lot of intention as a means to relieve the so-called last-mile bottleneck in today's broadband networks using optical fiber technology.

Network coding in next-generation passive optical networks

IEEE Communications Magazine, 2011
As the emerging access architecture, NGPONs feature enhanced PON configurations, metro-access integration, and bimodal fiberwireless (FiWi) networks. The moving landscape of NG-PONs provides opportunities for applying novel and promising technologies such as network coding (NC).

Passive optical network security

2021
With Ethernet now emerging as the protocol of choice for carrying IP traffic in metro and access networks, EPON has emerged as a potential optimized architecture for fiber to the building and fiber to the home. The tremendous Internet traffic growth has confirmed that the telecommunications backbone is moving aggressively from a time division ...

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 ...

Green Passive Optical Networks

2012
The future sees a clear trend of data rate increase in both wireless and wireline broadband access. These access networks may experience a dramatic increase of energy consumption in provisioning higher bandwidth as well as for other reasons [8, 28, 61]. For example, to guarantee a sufficient signal-to-noise ratio (SNR) at the receiver side for accurate

Integrity of optical splitters in passive optical networks

Proceedings of 5th Conference on Optical Hybrid Access Networks, 1993
From an examination of test data available from manufacturers, and from results of British Telecom (BT) testing of a range of device types and technologies, BT now has confidence that splitters will be available with sufficient reliability for mass passive optical network (PON) deployment.

Ethernet Passive Optical Networks

2005
Recently, Ethernet Passive Optical Networks (EPONs) have received a great amount of interest as a promising cost-effective solution for next-generation high-speed access networks. This is confirmed by the formation of several fora and working groups that contribute to their development, namely the EPON Forum (http://www.

Optical transceivers for passive optical networks (PON)

2006 Optical Fiber Communication Conference and the National Fiber Optic Engineers Conference, 2006
Optical transceivers used for the passive optical networks (PON) are bi-directional devices that use different wavelengths to transmit and receive signals between the optical line terminal (OLT) at the central office and the optical network units (ONUs) at the end users' premises over a single fiber.
