The frontiers of optical access networks
2015 International Conference on Optical Network Design and Modeling (ONDM), 2015We report on the state-of-the-art and future prospects and challenges of optical access networks. These networks can be used for various different applications such as fiber-to-the-home (FTTH) but also for backhauling data communications as well as for mobile back- and fronthauling purposes.

Optical access and transport networks
IEEE Communications Magazine, 2012Since OFC/NFOEC '12, the premier global communications industry event of the year, we have been seeing a steady stream of news regarding field trials and implementations of 100 Gb/s optical transport systems in carrier networks. As announced in our May 2012 OCS editorial, global popularity of this topic led us to designate high-speed optical transport ...

Resilient architecture for optical access networks
Photonic Network Communications, 2020This work proposes a resilient wheel-based wavelength-division-multiplexed passive optical network optical access network architecture for backhauling network traffic. This proposed resilient architecture can efficiently support not only the fixed users but also the mobile users in the downstream direction under normal and failure operating scenarios ...

Abstract Access networks have evolved relentlessly over time in diverse directions. For example, PSTN initially provided only landline voice services in the last mile and later offered data-access using dial-up, ISDN, and ADSL technologies.

The role of optical CDMA in access networks
IEEE Communications Magazine, 2002We investigate the possible role of optical CDMA (O-CDMA) in future access networks. We begin with a short review of the O-CDMA technique for those unfamiliar with the technology. Next, we investigate in detail those characteristics of O-CDMA that make it an attractive technology for application in metro access networks: fairness, flexibility ...

Options for future optical access networks
IEEE Communications Magazine, 2006Optical access technology is now standardized, commercially available, and being deployed in some countries. In general, technology continues to develop, and optical access is no exception. New optical access technologies are now being widely reported; the technical trends are WDM, 10 Gb/s, and longer reach/higher splits.

Unauthorized Access Monitoring in Optical Access Networks
2020 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SYNCHROINFO), 2020The article deals with the problem of protecting information from unauthorized access. The results of comparative analysis of methods for information extracting from optical fiber lines are presented. The classification of extraction methods, physical conditions for leak channels formation is given.

IEEE Network, 1996
Both broadcast CATV and switched telephony access networks have evolved, over decades, to deliver their respective services efficiently. But these networks are not necessarily optimal for services that are rapidly emerging. This suggests that the access infrastructure will likely change in the future, driven by demands for new services and the costs of

Hybrid Optical–Wireless Access Networks
Proceedings of the IEEE, 2012Next-generation access networks are expected to provide mobility, large data bandwidth, high quality of service (QoS), and ubiquitous coverage. Hybrid optical-wireless access networks will support these complementary features through high-capacity fiber subnetworks and flexible wireless subnetworks.

Security for FTTx Optical Access Networks
Proceedings. 2006 31st IEEE Conference on Local Computer Networks, 2006Passive Optical Networks (PONs) is the answer to increasing demand on bandwidth and an enabler for Fiber To The x (FTTx) implementation, where x can be Home (FTTH), Curb (FTTC), or Building (FTTB). However, PONs use shared fiber link with Broadcast and Select type of downstream traffic on single wavelength, which makes it vulnerable to eavesdropping ...
