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 ...

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.

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 ...

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 ...

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.

Charting the future of optical access networks: an operator’s perspective [Invited]
Journal of Optical Communications and Networking, 2023When an end customer praises or complains about “Internet,” the chances are the subject of the conversation is specifically the access network. Yet network operators were relatively slow introducing optical technologies into the access segment of data ...

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.

Opportunities for optical access network transceivers beyond OOK [invited]
IEEE\/OSA Journal of Optical Communications and Networking, 2018In response to the ever-growing challenge of using conventional direct-modulation/direct-detection transceivers for upgrading passive optical networks, there has recently been a surge in interest in alternative transceiver technologies. Candidate systems
