Advances in optical access networks

OFC/NFOEC Technical Digest. Optical Fiber Communication Conference, 2005., 2005
The EPON (Ethernet passive optical network) standard (IEEE 802.3ah) only covers physical and data link layers; the rest is considered out-of-scope. This article explores several interesting research problems brought forward by the EPON architecture, but left out by the standard.

Introduction to Optical Access Networks

2020
Fixed-access networks have had a tremendous impact on society over the last few decades enabling residential broadband services and being a driver for the digitalization of society. With increasing broadband speeds, optical access technologies are playing an increasingly important role for fixed access.

Developments in optical access networks

BT Technology Journal, 2002
Optical fibre access network technology has become more complex over the last few years with bit rates steadily increasing. PON systems are available with bit rates in the range 155 Mbit/s to, currently, 622 Mbit/s. Newly designed systems, both PON and point-to-point, will allow this trend to continue with 2.5 Gbit/s systems becoming practicable in the

Advanced broadband optical access networks

2009 18th Annual Wireless and Optical Communications Conference, 2009
Optical fiber-based access networks are being deployed to address the increasing demand for bandwidth and help to support multiple services. As for the future optical access networks, different technologies have been proposed and under investigations, including WDM-based passive optical networks (WDM-PON), optical coding division multiplexing —based ...

Active Optical Access Networks

2010
In this chapter, active optical access networks (AONs) are examined. AONs are a special type of optical access networks in which the sharing of optical fibers among users is implemented by means of active equipment (as opposed to passive optical networks –PONs– where sharing is achieved by using multiplepassive splitters).

Next Generation Optical Access Networks

Advanced Photonics, 2011
Future optical access networks must support increased rate, reach, split, multi-operator access & wireline / wireless convergence. This paper outlines the role, challenges and breakthroughs of NG technologies including TDM-PON, WDM-PON & TWDM-PON.

Hybrid Optical–Wireless Access Networks

Proceedings of the IEEE, 2012
Next-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.

Optical Access-Metro Networks

2009
The majority of previous research activities to mitigate the first/last mile bottleneck and metro gap were carried out separately from each other. After paving in FTTX networks all the way or close to the end user with optical fiber, the next evolutionary step seems to be the optical integration of fiber-based access and metro networks.

Optical access and transport networks

IEEE Communications Magazine, 2012
Since 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 ...

Optical components in access networks

Optical Society of America Annual Meeting, 1992
The architectural options for optical access networks revolve around either point to point (star) systems or shared access systems (passive optical networks, or PONs). The PON approach has gained acceptance as the most promising for early economic penetration of fiber in the access network.
