FBMC for directly modulated passive optical networks (PON)
2015 International Topical Meeting on Microwave Photonics (MWP), 2015In this paper the transmission of FBMC based services for PON's using direct modulation of low-cost Discrete Mode lasers is studied. The FBMC system is composed of 21 overlapping subcarriers each modulated by 16-QAM. We experimentally study the performance of such a directly modulated FBMC system in back-to-back and fibre transmission scenarios up to ...

Storage area network extension over passive optical networks (S-PONS)
IEEE Communications Magazine, 2008After 9/11 and the accidental failure of the power grid in North America in 2003, storage area network (SAN) extension has emerged as critical to ensuring business continuity. However, SAN extension encounters challenges in the access network, including scalability problems, cost challenges, bandwidth bottlenecks and low throughput. In this article, we

Survivability models for radio-over-fiber passive optical networks (RoF-PON)/PON
2011 seventh International Computer Engineering Conference (ICENCO'2011), 2011In this paper, we will propose some models for PON/RoF-PON combines a number of ideas used before in the research papers, the ITU-U recommendations and also a number of novel models. We compare between those proposed models by using the Expected Survivability Function; a simple and intelligent tool to evaluate network survivability.

Capacity and delay analysis in Passive Optical Networks (PONs) - A review
International Journal of Advances in Computing and Information Technology, 2012The dramatic increase of internet users and development of new high volume internet applications has a profound impact on design of next generation passive optical network (NG-PON). Today, most of the available networks are quite busy networks and as the number of nodes increases in the network, the communication over the network also increases.

Sleep assistive dynamic bandwidth assignment scheme for passive optical network (PON)
Photonic Network Communications, 2018In passive optical network (PON), in addition to efficient bandwidth management, a dynamic bandwidth assignment (DBA) scheme can also enhance the energy efficiency performance of the optical networks units (ONUs) during sleep mode. A few such green DBA schemes have been proposed in literature for EPON, however, ITU compliant PONs have not got attention.
