TL;DR: The goal here is to explain some of the design issues surrounding FSO systems and to provide sufficient information to allow potential users to evaluate the suitability of a specific FSO system for a particular application.
Abstract: Given the relative newness of free-space optics (FSO) technology in commercial applications, few standardized metrics exist for comparing the performance of different systems. Our goal here is to explain some of the design issues surrounding FSO systems and to provide sufficient information to allow potential users to evaluate the suitability of a specific FSO system for a particular application. In addition, we attempt to define the realistic performance limitations of FSO on the basis of existing technology and also to set reasonable expectations with regard to atmospheric conditions.

TL;DR: Incorporating wavelength-division multiplexing (WDM) in a PON allows one to support much higher bandwidth compared to the standard PON, which operates in the traditional copper-based networks.
Abstract: Feature Issue on
Optical Access Networks (OAN) The passive optical network (PON) is
an optical fiber based network architecture, which can provide much higher bandwidth
in the access network compared to traditional copper-based networks. Incorporating
wavelength-division multiplexing (WDM) in a PON allows one to support much higher
bandwidth compared to the standard PON, which operates in the "single-wavelength
mode" where one wavelength is used for upstream transmission and a separate one is
used for downstream transmission. We present a comprehensive review of various
aspects of WDM-PONs proposed in the literature. This includes enabling device
technologies for WDM-PONs and network architectures, as well as the corresponding
protocols and services that may be deployed on a WDM-PON. The WDM-PON will become a
revolutionary and scalable broadband access technology that will provide high
bandwidth to end users.

TL;DR: This work investigates how the Multipoint Control Protocol—an EPON transmission arbitration mechanism—can be combined with a strict (exhaustive) priority scheduling that is a default scheduling algorithm specified in the Institute of Electrical and Electronics Engineers (IEEE) 802.1D standard.
Abstract: Ethernet passive optical networks (EPONs) are being designed to deliver multiple services and applications, such as voice communications, standard and high-definition video (STV and HDTV), video conferencing (interactive video), real-time and near-real-time transactions, and data traffic. To support these applications with their diverse requirements, EPONs need to have class-of-service (CoS) mechanisms built in. Here we investigate how the Multipoint Control Protocol (MPCP)—an EPON transmission arbitration mechanism—can be combined with a strict (exhaustive) priority scheduling that is a default scheduling algorithm specified in the Institute of Electrical and Electronics Engineers (IEEE) 802.1D standard. Specifically, packet delays for different classes of traffic are analyzed. We find that the queuing delay for lower-priority classes increases when the network load decreases (a phenomenon we call light-load penalty). We also suggest and analyze two different optimization schemes that eliminate the light-load penalty.

TL;DR: In this paper, a review of the work carried out within the EU Network of Excellence ISIS on radio-over-fiber systems for the support of current and emerging wireless networks is reviewed.
Abstract: Some of the work carried out within the EU Network of Excellence ISIS on radio-over-fiber systems for the support of current and emerging wireless networks is reviewed. Direct laser modulation and externally modulated links have been investigated, and demonstrations of single-mode fiber and multimode fiber systems are presented. The wireless networks studied range from personal area networks (such as ZigBee and ultrawideband) through wireless local area networks to wireless metropolitan area networks (WiMAX) and third-generation mobile communications systems. The performance of the radio-over-fiber transmission is referenced to the specifications of the relevant standard, protocol operation is verified, and complete network demonstrations are implemented.

TL;DR: In 1998, Ramaswami and Sivaraja did a great job of assembling into a single book the main physics and network concepts required for serious professionals in this new field of optical networking.
Abstract: In 1998, Ramaswami and Sivaraja, in the first edition of Optical Networks: A Practical Perspective, did a great job of assembling into a single book the main physics and network concepts required for serious professionals in this new field. Now, four years later in the second edition, the book has been updated with the more recent advances in the field, and the more promising optical networking technologies are emphasized.
