Chapter 1. Modeling, Simulation, Design and Engineering of WDM Systems and Networks: An Introduction

Optical systems and networks have evolved enormously in the last three decades with the creation of next-generation optical components, subsystems, systems, and networks that are now utilized in all aspects of the network structure starting from the in-house/building and access networks, all the way up to the backbone and ultra long-haul infrastructures. This book addresses a variety of issues related to next-generation optical systems and networks, starting from modeling and simulation and then proceeding to design and engineering, enabling the reader to gain an understanding of the latest developments in the ever-expanding field of optical communication systems and networks and of all the open technological and research issues. It presents the state-of-the-art architectures of optical systems and networks and takes a vertical approach to system/network modeling and design, starting from the transmission effects and component level and moving all the way up to the control layer. Analysis is mixed with modeling/simulation and engineering approaches to present the current industry techniques, as well as the research state-of-the-art.

Chapter 4. Semianalytical Models for Network Performance Evaluation

We discuss the linearization and the momentum methods as two complementary approaches for analyzing signal statistics in optical communications systems governed by the nonlinear Schrödinger equation. Based on the linearization, we derive the covariance matrix method that allows us to accurately compute the bit error rates. The momentum method represents an alternative approach for computationally efficient analysis of the amplitude and timing jitter, as well as signal statistics.

Chapter 5. Commercial Optical Communication Software Simulation Tools

System simulation tools can enhance and accelerate user modeling capabilities and provide real field design scenarios using extensive industry specifications. Users of these tools include optical component and equipment manufacturers, system integrators, service providers, as well as government labs and academic institutions. Modeling tools can be used to maximize performance, minimize costs, reduce time-to-market, fast-prototyping, and analyze multiple “what-if” scenarios for optical communication networks. In this chapter we briefly review three system level modeling tools that are commercially available, namely, OptSim from RSoft Design Group (http://​www.​rsoftdesign.​com), VPItransmissionMaker Optical Systems from VPIphotonics, a division of VPIsystems (http://​www.​vpiphotonics.​com), and OptiSystem from Optiwave Systems Corporation (http://​www.​optiwave.​com). This is not an attempt to compare the tools and no recommendation should be implied from the order or content of the material presented, but rather a presentation of what resources are available to the scientific community.

IMPLEMENTATIONS

Chapter 6. Optical Interconnects

We present an overview of optical interconnection systems by first defining the need and requirements for such systems and then presenting and reviewing the state of the art of the necessary components and processes, as well as the different technologies and architectures involved in their design. The design simplifications achieved by using optical interconnects compared to electrical solutions are also examined. Nevertheless, the view presented here is that the two worlds of optical and electrical interconnects can converge and successfully lead to solutions that are even beyond our imagination at this point in time.

Chapter 7. Short Range (in-building) Systems and Networks: A Chance for Plastic Optical Fibers

In this chapter the deployment of plastic optical fibers in short-range (in-building) networks is examined. The application is evaluated in the context of the problem of modeling optical power propagation through the fiber when it is deployed in peculiar environments such as those inside a house. A fast and versatile matrix method is developed to model optical power transmission throughout the fiber. This method is flexible in incorporating the effects of localized disturbances over transmission and compact in facilitating integration in commercial software packages.

Chapter 9. Fiber to the Home Through Passive Optical Networks

This chapter presents a comprehensive overview of current deployed and novel proposed protocols and subsystem architectures for passive optical networks. Emphasis is given to link layer techniques that allow resource sharing emphasizing bandwidth utilization or so-called dynamic bandwidth allocation techniques. In the transport layer, methods for ONU remote-seeding and their limitations are described as they allow for cost reduction, which is of paramount importance in the access area.

Chapter 10. Coherent Optical Communication Systems

The rapid evolution of long-haul optical communications systems, witnessed in the last five years, is due to the gradual adoption of spectrally efficient, multilevel modulation formats, in conjunction with polarization division multiplexing (PDM) and coherent intradyne detection assisted by digital signal processing (DSP). The objective of this tutorial chapter is to briefly review the operating principles of state-of-the-art long-haul coherent optical communications systems. Due to limitations in space, it focuses mainly on coherent optical systems using quadrature phase-shift keying (QPSK) modulation.

LOGICAL LAYER

Chapter 12. Impairment-Aware Optical Networking: A Survey

In optical networks the effect of physical layer impairments can play an important role in the routing and wavelength assignment decisions that are taken in the control layer. Furthermore, as networks evolve to support more bandwidth-intensive applications, and as rich multimedia and real-time services become more popular, next-generation networks are expected to support traffic that will be heterogeneous in nature with both unicast and multicast applications. In this chapter we investigate the problems of routing and wavelength assignment in transparent optical networks that support unicast and multicast applications, while taking into consideration the physical layer impairments during the provisioning of each application.

Chapter 13. Provisioning and Survivability in Multi-Domain Optical Networks

Modern wireline infrastructures have morphed into a complex interconnection of distributed decentralized domains, as delineated by ownership, location, and technology type. These developments have prompted the need for advanced control plane solutions to achieve services/applications provisioning across multiple-possibly heterogeneous-domains with guaranteed quality of service (QoS) and reliability. As a result, multiple efforts are underway to address these concerns, including standardization initiatives as well as research studies in key topic areas, i.e., multi-domain routing, distributed path computation, survivability, and others. Along these lines, this chapter presents a detailed survey of some of these contributions, with a particular emphasis on those in the multi-domain optical networking area.

Globales Erdungssystem in urbanen Kabelnetzen

Bedingt durch die Altersstruktur vieler Kabelverteilnetze mit der damit verbundenen verminderten Isolationsfestigkeit oder durch fortschreitenden Kabelausbau ist es immer häufiger erforderlich, anstelle der Resonanz-Sternpunktserdung alternative Konzepte für die Sternpunktsbehandlung umzusetzen. Die damit verbundenen Fehlerortungskonzepte bzw. die Erhöhung der Restströme im Erdschlussfall führen jedoch aufgrund der hohen Fehlerströme zu neuen Anforderungen an die Erdungs- und Fehlerstromrückleitungs-Systeme. Lesen Sie hier über die Auswirkung von leitfähigen Strukturen auf die Stromaufteilung sowie die Potentialverhältnisse in urbanen Kabelnetzen bei stromstarken Erdschlüssen. Jetzt gratis downloaden!
