Present-day networks are being challenged by dramatic increases in data rate demands of emerging applications. New network architectures for streaming/routing large “elephant” transactions will be needed for cost and power efficiencies. This chapter examines a number of possible optical network transport mechanisms: optical packet switching, burst switching, and flow switching and describes the necessary physical layer, routing, and transport layers architectures for these transport mechanisms. Performance comparisons are made based on capacity utilization, scalability, costs, and power consumption. A global-reach network architecture, incorporating optical flow switching, will provide significant lower cost and power consumption for large transactions. This transport mechanism will necessitate physical, media access control, routing, and transport layers and control plane architecture changes over the current Internet architecture and must co-exist with traditional TCP/IP electronic packet switching transport in the same optical network. Scalability in network management and control and session scheduling is identified as the most important driver in the architecture construct. The physical architecture coupled with a matched media access control protocol can help slow down the control plane and still can operate the network with highly dynamic sessions and at high efficiency which is critical for low cost and low power operations. For intra-data center networks when the network bandwidth is not as challenged as a wide area network some form of burst switching can be advantageous if fast light-weight protocols are needed albeit the network must be used at light occupancy for low collision probabilities.

This chapter provides a global network service provider’s view on the technology development and product commercialization of 100-Gb/s for optical transport networks. Optical channel capacity has been growing over the past four decades to address traffic demand growth and will continue this trend for the foreseeable future to meet the ever-increasing bandwidth requirements. In this chapter, optical channels are re-classified into three basic design types. Commercial 100-Gb/s channel development experienced all three types of channel designs before eventually settling on the single carrier PM-QPSK format with coherent detection, which appears to be the optimal design in the industry. A series of 100-Gb/s channel related field trials were performed in service providers’ networks to validate the technical merits as well as business advantages of this new capacity standard before its deployment. Introduction of the 100-Gb/s channel brings new opportunities to boost fiber capacity, accommodate increases in client interface speed rates, lower transmission latency, simplify network management, and speed up the realization of next generation optical add/drop functions.

The transmission of multi-band radio signals through optical fibers has drawn great attention recently for its potential in cellular backhaul networks, mobile cloud computing, and wireless local-area networks. As wireless services and technologies evolve to multi-gigabit radio access networks, their speed is increased but the wireless coverage of a single access point is inevitably reduced dramatically. As a result, the importance of >10GHz radio-over-fiber techniques has been emphasized for the capability of expanding wireless coverage feasibility, and in the meantime reducing system complexity and operation expenditure, especially in the high-speed millimeter-wave regime. In this chapter, we introduce the radio-over-fiber technique and its challenge of handling optical millimeter-wave generation, transmission, and converged multi-band system. By exploring real-world, system implementation and characterization, the unique features and versatile applications of radio-over-fiber technologies are investigated and reviewed to reach next-generation converged optical and wireless access networks.

For many years, the prime drivers behind advances in telecommunications have been the need for increased capacity and reduced cost. But recently, concerns about the rising energy use of telecommunications networks have brought the issue of energy efficiency into the mix, both for equipment vendors and for network operators. In this chapter, we provide an overview of energy consumption in telecommunications networks. We identify the key contributors to energy consumption and identify trends in the growth of energy consumption. We compare the performance of state-of-the-art equipment with theoretical lower bounds on energy consumption and point to opportunities for improving the energy efficiency of core metro and access networks. We show that there is potential for significant improvements in energy efficiency.

This chapter starts by providing some statistics on traffic demand in optical networks and the capacity scaling over time of commercial optical communication systems. Next there is a brief review of the basic results of information theory. We then describe the stochastic nonlinear Schrödinger equation (SNSE), the equation that governs nonlinear propagation in SMFs. This is followed by calculations of nonlinear capacity limit estimates for the SSMF, and advanced fibers with improved transmission characteristics are then presented along with an analytical formula of nonlinear capacity. We then introduce a set of coupled partial differential equations (PDEs) describing nonlinear propagation of polarization-division multiplexed (PDM) signals in SMFs along with nonlinear capacity estimates for these systems. This followed by a focus on multimode fibers (MMFs) and multicore fibers (MCFs). The rest of the chapter then focuses on nonlinear effects in MMFs and MCFs, with an emphasis on MMFs and FMFs. The chapter concludes by reporting experimental observations of two important effects involving nonlinear effects between spatial modes: inter-modal cross-phase modulation (IM-XPM) and inter-modal four-wave mixing (IM-FWM).

We provide on overview of fundamental technologies and recent challenges on extremely higher-order quadrature amplitude modulation (QAM) such as 256–1024 levels, toward the realization of an ultrahigh spectral efficiency approaching the Shannon limit. Key components required for such a higher-order QAM transmission are described in detail, including a coherent light source, an optical phase-locked loop, an IQ modulator, and a digital demodulator. We also present recent demonstrations of single-carrier 1024 QAM, 256 QAM-OFDM, and OTDM-RZ/32 QAM transmissions realized with these fundamental technologies.

Multi-core fiber (MCF) transmission technologies have been widely studied as the simplest form of space-division multiplexing (SDM). Many types of MCFs exist,but the most common is “Uncoupled MCF” where each individual core is assumed to be an independent optical path. The key issue in these systems is how to suppress the inter-core crosstalk and the coupling/de-coupling mechanism. Currently, many MCF varieties, coupling methods, splicing techniques, and transmission schemes have been proposed and demonstrated and despite many of the component technologies still being in the development stage, MCF systems already present the capability for huge transmission capacity. In this chapter, these component technologies and early experimental trials of MCF transmission are reviewed. At first, we provide an overview of medium- to long-haul MCF transmission and theories. Secondly, coupling technologies between MCF-SMF and MCF-MCF are reviewed. Finally, several experimental demonstrations, including transmission exceeding 100Tb/s and over 1000km, are described.

Radio-over-fiber (RoF) link technology has been developed to support multiple wireless signals over optical fiber applications such as mobile backhaul networks and WLANs. Given that conventional wireless networks use packet-switch links between the central office and remote base stations, the cost and complexity of the high-speed wireless networks for data and video transmission increase exponentially while the area of effective coverage decreases. These wireless systems become more inefficient as the data rates and the carrier frequencies required for delivering multi-gigabit wireless services climb higher. However, radio-over-fiber link systems utilizing lightwave to carry multiple analog RF signals through optical fibers can greatly extend the cellular sizes while transparent to the bit rates, modulation formats, and protocols. As a result, the complexity of wireless system to deliver multi-band, multi-gigabit wireless services can be simplified by taking advantages of microwave photonics in optical wireless network design and system integration. The end-to-end RoF systems, from the generation schemes of 1–100 GHz optical wireless signals in the central office to the design of transceivers for base stations and radio access units, are reviewed and investigated in this chapter. Various radio-over-fiber link technologies and the optical wireless interface specifications required to build a converged multi-service, gigabit wireless access network are introduced. The system impairment and its mitigation of radio-over-fiber link transmission will be investigated and analyzed.

This chapter aims to describe the current state of the PON technology, including both “state-of-the-art” systems that are currently under research in the laboratory and “standardized” systems that have been or soon will be described as an industry norm. A short introduction to the PON topic will be given, to set the scene and provide the basic motivation for why PON is so important to fiber access. Then, each of the major technologies will be reviewed, including TDM, Video overlay, WDM, FDM, and Hybrid multiplexing. The focus of each review will be at a system level and will not dive into the details (those will be handled via references to published works). Rather, the intention is to present the wide view of the whole range, so as to compare and contrast them.
