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 chapte...

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.
Wavelength-division-multiplexed passive optical network (WDM PON) has long been considered as an ultimate solution for the future optical access network capable of providing practically unlimited bandwidth to each subscriber. On the other hand, it is still considered to be too expensive for the massive deployment. To solve this problem and meet the ever-increasing demand for bandwidth, there have been numerous efforts to improve the competitiveness of WDM PON. This chapter reviews the current status and future direction of these WDM PON technologies. We first review various colorless light sources, which are critical for the cost-effective implementation of the optical network units (ONUs), and several representative network architectures proposed for WDM PONs. We then review the recent research activities for the realization of high-speed (>10Gb/s) and long-reach WDM PONs. Various fault-monitoring and protection techniques are also reviewed as they can be increasingly important in the future high-capacity WDM PONs.

At the beginning of an exciting new era in optical communications, we review fundamentals as well as practical experimental aspects of MIMO-SDM: we discuss the importance of selectively addressing all modes of a coupled-mode SDM channel at transmitter and receiver in order to achieve reliable capacity gains and show that reasonable levels of mode-dependent loss (MDL) are acceptable without much loss of channel capacity. We then introduce MIMO-DSP techniques as an extension of familiar algorithms used in polarization-division multiplexed (PDM) digital coherent receivers and discuss their functionality and scalability. Finally, we review the design of mode multiplexers (MMUXs) that allow for the mapping of the individual transmission signals onto an orthogonal basis of waveguide mode, and discuss their performance in experimental demonstrations.
The increasingly important role of Internet-based, “cloud” service delivery is motivating the evolution of the Internet to a flatter hierarchy of more densely interconnecting networks that shall cost-effectively scale to Zettabytes of bandwidth with improved operational efficiency, under increased traffic variability, and forecast unpredictability. This chapter reviews the implications of this evolution in its underlying metro regional and core transport network architectures, and evaluates the most important innovations in photonics, optical transport, routing, and traffic engineering technologies enabling it. Most notably, 1) a new generation of coherent DWDM systems with more than 2 b/s/Hz spectral efficiency is scaling the existing fiber infrastructure, albeit at a significantly higher proportion, typically more than 50%, of the total transport network cost, while 2) the convergence of IP/MPLS with flexible DWDM promises the most cost-efficient transport evolution, in open architectures that combine advancements in photonics, routing, multi-layer control-plane and management coordination, with interoperability, to improve operation, automate provisioning and restoration, and may optimize network utilization.
The deployment of Reconfigurable Optical Add/Drop Multiplexers (ROADMs) is gradually transforming a transport layer made of point-to-point optical links into a highly-interconnected, reconfigurable photonic mesh. To date, the widespread use of ROADMs has been driven by the cost savings and operational simplicity they provide to quasi-static networks (i.e. networks in which new connections are frequently set up, but rarely taken down). However, new applications exploiting the ROADMs’ ability to dynamically reconfigure a photonic mesh network are now being investigated. In this chapter we review the attributes and limitations of today’s ROADMs and other node hardware, and survey proposals for future improvements, including colorless, non-directional, and contentionless add/drop ports. Applications of reconfigurable networks are also discussed, with emphasis on the backbone network of a major communications service provider (carrier). Finally, we assess which of these new developments are most likely to bring added value in the near-term and long-term future.
