“…Different upgrading technologies are being proposed by industry, standard bodies and research institutions, mostly defined by their point-to-multi-point multiplexing form. Architectures are typically based on tree topology, with one or two splitting stages, sharing the maximum length of feeder fiber and optical line terminal ports; ring and bus topologies have also been demonstrated for protection and load balancing [120,121].…”

Lightwave communications is a necessity for the information age. Optical links provide enormous bandwidth, and the optical fiber is the only medium that can meet the modern society's needs for transporting massive amounts of data over long distances. Applications range from global highcapacity networks, which constitute the backbone of the internet, to the massively parallel interconnects that provide data connectivity inside datacenters and supercomputers. Optical communications is a diverse and rapidly changing field, where experts in photonics, communications, electronics, and signal processing work side by side to meet the ever-increasing demands for higher capacity, lower cost, and lower energy consumption, while adapting the system design to novel services and technologies. Due to the interdisciplinary nature of this rich research field, Journal of Optics has invited 16 researchers, each a world-leading expert in their respective subfields, to contribute a section to this invited review article, summarizing their views on state-of-the-art and future developments in optical communications.

With the aim of using a single laser in single fiber splitter-based Passive Optical Networks (PON) with coherent homodyne transceivers, we apply wavelength shifting in an ultradense Wavelength Division Multiplexing (ud-WDM) scheme. The studied architecture is based on IQ modulator operating in Carrier-Suppressed Single-Sideband (CS-SSB). In this configuration, a single laser feeds both the coherent homodyne receiver, and the transmitter, simplifying the wavelength management in the PON. The modulator carries out both data modulation and wavelength shifting. In this study, a bit rate of 4 Gbit/s in QPSK is used to test several roll-off factors and channel spacing configurations. The results sh ow that power budget gains of 18 dB are achievable with a channel spacing equal to only the symbol rate.

Abstract-New technologies for ultra-dense WDM-PON (udWDM-PON), enabled by coherent techniques and low cost devices, are developed for an efficient utilization of the optical spectrum, revealing that the "Wavelength-to-the-User" concept can be feasible. In this work, an udWDM-PON with only 6.25 GHz channel spacing is implemented with conventional DFB lasers, for a splitter-based PON infrastructure with 256 ONUs. The results of the analysis of udWDM access network architecture with respect to their associated complexity, cost and migration scenarios, exhibit the potential for higher aggregate throughput, higher split ratios and node consolidation, when compared to competing technologies.Index Terms-Fiber optical communications, fiber-to-thehome, access networks, PON, WDM.
