This article serves as an introductory paper, highlighting the state of the art in fiber-optic transmission systems, pointing to capacity scalability issues, and laying out various capacity scalability options.
By M. Shtaif, C. Antonelli, A. Mecozzi, and X. Chen
This article reviews fiber-optic capacity scaling from an information-theoretic perspective, including the difficulties imposed by the nonlinear nature of fiber-optic transmission.
By T. Kobayashi, J. Cho, M. Lamponi, G. de Valicourt, and C. R. Doer
This article addresses hardware and digital signal processing aspects of modern coherent optical transponders, which have revolutionized the optical communications industry over the past decade and have let commercial optical communication systems closely approach their fundamental limits.
By C. Xie and B. Zhang
This article reviews data center interconnect (DCI) solutions, highlighting hyperscale data center network architectures and requirements, as well as the differences between DCI optical networks and traditional optical carrier networks.
By A. Lord, S. J. Savory, M. Tornatore, and A. Mitra
This article focuses on optimizing wavelength routing around the network, maximizing the benefits arising from fine-control coherent digital signal processing with increasingly accurate real-time monitoring, and the deployment of multiband and multifiber connectivity to cope with exponentially increasing traffic demands to support broadband access and 5G wireless applications.

This article reviews the state of the art in optical fiber cabling and deployment technologies. Modern high-density optical fiber cables can carry thousands of optical fiber strands and hence represent a massively parallel transmission medium, suitable for the massive spatial parallelism that will be needed to scale fiber-optic network capacity.
By T. Matsui, P. L. Pondillo, and K. Nakajima
This article explores the integration of high fiber-count optical cables using multicore optical fibers to realize even higher degrees of spatial parallelism in the future than what can be achieved today.
By T. Hayashi, T. Sakamoto, Y. Yamada, R. Ryf, R.-J. Essiambre, N. Fontaine, M. Mazur, H. Chen, and T. Hasegawa
This article considers an even higher density spatially parallel integration technique that allows for random coupling between the cores of multicore fibers.

This article reviews the third advanced category of space-division multiplexing fibers, which use the coupled waveguide modes of few-mode fibers in conjunction with multiple-input–multiple-output (MIMO) digital signal processing to achieve the highest spatial information density.
By N. K. Fontaine, J. Carpenter, S. Gross, S. Leon-Saval, Y. Jung, D. J. Richardson, and R. Amezcua-Correa
This article reviews the mode-shaping technologies needed to perform mode-division multiplexing on few-mode fibers and discusses implementations and tradeoffs of four different techniques: multiplane light conversion, fused fiber devices, 3-D waveguides in glass, and free-space imaging systems.
By D. M. Marom, Y. Miyamoto, D. T. Neilson, and I. Tomkos
This article examines the capacity scaling requirements of optical networks from a switching perspective that leverage both spectral and spatial degrees of freedom.
