TL;DR: In this article, the authors demonstrate 1.01-Pb/s transmission over 52 km with the highest aggregate spectral efficiency of 91.4 b/s/Hz by using low-crosstalk one-ring-structured 12-core fiber.
Proceedings ArticleDOI
New generation optical infrastructure technologies: “EXAT initiative” towards 2020 and beyond
TL;DR: The research effort of most advanced optical infrastructure technologies named "EXAT: Extremely Advanced Transmission" towards the next few decades and beyond are described in this article, enabling well over Peta bit/s per fiber link capacity and Exa-class network throughput.
Journal ArticleDOI
Enhancing optical communications with brand new fibers
TL;DR: The most recent research efforts around the globe launched over the past few years are reviewed with a view to overcome limitations and substantially increase capacity by exploring the last degree of freedom available: the spatial domain.

More than 1000 channel optical frequency chain generation from single supercontinuum source with 12.5 GHz channel spacing
Hidehiko Takara,Takuya Ohara,Kunihiko Mori,K. Sato,Eiichi Yamada,Yasuyuki Inoue,T. Shibata,Masashi Abe,Toshio Morioka,Ken-ichi Sato +9 more
TL;DR: More than 1000 optical frequency channels were generated with 12.5 GHz spacing from a single supercontinuum source in this article, and 600-700 channels for the wavelength range 1512-1580 nm were confirmed to offer SNRs and Q factors sufficient for multi-span 2.5 Gbit/s DWDM transmission.
