Abstract The Covid-19 pandemic showed forcefully the fundamental importance broadband data communication and internet has in our society. Optical communications forms undisputable backbone of this critical infrastructure, it is supported by an interdisciplinary research community striving to improve develop further. Since first ‘Roadmap optical communications’ was published 2016, field seen significant progress all areas, time ripe for update status. area become increasingly diverse, covering physics materials science, high-speed electronics photonics, signal processing coding, systems networks. This roadmap describes state-of-the-art future outlooks field. article divided into 20 sections on selected each written a leading expert that area. are thematically grouped four parts with 4–6 each, covering, respectively, hardware, algorithms, networks systems. Each section current status, challenges, development needed meet said challenges their As whole, provides comprehensive unprecedented overview contemporary research, should be essential reading researchers at any level active

Multi-band optical communication presents a promising avenue for the significant enhancement of fiber-optic transmission capacity without incurring additional costs related to new cable deployment via utilization bandwidth beyond established C&L bands. However, big challenge in its field implementation lies high cost and suboptimal performance amplifiers, stemming from underdeveloped state rare-earth-doped amplifier technologies these Fiber-optic parametric amplifiers provide an alternative wideband amplification, yet their low power efficiency limits practical use field. In this paper, we study hybrid that combines excellent with broadband wavelength conversion capability amplifiers. It uses converters shift signals between S- L-bands, amplifying them L-band erbium-doped fiber amplifier, converting back S-band. We experimentally demonstrate such S-band characterize 16-QAM input signals, evaluate four-wave-mixing-induced crosstalk. This approach paves way scalable expansion bands waiting advancements technology.

Data rates in optical networks have grown exponentially recent decades and are expected to grow beyond the fundamental limits of current standard single-mode fiber networks. As such, novel transmission technologies required sustain this growth, space-division multiplexing provides most promising candidate scale capacity a way that is also cost-effective. For fabrication deployment, it highly beneficial use fibers with cladding diameter. Here we demonstrate petabit-per-second-class data using approaches spatial whilst minimizing signal processing complexity. This done by designing fabricating low-loss 19-core multi-core randomly-coupled cores, diameter, supporting wideband wavelength-division multiplexed signal. The resulting rate 1.7 petabit/s highest reported amongst diameter approximately more than an order magnitude higher supported currently deployed fibers, paving for next-generation ultra-fast
