TL;DR: This article reports the work on next generation transponders for optical networks carried out within the last few years, highlighting advantages, economics, and complexity.

TL;DR: An SDN based network planning framework utilizing machine-learning techniques and a network-scale monitoring database is implemented over an optical field-trial testbed comprised of 436.4km fibre to demonstrate the spectral efficiency utilising probabilistic-shaping BVT based on link performance prediction.

TL;DR: RDNA explores the programmability of residues number system as a fundamental concept to define a minimalist forwarding model for core nodes, which achieves 600 ns switching latency per hop with virtually no jitter at core nodes and sub-millisecond failure recovery time.

TL;DR: In this article, the authors look into network planning issues for synthetic MCF-based SDM networks implemented through programmable ROADMs and show that significant savings in switching modules and energy consumption can be achieved.

TL;DR: This work proposes a novel architecture for an elastic optical interface by combining a variable bitrate transceiver, paired with an elastic aggregation stage, with software-defined control, and reports a real-time field-programmable-gate-array-based prototype that delivers flexible transport frames to be sent with a polarization-division multiplexed quadrature phase-shift keying modulation format.
