TL;DR: This tutorial paper surveys the photonic switching hardware solutions in support of evolving optical networking solutions enabling capacity expansion based on the proposed approaches and presents the first cost comparisons, to the knowledge, of the different approaches in an effort to quantify such tradeoffs.

TL;DR: In this paper, the authors evaluate the advantages of using the extra dimension introduced by space-division multiplexing (SDM) for dynamic bandwidth-allocation purposes in a flexible optical network, with an emphasis on the spectral efficiency (SE)/reach tradeoff for different multiline-rate scenarios, created either by changing the number of sub-channels (Sb-Ch), or by employing different modulation formats.

TL;DR: In this paper, the spectral and spatial switching granularity of a spatial division multiplexing (SDM) network are compared in terms of spectral utilization, data occupancy, and network switching infrastructure cost.

TL;DR: This work compares SDM joint and independent switching strategies in a planning scenario involving a European backbone network and finds joint switching can achieve cost savings of 40-50% with a performance similar to that of independent switching.

TL;DR: Different SDM network realizations in terms of average spectrum utilization and the number of in-operation transceivers operating over different modulation formats showcasing the benefits and drawbacks of SDM networks relying on different transmission media are compared.
