“…The line system comprises 12 spans of 62-km Corning ® Vascade ® EX3000 fiber with 0.16-dB/km loss. Each span is padded by a VOA in order to realize a span loss of ~16.5 dB and to operate our 744-km straight-line system in a lower-OSNR regime pertinent to the targeted massively parallel submarine application [1]- [5]. Since launch powers are low and fiber nonlinearities are negligible (as quantitatively verified below), padding at the beginning of a span is equally permissible as padding at the end.…”

“…ASSIVE spatial parallelism has been shown to maximize the capacity and to minimize the cost/bit of submarine optical cables, which, in contrast to terrestrial transmission systems, are constrained by a fixed amount of electrical supply power per cable [1]- [4]: The capacity of a massively parallel system with a supply power constraint is given by [3], [5]…”

“…Finally, in the core network, traffic is further aggregated to be transported over long-haul links. Here, innovation is faster, with the data rate per card doubling every 3-4 years [44]. In software-configurable optical networks, services are dynamically adapted through SDN.…”

“…One possible way to expand the design of distributed sensing methods is to target future telecommunication fiber deployments. At the moment, the ability to transport data traffic is lagging under the ever increasing demands of consumers, limited by the gain band of in-line amplifiers and the available power budget of telecommunication fibers [23]. The current techno-economic landscape suggests that the next iteration of telecommunication fibers will expand capacity through space-division multiplexing (SDM) tech-niques [24] (either in the form of few-mode [25] or multicore fibers [26]) in order to remain economically competitive [23,27].…”
