Internet of Things Approach for Creating Value in VariousFields▼Abstract

The Internet of Things (IoT) is expected to create high value services in various fields. We believe that theera in which IoT is fully utilized will have requirements different from those of the past for information andtelecommunications networks. In this article, the influence of the new IoT era on networks and information
processing is described, along with the resulting requirements. The NTT laboratories’ efforts and assumed
usage scenarios are also introduced. These Feature Articles are based on lectures given during workshops
at the Tsukuba Forum 2017 held in October 2017.

▼Abstract

Space-division multiplexing using multicore fiber (MCF) is considered to be one of the most promisingtechnologies for breaking the capacity limit of traditional single-mode fibers and advancing fiber optic
communication systems. For transport networks to utilize the capacity of MCF efficiently, it is essential toconsider inter-core crosstalk (XT) in provisioning optical paths. We developed an MCF transport network
testbed and used it to demonstrate our optical path configuration scheme, in which a software-defined
networking controller configures programmable transponders that include a beyond-100G digital signal
processor that factors in XT.
