We demonstrate a spatial division multiplexing (SDM) network testbed composed of three nodes connected via 19-core multi-core fibers. Each node is capable of joint spatial circuit switching and joint packet switching to support 10 Tb/s spatial circuit super channels and 1 Tb/s line rate spatial packet super channels. The performance of the proposed hybrid network is evaluated, showing successful co-existence of both systems in the same network to provide high capacity and high granularity services. Finally, we demonstrate an optical channel selection associated with the quality of service requirements on the SDM network testbed.
The introduction of space division multiplexing in optical networks brings new challenges for network protection since the lightpath can span high capacity and transmit data at different rates. In addition, these networks suffer from the fragmentation of the spectrum that hinders contiguity and continuity constraints and, therefore, increases the block. To address these problems, in this paper, we propose the protection algorithm for elastic optical networks with spatial division multiplexing through multipath routing and shared backup paths.
Due to their low cost and improved safety compared to lithium-ion batteries, sodium-ion batteries have attracted worldwide attention in recent decades.
