[WA3-1]Spatial Channel Network (SCN): Concept, Architecture and Enabling Technologies
○Masahiko Jinno
It is widely recognized that the capacity of commercial optical transmission systems is rapidly approaching the theoretical limit for conventional single-mode fibers (SMFs). To accommodate the ever-increasing Internet traffic, massive parallelism in the spatial domain is required in both link and network technologies. Among the various types of spatial-division multiplexing (SDM) fibers proposed, uncoupled multicore fiber (MCF) is considered promising due to its compatibility with conventional SMF-based technologies. Recently, the mass production of uncoupled 2-core fiber has begun, and its introduction into commercial submarine cable systems has been announced. The recently proposed spatial channel network (SCN) architecture offers hierarchical spatial bypassing and spectral grooming, which are advantageous in the SDM era for (i) reducing total node costs while maintaining high spectral efficiency, (ii) extending optical reach for signals that spatially bypass the overlying wavelength-division multiplexing layer, and (iii) reducing intra-node fiber wiring compared to SXCs using conventional SMF-based fiber switches. A key component for realizing SCNs is the spatial cross-connect (SXC), which consists of MCF-based optical switching devices such as core-selective switches and multicore erbium-doped fiber amplifiers. This tutorial reviews the architecture and benefits of SCNs, recent advances in enabling key technologies, and SCN networking demonstrations.
Bio: Masahiko Jinno received his B.E. and M.E. degrees in electronics engineering from Kanazawa University in 1984 and 1986, respectively, and his Ph.D. in engineering from Osaka University in 1995. He is currently a Professor at Kagawa University, Japan, focusing on architectures and enabling technologies for ultra-high-capacity optical networks. Before joining Kagawa University in 2012, he was a Senior Research Engineer and Supervisor at NTT Network Innovation Laboratories, where he pioneered research on elastic optical networks (EONs). From 1993 to 1994, he was a guest scientist at NIST, USA. Dr. Jinno has authored over 200 papers on optical signal processing, WDM systems, ROADMs, GMPLS, EONs, and spatial channel networks (SCNs). He is a Fellow of IEEE and IEICE and a Senior Member of Optica. His awards include the Best Paper Awards from the 1997, 1998, 2007, and 2019 Optoelectronics and Communications Conferences (OECC), the IEICE Achievement Award, and the IEEE Communications Society Asia-Pacific Outstanding Paper Award.
