"In the first part of our round-up of the Dallas meeting of the Innovative Optical and Wireless Network (IOWN) project's Global Forum conference in October 2025, we looked at the technological development of the association's all-photonics network (APN) - and the continued work in essentially "moving from electronics to photons", as a representative of one of its key member companies insisted its mission boils down to."
"One of the most important developments over the past year was using the APN to support a theatre performance that synchronised live and virtual performers in Japan and Taiwan, running over a network that was over 3,000km long. In addition to validating a very important use case, the Cho Kabuki project also saw the APN being at the heart of a digital twin,"
"NTT's Masahisa Kawashima, IOWN technology director and head of the technology working group at the IOWN Global Forum, says plans also include demonstrating commercial operability of the APN and defining a new functional architecture for artificial intelligence (AI) computing platforms using co-packaged optics and optical circuit switches. The agile deployment of optical fibres is seen as essential for forthcoming 6G networks. IOWN APN provides a virtualisation layer on top of physical fibre infrastructure."
An all-photonics network (APN) demonstrated low-latency, long-distance synchronization by supporting a theatre performance that linked live and virtual performers across Japan and Taiwan over a 3,000 km network. The Cho Kabuki project placed the APN at the center of a digital twin, enabling digitization and manipulation of performance characters while preserving synchronization. Plans include demonstrating APN commercial operability and defining AI computing platform architectures using co-packaged optics and optical circuit switches. Agile optical fibre deployment will support forthcoming 6G networks. The APN provides a virtualization layer over physical fibre, allowing multiple mobile operators to share infrastructure and reduce availability and cost issues.
