Keio Future Photonic Network Open Lab
An open lab at Keio University that freely provides access to cutting-edge optical technologies and promotes exploratory research.

🔷Overview🔷

This lab promotes research and development of advanced optical transmission technologies contributing to a green society, under the Ministry of Internal Affairs and Communications project, “Research and Development of Advanced Optical Transmission Technologies for a Green Society,” Theme II: Large-capacity and highly multiplexed optical access network transmission technologies.
The lab serves as a CoE (Center of Excellence) for optical access and metro technologies toward 2030. As an open laboratory where domestic and international institutions including academics can conduct experiments, it provides functions to foster application expansion, deployment, and open innovation.
It is equipped with 400Gbps optical access systems (initially 100Gbps) including PON/OLT/ONU, and is also planned to support the world’s first hollow-core fiber (a photonic crystal fiber with an air core and structured cladding).
A local 5G experimental station has already been established at the K2 Town Campus for the first time within Keio University, creating an environment that can be utilized by many research groups.
In fiscal year 2024, we plan not only to focus on ultra-multiwavelength access systems, but also to take on the challenge of power-over-fiber (PoF) with IoT applications in mind, while simultaneously initiating research on energy-harvesting IoT systems.
In fiscal year 2025, in collaboration with the University of Texas at Dallas (UTD), we are developing a global open laboratory. The lab will invite academia and industry from Japan and abroad to conduct collaborative research.
To support this, a local 5G network will be deployed to enable collaboration with autonomous driving, AGVs, and robotics, forming the core of the center’s operations.

🔷Next-Generation Access Network Concept🔷

▶Flexible PON: It can provide the optimal bandwidth at high speed with low power consumption, tailored to the user’s desired services and bandwidth requirements. To achieve this, research on new optical transceivers (capable of dynamically adjusting rates and wavelengths) is necessary.

▶Ultra-high split technology: Rather than conventional residential use, it supports a wide range of composite use cases, including sensors, IoT, mobile backhaul, and cloudlet data center access.
