Newly structured Hollow-Core Fiber and its open innovation field for Power over fiber, Radio over fiber and ultra-low latency application (Invited talk)

For the next generation network, ultra-low latency network must be use for smart society vehicle. For this purpose, we have built a campus network using hollow-core fiber, aiming for a breakthrough from devices that will meet the ultra-low delay requirements of Beyond 5G. Hollow-core fibers have a air hole in the core and have succeeded in trapping light in the core. Using the characteristics of this fiber, we will report on the current experimental results regarding the possibilities of multi-branch access, ultra-multi-wavelength networks, radio over fiber (RoF), and power over fiber (PWoF). We also opened the Keio Future Optical Network Open Research Center to make these available for open use.
