Power over fiber using Hollow-core fiber and its application on IoT-ONU (Invited talk)

Newly structured fiber called Hollow-Core Fiber (HCF) had been equipped into the campus for power over fiber (PWoF) access network. In Keio university’s open lab, we constructed HCF network among four building. HCF transfers the high power optical signal through the air core not glass core materials. Therefore, ultra high-power transmission having maximum 1,000 times larger which can apply to energy transmission (i.e. PWoF). And also high-linearity can realize optical analog signal transmission without degradation called analog radio over fiber. This paper also describes an automatic power off Internet of Things optical network unit for remote cameras application in the Keio university future optical network open research center. These technologies will be key to a reliable and smart beyond 5G society
