Abstract
Hollow core fibers (HCF) are innovative optical fibers having the potential to break the limits of conventional optical fibers. Examples of innovation are ultra-low loss potential, ultra-low nonlinearity, resistance against harsh conditions, and long interaction lengths with gases confined to the core. In addition, ultra-low latency characteristics have attracted much attention in recent years, particularly amongst financial trading communication systems. For the first time in the world, we have succeeded in developing a high-performance HCF with practical single mode (SM) properties realized by a resonant couple phenomenon, to apply the HCF in the low latency transmission. Furthermore, we have successfully developed HCF connectors and HCF cables to realize the actual low latency transmissions. These development results will be reported.
