The Hollow Core Fiber (HCF) has attracted the attention as an innovative optical fiber that has the potential to break through limitations of conventional optical fibers in terms of low latency, low loss, low nonlinearity, environmental resistance and so on. We have succeeded ahead of the world in achieving in making both Single Mode (SM) and low loss HCF, in connectorizing, and cabling of the HCF with our unique structure. The results of these developments were reported in Furukawa Electric Review No. 52. Subsequently, we have conducted reliability tests, optimization of fusion splicing conditions, cable installation tests, and application evaluation experiments in order to further promote practical applications of the HCF. We are reporting on the results of these investigations here.
