This document is a report on the results of the implementation of a PoC listed in the PoC reference document “Open APN Architecture PoC Document”, which is being discussed in the OAF TF of the IONW Global Forum. The PoC described in this report is based on the section 2.5 “Connection case of fiber sensing with APNG” in the reference document “Open APN Architecture PoC Reference“. For the fiber sensing architecture for implementing fiber sensing in APN defined by “IOWN Global Forum Fiber Sensing for Open APN”, we use of APN-G as a switching function of a sensing fiber where APN-G is prepared in APN and shared with communication service. This PoC will verify if this APN-G can be used for fiber sensing. This report shows the PoC of some possible connection between APN-G and fiber sensing. However, the specifications of APN as a whole, including APN-G, are still under discussion, and the implementation model of fiber sensing will be updated as it evolves, and multiple technical PoCs will likely be required.
