Abstract

In this work, a remote powered by light fiber optic switch is experimentally demonstrated. This fiber optic switch is powered by a photovoltaic power converter illuminated by a Raman laser working at distances up to 50 km. This switch is used to develop a remote resilient FBG multiplexing network interrogated by a commercial FBG interrogator. In the proposed set-up the switch selects the branch of the FBG network 50 km away in order to enable a two-way interrogation path for each sensor to prevent connection failures.
