In this work, a remote fiber optic switch powered by light is demonstrated experimentally. This fiber optic switch is powered by a photovoltaic power converter illuminated by a Raman laser. The switch can operate at distances up to 100 km. This switch is used to develop a remote resilient fiber Bragg grating (FBG) multiplexing network interrogated by a commercial FBG interrogator. In the proposed set-up the switch selects the branch of the FBG network located 50 km away from the interrogation unit in order to enable a two-way interrogation path for each sensor to prevent connection failures or fiber breakages.

Variable gain Current Conveyors have been proposed to allow control of the value on fixed resistors. In this paper, procedures will be described, taking into account the stability of different configurations when a practical CCII- is applied. Correction circuits will modify the control range. Frequency response and transients are shown.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
