Abstract

An amplified optical fiber double ring network for the wavelength division multiplexing (WDM) of fiber Bragg grating (FBG) sensors is demonstrated experimentally. The network is inherently resilient to fiber failures due to the simultaneous interrogation of all the sensors using both rings. Furthermore, power transparency at the rings is obtained by means of Raman amplification. We optimize the performance of the network with the launched pump power that shows low levels of amplifiers' noise. We also demonstrate how the topology allows the received powers from the sensors to be equalized.
