Single and double distributed optical amplifier fiber bus networks with wavelength-division multiplexing for photonic sensors

Two different optical fiber bus networks are compared and demonstrated experimentally as means of gathering information from four wavelength-division-multiplexed photonic sensors. Both topologies include distributed amplification, which allows one to overcome the limitation in the maximum number of sensors that can be multiplexed in a single structure. Results obtained with a dual-bus topology are compared with those achieved with a single-bus network

Topologías ópticas en bus y doble con amplificación distribuida para la multiplexación en longitud de onda de sensores fotónicos

In this paper a comparison between a single and double optical fiber bus is made. These structures are used to provide wavelength-division-multiplexing of four photonic sensors, and include distributed amplification in order to counterbalance the losses induced by the distribution architecture
