Abstract

This paper describes the development of a hybrid multiplexing network for optical fiber sensors using a multiwavelength lasing long-range structure and the simultaneous utilization of an OTDR on the same network to interrogate displacement sensors based on microbenders. With this design, simultaneous interrogation of displacement and temperature was carried out 50 km away from the system header.
