Resumen
This work experimentally demonstrates a long-range optical
fiber sensing network for the multiplexing of fiber sensors based on
photonic crystal fibers. Specifically, six photonic crystal fiber sensors
which are based on a Sagnac interferometer that includes a suspended-core
fiber have been used. These sensors offer a high sensitivity for microdisplacement

This work experimentally demonstrates a long-range optical
fiber sensing network for the multiplexing of fiber sensors based on
photonic crystal fibers. Specifically, six photonic crystal fiber sensors
which are based on a Sagnac interferometer that includes a suspended-core
fiber have been used. These sensors offer a high sensitivity for microdisplacement
measurements. The fiber sensor network presents a ladder
structure and its operation mode is based on a fiber ring laser which
combines Raman and Erbium doped fiber amplification. Thus, we show the
first demonstration of photonic crystal fiber sensors for remote
measurement applications up to 75 km. [--]
