Distributed Brillouin measurement in graded index multimode optical fiber
We present distributed Brillouin measurements realized in a commercially available graded-index few mode optical fiber. The measurements were performed using a Brillouin Optical Time Domain Reflectometer instrument coupled with an industrial multiplexer designed for the multimode fiber, enabling the characterization of 15 Hermite-Gaussian modes of the multimode fiber. The low intermodal crosstalk observed allowed for reliable measurements even in the absence of the multiplexer. Preliminary results of temperature Brillouin frequency coefficient are also presented.
