TLDR
In this paper, the authors used a spatial light modulator based Brillouin OTDR to measure the mode coupling between LP01 and higher order modes with a spatial resolution of 50 m.Abstract:
We report non-disruptive measurement of distributed mode coupling in a five mode fiber using a spatial light modulator based Brillouin OTDR. Mode coupling between LP01 mode and higher order modes is obtained with a spatial resolution of 50 m.read more

Capacity Limits of Optical Fiber Networks
TL;DR: In this article, the capacity limit of fiber-optic communication systems (or fiber channels?) is estimated based on information theory and the relationship between the commonly used signal to noise ratio and the optical signal-to-noise ratio is discussed.

Complete discrimination of strain and temperature using Brillouin frequency shift and birefringence in a polarization-maintaining fiber
TL;DR: A novel method that realizes simultaneous and completely discriminative measurement of strain and temperature using one piece of Panda-type polarization-maintaining fibre is presented and it is found that the Brillouin frequency shift and the birefringence have the same signs for strain-dependence but opposite signs for temperature-Dependence.
