Abstract
We have developed a long-range Brillouin distributed sensor featuring 100 km measuring distance with 2 meter resolution. To our knowledge, this is the first time that a high-resolution setup reaches the barrier of 100 km measurement range. The key improvements with respect to previous configurations are explained.
