The new research shows that certain cables can be converted into an array of sensors rather than just one.
Each optical fiber span acted as a sensor, with up to 12 sensors implemented along the cable.
Moreover, the research suggests that this method could potentially be used for detecting tsunamis.
We spoke to Giuseppe Marra, Principal Research Scientist, NPL, about the new technique.
Is it possible, in theory, to do triangulation with the cables?
Can the cable be used to transfer the data it collects at the same time?
Yes, data traffic can be present on the other channels of the same fiber.
Or can it only be used as sensors?
