Abstract
In this work, an interferometric sensor has been interrogated 290 km away from the
monitoring station, reaching the longest distance in fiber optic sensing up to date. This has been
attained by employing a double-pumped random distributed feedback fiber laser as the light
source for a fiber optic low-coherence interferometry scheme. Additionally, the capability of

In this work, an interferometric sensor has been interrogated 290 km away from the
monitoring station, reaching the longest distance in fiber optic sensing up to date. This has been
attained by employing a double-pumped random distributed feedback fiber laser as the light
source for a fiber optic low-coherence interferometry scheme. Additionally, the capability of
the system to achieve coherence multiplexing for ultra-long range measurements (up to 270
km) has been proved, without presenting crosstalk between the sensors. The use of coherence
multiplexing together with a random distributed feedback fiber laser addresses two of the main
limitations of long-range sensing setups: their limited multiplexing capability and the need to
reach the maximum monitoring distance. [--]
