How The Moon Impacts Subsea Communication Cables
Here we report, for the first time, on cable length variations in the sub-meter range that depend on water pressure generated by tidal variations.
In contrast to the two aforementioned implementations, the cable is not impacted by any kind of abrupt sea floor motions. However, changes in local water pressure cause cable length changes that are detectable with an ultra-stable phase meter. In contrast to commonly held views, subsea cables diverge from the ‘loose tube’ model that suggests a forceless bearing on the fibers. Our observations indicate a strong coupling between the cable jacket and the sheathed fiber.
