Conventional fiber-optic networks can operate effective sensors of earthquakes
shaoran2012The California land often shaken by earthquakes, so the experimental station of detecting earthquakes posted here. And, after a year of observations, the developers have concluded it works better than expected. A feature of the new system is that it is based on conventional optical fiber, through which, in large cities come online. In the optical fiber light moving, Bouncing off the walls of the cable, and if this environment were the same and not subject to outside influences, the signal always had the same handwriting.
