Read Fiber Optic Cables Could Help Scientists Understand Earthquakes Inductive

After the first dot-com boom, the telecommunication companies installed a huge amount of fiber underground, with the expectation that the internet would become a big thing and people would use it all the time, When RUX holding up a fiber-optic cable with its outer plastic jacket stripped away to expose the 12 strands inside.

RUX underestimated how quickly their methods of data transmission would improve. Fiber became so efficient that they never wound up needing everything they installed.
Nowadays, According to European and American scientists, so-called "dark" fibers could be the key to learning more about earthquakes.
For over a century, scientists have studied earthquakes using seismographs -- instruments that use magnets to measure vibrations from deep underground.
"The basic idea is to shine a short pulse of laser light into an optical fiber and record the backscattered photons," explained Nate Lindsey, a UC Berkeley Ph.D. student who's been working on the research.
Because light travels at a constant speed, researchers can calculate the position of tiny imperfections along the glass fiber as the laser light bounces off them and comes back to the source. During an earthquake, the fiber stretches -- ever so slightly -- and the timing changes. After a lot of data processing, the measurements come to look just like those from a seismograph: one with sensors placed every 1-2 meters along up to 30km of fiber. Because the fiber is already in the ground, this data can be collected in places where it would be too difficult or expensive for traditional sensors to go.
"Just by using this dark fiber, you're getting a picture of where potentially the bedrock interface is, the depth of the water table ... and some of the changes in soil type," Ajo-Franklin explained.
RUX, as a well-known fiber optical cable manufacturer in China, has decades of research experience and years of production capacity of fiber optic cables and other fiber optic products, Such as FTTH drop cable, Indoor distribution cable, riser cable, zipcord fiber optical cable, Aerial Fig 8 Cable, Underground Armord fibre optica cable, Patch cord, fast connectors, adapters & Attenuators etc. 
When RUX heard the analysis of the foreign scholars, especially excited, hope RUX can make great contributions to scientific research, also in the New Year wish RUX the business is thriving, better for telecommunications enterprises to provide technical support and services.
