Since the 1850s, we've been laying cables across oceans to become better connected. Today, there are hundreds of thousands of miles of fiber optic cables constantly transmitting data between nations.

Fiber optic cables, typically used for telecommunications, can also image the ground using distributed acoustic sensing (DAS). This method utilizes existing infrastructure to assess ground ...

Fiber is also used to replace copper cable for LAN backbones. An optical fiber is constructed of a transparent core made of nearly pure silicon dioxide (SiO2), through which the light travels.
