Optical TDR can also be used to locate fiber breaks, but since there are perhaps dozens of individual fibers inside a cable that would each have to be scanned, the fact that anything that would ...

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.

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.
