We are talking thousands of kilometers, like across oceans.

Actually not that different from an electrical signal does through copper. Because this is light traveling through a nearly transparent medium, it moves at approximately 200,000 km/s. The Layers protect both the integrity of the signal as well as the structure of the glass. Nowadays, fiber optic cables are made of a highly transparent flexible glass core that is wrapped in a series of layers. Instead of waves traveling through metal. in the 1970s changed the game completely by allowing the use of light bursts to carry a signal. Optical fiber cable invented by Corning Inc.

One is that copper is much less expensive per unit distance than fiber. In fact, copper only has two main advantages. Also, these waveforms degrade very quickly as the distance between devices increases. Hence limiting its maximum data capacity. The problem with copper is that even higher bandwidth coaxial cables can carry only a small number of waveforms. And converting the patterns in the waveform into an analog or digital signal.Ī device that modulates and demodulates is called a modem.
Copper wires use the movement of electrons to carry signals by modulating a waveform at one end then demodulating it at the other end.
This is what makes it so great for carrying the power to your home. Related Article: What is Fibre To The Home (FTTH)? Copper Cables #Ĭopper is highly conductive.
