Telephones, Internet, Utilities, the possibilities are endless!
Fiber optics work through strands of glass that are as thin as hair. Fiber optics are not a new technology, and have been used commercially for 25 years. Fiber optics are much more efficient in transmitting compared to a copper wire. Fiber optics cost about 1% of the price it takes to transmit a telephone conversation through a copper wire. They can also transmit much farther and much more information. They are also immune to interference form electromagnetic radiation, making them more reliable.
How do Fiber Optics work?
Fiber optics are made up of a light-carrying center surrounded by a reflective insulator, trapping the light in the core. Information from one end of a transmission is translated into a light transmission, and sent down the optics. On the receiving end, the light is read and converted back to electrical information and appropriated for a certain communication application. This light used is infrared, light invisible and at too high of a wavelength for the human eye to detect.
