Fiber Optic Cable
How it works:
Fiber optics use light rather than electricity to transmit data. In a fiber optic system, electricity is converted into light by a LED (Light-Emitting Diode) or laser and sent down a run of fiber optic cabling. While in the cable, the light bounces off an inner metallic shield called cladding. This cladding keeps the light contained along the fiber optic strand. On the other end of the fiber optic …

Other advantages of fiber optic cable over copper include:
Greater distance-You can run fiber as far as several kilometers. Low attenuation-The light signals meet little resistance, so data can travel farther.
Security-Taps in fiber optic cable are easy to detect. If tapped, the cable leaks light, causing the entire system to fail.
Greater bandwidth-Fiber can carry more data than copper. Immunity-Fiber optics are immune to interference.
