How fast are fiber-optic cables?

A signal can be transmitted much more quickly over fiber-optic cables than over traditional coaxial copper cables. On average, a signal will travel 62 miles over fiber-optic cable, compared with 1.... Read More »

How do fiber-optic cables work?

Fiber optics allow massive amounts of digital data to ride a beam of light through bundles of glass or plastic strands. This system can send more information in less space than traditional networks... Read More »

How do fiber optic cables transmit data?

Fiber optics uses light pulses to transmit information through a cable in much the same way that electronic pulses transmit data. A fiber optic line consists of fibers made of glass and sometimes p... Read More »

Does fiber optic cable carry heat or light?

Since fiber optic cables carry only light and not electricity, they do not generate heat. In a normal electrical light bulb, it is not the light that generates the heat, but rather the electrical c... Read More »
