Further examples also provide a power and data adapter that can provide power and data to a mobile computing device using a single cable ... fiber optic technology it has in mind is actually Light ...

DSL, satellite, fiber ... and cable can be chalked up to the way they transmit information. Fiber-optic technology uses small, flexible strands of glass to transmit the information as light.

A flexible fiber optic cable with a vacuously hollow interior ... those photons don't actually travel at the speed of light. Rather, the medium in which those pulses travel -- the optical fiber ...

The standard line is that fiber optic networks transfer data at the speed of light. But in reality ... problem is getting the signal to follow the cable through bends and curves.
