That's a description of wire pairs.

Coaxial cable is a single conductor in the center of a
long conducting cylinder.

Optical fiber is not wire at all.  It's a thin strand of glass,
through which a modulated light beam is passed, often
for miles.

A Microwave System is also not a wire.  It's a radio link that can
carry high-speed data, between two points that are anywhere
from 100 yards to 100 miles apart. 
(I know this because I make my living designing, installing, and
troubleshooting Microwave Systems.)

Aform of energy that is reflected or emitted from objects in the form of electrical and magnetic waves that can travel through space. there are many forms of  electromagnetic  energy including gamma rays, x rays, ultraviolet radiation, visible light, infrared radiation, microwaves and radio waves.
