What Is a Coaxial Output?

by Colin Cronin

Coaxial output connects a coaxial cable to a device or terminal with a coaxial input. They are used in a variety of communication and electronic networks, from transmitting radio frequencies to connecting DVD players to an audio system.

Design

A coaxial cable is designed as a copper core conductor surrounded by a flexible and tubular insulation as well as a conducting shield. The current travels in the space between the inner tube and outer wires.

Function

Coaxial output produces data that is interpreted by the input. As a frequency transmission network, output produces signals for Internet use, cable television and radio broadcasts. In the realm of consumer electronics, coaxial output (often referred to as digital coaxial output) sends audio data interpreted by a matching input which translates that data into sound.

Advantage

Because the signal transmits only in the space between the inner and outer conductors, coaxial cables can run alongside other metal objects without fear of power loss. The outer shield protects the signal transmission from electromagnetic interference.
