Difference between Twisted Pair Cable, Co-axial Cable and Optical Fibre Cable

Computer NetworkNetworkOperating System

Twisted Pair Cable − It contains two insulated copper wired twisted together in the spiral. It can be shielded or unshielded.

Types of Twisted Pair Cables

Following are the two types of twisted-pair cables

  • UTP (Unshielded Twisted Pair) − In this pair of wires are twisted together in spiral form and unshielded. These are enclosed in a plastic cover. It is very cheap and easy to install.
  • STP (Shielded Twisted Pair) − A metal foil or braided mesh shields each insulated twisted pair. This mesh is also known as a metal shield.
  • oaxial Cables − It consists of two concentric conductors divided by a dielectric substantial. The external conductor is a metallic braid and can be used for shielding. The co-axial cable can contain one or more co-axial pairs.
  • Optical Fibre Cable − It includes an inner glass core surrounded by a glass cladding with a lower refractive index. Digital signals are sent in the structure of the intensity-modulated light signal, trapped in the glass core.

Let us explain the difference between Twisted Pair Cable, Co-axial Cable and Optical Fibre Cable.

Transmission of signals takes place in the electrical structure over the conflicting metallic wires.Transmission of signals takes place in the electrical structure over the inner conductor of the cable.Signal transmission takes place in an optical structure over glass fibre.
Noise immunity is low. Hence more distortion.Higher noise immunity than the twisted pair cable because of the presence of a shielding conductor.Higher noise immunity as the light rays are unaffected by the electrical noise.
It can be affected due to the external magnetic field.It can be less affected due to the external magnetic field.It is not affected by the external magnetic field.
