Twisted Pair Cable − It contains two insulated copper wired twisted together in the spiral. It can be shielded or unshielded.
Following are the two types of twisted-pair cables
Let us explain the difference between Twisted Pair Cable, Co-axial Cable and Optical Fibre Cable.
|Twisted Pair Cable||Co-axial Cable||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.|
|A short circuit between the two conductors is possible.||A short circuit between the two conductors is possible.||A short circuit is not possible.|
|It is cheapest||It is moderately expensive.||It is expensive.|
|It can support low data rates.||It can be relatively high data rates.||It is very high data rates.|
|Power loss due to conduction and radiation||Power loss due to conduction||Power loss due to absorption, scattering dispersion and bending.|
|Node capacity per segment is 2.||Node capacity per segment is 30 to 100.||Node capacity per segment is 2.|
|Attenuation is very high.||Attenuation is low.||Attenuation is very low.|
|Installation is easy.||Installation is relatively easy.||Installation is complicated.|
