Guide on Twisted Pair Cabling
What is a Twisted Pair Cable?
Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of improving electromagnetic compatibility. It is called 'twisted pair' due to the twisted design which helps to reduce interference and crosstalk.
Importance
The twisted-pair cable is vital because it's extensively used in telecommunication networks due to its high capacity and reliability. It also offers low production cost, flexibility, and ease in set up. Additionally, it assists in eliminating electromagnetic interference.
How It Works?
It works by transmitting data through differential signaling system, where each wire carries an equal and opposite signal. The receiving device notes the potential difference between the two signals rather than referencing to a singular grounded signal source. This arrangement helps in dismissing efficiently the interference caused by electromagnetic waves.
