In Guided media transmission using twisted pair, the twisting of cables is done:
  • a)
    To avoid the cross talk between adjacent pairs
  • b)
    To increase the bandwidth for transmission
  • c)
    To avoid the physical damage to the wires
  • d)
    All of the above
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
In Guided media transmission using twisted pair, the twisting of cable...
  • A number of these pairs are bundled together into a cable by wrapping them in a tough protective sheath
  • Over longer distances, cables may contain hundreds of pairs
  • The twisting tends to decrease the crosstalk interference between adjacent pairs in a cable
  • Neighbouring pairs in a bundle typically have somewhat different twist lengths to reduce the crosstalk interference

Twisting of Cables in Twisted Pair Guided Media Transmission

Twisting of cables in twisted pair guided media transmission is done primarily to avoid the cross talk between adjacent pairs. Cross talk is the unwanted electromagnetic coupling between adjacent pairs of wires, which can lead to interference and signal degradation. Here is why twisting cables helps achieve this:

Minimizing Cross Talk:
- By twisting the cables, the electromagnetic fields generated by the signals in each wire are canceled out to some extent. This reduces the chances of interference with neighboring pairs.
- The twisting also helps in maintaining the balance of the transmission line, which further reduces cross talk.

Not for Increasing Bandwidth or Avoiding Physical Damage:
- Twisting of cables does not directly increase the bandwidth for transmission. Bandwidth is determined by various factors like the type of cable, its construction, and signal processing techniques.
- While twisting provides some mechanical protection to the wires, its primary purpose is not to avoid physical damage. Other measures like proper insulation and cable management are more effective in protecting the wires.

In conclusion, the twisting of cables in twisted pair guided media transmission is crucial for minimizing cross talk and ensuring reliable communication. It plays a significant role in maintaining signal integrity and reducing interference between adjacent pairs of wires.
