Twisted pair Cable – Its Type and uses




Twisted-pair cable  is one of the most common; it’s made up of pairs of wires twisted around each other, as shown in Figure and comes in two varieties:

  1. Unshielded Twisted Pair (UTP)
  2. Shielded Twisted Pair (STP)



Twisted pair cable cable is  used in 10BaseT/100BaseT networks.

Twisted pair cable cable is  categories as follows

  1. Category 1 (CAT1) : For voice-only transmissions. Used in most phone systems today. It contains two twisted pairs.

 

  1. Category 2 (CAT2) :Transmits data at speeds up to 4Mbps. It contains four twisted pairs of wires. It’s also not used in networks and is suitable only for voice grade.

 

  1. Category 3 (CAT3):Transmits data at speeds up to 10Mbps. It contains four twisted pairs of wires with three twists per foot. This is the lowest-level cabling you can safely use in a network.

 

  1. Category 4 (CAT4): Transmits data at speeds up to 16Mbps. It contains four twisted pairs of wires.

 

  1. Category 5 (CAT5):Transmits data at speeds up to 100Mbps. It contains four twisted pairs of copper wire to give the most protection.

 

  1. Category 5e (CAT5e) :Transmits data at speeds up to 1Gbps. It also contains four twisted pairs of copper wire, but they’re physically separated and contain more twists per foot than Category 5 to provide maximum interference protection.

 

  1. Category 6 (CAT6) : Transmits data at speed up to 10Gbps. It contains four twisted pairs of copper wire and is used in 10GBaseT networks
  2. Category 7 (CAT7): It supports frequencies of up to 600 MHz.

 

Each of these six levels has a maximum transmission distance of 100 meters.

 

Advantages of Twisted pair cable :

  1. It is very easy to install and maintain in network.
  2. Twisted pair has very low weight.
  3. This cable can be easily connected

Disdvantages of Twisted pair cable :

Low transmission rates they provide over long distances.
