What is a twisted pair?

Twisted pair cable is a type of cable composed of insulated copper wires. Every two wires are twisted together in opposite directions to form a pair and wrapped in an outer sheath. It is mainly used in Ethernet and telephone networks and includes types such as Unshielded Twisted Pair (UTP) and Shielded Twisted Pair (STP).

What is a twisted pair?

Twisted pair is a type of cable widely used in Ethernet and telephone networks. It consists of insulated copper wires, with every two wires twisted together in opposite directions to form a pair and wrapped with an outer sheath.

Construction of twisted pair:

• Conductor: Twisted pair consists of insulated copper wires, each wire is connected to One contact of the RJ-45 connector.
• Twisted pair: Two wires form a pair and are twisted together in opposite directions. This helps reduce electromagnetic interference (EMI).
• Sheath: The twisted pairs are wrapped in an outer sheath made of PVC or other flame retardant materials.

Types of twisted pairs:

There are different types of twisted pairs, classified according to the number of conductors, twisting steps and sheath type . The most common types are:

• Unshielded Twisted Pair (UTP): The most common type of twisted pair without additional shielding.
• Shielded Twisted Pair (STP): Has a foil or braid sheath to provide additional EMI protection.

Uses of twisted pair:

Twisted pair is mainly used for the following applications:

• Ethernet :Connect computers, servers, and other devices to the network.
• Telephone network: Connect telephone sets and switches.
• Security System: Connect security cameras and other security equipment.
• Industrial automation: Connect industrial equipment and control systems.
