Twisted pair Ethernet is an Ethernet computer network that uses twisted pairs of insulated copper wires for the physical layer of the network, which is combined with the data link layer.
Twisted pair cable wires are twisted around each other to decrease obstruction from other twisted pairs in the cable. The two twisted wires assist in decreasing crosstalk that can disrupt signals and reduce electromagnetic induction, which produces voltage across a conductor transferring through a magnetic field.
Typically, twisted pair has less bandwidth than other Ethernet standards such as optical fiber and coaxial cable.
Twisted pair Ethernet may also be known as Ethernet over twisted pair.
Ethernet is a standard for connecting computers to a local area network (LAN). Twisted pair is the most economical LAN cable and is often used by older telephone networks, although many networks have twisted pair wiring somewhere within the network.
Presently, two of the most common types of twisted pair Ethernet are:
Both the 100BASE-TX and 1000BASE-T use a standard 8P8C connector that has a male plug and female jack, each of which has eight evenly spaced conducting channels. Compared to 10BASE-T, the 100BASE-TX and 1000BASE-T are a lot more efficient.
The majority of twisted pair Ethernet standards can be wired directly by lining up the pins. Other twisted pair Ethernets are connected by using the crossover method, which joins the receiver to the transmitter and the transmitter to the receiver. Both the 100BASE-TX and 1000BASE-T are designed to use at least a Category 5 cable with a maximum cable length of 100 meters. Newer connections use a Category 5e.
