Twisted pair ethernet

What is Twisted Pair Ethernet?
Twisted Pair Ethernet is an Ethernet computer network that uses twisted pairs of insulated copper wires for the physical layer of the network that is combined with the data link layer.

Twisted pair cables are twisted around each other to avoid obstacles from other twisted cable pairs. The two twisted wires help reduce crosstalk, signal interruption, and electromagnetic induction can reduce the voltage generated across a conductor that flows through a magnetic field.
Typically, twisted pair has less bandwidth than other Ethernet standards, such as B. optical fibers and coaxial cables. Twisted pair Ethernet can 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 lines somewhere on the network.

Currently, two of the most common types of twisted pair Ethernet are:

- Fast Ethernet or 100BASE-TX with a transmission speed of 100 Mbps
- Gigabit Ethernet (1000BASE-T) with 1 Gbit / s

Both the 100BASE-TX and 1000BASE-T use a standard 8P8C connector with a male plug and female socket, each with eight equally spaced channels. Compared to 10BASE-T, the 100BASE-TX and 1000BASE-T are much more efficient.

Most twisted pair Ethernet standards can be wired directly by stringing the pins together. Other twisted pair Ethernets are connected using the crossover method, which connects the receiver to the transmitter and the transmitter to the receiver. Both the 100BASE-TX and the 1000BASE-T are designed so that at least one Category 5 cable with a maximum cable length of 100 meters is used. Newer connections use a category 5e.
