focus on Ethernet cable.
What is Ethernet Cable?
Ethernet cable is the most common network cable type used with wired networks. It connects
network devices such as PCs, routers, and switches within a local area network (LAN). The ethernet
cable resembles a traditional phone cable but is larger and has more wires. The eight insulated
copper wires are split up into four pairs, and the wires are twisted around each other within each
pair to reduce signal interference.

Ethernet Cable Structure
The most common ethernet cable structure is the twisted pair cable. A twisted pair cable is a type
of cable made by putting two separate insulated wires together in a twisted pattern and running
them parallel to each other to improve electromagnetic compatibility.Twisted pair cable reduces
electromagnetic radiation from the pair and crosstalk between neighboring pairs and improves
the rejection of external electromagnetic interference.
Twisted pair cables are of two types: shielded (STP) and unshielded (UTP) . STP cable contains an
extra foil wrapping or copper braid jacket to help shield the cable signals from interference and
transport data faster. STP cables work by attracting interference to the shield, then running it off
into a grounded cable. STP cables are foil-twisted pair (FTP) and shielded/foil twisted pair (SFTP).
UTP cable is low-cost network cable built with a pair of insulated conductors twisted together and
covered with a plastic jacket for protection. It has no foil wrap shielding or braided shielding
screen, which makes the cable smaller in diameter. 24 AWG (short for American Wire Gauge) is the
most commonly seen size of UTP cables.

Ethernet Cable Types
The common types of ethernet cables include Cat5, Cat5e, Cat6, Cat6a, Cat7, and Cat8.
Category 5 (Cat5): is the older type of ethernet cable and made up of four twisted pairs of copper
wire terminated by an RJ45 connector, which has a bandwidth of up to 100 MHz, and supports 10
or 100Mbps speed.
Category 5e (Cat5e): is an enhanced version of the Cat5 cable, which indicates a lower-noise
version where the potential for crosstalk is reduced. The internal interference is lower because the
cable has an average of two twists per centimeter, which allows it to transmit data without
significant signal degradation. Cat5e supports networks up to 1 gigabit (1000 megabits per
second) and comes in shielded varieties, performing better in reducing noise.
Category 6 (Cat6): consists of four pairs of twisted copper wire but features more stringent
specifications for crosstalk and system noise. A Cat6 patch cord has a bandwidth capacity of 250
MHz, which has even stricter specifications when it comes to interference and provides speeds of
up to 10 Gbps.
Category 6a (Cat6a) : The "a" in Cat6a stands for "augmented". Cat6a cable can maintain higher
transmission speeds over longer network cable lengths. With a stronger sheathing, the Cat6a

cable is better suited for industrial environments. However, compared to Cat6 cables, Cat6a cables
are thicker and less flexible.
Category 7 (Cat7): contains four individually shielded pairs inside an overall shield, called
Shielded/Foiled Twisted Pair (S/FTP) or Foiled/ Foiled Twisted Pair (F/FTP). Cat7 cable does well in
reducing signal attenuation and it is relatively stiff when compared to the Cat5e or Cat6a cables.
The newer "Class F" cable is an ideal choice for application environments where transmission of
frequencies up to 600 Mbps is required.
Category 8 (Cat8) : is the latest IEEE standard in copper Ethernet cable. The Cat8 cable can
eliminate crosstalk and enable higher data transmission speeds by wrapping each twisted pair in
foil. Cat8 cable can support 25GB and 40GB Ethernet, which represents a significant leap in data
transfer speed.
Applications
An ethernet cable is used in telephone networks, WiFi routers, TVs, computers, video, security
cameras, data centers, etc.
