An ethernet cable allows the user to connect their devices such as computers, mobile phones, routers, etc, to a Local Area Network (LAN) that will allow a user to have internet access, and able to communicate with each other through a wired connection. It also carries broadband signals between devices connected through it. In this article, we are going to discuss different types of ethernet cable used in local area networks for reliable internet connection.

Mainly there are three types of ethernet cables used in LANs
Coaxial Cables
Twisted Pair Cables
Fiber optic Cables
A coaxial cable is used to carry high-frequency electrical signals with low losses. It uses 10Base2 and 10Base5 Ethernet variants. It has a copper conductor in the middle that is surrounded by a dielectric insulator generally made of PVC or Teflon. The dielectric insulator is surrounded by a plaited conducting metallic shield which reduces Electromagnetic Interference of the metal and outside interference and finally, the metallic shield is covered by a plastic covering called a sheath usually made of PVC or some other fire-resistant plastic material. Its maximum transmission speed is 10 Mbps. It is usually used in systems, cable TV, etc.
Design: Coaxial cable design choices affect physical size, frequency performance, attenuation, power handling capabilities, flexibility, strength, and cost. It consists of an inner conductor which might be solid or stranded surrounded by an insulator and, to provide flexibility, it is further surrounded by a copper mesh which is further surrounded by a plastic or insulating jacket.
is used in applications where high signal strength is required, this type is most commonly used. They are used in internet lines and lines.
It is used where better signal quality is required; it has a thicker dielectric insulator, they are used in broadband internet, cable TV, etc.
They offer more
bandwidth
and interference rejection; they use an additional copper braid shield. Commonly used in connecting cameras and cable TVs. Etc.
BNC (Bayonet Neil Concelman)
N series Connectors
F Type Connectors
SMA or Subminiature Connector
TNC (Threaded Neil Concelman) etc.
A twisted pair is a copper wire cable in which two insulated copper wires are twisted around each other to reduce interference or crosstalk. It uses 10BASE-T, 100BASE-T, and some other newer ethernet variants. It uses RJ-45 connectors.
Design: A twisted pair cable usually contains two or more conducting wires either shielded by an insulator or not and, further these twisted pairs of wires are coated for protection from any damage.
Types of Twisted Pair Cable
In STP the wires are covered by a copper braid covering or a foil shield, this foil shield adds a layer that protects it against interference leaking into and out of the cable. Hence, they are used for longer distances and higher transmission rates.
Unshielded twisted pair cable is one of the most commonly used cables in
computer networks
at present time. UTP consists of two insulated copper wires twisted around one another, the twisting of wires helps in controlling interference.

Datacenters
Fiber optic cables use optical fibers which are made of glass cores surrounded by several layers of covering material generally made of PVC or Teflon. It transmits data in the form of light signals due to which there are no interference issues in fiber optics. Fiber optics can transmit signals over a very long distance as compared to twisted pairs or coaxial cables. It uses 10BaseF, 100BaseFX, 100BaseBX, 100BaseSX, BaseFx, BaseSX, and BaseBx ethernet variants. Hence, it is capable of carrying information at a great speed.
Design: An optical fiber consists of a core and a cladding chosen for their total internal reflection due to the difference in refractive index between the two. In real optical fibers, the cladding is usually covered with a layer of acrylate or polyimide polymer. The coating protects the fiber from damage and several layers of protective sheathing, depending on the application are added to form the cable.
Types of Fiber Optics Cable
It uses one single ray of light to transmit data. It is used for long-distance transmission.
It uses multiple light rays to transmit data. It is comparatively less expensive.
ST (Straight-Tip) Connector
FC (Fiber Channel) Connector
SC (Subscriber) Connector
LC (Lucent) Connector
Conclusion
Ethernet cables are used to connect devices to a network, allowing them to communicate with each other and access the internet. These cables come in different types, each designed to support various speeds and performance levels. They are essential for both home and office networks, ensuring stable and reliable connections.
