Description

A type of communication technology called Ethernet is in charge of connecting various network devices. It is utilized for WAN network channels as well as popular for creating LAN-style channels. Ethernet cables are typically used to link devices to a local network and to the internet. They attach to a range of devices through Ethernet ports. An Ethernet cable is most frequently used to connect a WiFi router or modem to a phone line or internet entry point. Coaxial, twisted pair, and fiber optic cables are the three main types of Ethernet cables used in Local Area Networks (LANs).

Coaxial cables

Low-loss high-frequency electrical impulses are sent using coaxial cables. It makes use of Ethernet versions 10Base2 and 10Base5. Its central copper conductor is encircled by a dielectric insulator, often composed of Teflon or PVC. A braided conducting metallic shield encircling the dielectric insulator minimizes both external interference and metal Electromagnetic Interference (EMI). The metallic shield is then covered with a plastic sheath, typically composed of fire-resistant plastic such as PVC. There is a 10 Mbps maximum transmission speed. It is typically utilized in cable TV, phone systems, etc.

Twisted pair cable

In order to minimize crosstalk or interference, two insulated copper wires are twisted around one another to form a twisted pair of wires. 10BASE-T, 100BASE-T, and a few additional more recent Ethernet variations are supported. Typically, a twisted pair cable consists of two or more conducting wires that are coated to prevent damage and are either protected by an insulator.

Fiber optic cable

Fiber optic cables carry data in the form of light signals, so interference is nonexistent. The optical fibers used in the cables are composed of glass cores encased in multiple layers of cladding material, typically Teflon or PVC. When compared to coaxial or twisted pairs of wires, fiber optics can carry signals over extremely long distances. It makes use of Ethernet versions 10BaseF, 100BaseFX, 100BaseBX, 100BaseSX, 1000BaseFx, 1000BaseSX, and 1000BaseBx. It can therefore transmit information very quickly. Because of their differing refractive indices, the core and cladding of an optical fiber are selected for their total internal reflection. A layer of acrylate or polyimide polymer often covers the cladding in genuine optical fibers. Several layers of protective sheathing are applied to the cable, depending on the application, and the coating guards against damage to the fiber.

Slower-running devices and Ethernet connections can be used with the majority of Ethernet devices. Nonetheless, the weakest components will dictate the speed of the connection. Ethernet is still more used for wired networking even if wireless networks have surpassed it in many places. Compared to wireless networks, wired networks are less prone to interference and more dependable. In a network system, sending data packets from one node to another is the main function of the data connection layer. CSMA/CD (Carrier Sense Multiple Access/ Collision Detection) is an access mechanism used by Ethernet that allows each computer to listen to the connection before sending data over the network.

A chip or card called an Ethernet adapter inserts into a motherboard slot to enable a computer to connect to a Local Area Network (LAN). These were previously exclusively utilized with desktop computers. These days, Ethernet is included into laptop and desktop motherboard chipsets. Switches are used in Ethernet networks to connect multiple devices together and selectively forward Ethernet frames to their destination ports, improving network efficiency compared to older hub-based Ethernet networks. Ethernet is the dominant LAN technology globally due to its cost-effectiveness, scalability, and flexibility. It's used in various environments, including homes, businesses, data centers, and industrial networks.

Ethernet operates at the physical layer and data link layer of the Open Systems Interconnection (OSI) model. It uses various physical media, including twisted-pair copper cable, fiber-optic cable, and wireless transmission. Ethernet has evolved over time to support various speeds, including 10 Mbps (Ethernet), 100 Mbps (Fast Ethernet), 1 Gbps (Gigabit Ethernet), 10 Gbps (10 Gigabit Ethernet), and even faster speeds (40 Gbps, 100 Gbps, etc.) for modern networking needs. Ethernet has been continuously evolving to meet the increasing demands of network bandwidth and is a fundamental technology enabling modern networking infrastructure.
