Ethernet cables transmit data between computers in an Ethernet network. They are a type of coaxial cable, consisting eight conductor wires and an RJ-45 connector at either end. The wires are twisted into four pairs and usually color-coded. Ethernet cables have a maximum transfer rate of 10 megabytes per second (Mbps), although operating speeds are also affected by the computer’s Ethernet card.
Types of Ethernet Cables
Kinds of Ethernet Cables include the following:
Straight-through Ethernet cables
Straight-through Ethernet cables connect computers to an Ethernet hub or router.
The wires run parallel throughout the wire. The visible ends arranged identically on both connectors.
Each computer gets an equal bandwidth when connecting to the Internet using straight-through cables.
Crossover Ethernet cables
Crossover Ethernet cables connect computers directly without using a hub or switch.
The wire pairs are crossed from one end to the other. The colored ends are reversed when viewed on the connector.
They are mostly used for file sharing, although internet connection sharing is possible using specialized software.
Choosing Ethernet Cables (Buying tips)
Insulation: Choose an Ethernet cable with a thick insulating coat to protect the wires from damage and interference. Look for a thick, waterproof coating that does not fray or tear easily. PVC coatings usually work for most applications.
Cable length: Choose an Ethernet cable that adequately covers the distance between the router, hub, and terminals. Ten to 30 feet is usually enough for desktops peer-to-peer connections. Laptops and portable devices may need longer wires for mobility.
