Which type of cabling is typically used for Ethernet networks?

Twisted pair cabling is the standard choice for Ethernet networks due to its balance of performance, cost, and simplicity in installation. This type of cabling consists of pairs of insulated copper wires twisted together, which helps to reduce electromagnetic interference and crosstalk between the pairs.

Twisted pair cables come in variations such as unshielded twisted pair (UTP) and shielded twisted pair (STP), with UTP being the most common for Ethernet connections in both residential and commercial settings. The Cat5e, Cat6, and Cat6a standards associated with twisted pair cables support different speeds and bandwidths, making them suitable for a range of networking needs, from basic home networks to data centers requiring high-speed connections.

Other cabling options like coaxial and fiber optic are used in specific applications but are not the typical choice for standard Ethernet networks. Coaxial cabling, while historically used for earlier Ethernet standards, has largely been supplanted by twisted pair due to its bulkiness and limitations in terms of speed and distance. Fiber optic cabling, while offering high speed and long-distance capabilities, is more expensive and generally used for backbone connections or in environments where high data transmission speeds and security are critical.
