cables for net+ n09

IEEE Standard for Ethernets

802.3 is a set of standards defining the physical layer and media access control (MAC) of wired Ethernet networks, including specifications for cabling and signaling.

Twisted Pair cable

A type of cabling that consists of pairs of wires twisted together to reduce electromagnetic interference. Commonly used in networking for both voice and data transmission. 10Gbps or more at 10 meters

Coaxial Cable

A type of electrical cable that consists of a central conductor, insulating layer, metallic shield, and outer insulation, commonly used for cable television and internet connections.

UTP

A type of twisted pair cable that is widely used in networking due to its affordability and ease of installation. UTP cabling minimizes interference and is commonly used for Ethernet connections.

STP

A type of twisted pair cabling that includes a shield around each pair of wires to further reduce electromagnetic interference, enhancing performance in networking applications.
