Answer:
Co-axial Cable
Explanation:
Twisted-pair cabling and fiber-optic cabling have essentially taken the place of coaxial cable in local area network (LAN) deployments inside of buildings and high-speed network backbones, respectively.
A solid copper core used for signal transmission is typically found in coaxial cabling, which is then wrapped in a series of layers including inner insulation, Aluminium foil, a copper braided mesh, and outer protective insulation. While a solid conductor is less flexible and more challenging to install than a stranded one, it offers better conductivity. Aluminum foil and copper mesh act as a cover for the inner copper core, which is typically protected with PVC (polyvinyl chloride) or a non-stick coating. The mesh serves as the cable's point of grounding so that the circuit can be completed.
Co-axial cable is available in a range of types and grades. The most prevalent are
1. Thick net cabling, an older type of cabling used for retrofit installations of 10Base5 Ethernet backbones. RG-8 or N-series cabling is the name for this typically yellow cable. Only cables identified as IEEE 802.3 cables, strictly speaking, qualify as real thick net cables.
2. Small Ethernet deployments in 10Base2 networks employ thin net coaxial cabling. RG-58A/U cabling, which features a stranded conductor and a 53-ohm impedance, is the standard name for this type of coaxial cable. To connect to other networking components, this type of cable employs BNC connectors, and terminators are required at the free ends to stop signal bounce. ARCNET cabling, which uses thin coaxial cabling called RG-62 cabling with an impedance of 93 ohms.
3. RG-59 cabling, which is used for cable television (CATV) connections.
