  2. Coaxial cable - Wikipedia

    en.wikipedia.org/wiki/Coaxial_cable

    RG-62 is a 93 Ω coaxial cable originally used in mainframe computer networks in the 1970s and early 1980s (it was the cable used to connect IBM 3270 terminals to IBM 3274/3174 terminal cluster controllers). Later, some manufacturers of LAN equipment, such as Datapoint for ARCNET, adopted RG-62 as their coaxial cable standard. The cable has the ...

  3. RG-6 - Wikipedia

    RG-6 coaxial cable for television signals RG-6 coaxial cable. RG-6/U is a common type of coaxial cable used in a wide variety of residential and commercial applications. An RG-6/U coaxial cable has a characteristic impedance of 75 ohms. The term, RG-6, is generic and is applied to a wide variety of cable designs, which differ from one another ...

  4. 3C-2V - Wikipedia

    en.wikipedia.org/wiki/3C-2V

    A 3C-2V cable. 3C-2V is commonly marked on low cost coaxial cable used for domestic TV signals.. It is one of the options of the Japanese cable standard JIS C 3501. The 3 indicates approx diameter of the conductive core plus the dielectric (diameter of conductive core =0.5 mm, dielectric thickness =1.3 mm)

  5. Coaxial - Wikipedia

    en.wikipedia.org/wiki/Coaxial

    In geometry, coaxial means that several three-dimensional linear or planar forms share a common axis. The two-dimensional analog is concentric. Common examples: A coaxial cable has a wire conductor in the centre (D), a circumferential outer conductor (B), and an insulating medium called the dielectric (C) separating these two conductors. The ...

    en.wikipedia.org/wiki/Copper_conductor

    Copper wires Copper cable Coaxial cable made from copper. Copper has been used in electrical wiring since the invention of the electromagnet and the telegraph in the 1820s. [1] [2] The invention of the telephone in 1876 created further demand for copper wire as an electrical conductor. [3]

  7. RG-59 - Wikipedia

    en.wikipedia.org/wiki/RG-59

    RG-59 coaxial cable is commonly packed with consumer equipment, such as VCRs or digital cable/satellite receivers. Manufacturers tend to include only RG-59 cables because it costs less than RG-6 does. However, given the short lengths provided (usually 4–6 ft or 1.2–1.8 m), this is generally sufficient for its typical use.

  8. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/Ethernet_physical_layer

    RG-58: 50 Ω coaxial cable connects machines together, each machine using a T-connector to connect to its NIC. Requires terminators at each end. For many years during the mid to late 1980, this was the dominant Ethernet standard. Also called Thin Ethernet, Thinnet or Cheapernet. 10 Mbit/s over RG-58 coaxial cabling, bus topology with collision ...

  9. F connector - Wikipedia

    en.wikipedia.org/wiki/F_connector

    The F connector was invented by Eric E. Winston in the early 1950s while working for Jerrold Electronics on their development of cable television. [1] In the 1970s, it became commonplace on VHF, and later UHF, television antenna connections in the United States, as coaxial cables replaced twin-lead. It is now specified in IEC 61169-24:2019.
