2. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Coaxial cable, or coax (pronounced / ˈ k oʊ. æ k s /), is a type of electrical cable consisting of an inner conductor surrounded by a concentric conducting shield, with the two separated by a dielectric (insulating material); many coaxial cables also have a protective outer sheath or jacket.

3. RG-58 - Wikipedia

   en.wikipedia.org/wiki/RG-58

   RG-58/U is a type of coaxial cable often used for low-power signal and RF connections. The cable has a characteristic impedance of either 50 or 52 Ω. "RG" was originally a unit indicator for bulk RF cable in the U.S. military's Joint Electronics Type Designation System. There are several versions covering the differences in core material ...

4. RG-6 - Wikipedia

   en.wikipedia.org/wiki/RG-6

   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 in shielding characteristics, center conductor composition ...

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 ...

6. Wi-Fi over Coax - Wikipedia

   en.wikipedia.org/wiki/Wi-Fi_over_Coax

   Wi-Fi over Coax is a technology for extending and distributing Wi-Fi signals via coaxial cables. As an in-building wireless solution, Wi-Fi over Coax can make use of existing or new cabling with native impedance of 50 Ω shared by a Wi-Fi access point , cabling run, and antenna.

7. Telecommunications cable - Wikipedia

   en.wikipedia.org/wiki/Telecommunications_cable

   Telecommunications cable is a type of guided transmission medium. Telecommunications are based on transmitting and receiving modulated waves/signals through a medium. Types of telecommunications cable include: [1] [2] electrical cables when electric current is carried; transmission lines and waveguides when electromagnetic waves are transmitted; optical fibers when light signals are transmitted.
