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.
The maximum transmission distance is depending on the bit rate and the quality of the cable. RG-11, RG-6, RG-59, and other cable types can be used. It is also possible to reuse existing coaxial cable when upgrading from an analogue to a digital camera system. The original connector for CoaXPress is a 75 Ω IEC 61169-8 BNC connector.
Many mono 'computer' mics are fitted with TRS plugs. The tip is for the MIC and the ring is for power (to power an electret-condenser style MIC). There are exceptions to the above: Hosa cables use grey and orange for left and right analogue channels. RadioShack cables sometimes use grey and black for left and right.

The phase velocity at which electrical signals travel along a transmission line or other cable depends on the construction of the line. Therefore, the wavelength corresponding to a given frequency varies in different types of lines, thus at a given frequency different conductors of the same physical length can have different electrical lengths.
The various serial digital interface standards all use (one or more) coaxial cables with BNC connectors, with a nominal impedance of 75 ohms. This is the same type of cable used in analog composite video setups, which potentially makes for easier "drop in" equipment upgrades (though may be necessary for long runs at the higher bitrates for older oxidising or lower grade of cable to replaced ...
