Fluke Networks DSXCOAX coaxial cabling has long been used for distribution of data and video signals. The physical construction of coaxial cable, with a center conductor surrounded by one or more shields, makes it highly resistant of electromagnetic interference. This allows coaxial cable to carry high frequency signals over long distances while maintaining a high Signal-to-Noise ratio.

Coaxial cable was one of the first media to support Ethernet with IEEE802.3 standardizing 10BASE2 and 10BASE5, enabling Ethernet transmission up to 185 meters or 50 meters, respectively. Coax is also widely used to distribute broadband video signals in residential and business applications.
