<P> UTP cable is also the most common cable used in computer networking . Modern Ethernet, the most common data networking standard, can use UTP cables . Twisted pair cabling is often used in data networks for short and medium length connections because of its relatively lower costs compared to optical fiber and coaxial cable . </P> <P> UTP is also finding increasing use in video applications, primarily in security cameras . Many cameras include a UTP output with screw terminals; UTP cable bandwidth has improved to match the baseband of television signals . As UTP is a balanced transmission line, a balun is needed to connect to unbalanced equipment, for example any using BNC connectors and designed for coaxial cable . </P> <P> Twisted pair cables often incorporate shielding in an attempt to prevent electromagnetic interference . Shielding provides an electrically conductive barrier to attenuate electromagnetic waves external to the shield; and provides a conduction path by which induced currents can be circulated and returned to the source via ground reference connection . </P> <P> Such shielding can be applied to individual pairs or quads; or to a collection of pairs . Individual pairs are foil shielded, while an overall cable (of multiple pairs) may use any of braided screen or foil or braiding with foil . </P>
