Coaxial cable conducts electrical signal using an inner conductor (usually a solid copper, stranded copper or copper plated steel wire) surrounded by an insulating layer and all enclosed by a shield, typically one to four layers of woven metallic braid and metallic tape.

• Complies with SMPTE standards, supports 3G, 6G and 12G SDI signal transmission, can be used for HD, 3D, 4K and 8K ultra high definition video transmission.
• 75ohm coaxial cable structure, with BNC connectors at both ends, convenient for connecting with various SDI devices.
• Low loss, low attenuation characteristics ensure signal quality is not affected during long-distance transmission.
• Rugged outer design, with certain tensile, torsional and compression resistance, suitable for use in field work environments.
• Cable lengths generally come in 3m, 5m, 10m and other specifications, convenient to choose the appropriate length as needed.
• Commonly used to connect high-definition cameras, switchers, monitors, SDI converters and other SDI video equipment, widely used in television broadcasting, video production, multimedia presentations and other professional fields.

The cable is protected by an outer insulating jacket. Normally, the outside of the shield is kept at ground potential and a signal carrying voltage is applied to the center conductor. The advantage of coaxial design is that with differential mode, equal push-pull currents on the inner conductor, and inside of the outer conductor, the signal's electric and magnetic fields are restricted to the dielectric, with little leakage outside the shield.

Common applications of coaxial cable include video and CATV distribution, RF and microwave transmission, and computer and instrumentation data connections.
