50 Ohm

A data transfer cable comes with a difference in resistance, expressed in the impedance of the cable, making some cables a better fit for a specific application. Ranging from cables that are ideal for only transmitting signals (one way) and other cables that are the best pick for the transmission of digital signals.  

The 50Ω cables offer high power handling and low attenuation characteristics making them ideal for devices that functions as a transmitter or transceiver. These cables are also widely used in wireless microphone systems to extend an antenna cable.
