Hybrid Cable

HiroSys OB1 cable is designed for outside broadcasting applications where it is necessary to combine in single cable different signals: audio, video and power. This allows having only one cable running from the field where camera, monitor and mixer are located to the OB vehicle. The power conductors have a double spiral tinned copped shield and overall tinned copper braid shield and PVC jacket complete the cable.



  • Digital 3G-SDI transmission including digital audio and power supply.
  • Transmission distance under SMPTE 424M is up to 100m for 3Gb/s signal.
  • Excellent shielding and super low damping values.
  • Ideal for broadcasting vehicle applications, sporting events and big live preformance.
