Media Converter CAVU-S8 Camera Back to 1 RU Box-Full Camera Control Over Fiber

The Nemal CAVU-4K consists of camera fiber optic adapter (TX) and fiber optic base station (RX), designed for long-distance transmission of 4 individual 3G/HD-SDI signals from the camera side to the Base Station, Sony Remote control data, intercom, and tally. The system puts all of the signals needed for multi-camera 3G/HD-SDI production onto 2-SM fibers, terminated in ST connectors.


  • Designed and tested for use outdoors in harsh environments
  • SD, HD, 3G automatic input detection, supports 270Mbit / s - 1.48Gbit / s - 3Gbit / s rate, supports SMPTE-424M 3Gbps HD-SDI, SMPTE-292M HD-SDI, SMPTE-259M SDI serial digital video signals and DVB-ASI signals
  • Uncompressed transmission without delay; Negligible loss
  • More than 10KM transmission distance up to a maximum 80KM
  • Precision aluminum housing, lightweight and convenient, A-type with a flexible pinch
  • Supports Sony Remote control (CCA5)
  • Mic level input (with mute function) and amp functions (volume adjustment)
  • Tally output +12V or dry Contact Closure
  • Wide operating temperature range, low power consumption

Typical Applications:

  • Television studio, mobile studio, remote production
  • EFP Electronic Field Production, major sporting events and large outdoor events
  • ENG camera (outdoor photo camcorders) upgraded to a EFP camera
