12G-SDI Extender

12G-SDI fiber optic extenders enable the transmission of 12G SDI signals over long distances, which are independent. The maximum transmission distance can reach 80km at 3G-SDI data rate and up to 20km at 12G-SDI data rate. Operating data rates range from 125Mbps to 11.88Gbps. In addition, the MADI, DVB-ASI, SD-SDI, HD-SDI, 3G-SDI, 6G UHD–SDI formats are backwards compatible.


  • SD, HD, 3G, 6G, 12G input data rate automatic detection
  • Transmission distance: 80km (@3G SDI SFP transceiver), 20km (@12G SDI SFP transceiver)
  • Transmits 8K (uncompressed) signals up to 20km
  • Each channel supports resolutions up to 2160p/60Hz
  • Each channel is re-timed individually
    Supported formats:
  1. SMPTE ST 2082-1 (11.88Gbps/s)
