12G SDI Video to Fiber Converter

1-ch 12G-SDI+1-ch Loop+1-ch RS485 to Fiber Converter



The 12G-SDI HD audio and video optical converter is developed by AOA Technology, with independent intellectual property rights, combined with the actual demand of the market. through the single core optical fiber can transmit one channel forward 12G-SDI video and one channel reverse RS485 data / tally signal (optional), realizing no delay, uncompression and high quality signal extension of 20km.

The SDI video converter built-in serial clock recovery, signal equalization and line drive, input automatic detection signal 12G-SDI/6G-SDI/3G-SDI/HD-SDI/SDI/ASI, compatible with SMPTEST2082-1 (12GUHD-SDI), ST2081-1 (6GUHD-SDI), SMPTE424M, SMPTE292M, SMPTE259M, SMPTE297M, SMPTE305M, SMPTE310M standards.

12G SDI to fiber optic converter supports plug-and-play SFP optical module, which can replace the corresponding optical module according to the actual site requirements, the device power consumption is less than 1.5W, the type-C port is used for power supply, supports USB power supply system, which is flexible in use.

The circuit board of 12G HD SDI to fiber converter adopts multi-layer design, stable and reliable, strong anti-interference ability; all components including connector, use products from internationally renowned manufacturers with reliable quality; aluminium shell design, corrosion resistance, excellent thermal and conductive function.


  • Support ST-2082-1 (12G), ST-2081-1 (6G), ST-424 (3G), ST-292 (HD) and ST-259 (SD); compatible with DVB-ASI and AES10 (MADI)
  • Both transmitter and receiver have clock recovery function; (clock restorer can reduce high frequency jitter and completely regenerate data with pure low jitter clock)
  • The clock restorer is locked to 11.88Gbps, 5.94Gbps, 2.97Gbps, 1.485Gbps or 1.001 frequency division sub rate and SMPTE rate of 270Mbps
  • Signal input has automatic cable equalization (EQ) function, output has drive (CD) function
  • Support plug and play SFP optical module, which can replace optical module corresponding to different distances or interfaces according to the actual site requirements
  • Support single mode single fibre / dual fibre transmission distance 20km (default)
  • Support status light display
  • Support USB device power supply
  • Plug and play, no debugging



  • SMPTE compatible with digital serial interface
  • UHDTV / 4K / 8K / HDTV / SDTV video
  • IP media gateway
  • Digital video processing and editing
