4×3G-SDI Extender

GIGALIGHT’s 4-channel 3G-SDI optical extender is used to extend the range of 4K video transmission through optical fiber between SDI source and receiver equipment, and with 3G-SDI optical module, the transmission distance can be extended by up to 80km. The product is divided into transmitter and receiver: the transmitter receives SDI video signals from the video source, passes through the coaxial cable equalizer, and then converts them into optical signals for transmission through optical fiber; The receiving end converts the optical signal into an SDI video signal, which is then amplified by a coaxial cable driver.


  • Each channel can achieve a rate of up to 3Gbps, and 4 lanes for a total of 12Gbps to support 4K video signal transmission
  • Four 3G-SDI video signals can be extended by up to 80km through single-mode fiber
  • Complies with SMPTE-424M, 292M, 295M, 297M, 305M, 310M and DVB-ASI standards
  • Pluggable SFP ports and BNC interfaces are available for plug-n-play
  • Signals are transmitted through longer, thinner fiber optic cables without electromagnetic emissions (EMI) or radio frequency interference
  • Commercial-grade operating temperatures range from 0 to 60 degrees Celsius
  • Metal housing shields electromagnetic emissions (EMI)RoHS compliant (lead-free)
