Aug 17, 2022 – The development of ultra-high-definition (UHD) technology is driven by people’s infinite desire for the visual experience. With the prevalence of high-speed network era, video applications such as live streaming, cloud video conferencing, and distance education have emerged, showing the market’s demand for video signals, from ”scene reproduction” to “realistic restoration”.

8K is by far the closest UHD video technology to the real vision of the human eye. Not only by the resolution of 4320x7680, but with a wide color gamut, high color depth, and high dynamic range making a more vivid and realistic color, and more lively motion pictures. It is the top specification in the current UHD TV standard and will be the inevitable trend of future TV development.

FIBERSTAMP always thinks for users and creates for them. To meet the demand for 8K uncompressed SDI baseband video remote transmission, FIBERSTAMP has launched the 48G-SDI (4x12G) broadcast-grade video optical extender kit solution, which is designed to fulfill 20km single-mode fiber transmission of four uncompressed 12G-SDI signals. Each 12G-SDI channel is independent, rate-backward compatible, and supports any SDI operating rate from 270Mbit/s to 12Gbit/s. In addition, the device has built-in the SDI signal equalizer, decoder, clock data recovery circuit, and route driver, which can realize a 4-link 12G-SDI signal input and distribute three 4-link 12G-SDI signals output and backward-compatible resolution. Moreover, it can be applied to professional SDI video signals such as UHDTV/FHDTV/HDTV/SDTV, especially suitable for the transmission of broadcast-grade UHD digital signals.

Each port supports the following rates:

  • SD,HD,3G,6G,12G auto data rate detection
  • SMPTE ST 2082-1 (11.88Gbps/s)
  • SMPTE ST 2081-1 (5.94Gbps/s)
  • SMPTE ST 424 (2.97Gbps/s)
  • SMPTE ST 292 (1.485Gbps/s)
  • SMPTE ST259(360Mb/s),DVB-ASI(270Mb/s),MADI (125Mb/s)
