1. What is 12G-SDI ?
just as its name implies,12G-SDI is a SDI signal running around 12 Gigabits per second. With the continuous development of ultra-high definition technologies such as 4K and 8K, video clarity continues to improve, bringing users a more real and delicate visual experience. This trend will continue to drive the upgrading of video production, transmission and playback devices. On the basis of 3G-SDI, 6G-SDI and 12G-SDI also emerged. So what is 12G-SDI can bring us and What can we expect from 12G-SDI? What kind of challenges will you meet?  We also want to introduce the development of SDI.

2. How is the development of SDI?
The SDI professional video standard was first developed in 1989 by the Society of Motion Picture and Television Engineers (SMPTE). Since then, six updated SDI standards have been released with one currently in development. These are the SDI standards in the order they were introduced:

SD-SDI---Standard Definition SDI. Published in 1989, SD-SDI is an SMPTE 259M standard that transmits and receives video and embedded audio at bit rates between 177 Mbps and 270 Mbps; it is primarily used for 480i and 576i video formats.
HD-SDI---High Definition SDI. Introduced in 1998, HD-SDI is an SMPTE 292M standard that transmits and receives video and embedded audio at a rate of 1.5 Gbps; it is primarily used for 720p and 1080i video formats.
ED-SDI---Enhanced Definition SDI. Introduced in 2000, ED-SDI is an SMPTE 344M standard that transmits and receives video and embedded audio at a bit rate of 540 Mbps; it is primarily used for 480p and 576p video formats.
Dual Link HD-SDI. Released in 2002, Dual Link HD-SDI is an SMPTE 372M standard that transmits and receives video and embedded audio at a bit rate of dual 1.5 Gbps links, making a combined 3 Gbps; it is primarily used for the 1080p video format.
3G-SDI---3Gbps SDI. Introduced in 2006, 3G-SDI is an SMPTE 424M standard that transmits and receives video and embedded audio at a bit rate of 3 Gbps; it is primarily used for 1080p video format.
6G-SDI---6Gbps SDI. Published in 2015, 6G-SDI is an SMPTE ST 2081 standard that transmits and receives video and embedded audio at a bit rate of 6 Gbps; it is primarily used for 1080p at 60 frames per second and 2160p video formats at 30 FPS.
12G-SDI---12Gbps SDI. Also introduced in 2015, 12G-SDI is an SMPTE ST 2082 standard that transmits and receives video and embedded audio at a bit rate of 12 Gbps; it is primarily used for 2160p video formats at 60 FPS.

3. 12G-SDI advantage and challenge

12G-SDI offers multiple advantages. As a family of video interfaces standardized by SMPTE, SDI and their related interfaces offer nominal data rates when used for transmission of uncompressed, unencrypted digital video signals within television facilities.

12G-SDI offers eight times the bandwidth of normal HD-SDI and offers the simplicity of single cable connectivity. 12G-SDI has the ability to handle high frame rate and deep color 4K/UltraHD signals over a single cable, including up to 100/120fps. This has major benefits for live events, broadcast studios, on set and live venues when it comes to cable complexity, weight, and troubleshooting with far fewer points of potential failure in the signal chain. 12G-SDI over optical fiber further increases the distance that 12G can travel, up to 10km.

Since the HD-SDI era, HZT Technology has been independent research and development, committed to the deep needs of the SDI communication industry, has developed a variety of HD-SDI, 3G-SDI, 6G-SDI and 12G-SDI suitable for the radio and television industry. As well as a variety of customized SDI Video+Audio +Network + Data fiber converter, widely used in a variety of broadcast vehicles, sports events, stage lighting, live broadcast and other fields. HZT Technology has always been adhering to the quality first, and to provide customers with high-quality optical fiber solutions.
