Belden 1694A is a 6GHz high performance coax cable solution typically used in professional video applications and designed for minimal signal attenuation over longer distances, ensuring high quality video transmission for HD-SDI and 3G-SDI.
For 4K UHD applications, it’s important to ensure the cable length and specifications support 4K video transmission without degradation. Belden 1694A features a high-grade shield and solid copper conductor that can support 4K UHD 6GHz signals, especially over shorter distances.
However, for longer runs or more demanding setups, specialized 4K UHD video cables such as Belden 4855R and Belden 4694R, with additional shielding or higher bandwidth ratings are recommended.
Belden 1694A patch leads are suitable for DUAL LINK and QUAD LINK 4K UHD applications using 6GHz per link
• SMPTE ST425 3G SDI Single/Dual/Quad Interfaces
• SMPTE ST2081 6G SDI Single/Dual/Quad Interfaces
• SMPTE ST2082 12G SDI Single/Dual/Quad Interfaces
In summary, Belden 1694A can be used for 4K UHD and HD-SDI signals, but always verify distance and signal integrity requirements for your specific setup.
