What Is the Kordz R.4?
The Kordz R.4 is a 48Gbps passive HDMI cable engineered for mission-critical rack and marine installations. It succeeds the R.3 18Gbps HDMI Cable and supports the full 48Gbps data rate, enabling uncompressed 8K video and the complete HDMI 2.1 feature set, including eARC, VRR and QMS. The cable also brings advances in shielding, mechanical stability, construction and safety compliance.
How Does the R.4 Maintain Signal Integrity?
The R.4 maintains signal integrity through a layered shielding design built to reject electromagnetic interference. A full-metal internal connector housing works with a 95% coverage copper braid over a 125% coverage foil shield to hold signals steady in electrically noisy environments, a common challenge in dense rack setups and equipment-heavy spaces.
What Makes the R.4 Different for Rack Installations?
For rack installations, the R.4 combines a compact die-cast connector assembly with a slimmer cable diameter and precise one-foot length increments from one foot to nine feet, 10 inches. That mix supports clean cable management, improved airflow and efficient routing in high-density equipment racks, letting integrators keep systems organized and running cool.
How Does the R.4 Handle Marine Environments?
The R.4 handles marine environments with a secure 2-kilogram retention HDMI connector designed to withstand constant vibration and movement. It also features a full LSZH cable construction that meets IEC60332, IEC60754 and IEC61034 requirements for low-smoke, zero-halogen performance, an important consideration for safety-conscious installations.
Why Should Integrators Take Note?
Integrators should take note because the R.4 targets the practical demands of critical HDMI infrastructure rather than spec-sheet numbers alone. “The R.4 is purpose-built for integrators who require absolute confidence in critical HDMI infrastructure,” says Kordz Managing Director James Chen. “It reflects a focused engineering approach to real installation challenges, such as mechanical stability, EMI control, airflow, and compliance, while ensuring systems remain future-ready.”
Where Can Integrators See the R.4?
Integrators can see the R.4 at CEDIA Expo 2026, Booth 3032, where Kordz will display it alongside the PRO4 Active Optical HDMI Cable. Both products are available now, and product details plus the nearest distributor can be found at kordz.com.
What Is the “Cables That Hold Their Own” Demo?
The “Cables that hold their own” demo is a live booth demonstration of Kordz cable strength and durability. Kordz shows the 20-kilogram pull strength of its PRO4 Active Optical HDMI Cable by using it to suspend a full box of Cat6 cable while simultaneously powering a live TV, giving attendees a hands-on look at how the cable performs under load.
