Ensure the cable is routed without sharp bends to maintain the integrity of the internal fiber optic strands.

What to consider before purchase

• Verify the required length for your installation to ensure the 30-meter cable is appropriate.
• Confirm that your source and display devices support the HDMI 2.1a standard to utilize the full bandwidth capabilities.
• Check the physical path of the cable to ensure it can be installed without exceeding the minimum bend radius.

Usage recommendations

For optimal performance, always ensure the cable is connected in the correct direction as indicated by the laser-engraved labels. Avoid placing heavy objects on the cable or subjecting it to extreme tension during installation to protect the internal fiber optic components.
