Calrad 55-668-1 Hdmi Patch Cord 4K Ultra Hd 1 Foot

Product Description

The CALRAD 55-668-1 is a 1-foot HDMI patch cord rated for 4K Ultra HD and 1080p signal transmission with built-in Ethernet channel support. This cable carries high-definition audio and video between HDMI-equipped devices, supporting resolutions up to 4K UHD. The integrated Ethernet channel allows compliant devices to share a network connection over the same cable, reducing cable clutter in rack and wall installations. AV integrators, low-voltage technicians, and experienced installers use this cord for short-run connections in residential and commercial AV systems.

The 55-668-1 is well suited for tight-clearance installations where a full-length cable would create excess slack. Typical applications include connecting Blu-ray players, streaming devices, AV receivers, displays, projectors, and switchers in rack-mounted or shelf-mounted setups. The 1-foot length is commonly used at the equipment rack level to bridge adjacent components or terminate a wall plate to a nearby device.

Key Features

• 4K Ultra HD and 1080p resolution support for high-definition video transmission
• Built-in HDMI Ethernet channel for network data sharing between compatible devices
• 1-foot length designed for short-run and tight-clearance installations
• Carries both high-definition audio and video over a single cable

Compatibility

Designed as a standard HDMI patch cord for use with any HDMI-equipped source, display, or distribution device that accepts a Type-A HDMI connection.

Installation Notes

Installation is performed by low-voltage AV technicians or qualified integrators. Power down connected equipment before swapping cables to avoid signal faults or port damage. Avoid sharp bends at the connector ends, as excessive strain can damage internal conductors. Secure excess cable with hook-and-loop ties to maintain a clean installation.
