HDMI Cable StarTech.com 50ft 8K Ultra High Speed 48Gbps

The StarTech.com 50ft 8K Ultra High Speed 48Gbps HDMI Cable is a plenum-rated HDMI 2.1 Hybrid Active Optical Cable (AOC) designed to route high-bandwidth video and audio through building plenum spaces. With a 15.2 m length and a slim 4.6 mm diameter, it supports 8K at 60Hz and 4K at 120Hz while combining fiber optic cores and shielded copper conductors to preserve signal integrity over long distances. The cable is unidirectional — follow the SOURCE and DISPLAY labels on the connectors when installing.

Advantages

This hybrid AOC provides high-bandwidth transmission (up to 48Gbps) while offloading low-bandwidth control signals to copper conductors, reducing EMI and maintaining stable 8K 60Hz video. The CMP-rated jacket meets plenum safety requirements with low-smoke, flame-resistant properties. Reinforced fiber with Aramid strands increases tensile strength and the cable is rated for over 6,000 bending cycles at 120°, making it suitable for installations with tight bends. Gold-plated HDMI Type A connectors support reliable contact and optimal signal quality.

Suitable for

• Routing HDMI signals through ceiling plenum and in-wall pathways in commercial or office buildings
• Connecting 8K60Hz or 4K120Hz sources to displays or AV receivers where long cable runs are required
• Installations that require a slim, flexible cable for space-constrained conduits

Key specifications

• Length: 15.2 m (50 ft)
• Bandwidth: Up to 48 Gbps (HBR3)
• HDMI version: 2.1 (supports HDR10+, DSC 1.2a, eARC, HDCP 2.3, FEC)
• Cable type: Hybrid Active Optical Cable (fiber cores + shielded copper)
• Outer diameter: 4.6 mm (0.18 in)
• Connectors: HDMI Type A (Standard) to HDMI Type A (Standard), gold-plated
• Plenum rating: CMP (low-smoke, flame-resistant)
• Durability: >6,000 bending cycles at 120°; Aramid reinforcement
• Directionality: Unidirectional (observe SOURCE and DISPLAY labels)

How to use

Identify the SOURCE and DISPLAY labels on the cable ends and plug the SOURCE-labeled connector into the video source (for example a media player, AV receiver, or graphics output) and the DISPLAY-labeled connector into the display device. Route the slim, flexible cable through plenum-rated pathways such as ceiling plenums or in-wall conduits, avoiding sharp kinks. Ensure both source and display support HDMI 2.1 features you intend to use (for example 8K60 or 4K120) and enable any necessary HDR or audio passthrough settings in device menus.

Usage recommendations

Use the cable only in the indicated direction and follow local building codes for plenum installations. Avoid excessive twisting or tight pinch points when routing; secure the cable without compressing the jacket. For maximum performance, use HDMI 2.1-compatible devices and enable DSC or FEC features on devices when available.
