Overview

The Monoprice 143326 is a 24-foot (7.5-meter) active optical HDMI cable built to the HDMI 2.1 Ultra High Speed specification. Where traditional copper HDMI cables struggle to maintain signal quality beyond 10–15 feet at high bandwidths, this AOC cable uses fiber optic strands with active electronics at each connector to deliver a clean, full-bandwidth signal across its entire length. It is 8K certified, supporting resolutions up to 8K at 60Hz and 4K at 120Hz — making it suitable for next-generation gaming consoles, high-end PCs, media players, and 8K displays without compression or signal loss.

The fiber optic construction also makes the cable noticeably lighter and thinner than a copper cable of the same length, which simplifies routing through entertainment centers, conference rooms, or any setup where cable bulk is a concern. Full HDMI 2.1 certification means support for features like eARC, Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM). Compatible with HDTVs, Xbox, PlayStation, Blu-ray players, and PCs, it is a practical solution for anyone who needs to bridge a significant distance between source and display without sacrificing the capabilities of modern HDMI connectivity.

Frequently Asked Questions

What resolution and refresh rate does this cable support?

As a certified HDMI 2.1 cable, it supports up to 8K at 60Hz and 4K at 120Hz, along with the full HDMI 2.1 feature set.

What does AOC (Active Optical Cable) mean for this HDMI cable?

AOC means the cable uses fiber optic technology internally with active electronics at each end, which allows it to transmit high-bandwidth signals over the full 24-foot length without the signal degradation that traditional copper HDMI cables experience at longer distances.

Is this cable directional — does it matter which end I plug into my source?

Yes, active optical HDMI cables are typically directional. The connectors are labeled for source and display, and they must be plugged in accordingly for the signal to pass correctly.

Does this cable support eARC for audio?

Yes, HDMI 2.1 certification includes support for eARC (Enhanced Audio Return Channel), allowing high-quality audio formats to pass from a compatible TV back to a soundbar or AV receiver.

Can I run this cable through walls or conduit?

The fiber optic core is more fragile than traditional copper HDMI cables, so care must be taken with bend radius. Check local building codes before in-wall installation, and avoid sharp bends or crimps.
