Kramer CLS-AOCU/CH-66 Active Optical USB-C to HDMI Cable/66ft/4K@60Hz/18Gbps

Description

The CLS-AOCU/CH active optical USB-C to HDMI cable is designed to deliver uncompressed 4K video and multichannel audio over long distances. It converts a USB-C video output to an HDMI display input using an optical hybrid cable architecture that preserves signal integrity. This cable supports resolutions up to 4K@60Hz and carries HDR and HDCP metadata for modern displays.

Key features include an 18Gbps data path, support for 4:4:4 chroma, and embedded audio up to PCM 8-channel and advanced lossless formats. The cable uses polymer-insulated glass fibers combined with tinned copper conductors to keep the assembly thin and flexible while reducing signal loss. Connectors are 24K gold-plated to ensure corrosion resistance and reliable mating with HDMI ports.

Performance specifications include support for 4K@60Hz (4:4:4), HDR, HDCP 2.2/1.4, and common color spaces such as RGB, YCbCr and BT.2020. The CLS-AOCU/CH maintains up to 18Gbps bandwidth and carries DTS HD and Dolby TrueHD audio formats. The optical hybrid design enables runs up to 30 meters (98ft) without the attenuation typical of long copper cables.

Connectivity is straightforward with a USB-C source termination and an HDMI Type A display termination, both featuring gold-plated contacts. The cable supports transparent EDID management and standard HDMI signaling so it integrates with most modern laptops, media players and professional displays. Reduced susceptibility to EMI and RFI makes the cable suitable for installations where electromagnetic noise is a concern.

Typical applications include boardrooms, lecture halls, digital signage and AV racks where long single-cable HDMI signal runs are required. It is also suitable for connecting USB-C equipped laptops to remote HDMI displays without using bulky extenders or active converter boxes. The thin 4.7mm diameter and flexible construction simplify routing through conduits and furniture grommets.

Installation and build quality emphasize reliability and safety – the jacket is Low Smoke Halogen Free and the cable maintains a 20mm bending radius for repeated handling. Power draw is below 1.5W, minimizing load on host USB-C supplies. Overall, the CLS-AOCU/CH offers a compact optical HDMI solution that balances signal fidelity, flexibility and compliance with industry standards.
