ACT AK4172 DisplayPort cable 20 m Black

The ACT AK4172 is a 20 m DisplayPort 2.1 active optical cable (AOC) designed to transmit high-resolution video and multichannel audio over long distances without data loss. The hybrid copper-and-fiber construction and UHBR10 DP40 40 Gbps bandwidth support 8K (7680×4320) at 60 Hz with 4:4:4 color sampling. The cable features a low-smoke zero-halogen (LSZH) jacket, Kevlar-protected fiber and aluminium-foiled shielding, and is supplied in a box.

Advantages

The cable combines copper and optical fiber to maintain signal integrity up to long runs (available up to 100 m) while requiring no additional power and carrying 3.3 V along its full length. Its 40 Gbps UHBR10 bandwidth enables 8K@60Hz 4:4:4 video, HDR, HDCP 2.2, EDID and multichannel audio formats including Dolby TrueHD and DTS-HD Master Audio. The LSZH jacket and low RFI/EMI characteristics make it suitable for environments that require reduced emissions and increased safety.

Suitable for

• High-resolution displays and professional imaging workstations
• Long-distance connections between control rooms and displays in auditoriums or lecture halls
• Medical imaging systems and other sensitive equipment requiring low RFI/EMI
• Maritime navigation and bridge systems where durability and long runs are needed
• Data centre monitoring and corporate meeting rooms with 8K-capable sources and displays

When it may not be suitable

This active optical DisplayPort cable is not intended for simple short desktop connections where a passive copper cable would suffice and be less costly. It may be unnecessary when target displays or source devices do not support DisplayPort 2.1 features, resolutions up to 8K, or the audio/video formats listed.

Key specifications

• Cable length: 20 m (available up to 100 m)
• Connector type: DisplayPort male to DisplayPort male
• DisplayPort version: 2.1 (DP40 UHBR10)
• Bandwidth: 40 Gbps 4:4:4
• Maximum supported resolution: 7680×4320 @ 60 Hz
• Supported features: HDR, HDCP 2.2, EDID, multichannel audio, Dolby TrueHD, DTS-HD Master Audio
• Jacket: Low Smoke Zero Halogen (LSZH)
• Construction: Hybrid copper and optical fiber with Kevlar protection and aluminium foil shielding
• Cable diameter: approx. 5.2 mm
• Colour: Black

How to use

Connect the DisplayPort male connector labelled for the source to the source device and the other end to the display. Ensure connectors are fully seated until the snap-in latch engages to avoid accidental disconnection. No external power supply is required; the cable carries 3.3 V over its full length. Use appropriate routing and strain relief for long runs and secure the cable to prevent sharp bends that could damage the fiber core.

What to consider before purchase

• Confirm both source and display support DisplayPort 2.1 features and the intended 8K@60Hz resolution
• Determine the required cable length; the product is 20 m but longer lengths are available up to 100 m
• Verify installation environment requirements for LSZH jacket and low RFI/EMI
• Assess whether an active optical cable is necessary compared with passive copper solutions for short runs

Usage recommendations

For reliable 8K video and multichannel audio over long distances, use the ACT AK4172 with correctly matched DisplayPort 2.1 source and display devices, avoid tight bends, and secure connectors to maintain a stable, interference-free connection.
