ACT AK4174 DisplayPort cable 40 m Black

The ACT AK4174 DisplayPort cable is a 40 m Active Optical Cable (AOC) designed to carry DisplayPort 2.1 signals over long distances without data loss. The hybrid copper-and-fiber construction supports UHBR10 DP40 bandwidth (40 Gbps) and can handle up to 7680 x 4320 (8K) at 60 Hz with HDR, HDCP 2.2, EDID and multi-channel audio formats. The cable features a Low Smoke Zero Halogen (LSZH) jacket, Kevlar-reinforced fiber and aluminium-foiled shielding, and is supplied in a box. No external power is required; the hybrid design supports 3.3 V along the full length.

Advantages

The cable transmits high-bandwidth 8K video and multi-channel audio over long distances (available up to 100 m) while maintaining signal integrity thanks to its active optical design and UHBR10 40 Gbps capacity. The LSZH jacket reduces hazardous smoke and halogen exposure in case of fire, and the Kevlar protection plus aluminium shielding improve mechanical durability and reduce RFI/EMI for use near sensitive equipment. Connectors are keyed and marked for correct orientation and include a snap-in latch for a secure connection.

Suitable for

• Long-distance video connections in auditoriums, lecture halls and control rooms
• High-resolution displays in medical imaging and diagnostic workstations
• Bridges and navigation systems on vessels that require durable, low-interference cabling
• Data center and monitoring setups where high-resolution, low-noise display links are needed
• Conference rooms and corporate AV installations requiring 8K content distribution

When it may not be suitable

This cable is not necessary for short desktop connections where passive copper DisplayPort cables suffice and where 8K bandwidth is not required. It also may be excessive for simple single-monitor setups that do not need long reach or the LSZH safety properties.

Key specifications

• Cable length: 40 m (available up to 100 m in product family)
• Interface: DisplayPort to DisplayPort, straight male connectors
• DisplayPort version: 2.1
• Maximum resolution and refresh: 7680 x 4320 (8K) at 60 Hz
• Bandwidth: 40 Gbps (UHBR10, 4:4:4)
• Video features supported: HDR, HDCP 2.2, EDID
• Audio support: Multi-channel audio, Dolby TrueHD, DTS-HD Master Audio
• Construction: Hybrid fiber/copper active optical design with Kevlar reinforcement and aluminium foil shielding
• Jacket: Low Smoke Zero Halogen (LSZH)
• Power: Supports 3.3 V over full length, no external power required
• Colour and diameter: Black jacket, approx. 5.2 mm diameter

How to use

Connect one DisplayPort straight male connector to the source device and the other to the display device, ensuring the connectors are oriented according to the markings for source and display. Push until the snap-in latch engages to secure the connection. Use the full 40 m length as required, and avoid tight bends or crushing to protect the fiber core and Kevlar reinforcement. No external power supply is needed; normal DisplayPort source power (3.3 V) is supported across the cable.

What to consider before purchase

• Verify that both source and display support DisplayPort 2.1 features and the desired 8K@60Hz settings
• Confirm the required cable length and whether a longer AOC variant (up to 100 m) is needed
• Check installation environment for routing constraints and LSZH requirements (e.g., public buildings or marine vessels)
• Ensure devices support HDCP 2.2 and the required audio formats if protected content or advanced audio codecs are needed

Usage recommendations

For reliable 8K@60Hz operation, use the ACT AK4174 in installations with stable DisplayPort 2.1 sources and displays, avoid tight bends and mechanical stress on the cable, and follow connector markings to prevent reversed connections. The LSZH jacket makes it suitable for enclosed public and professional spaces where reduced smoke and halogen emissions are required.
