EFB Elektronik HDMI-20-00008 HDMI Cable 20 m, HDMI Type A Male to Male, 4K 60Hz, Black

The EFB Elektronik HDMI-20-00008 is a 20-meter active optical HDMI cable engineered for high-quality, long-distance signal transmission. Utilizing advanced fiber optic technology and an integrated signal conversion chip, this cable ensures reliable, uncompressed 4K video at 60Hz without signal loss or interference. It is designed to meet the rigorous demands of professional AV installations, digital signage, and high-end home theater systems.

Advantages

This active optical cable provides superior performance over long distances, maintaining a stable 18 Gbit/s bandwidth that standard copper cables cannot achieve. The inclusion of gold-plated contacts and a durable zinc alloy shell ensures excellent signal conductivity and physical longevity. Furthermore, the cable is encased in a flame-retardant PVC jacket, providing both safety and flexibility. The laser-labeled connectors clearly indicate the Source and Display ends, preventing installation errors, while the eco-friendly, plastic-free packaging reflects a commitment to sustainable logistics.

Suitable for

• Professional AV installations and system integration
• Digital signage and large-scale display setups
• Conference room multimedia systems
• High-end home theater and gaming environments

When it may not be suitable

This cable is an active optical device, meaning it is directional and must be connected correctly according to the Source and Display markings. It is not suitable for applications requiring a passive cable or for environments where the cable must be bent at extremely sharp angles, as this could damage the internal fiber optic strands.

Key specifications

• Length: 20 meters
• Resolution: Up to 4K at 60Hz
• Bandwidth: 18 Gbit/s
• HDMI Standard: 2.0 (backward compatible)
• Connectors: HDMI Type A (Male to Male) with gold-plated contacts
• Audio support: DTS, DTS-HD Master Audio, Dolby Atmos, Dolby Digital, Dolby TrueHD, ARC
• Material: Zinc alloy connector shell, flame-retardant PVC jacket

How to use

To ensure proper operation, identify the ends of the cable marked as Source and Display. Connect the end labeled Source to your output device, such as a media player, computer, or game console. Connect the end labeled Display to your receiving device, such as a monitor, projector, or television. Because this is an active cable, it will draw power from the HDMI port to drive the signal conversion chip, ensuring a stable connection over the 20-meter distance.

What to consider before purchase

• Verify the required length to ensure 20 meters is sufficient for your installation path.
• Confirm that your source and display devices support HDMI 2.0 standards for 4K at 60Hz.
• Ensure the cable path allows for a gentle bend radius to protect the internal fiber optic components.

Usage recommendations: Always handle the cable with care during installation to avoid excessive tension or sharp bending. Ensure that the connectors are fully seated in the ports to maintain a secure connection and optimal signal integrity.
