## Long description

The EFB Elektronik HDMI 2.1a cable is a high-performance solution designed for reliable signal transmission over a 20-meter distance. This active fiber optic cable supports high-bandwidth data transfer up to 48 Gbit/s, making it suitable for demanding multimedia applications that require 8K resolution at 60Hz or 4K at 120Hz. The cable features durable HDMI Type A male connectors with gold-plated contacts and a robust stainless steel housing, ensuring a stable connection and resistance to interference.
Advantages
This cable utilizes an active chipset to maintain signal integrity over long distances, preventing data loss that typically occurs with standard copper cables. The inclusion of a flexible, halogen-free TPE jacket provides both durability and ease of installation in tight spaces. With support for advanced audio formats like Dolby Atmos and DTS-HD, as well as HDR10 and 3D video, it delivers a comprehensive audiovisual experience. The laser-engraved markings for Source and Display ensure correct orientation during setup, while the eco-friendly, plastic-free packaging reflects a commitment to sustainable logistics.
Suitable for
Digital signage installations
Professional conference rooms
Broadcast studios
High-end home cinema setups
B2B AV system integration
When it may not be suitable
This cable is an active fiber optic product, which means it is directional and must be connected correctly according to the Source and Display labels. It is not intended for applications where the cable needs to be frequently bent at sharp angles or subjected to extreme physical stress, as this could damage the internal fiber components.

How to use
To install the cable, identify the ends marked Source and Display. Connect the end labeled Source to your media player, computer, or signal generator, and connect the end labeled Display to your monitor, projector, or television. Ensure that the connectors are fully inserted into the ports. Because this is an active cable, it does not require external power, as it draws the necessary energy from the HDMI ports of the connected devices.
What to consider before purchase
Verify the required length for your installation to ensure the 20-meter cable is sufficient.
Confirm that your source and display devices support HDMI 2.1 standards to utilize the full bandwidth.
Check the physical path of the cable to ensure it will not be subjected to sharp bends or heavy crushing forces.
Ensure the directional nature of the cable is compatible with your planned equipment layout.
Usage recommendations: Always handle the cable with care during installation to avoid damaging the internal fiber optic strands. Do not pull the cable with excessive force through conduits or cable trays.
