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.
