Choose an active HDMI cable for long video and audio connections, matching its supported resolution, bandwidth, length, connector type, and directional source-to-display orientation to the system. For fiber optic connections, select a duplex multimode or single-mode active cable based on the network equipment and link requirements, then match the connector style, such as LC or SC, at each end.

Check the cable type, connector format, fiber mode, and system directionality, including whether the installation uses HDMI between a source and display or fiber between compatible network equipment. Match the cable’s rated bandwidth to the required video resolution, refresh rate, HDR, audio, and Ethernet signals, and confirm that the active cable supports the applicable HDMI specification or fiber connection.

Directional active cables must connect the source and display ends correctly, so check the cable labels or arrows before routing and terminating the run. For long cable runs, confirm that the cable length and signal requirements match the system, maintain the recommended bend radius, and avoid excessive pulling, twisting, or strain on the connectors.

Many active HDMI cables draw the power they need from the connected source and display equipment, so they do not require an external USB power supply. Because some active cables are directional, connect the source and display ends as marked and verify the installation requirements for the specific cable.
