HDMI cable EFB Elektronik K5431AOC.50V2 50m

The HDMI Cable EFB Elektronik K5431AOC.50V2 is a 50 m active optical HDMI cable with HDMI Type A connectors on both ends. Using optical fiber instead of copper conductors, this cable transmits high-speed digital video and audio signals with low attenuation and excellent EMI/EMC immunity. It supports up to 4K @ 60 Hz over the full 50 m length and is designed for installations requiring a long, flexible, and slim HDMI connection in black finish.

Advantages

As an active optical cable (AOC), this HDMI cable provides longer reach than traditional copper HDMI cables while remaining flexible and thin. Optical transmission reduces signal loss and interference, ensuring stable 4K @ 60 Hz performance at 50 m without the need for external power. The cable comes with standard HDMI Type A connectors on both ends for plug-and-play compatibility with TVs, projectors and computers.

Suitable for

• Connecting TVs to AV receivers or wall-mounted displays at long distances
• Projector installations in conference rooms, lecture halls or auditoriums
• Studio or control-room setups where EMI immunity and signal integrity are important
• Home theater systems requiring a discreet, slim cable run

How to use

Insert the HDMI Type A connector of the cable into the HDMI output of the source device and the other HDMI Type A connector into the HDMI input of the display device. Ensure connectors are fully seated. No external power supply or signal extenders are required. For best results, avoid sharp bends near the connectors and secure the cable where it crosses traffic paths to prevent strain.

Recommendations

Use gentle bending radii consistent with fiber optic cable handling, avoid kinking, and keep the cable away from strong mechanical stress. If routing through conduits or tight spaces, confirm the conduit diameter accommodates the cable without tight bends.
