Choosing an Active Optical HDMI Fiber Cable

An active optical HDMI cable (AOC) carries the HDMI signal over fiber instead of copper, which lets a single cable run far beyond the limit of a passive HDMI cable, up to 100 meters, with no extenders or external power. Key Digital active optical cables combine fiber and copper construction and are plenum rated for installation in air-handling spaces.

The range covers both resolutions and many lengths: 8K 48Gbps plenum cables such as the KD-AOCH33P (33ft) through KD-AOCH164P (164ft), and 4K 18Gbps plenum cables such as the KD-AOCH131P (131ft) through KD-AOCH328P (328ft). Because they are directional and active, they draw the small power they need from the HDMI connection itself.

Choose an active optical fiber cable when you need one clean cable run longer than a passive HDMI cable allows but do not want a CAT6 extender pair, and choose 8K 48Gbps or 4K 18Gbps to match your system. An authorized Key Digital dealer can confirm the length and rating for your run.

Frequently asked questions

What is an active optical HDMI cable?

An active optical HDMI cable (AOC) carries HDMI over fiber, which allows much longer runs than passive copper, up to 100 meters, in a single cable with no separate extender or power supply.

How long can an active optical HDMI cable run?

Key Digital active optical HDMI cables run up to 100 meters (about 328 feet). The 4K 18Gbps range extends farthest, and the 8K 48Gbps range covers the shorter to mid lengths.

What does plenum rated mean?

Plenum rated means the cable meets fire and smoke requirements for installation in air-handling spaces such as above drop ceilings. All Key Digital active optical HDMI fiber cables are plenum rated.

Should I use an optical fiber cable or a CAT6 extender for a long run?

An active optical HDMI cable is a single cable that needs no extender pair or power, which is ideal for a clean point-to-point run. A CAT6 HDBaseT extender is better when you also need switching, USB, or control at the endpoints.

Do these cables support 8K?

Yes. The 8K plenum range (for example the KD-AOCH33P through KD-AOCH164P) supports 8K 48Gbps, and the 4K range supports 4K 18Gbps over longer distances.
