Blog Post: 7 Things You Didn't Know About HDMI Active Optical Cables (AOC)

Published on

An“Active Optical HDMI Cable” or AOC is an HDMI cable that has an active digital equalizer built into the cable. These devices are placed inside the cable connectors.
Regular passive HDMI cables can’t reach much more than 30 feet or severe quality problems will ensue, most likely a loss of signal. This is why we carry only HDMI cables with extra shielding for these lengths.
For longer distances, you need an active optical cable to use HDMI. Let’s go on to the 7 things you did not know about active optical cables:


1) They Allow Thin TV Mounting
Since flat TVs are all the rage, flatter mounts that sit closer to the wall are also becoming more popular. The trouble is, larger-diameter HDMI cables don’t like to bend. The Active Optical Cables with hybrid fiber and copper conductors are thinner and can be bent more easily to get the screens closer to the wall. This is a huge aesthetic update as well as a decrease in cable-bend-induced cable failures. 



2) They Solve the “Intermediate Distance” Problem
When you need a cable between 50 and up to 330 feet for a custom installation, you can use this less expensive active HDMI technology. 
For distances beyond 330 feet we recommend going with HDMI extenders. Of course, when your needs are more extended, you can use the Just Add Power system we wrote about in this blog post.

3) They Make Your Installation Future-Proof
An active HDMI cable is more reasonable to upgrade than solutions involving extenders and converters. That makes it easier to upgrade to that next big technology. 
We strongly encourage anyone installing cable behind walls, in ceilings to go for the very best HDMI cable possible.

4) They Simplify the Installation Process
Since active HDMI cables are 100% self-contained, there’s no need for external power supplies, boxes or adapters to make them work. You just plug them in and go. In the world of home theater and even custom install, simple is always appreciated. 


5) They are Plenum-rated
Our Active Optical Cables are plenum-rated, so you can run them where you need to run them, without worrying about fire codes. 


6) They are Directional
The signal is being actively enhanced, in one specific direction. Both ends are clearly marked. 


7) You Should Only Use One Cable Per Link
You should not use more than one cable per link. They work well when used directly between source and display.
