Fast. User Friendly. Future-Proof.

Processor speeds, display resolutions and bandwidth capacities are all on the rise – and our hybrid active optical cables can keep pace. Based on Cosemi’s patented hybrid design, our cables employ an innovative architecture that uses fiber optic cables to transmit multi-gigabit data signals and copper wires to carry power and other functions – for the best of both worlds.

Our HDMI OptoHD Active Optical Cables (AOCs) make it possible for the fiber optic connectivity traditionally used in Datacom and Telecom applications to be economically applied to an exponentially growing number of consumer applications.

HDMI combines video and multi-channel audio into a single cable, eliminating the cost, complexity and confusion of multiple cables currently used in A/V systems.

With our easy to use, plug-and-play AOCs, you can take advantage of the latest technology advances including 3D, 4K x 2K resolution and the rich, deep color. And rest assured that you’re well prepared for the next technical advances that come along.

When will the cables be available?
OptoHD Active Optical Cables (AOCs) are currently available through direct sales from Cosemi or by placing a call to a distributor near you.

How should I connect an OptoHD AOC?
OptoHD AOCs are unidirectional. One connector is labeled “Source” and connected to the device providing content. The other connector is labeled “Display” and should be connected to your display (i.e. TV/Monitor).


1 Plenum refers to the air-handling spaces in building construction above the ceiling and beneath the floors. Some building codes require Plenum-rated cable, which has a low-smoke jacket that burns slower in the event of a fire and emits less toxic smoke.

2 Riser rated (indoor household connection) refers to cable which is to be run between floors in non-plenum areas. The fire requirements on riser cable are not as strict.
