Cosemi's innovative hybrid approach uses copper wires to carry power supply and fiber optic wires to transmit data - US Patent No. 8,948,197

Ultra-Small diameter cable

Diameter is only 3.8 mm, which is much thinner than traditional HDMI copper cable

Length up to 100m

Various lengths 1.5m, 3m, 5m, 10m, 15m, 20m ... up to 100m are available


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.

With the newly released OptoHD™ HDMI, people can now enjoy the true 4K 60fps UHD resolution with 18Gbps bandwidth. In fact, new gaming systems on the horizon - including the PlayStation 4 Pro and Xbox One S - are taking advantage of 4K resolution for the ultimate user experience.


The OptoHD™ of length 10m, 15m & 20m allows you to setup your home theatre without the concern of signal degradation over long distance.
