Quote:Cosemi has introduced the industry’s first USB 3.1 Gen 2 hybrid active optical cables (hAOC), which enable USB connectivity over distances upwards of 50 meters. The cables will be available with various connectors and therefore will be able to address various applications.

As you might guess from the name, Cosemi’s USB 3.1 Gen 2 hybrid active optical cables use fiber optics for data transfers, which is further paired with copper wires for control and power. The data portion of the cable is fully USB SuperSpeed+ capable, meaning it can transfer 10Gbps in each direction. Notable, since hAOCs can power themselves, unlike other solutions they do not need any extension boxes or repeaters, making them simpler and more reliable. Using fiber for the data channel also means that the cables are more resistant against EM and RF interference, which is particularly important for medical applications.
