Cameras based on the new USB3.1 transmission technology are being widely used in industrial production line inspection,3D scanning, video conference and other fields. But due to the transmission limitation of USB3.1 copper wire, long distance application is limited. In some applications of robot arm, the cable for transmission signals needs not only to be long enough, but also to meet the characteristic of ultra-soft. In order to solve the above two problems, EverPro have launched USB3.1 Gen1 pure optical cable(EPGUP13-A0A4) with AM-AF interface. Adopting BendRobust® special bending-resistance fiber particularly owned by YOFC with ultra-soft wear-resistant insulating materials make the whole cable reach high flexibility standard, flexible and firm. The transmission length can reach to 100 meters which is 20 times that of the traditional copper wire. Built-in particular SuperTT technology can covert USB3.1 Gen1 and USB2.0 protocols to each other allowing USB2.0 devices to share the high-speed bandwidth(5Gbps) of USB3.1 Gen1. It is the only optical cable compatible with USB2.0 at chip solution level.
