Common USB 3.0 cables can only extend to 3 meters, so the popularization speed of USB 3.0 is limited. In order to solve the above problem, EverProhas developed active optical cable USB 3.0 solution based on optical fiber transmission. Meanwhile, in order to realize signal extension, a hub product (EPU3H01AR) based on Super TT technology has also been specifically developed. Used with USB3.0 pure active optical cable, the transmission distance can reach 100 meters.And it can be backward compatible with USB 2.0 devices.
