Abstract
Provided are a USB driver apparatus using an optical waveguide, a USB external apparatus connected to the same, and a USB system and a USB connection apparatus including the same. The USB driver apparatus includes an optical USB port connected to the USB terminal of the external apparatus and configured to exchange data with the USB terminal using an optical signal; a USB interface part configured to input and output data through the optical USB port; and a photoelectric converter connected between the optical USB port and the USB interface part and configured to convert an optical signal into an electrical signal and vice versa, wherein the optical USB port and the photoelectric converter are connected to each other through the optical waveguide to transmit data as an optical signal. Therefore, it is possible to largely increase a data transmission speed of the USB system.
