An optical USB device (106) includes an electro-optical converter (112, 138) configured to receive optical signals from an optical fiber (118) and to convert them into first electrical signals and configured to receive second electrical signals and to convert them into optical signals for transmission to the optical fiber (118). A USB 3.0 pin-compatible connector (122) is coupled to the electro-optical converter (112, 138). The pin-compatible connector (122) is configured for coupling to a USB 3.0 connector (108) of another USB device. The pin-compatible connector (122) includes a first pair of pins (142, 144) configured for transmitting the first electrical signals from the optical USB device (106). The pin-compatible connector (122) also includes a second pair of pins (162, 164) configured for receiving the second electrical signals into the optical USB device (106). The pin-compatible connector (122) also includes a third pair of pins (152, 154) configured for transceiving third electrical signals according to a non-USB serial bus interface protocol to control and configure the electro-optical converter (112, 138).
