ABSTRACT:
An interface device includes a transmission level converting circuit for converting a differential amplitude voltage of different signs, output from an IC for a transmission line driving circuit pursuant to IEEE 802.3 10 Base T, into an output voltage of a single pole code. The interface device also includes a reception level conversion circuit for converting a voltage of a single pole code into a differential amplitude voltage of different signs to an IC for driving a transmission line driving circuit, and an optical transceiver to which the single pole code voltage is input and output. A transmission line driving circuit is provided to enable connection to an optical fiber via the optical transceiver.
