1. An active optical cable, comprising:

  • a first connector, operative to connect to a first apparatus;

    a second connector, operative to connect to a second apparatus; and

    an optical cable, connecting the first connector to the second connector,wherein;

    the first connector has a first electrical-to-optical and optical-to-electrical conversion processing chip, the first electrical-to-optical and optical-to-electrical conversion processing chip has a first non-inverted transmit input-pin and a first inverted transmit input-pin for coupling to a first non-inverted transmit terminal and a first inverted transmit terminal of the first apparatus, respectively; and

    a connection between the active optical cable and the first apparatus is recognized by charging a first capacitor carried by the first non-inverted transmit terminal and charging a second capacitor carried by the first inverted transmit terminal in a common mode impedance measurement.
