    FIGURE 1. The impulse response (blue) of a 4-GHz receiver was measured with a 1-ps, 1530-nm pulse on a 50-GHz oscil­loscope. The step response (red) was then calculated by integrating the impulse response, which can be used to derive the eye diagram.
    The eye diagram of a photo­receiver is a key ingredient in assessing performance of an optical-communications network.
