    Effect of optical module eye diagram

    If the signals are too long, too short, poorly synchronized with the system clock, too high, too low, too noisy, or too slow to change, or have too much undershoot or overshoot, this can be observed from the eye diagram. An open eye pattern corresponds to minimal signal distortion.OverviewIn, an eye pattern, also known as an eye diagram, is an display in which a from a receiver is repetitively sampled and applied to the vertical input (y-axis), while the data rat.
