A method for optimizing an optical transmitter is provided. According to one exemplary method, the optical transmitter is optimized by varying three transmitter parameters including the bias voltage, the crossing level and the peak to peak voltage. Once the respective optimal levels for the bias voltage, the crossing level and the peak to peak voltage are obtained, the optical transmitter is further checked to ensure that the optical transmitter is able to function properly within certain predetermined system parameters.

The eye diagram analyzer constructs both conventional eye diagrams and special eyeline diagrams to perform extinction ratio and mask tests on digital transmitters. It also makes a number of diagnostic measurements to determine if such factors as waveform distortion, intersymbol interference, or noise are limiting the bit error ratio of a transmission system.
