Abstract:
1. A method for optimizing an optical transmitter, comprising: varying a plurality of transmitter parameters associated with the optical transmitter in sequential order to obtain their respective optimal levels, wherein the plurality of transmitter parameters include a bias voltage, a crossing level and a peak-to-peak voltage, wherein the respective optimal levels of the plurality of transmitter parameters are obtained based on an acceptable level of a performance metric associated with the optical transmitter; varying a bias voltage associated with the optical transmitter to determine its optimal level; with the bias voltage maintained at its optimal level, varying a crossing level associated with the optical transmitter to determine its optimal level; and with the bias voltage and the crossing level maintained at their respective optimal levels, varying a peak-to-peak voltage associated with the optical transmitter to determine its optimal level; wherein the respective optimal levels of the bias voltage, the crossing level and the peak-to-peak voltage are determined based on an acceptable level of a bit-error rate associated with the optical transmitter; and upon obtaining the respective optimal levels for the plurality of transmitter parameters, checking the optical transmitter to ensure that the optical transmitter is able to function properly within a plurality of system parameters.
