A method for a calibration module to calibrate laser bias current in an optical transceiver. The method comprises causing the calibration module to configure a control module of the optical transceiver for a calibration operation, causing the calibration module to determine a laser bias current monitored by the control module, and determining one or more calibration factor values that cause the laser bias current monitored by the control module to substantially match a laser bias current as measured by an external test meter.
