ABSTRACT:
A method for a laser system to compensate a variability of a signal converter in the laser system includes generating a temperature signal corresponding to a temperature of a laser and adjusting a signal of the signal converter based on at least the temperature signal. A laser transceiver includes a memory, a controller, a bandwidth circuit, and a modulation driver. The controller generates at least one control signal set by a host in the memory. The bandwidth circuit is a programmable low-pass filter (LPF) receiving the control signal and at least one input terminal receiving at least one data signal. The programmable LPF filters the data signal based on the control signal. The modulation driver has at least one input terminal receiving the filtered data signal. The modulation driver provides a modulation current to a laser in response to the filtered data signal.
