A method and an apparatus for compensating for wavelength drift are disclosed. The method includes: generating, by a burst control circuit, a burst bias current; sending, by the burst control circuit, the burst bias current to a light emitting part and a trigger; converting, by the trigger, the received burst bias current into burst DA data; sending, by the trigger, the burst DA data to a synthesizer circuit; receiving, by the synthesizer circuit, the burst DA data sent by the trigger and the calibrated DA data sent by the MCU respectively; synthesizing, by the synthesizer circuit, the burst DA data and the calibrated DA data to obtain a synthesized signal; and sending, by the synthesizer circuit, the synthesized signal to a temperature control part.

Method and apparatus for compensating for wavelength drift

A BOSA device having an adjustable wavelength in two directions comprises a signal transmitter section and a signal receiver section, wherein the signal transmitter section sequentially includes a laser (-), a semiconductor optical amplifier (SOA) (-), a splitter (-), a data upload and download port (-), and a first TEC temperature control module (-) to control temperature of the laser (-) so as to adjust its output wavelength, and the signal receiver section sequentially includes a filter (-), a photo detector (-), and a receiving end driving device to change an angle of the filter (-) with respect to the optical path so as to make a passing wavelength of the filter adjustable. The first TEC temperature control module (-) controls temperature of the laser (-), and the receiving end driving device drives the filter (-) to change an angle of the filter with respect to the optical path.
