Abstract
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 (1-1), a semiconductor optical amplifier (SOA) (3-1), a splitter (4-1), a data upload and download port (5-1), and a first TEC temperature control module (9-1) to control temperature of the laser (1-1) so as to adjust its output wavelength, and the signal receiver section sequentially includes a filter (7-1), a photo detector (8-1), and a receiving end driving device to change an angle of the filter (7-1) with respect to the optical path so as to make a passing wavelength of the filter adjustable. The first TEC temperature control module (9-1) controls temperature of the laser (1-1), and the receiving end driving device drives the filter (7-1) to change an angle of the filter with respect to the optical path.
