A Device and Method for Controlling Lasing Wavelengths of Tunable Laser Source, and A Wavelength Division Multiplexed-Passive Optical Network Having the Same

摘要

The present invention is an apparatus and method for adjusting the oscillation wavelength of the variable wavelength laser , and wavelength-division having the same discloses a multiplexing passive optical network . Device and method for controlling the oscillation wavelength of the tunable laser according to the present invention , and having the same wavelength division multiplexing passive optical network , the optical power characteristic or obtained by the Rayleigh backscatter or reflection of the reflected light component generated in the optical line. by controlling light using a beating component to match the tunable laser of division multiplexer / demultiplexer and a wavelength demultiplexer automatic transmission wavelength of the oscillation wavelength , wavelength division multiplexing may improve the performance of the passive optical network . ;
