WAVELENGTH PRESERVATION METHOD OF HIGH DENSITY WAVELENGTH DIVISION LIGHT SOURCE INCLUDING PREDICTION OF WAVELENGTH CHANGE OF LASER DIODE AND WAVELENGTH RESTORATION AND MAINTENANCE FUNCTION

摘要

According to the present invention, disclosed is a method for maintaining a wavelength of a high density wavelength division light source including functions of wavelength change prediction of a laser diode and wavelength restoration and maintenance. According to one aspect of the present invention, the method for maintaining wavelength in a device for maintaining a wavelength of a high density wavelength division light source has an advantage that an optical unit and electronic circuit unit are simpler than a conventional hardware method so as to allow a product to have a small size and be inexpensive.
