Multi-Wavelength Label Signal Processing Method, Controller and Storage Medium

A multi-wavelength label signal processing method, performed by a signal sending end of a dense wavelength division multiplexing system, the signal sending end being connected to a signal receiving end, and the method comprising:

• acquiring a service spectrum width of an optical service;
• determining a carrier frequency according to the service spectrum width and a preset carrier frequency range;
• performing modulation processing on wavelength information of the optical service according to the carrier frequency to obtain a single-frequency label signal or a dual-frequency label signal;
• and
• sending the single-frequency label signal or the dual-frequency label signal to the signal receiving end, so that the signal receiving end obtains optical power and the wavelength information according to the single-frequency label signal or the dual-frequency label signal.
