Title:
METHOD FOR DETERMINING OPTICAL SIGNAL POWER CHANGE AND POWER CALCULATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/081931
Kind Code:
A1
Abstract:
The embodiments of the present application provide a method for determining an optical signal power change and a power calculation device. The method of the embodiments of the present application comprise the following steps: obtaining a first optical signal comprising a plurality of wavelength signals, the plurality of wavelength signals being distributed on a plurality of wave bands, different wave bands corresponding to different wavelength signals, each band comprising the wavelength value of at least one wavelength signal; then, measuring the optical power of each wave band and the center wavelength signal of each wave band and obtaining a preset single-wave transmission power and preset coefficient; then, determining the equivalent number N of equivalent wavelength signals according to the optical power of each wave band and the preset single-wave transmission power, and determining, according to the optical power of each wave band and the center wavelength signal of each wave band, the equivalent wavelength signal corresponding to the first optical signal; further, determining, according to the preset coefficient, the equivalent wavelength signal, the equivalent number, and the preset single-wave transmission power, the target power used for compensating a first power change value of the first optical signal transmitted in the optical fiber.
