Optical power adjustment method and device

Abstract

The embodiment of the invention discloses one method and one device for regulating optical power. The method comprises the following steps of: determining a first power attenuation value of a power regulation unit in an optical network, which is related to new service wavelength, according to the path of the new service wavelength and the structure of the optical network; calculating the performance parameter of a channel corresponding to the new service wavelength according to the first power attenuation value; and judging whether the performance parameter of the channel corresponding to the new service wavelength meets the preset tolerance and flatness requirements or not, and regulating the power attenuation value of the power regulation unit related to the new service wavelength to reach the first power attenuation value if a judgment result indicates that the performance parameter meets the preset requirements. The invention also provides another method and another device for regulating the optical power. Through the technical scheme in the embodiment of the invention, network cost can be effectively reduced, and the efficiency and accuracy of regulating the optical power are improved.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for adjusting optical power. Background technique [0002] In the optical network wavelength division multiplexing system, the physical effects of optical fibers and devices on different frequency wavelengths are different. For example, the gain of Erbium Doped Fiber Amplifier (hereinafter referred to as: EDFA) changes with the wavelength, and the optical fiber The attenuation also varies with different wavelengths. Therefore, after the service wavelength is transmitted through the system, the performance of different channels will become unbalanced, resulting in unsatisfactory received signal quality. At the same time, adding new wavelengths or adjusting the power of existing wavelengths in the network will also affect the performance of other wavelengths, thus degrading the quality of received signals of some service wavelengths in the...
