Abstract

The invention relates to a method for actively discovering a network fault based on optical power reduction of an OTN (Optical Transport Network) wave combining and dividing plate, which comprises the following steps of: calculating a threshold value of an in-use wave channel according to a full configuration wave channel number, an in-use wave channel number and a threshold value of the full configuration wave channel of the OTN wave combining and dividing plate, judging whether an optical power value on the wave combining and dividing plate exceeds the threshold value or not, deducing a potential network fault, and ensuring the stability of the OTN.

Description

technical field [0001] The invention relates to an OTN optical transmission network fault finding technology, in particular to a method for actively discovering network faults based on the optical power drop of an OTN combining and demultiplexing board. The threshold of the fully configured channel is used to calculate the threshold value of the channel in use, to determine whether the value of the optical power on the combiner and demultiplexer board exceeds the threshold, to infer potential network failures, and to ensure the stability of the OTN network. Background technique [0002] With the continuous increase of the transmission rate and transmission channel of the wavelength division system, the input requirements of the wavelength division system on the optical power are getting higher and higher. The abnormal input of the optical power of the wavelength division system will often occur in the daily maintenance work, and in severe cases, it will cause serious damage t...
