Abstract

The invention relates to the technical field of optical fiber communication, in particular to an erbium-doped optical fiber amplifier temperature monitoring and early warning method, which comprises the following steps: acquiring the temperature of a pump laser in each erbium-doped optical fiber amplifier during normal operation within a period of time, and optionally selecting two groups of data as a first temperature sequence and a second temperature sequence; calculating a difference value and a similarity between the first temperature sequence and the second temperature sequence, and a mean value of ratios of corresponding elements in the two sequences, obtaining an ambient temperature difference of the two erbium-doped optical fiber amplifiers according to the difference value, the similarity and the mean value, and further obtaining an ambient temperature difference set; classifying the temperature difference set to obtain a classification result, wherein the classification result comprises a plurality of categories; isolated samples in the classification result are obtained and recorded as temperature abnormal samples, and early warning is carried out on the erbium-doped optical fiber amplifier corresponding to the temperature abnormal samples. The temperature of the erbium-doped optical fiber amplifier can be monitored in real time more visually, and the phenomenon of abnormal temperature is prevented.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an erbium-doped optical fiber amplifier temperature monitoring and early warning method. Background technique [0002] At present, in the process of optical fiber transmission, loss and dispersion limit the transmission distance of optical signals. Therefore, during long-distance transmission, it is necessary to add an optical amplifier every certain distance. The optical amplifier amplifies the signal to ensure the quality of optical fiber transmission. The common optical amplifiers generally include Erbium-doped Optical Fiber Amplifier (EDFA for short). The main components of Erbium-doped fiber amplifier are: Erbium-doped fiber (EDF), pump light source, optical coupler, optical isolator, optical filter, etc. When the pump light source used inside generates laser light, it will generate certain noise due to the influence of temperature, and this noise will a...
