Abstract

The present invention relates to the technical field of optical fiber communication, in particular to a method for temperature monitoring and early warning of erbium-doped fiber amplifiers. The group data is recorded as the first temperature sequence and the second temperature sequence; calculate the difference and similarity of the first temperature sequence and the second temperature sequence, and the mean value of the corresponding element ratio in the two sequences, according to the difference, similarity degree and mean value to obtain the ambient temperature difference of two erbium-doped fiber amplifiers, and then obtain the ambient temperature difference set; classify the temperature difference set to obtain the classification result, and the classification result includes multiple categories; obtain the isolated sample in the classification result and record it as For samples with abnormal temperature, an early warning is given to the erbium-doped fiber amplifier corresponding to the sample with abnormal temperature. The invention monitors the temperature of the erbium-doped optical fiber amplifier in real time more intuitively and prevents abnormal temperature phenomenon.

Description

Technical field [0001] The present invention relates to the field of optical fiber communication, and more particularly to a temperature monitoring and early warning method of erbium-doped fiber amplifier. Background technique [0002] At present, during fiber transmission, loss and dispersion limits the transmission distance of the optical signal, so when the long distance transmission is transmitted, the optical amplifier needs to be added every other distance, and the optical amplifier enlarges the signal to ensure the quality of the fiber. Common optical amplifiers typically have erbium-doped fiber amplifiers (Erbium-Doped Optical Fiberamplifier, abbreviated as EDFA). The main composition of erbium-doped fiber amplifiers is: erbium-doped fiber (EDF), pump light source, optocoupler, optical isolator, optical filter, etc. When the pump light source used inside generates a laser, it will cause a certain noise due to the effect of temperature, which affects the quality of the opt...
