The embodiments of the present invention will be further explained with reference to the drawings.

Referring to fig. 1 to 2, an embodiment of the present invention provides an optical fiber protection system, including: the optical fiber protection mechanism 141 comprises a tube body 210 provided with at least one hole and a water-swelling filler 230 arranged in the hole, the optical fiber comprises an optical fiber section provided with an optical fiber code 220, the optical fiber section is fixedly arranged in the tube body 210, and the warning component 160, the demodulator 150 and the light source 120 are respectively connected with the main control module 110.

The light source 120 is a pulsed broadband laser. The pulse broadband laser can provide stable light wave output for the optical fiber coding 220 protection system, and the wavelength band of the light wave can be determined according to the required number of the optical fiber coding 220. In the existing fiber grating processing technology, the fiber grating has a wavelength error, and then the calculation formula of the wavelength band of the light wave can be as follows:wherein F_nWavelength band of light wave, F_rIs the wavelength error, F, of the fiber grating_l3dB bandwidth, n is the number of fiber codes 220. The light source 120 may also be other lasers, and the present implementation is not limited solely.

It should be noted that, in the present embodiment, the first end, the second end and the third end of the circulator 130 are arranged in sequence and the unidirectional passing directions of the three ports are consistent, and since the whole structure involves a plurality of optical components, the loss in the optical fiber should be minimized to ensure the accuracy of the measurement.

In one embodiment, the material of the filler 230 includes a moisture-sensitive material, which may be polyvinyl alcohol, and it should be noted that the moisture-sensitive material may also be other materials, which is not limited in this embodiment.

Referring to fig. 3, the optical fiber protection method based on the optical fiber protection system in the above embodiment includes the following steps:

s310, the main control module controls the light source to output light waves;

s320, the main control module controls the demodulator to detect reflected light of the optical wave reflected by the optical fiber codes of the optical fiber section to obtain the current wavelength value of each fiber grating in the optical fiber codes;

s330, the main control module obtains the average value of the wavelength variation of the optical fiber codes according to each current wavelength value and each initial wavelength value;

s340, the main control module obtains a humidity change wavelength value according to the average wavelength change value of the optical fiber codes in at least three sequentially connected splice boxes;

s350, the main control module obtains a humidity value of the optical fiber protection mechanism according to the humidity change wavelength value;

and S360, when the humidity value is larger than the threshold value, the main control module controls the warning component to warn the water inlet condition of the optical fiber protection mechanism.

The main control module can control the light source to emit light waves to the optical fiber codes in the connector box, control the demodulator to detect reflected light reflected by the optical fiber codes, the current wavelength value and the reflected light intensity of each fiber grating in the fiber code can be obtained, the average value of the wavelength change of the fiber code can be obtained according to the current wavelength value and the initial wavelength value of each fiber grating, then obtaining the humidity change wavelength value according to the average value of the wavelength change of the optical fiber codes in the three sequentially connected splice boxes, obtaining the humidity value of the optical fiber protection mechanism according to the humidity change wavelength value, when the humidity value is larger than the threshold value, the main control module can control the warning component to prompt that the water entering condition of the optical fiber protection mechanism is warned, and can remind a user that the optical fiber protection mechanism needs to drain water, so that the problem of breakage of optical fibers caused by icing of water can be effectively solved.

The calculation formula of the average value of the wavelength variation is as follows:

f_FB1＝[(f₁₁-f₁₀)、(f₂₁-f₂₀)...(f_n1-f_n0)]/n

wherein (f)₁₀、f₂₀...f_n0) For the initial wavelength value of the grating code, (f)₁₁、f₂₁...f_n1) And n is the number of the fiber gratings of the grating code.

In practice, because the temperature variation difference of the optical cable connection head boxes is not large, under normal conditions, the average value of the wavelength variation of the optical fiber codes in the splice boxes is basically the same, and if the average value of the wavelength variation of the optical fiber codes of 3 splice boxes which are sequentially connected has a difference, the difference value can be used as the wavelength value of the humidity variation.

For example: the 3 splice closures are respectively a first splice closure, a second splice closure and a third splice closure, the first splice closure is arranged between the second splice closure and the third splice closure, and the calculation formula of the humidity change wavelength value of the first splice closure can be as follows:

sf_FB1＝f_FB1-(f_FB1+f_FB2+f_FB3)÷3

wherein sf_FB1Is the value of the wavelength of the change in humidity, f_FB1Average value of wavelength variation, f, for encoding optical fibers in a first splice closure_FB2Average value of wavelength variation, f, for encoding the optical fibers in the second splice enclosure_FB3The average value of the wavelength variation encoded for the optical fiber in the third splice enclosure.

The formula for calculating the humidity value of the first closure may be as follows:

H_FB1＝sf_FB1×r

wherein H_FB1The humidity value of the first splice closure, and r is the humidity coefficient.

When the humidity value of the first splice closure is greater than the threshold value, it can be judged that the water entering condition of the optical fiber protection mechanism in the splice closure is serious, and the optical fiber protection mechanism needs to be drained, so that the problem of optical fiber breakage caused by water freezing can be effectively solved.

It should be noted that the humidity coefficient is set according to the optical fiber protection system, and different optical fiber protection systems may be different, and this embodiment is not limited.

It should be noted that the number of splice enclosures used for calculating the difference of the average value of the variation of the coded wavelength of the optical fiber may be set according to the connection condition of a plurality of splice enclosures in the optical fiber protection system, and the embodiment is not limited uniquely.

Referring to fig. 4, before the main control module controls the light source to output the light wave, the method for protecting the optical fiber further includes the following steps:

s410, the main control module controls the light source to output light waves;

and S420, the main control module controls the demodulator to detect reflected light of the optical wave reflected by the optical fiber codes of the optical fiber section, and the initial wavelength value of each fiber grating in the optical fiber codes is obtained.

The initial wavelength value of the fiber grating in the initial state can be obtained and recorded in the main control module for calculating the average value of the wavelength variation of the fiber encoding in the subsequent steps.
