It should be noted that the test instrument 1 may send a signal to the optical fiber 4, receive a signal transmitted by the optical fiber 4, and analyze and process the signal transmitted by the optical fiber 4 during the macrobending loss test, so as to obtain the macrobending loss value of the optical fiber 4. In order to ensure the accuracy of signal transmission between the testing instrument 1 and the optical fiber 4, the connection between the output end of the testing instrument 1 and the optical fiber 4 must be ensured to be tight, so that the optical fiber 3 and the optical fiber 4 are fused into an integrated structure through the fusion splicer 2, the optical fiber 4 can be effectively ensured not to be loosened from the optical fiber 3 during macro-bending testing, and then the macro-bending loss testing result of the optical fiber 4 can be ensured to be accurate and real.
The structure, the size, the position and the like of the test instrument 1, the leading fiber 3 and the fusion splicer 2 can be determined according to actual conditions and actual requirements in the actual application process.
When the optical fiber macrobending test device provided by the invention is used for carrying out macrobending loss test on the optical fiber 4, the fusion splicer 2 can fuse the leading fiber 3 and the optical fiber 4 into a whole to realize the coupling of the mode field of the optical fiber 4, so that the connecting effect of the leading fiber 3 and the optical fiber 4 can be effectively ensured, and the influence on the subsequent optical fiber 4 macrobending loss test is avoided. After the fusion splicer 2 fuses the optical fiber 3 and the optical fiber 4 into a whole, the testing instrument 1 can control the optical fiber 4 to perform macrobending loss testing operation, so that the testing instrument 1 can obtain an accurate macrobending loss testing result.
Therefore, when the optical fiber macrobending test device is operated by using the use method provided by the invention, firstly, the optical fiber 3 and the optical fiber 4 can be fused into a whole by using the fusion splicer 2, and then the optical fiber 4 is subjected to macrobending loss test operation by using the test instrument 1.
Preferably, S1 further includes: the end face of the lead fiber 3 and the end face of the optical fiber 4 are respectively manufactured, and the end face of the lead fiber 3 and the end face of the optical fiber 4 are fused by the fusion splicer 2.
It should be noted that the optical fiber macrobend testing device may further include a cutting knife for making the end faces of the optical fiber lead 3 and the optical fiber 4. Namely: at first can cut respectively through the cutting knife and draw fine 3 and optic fibre 4, so that draw fine 3 and optic fibre 4 and all produce the higher terminal surface of roughness, then, reuse heat sealing machine 2 will draw 3 terminal surfaces of fine and 4 terminal surfaces of optic fibre to weld, this butt fusion in-process, heat sealing machine 2 can utilize high-voltage arc will draw 3 terminal surfaces of fine and 4 terminal surfaces of optic fibre to melt, and simultaneously, can utilize high accuracy motion mechanism to impel gently and draw 3 terminal surfaces of fine and 4 terminal surfaces of optic fibre, so that draw under the molten condition fine 3 and optic fibre 4 and fuse into the integral type structure, finally can realize the coupling in 4 mode fields of optic fibre, so as to ensure that the injection power of testing instrument 1 is stable, finally can effectively guarantee the authenticity of macrobend loss test.
Preferably, S1 further includes: if the fusion loss of the end face of the leading fiber 3 and the end face of the optical fiber 4 exceeds a limit value, the end face of the leading fiber 3 and the end face of the optical fiber 4 are manufactured again, and then fusion operation is carried out; if the fusion loss of the end face of the lead fiber 3 and the end face of the optical fiber 4 does not exceed the limit value, operation S2 is performed.

In this embodiment, can set up a loss default that is used for judging the fusion effect of leading fibre 3 and optic fibre 4 in advance according to actual conditions and actual demand, if the detector detects that the fusion loss that leads between fibre 3 and the optic fibre 4 surpasss the loss default, then the feedback ware can send a signal to the suggestion user leads the fusion effect of fibre 3 and optic fibre 4 relatively poor, needs to weld the operation again. If the detector detects that the fusion loss between the leading fiber 3 and the optical fiber 4 does not exceed the loss preset value, the feedback device does not send a signal, the fusion effect of the leading fiber 3 and the optical fiber 4 meets the requirement, and a user can utilize the testing instrument 1 to carry out macrobend loss testing operation on the optical fiber 4.
The shape, size, structure, etc. of the detector and the feedback device can be determined according to actual conditions and actual requirements in the actual application process.
It should be noted that, when the optical fiber macrobending test device is operated by using the method provided by the present invention, firstly, the optical fiber 3 and the optical fiber 4 can be cut by using the cutting knife to manufacture a smooth and flat end surface. Then, the fusion splicer 2 performs fusion splicing operation on the end face of the lead fiber 3 and the end face of the optical fiber 4. The fusion splicer 2 can melt the end faces of the leading fiber 3 and the optical fiber 4 by using a high-voltage electric arc, and can smoothly push the leading fiber 3 and the optical fiber 4 by using a high-precision motion mechanism, so that the leading fiber 3 and the optical fiber 4 are fused into a whole, and the coupling of the mode field of the optical fiber 4 is realized. The fusion splicer 2 can also detect the flatness and smoothness of the input end face and the output end face of the optical fiber 4. When the flatness and the smoothness of the optical fiber 4 do not meet the requirements, the fusion splicer 2 sends an alarm to stop the current fusion splicing operation, so that the stability of the injection power of the testing instrument 1 can be ensured by utilizing the fusion splicer 2 to fuse the lead fiber 3 and the optical fiber 4, and the true accuracy of the macrobend loss test of the optical fiber 4 is ensured.
It should be further noted that the limit value and the loss preset value may be the same value, and the value may be selected and determined according to actual conditions and actual requirements in the actual application process.
Furthermore, when the fusion splicing operation is performed, if the fusion loss of the end face of the lead fiber 3 and the end face of the optical fiber 4 exceeds a limit value, the end faces of the lead fiber 3 and the optical fiber 4 need to be newly manufactured, and then the fusion splicing operation is performed on the lead fiber 3 and the optical fiber 4 by using the fusion splicer 2.
If the fusion loss of the end face of the optical fiber leading 3 and the end face of the optical fiber 4 does not exceed the limit value, the testing instrument 1 can control the optical fiber 4 to perform macrobend loss testing, that is, the optical fiber 4 can be controlled to perform looping operation, the attenuation condition and the first power loss value of the optical fiber 4 in a bending state are recorded, then the looped optical fiber 4 is controlled to perform loosening operation, the attenuation condition and the second power loss value of the optical fiber 4 in a linear state are recorded, and finally the testing instrument 1 can obtain the macrobend loss value of the tested optical fiber 4 by calculating the difference value of the first power loss value and the second power loss value.
In addition, it should be added that when the fusion splicing effect between the leading fiber 3 and the optical fiber 4 is judged, whether the fusion splicing effect is smooth or not can be judged by observing whether the fusion splicing part of the leading fiber 3 end face and the optical fiber 4 end face on the fusion splicer 2 is smooth or not, if the fusion splicing part is smooth and has no burrs or the like, the fusion splicing effect of the leading fiber 3 end face and the optical fiber 4 end face can be better indicated, and if the fusion splicing part is not smooth and has burrs or the like, the fusion splicing effect of the leading fiber 3 end face and the optical fiber 4 end face can be poorer indicated, so that a user needs to rework the end faces of the leading fiber 3 and the optical fiber 4 and perform fusion splicing operation.
