The invention discloses a using method of an optical fiber macrobend testing device. The optical fiber macrobend testing device comprises a testing instrument used for controlling an optical fiber toperform macrobend loss testing, a leading fiber used for connecting the output end of the testing instrument and the optical fiber, and a fusion splicer used for fusing the leading fiber and the optical fiber into a whole. The using method comprises the steps that S1, the fusion splicer fuses the leading fiber at the output end of the testing instrument and the optical fiber into a whole; S2, thetest instrument controls the optical fiber to perform looping, and records the attenuation condition and a first power loss value of the optical fiber in a bent state; S3, the test instrument controlsthe looped optical fiber to perform loosening, and records the attenuation condition and a second power loss value of the optical fiber in a linear state; and S4, the test instrument calculates a difference value between the first power loss value and the second power loss value. By using the using method of the optical fiber macrobend testing device provided by the invention, the accuracy of macrobend loss testing can be effectively ensured.
Description
technical field [0001] The invention relates to the field of optical fiber technology, and more specifically, relates to a method for using an optical fiber macrobend testing device. Background technique [0002] In the prior art, most optical fiber and cable factories use V-shaped grooves to connect the lead fiber of the test instrument and the optical fiber under test when performing macrobending tests on optical fibers. However, the pressure block of the V-groove is easy to loosen during the test process, which causes the injection power of the test instrument to change. The power is unstable, so the authenticity of the macrobending loss test cannot be guaranteed. [0003] To sum up, how to provide a test method that can effectively ensure the accuracy of the macrobend loss test is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide a method for using an optic...
