Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber testing, in particular to a matching liquid dish device for optical fiber testing. Background Art

[0002] The refractive index of optical fiber is an important parameter in optical fiber transmission. According to different types of optical fibers, they can be divided into single-mode optical fibers, multi-mode optical fibers, microstructured optical fibers, and fluoride optical fibers. Different types of optical fibers have their own characteristics and applications.

[0003] When it is necessary to obtain a three-dimensional refractive index curve of an optical fiber around its periphery, a fiber optic rotating device is usually required to drive the optical fiber to rotate. Each time it rotates an angle, a two-dimensional grayscale image of the optical fiber is obtained through a CCD imaging system, and then the two-dimensional refractive index profile of the optical fiber is calculated. A three-dimensional refractive index curve of the optical fiber around its periphery can be obtained by rotating 360°. When the optical fiber rotates through the rotating device, one end is fixed by the rotating device for rotation, while the other end passing through the matching liquid dish device is prone to tilt and offset, resulting in poor horizontality during optical fiber testing, which in turn affects the optical fiber measurement results.

[0004] Therefore, a matching liquid dish device for optical fiber testing is proposed to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a matching liquid dish device for optical fiber testing, comprising an oil tank body, quartz plates are embedded and installed on both the front and rear sides of the oil tank body, the space between the two quartz plates is used to inject oil, horizontal ceramic ferrules are respectively inserted on both sides of the oil tank body, and a vertical ceramic ferrule is inserted on the top of the oil tank body.

[0007] Furthermore, the quartz plate is installed in the oil tank body through a mounting pressure plate, and a sealing ring is embedded between the mounting pressure plate and the oil tank body.

[0008] Furthermore, a motor fixing bracket is provided on the left side of the oil tank body, a rotating motor is fixed on the motor fixing bracket via a motor fixing member, and a rotating member is fixed on the output shaft of the rotating motor.

[0009] Furthermore, a support platform is formed downward on the top surface of the rotating member, and a main rotating pressure plate is provided on the side of the support platform of the rotating member through rotation of a rotating shaft, and a fixed pressure strip is also fixed on the main rotating pressure plate.

[0010] Furthermore, the bottom of the end of the main rotating pressure plate is adsorbed on the supporting platform by magnetic adsorption.

[0011] Furthermore, the oil tank body includes a U-shaped seat, an oil tank cavity is arranged in the middle of the U-shaped seat, and both sides of the oil tank cavity are mounting holes matching the quartz plate. The quartz plate is locked to the corresponding side mounting holes through the mounting pressure plate, and the horizontal ceramic insert is installed to the U-shaped seat.

[0012] Furthermore, the matching liquid dish device also includes a base, and the motor fixing bracket and the oil tank body are both installed on the base.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The matching liquid dish device for optical fiber testing can constrain the concentricity of the horizontally measured optical fiber by installing the horizontal ceramic ferrule into the main body of the oil tank when testing the horizontal optical fiber, thereby improving the accuracy of optical fiber measurement. When testing the vertical optical fiber, the vertical ceramic ferrule can also be installed into the main body of the oil tank to ensure the verticality of the vertically measured optical fiber when it is vertically inserted.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1In this embodiment, a matching liquid dish device for optical fiber testing includes an oil tank body 8, and quartz plates 12 are embedded and installed on both the front and rear sides of the oil tank body 8. The oil matching the refractive index is injected into the oil tank body 8 between the two quartz plates 12, and because the distance between the two quartz plates 12 is small and slightly larger than the diameter of the optical fiber, the oil will be adsorbed between the two quartz plates 12 through surface tension and will not leak from the end face. During the test, the optical fiber penetrates from the left side of the oil tank body 8 and extends from between the two quartz plates 12 to the right side of the oil tank body 8. Then, by driving the optical fiber to rotate and sampling through the optical lens, the optical fiber profile can be analyzed, and production can be guided and the optical fiber performance can be analyzed.

[0019] The oil tank body 8 includes a U-shaped seat, an oil tank cavity is arranged in the middle of the U-shaped seat, and the two sides of the oil tank cavity are mounting holes matching the quartz plate 12. The quartz plate 12 is locked to the corresponding side mounting holes through the mounting pressure plate 10, and a sealing ring 11 is embedded between the mounting pressure plate 10 and the oil tank body 8. The sealing ring 11 ensures the sealing of the quartz plate 12 after installation.

[0020] As for how to drive the optical fiber to rotate during testing, a motor fixing bracket 3 is also provided on the left side of the oil tank body 8. A rotating motor 1 is fixed to the motor fixing bracket 3 through a motor fixing part 2. A rotating part 4 is fixed to the output shaft of the rotating motor 1. By fixing the end of the optical fiber to the rotating part 4, the output shaft of the rotating motor 1 can be used to drive the rotating part 4 to rotate.

[0021] As for how the end of the optical fiber is fastened to the rotating part 4, the top surface of the rotating part 4 forms a supporting platform downward, and a main rotating pressure plate 5 is provided on the side of the supporting platform of the rotating part 4 through the rotation of the shaft, and a fixed pressure strip 6 is fixed on the main rotating pressure plate 5. The end of the optical fiber is placed on the supporting platform of the rotating part 4, and then the main rotating pressure plate 5 is rotated, and the end of the optical fiber is firmly pressed on the supporting platform of the rotating part 4 through the fixed pressure strip 6, so that the end of the optical fiber can be fastened.

[0022] In addition, in order to improve the stability of the optical fiber fixation, the bottom of the end of the main rotating pressure plate 5 is adsorbed on the supporting platform of the rotating member 4 by magnetic adsorption, so that the end of the optical fiber is less likely to fall off when it is rotated after being pressed.

[0023] In order to ensure that the optical fiber is not easily displaced during rotation, horizontal ceramic ferrules 7 are respectively inserted on both sides of the oil tank body 8, and the horizontal ceramic ferrules 7 are installed in the U-shaped seat of the oil tank body 8 by fastening bolts. The horizontal ceramic ferrules 7 can be used to constrain the concentricity of the horizontal measurement optical fiber, thereby improving the accuracy of optical fiber measurement.

[0024] The matching liquid dish device also includes a base, and the motor fixing bracket 3 and the oil tank body 8 are both installed on the base. At the same time, the matching liquid dish device can be used for dual purposes and can also measure the vertical optical fiber, and a vertical ceramic ferrule 9 is inserted at the top of the oil tank body 8, and the vertical measurement optical fiber can be inserted between two quartz plates 12 through the vertical ceramic ferrule 9, thereby ensuring the verticality of the vertical measurement optical fiber when it is vertically inserted.

[0025] By using the matching liquid dish device for the above optical fiber test, it can be ensured that the optical fiber is not easily offset when rotating, thereby improving the accuracy of optical fiber measurement. The specific measurement method is as follows:

[0026] When testing the horizontal optical fiber, the oil matching the refractive index is injected into the space between the two quartz plates 12 in the oil tank body 8, and one end of the test optical fiber is placed on the support platform of the rotating member 4. Then, by rotating the main rotating pressure plate 5, the end of the optical fiber is pressed onto the support platform of the rotating member 4 by the fixed pressure strip 6, so that one end of the optical fiber can be fastened, and the other end of the optical fiber passes through the horizontal ceramic ferrule 7 on one side, and extends to the oil between the two quartz plates 12 in the oil tank body 8, and then passes through the horizontal ceramic ferrule 7 on the other side. Finally, the rotating member 4 is driven to rotate by the output shaft of the rotating motor 1, and the test optical fiber is driven to rotate, so that sampling can be performed through the optical lens, the optical fiber profile can be analyzed, and production can be guided to analyze the optical fiber performance.
