[0031] The core of the present application is to provide an optical fiber installation and modulation assembly to adjust the beam quality of an optical fiber.
[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0033] Optical fiber is a type of fiber made of glass or plastic that serves as a carrier for optical signals and is widely used in various fields. When light travels from a medium with a higher refractive index to a medium with a lower refractive index, total internal reflection occurs if the angle of incidence is greater than the critical angle, allowing the light beam to propagate within the optical fiber. Normally, the beam quality of an optical fiber is fixed once it is manufactured. However, in some fields, different beam quality requirements necessitate the remanufacturing of fibers that meet these requirements, resulting in higher costs.
[0034] Therefore, such as Figure 1 As shown in the illustration, this application discloses an optical fiber mounting modulation assembly, including a mounting wheel 100 and a modulation mechanism 200. One or more adjusting rods 201 compress the optical fiber 500, causing it to deform and thus adjusting the beam quality to meet different beam quality requirements.
[0035] The following will combine Figures 1 to 3 The fiber optic installation modulation assembly disclosed in the embodiments of this application will be explained and described in detail.
[0036] Among them, such as Figure 1 As shown, the mounting wheel 100 may include two opposing wheel plates 101, with a wheel axle 102 for winding optical fibers 500 connected between the two wheel plates 101. When installing optical fibers 500, excess optical fibers 500 can be wound onto the wheel axle 102 for sorting and installation.
[0037] like Figure 1 and Figure 3 As shown, to prevent the optical fiber 500 wound onto the axle 102 from coming off, the optical fiber mounting modulation assembly may also include a fixing assembly 300 for fixing the optical fiber 500. Wherein, as Figure 1 As shown, the fixing component 300 may include a base 301 and a buckle 302. The base 301 can be fixed on the wheel 100. At the same time, by cooperating with the base 301, the buckle 302 can fix the optical fiber 500 between the buckle 302 and the base 301, thereby effectively preventing the optical fiber 500 from coming off the wheel axle 102 and ensuring the stability of the installation of the optical fiber 500.
[0038] In some embodiments, such as Figure 1 and Figure 3As shown, multiple bases 301 may be included, and each base 301 can be fixed to the axle 102 at intervals along the circumferential direction by fasteners such as bolts. Simultaneously, the fastener 302 is adapted to the base 301, meaning each base 301 corresponds to one fastener 302. The fastener 302 has two first mounting holes, and the base 301 may have a second mounting hole adapted to the first mounting holes. This allows the fastener 302 and the base 301 to be connected and fixed by fasteners such as bolts passing through the first and second mounting holes, thereby securing the optical fiber 500 between the fastener 302 and the base 301. It should be noted that the fastener 302 and the base 301 can also be fixed by a snap-fit method, or one end of the fastener 302 and the base 301 can be hinged, allowing the fastener 302 to rotate around it, while the other end of the fastener 302 and the base 301 is connected and fixed by a snap-fit or bolts.
[0039] In some embodiments, such as Figure 3 As shown, the base 301 has a first contact surface 3011 that contacts the optical fiber 500, and the fastener 302 has a second contact surface 3021 that contacts the optical fiber 500. The first contact surface 3011 and the second contact surface 3021 can be used to form a penetration area 303 for the optical fiber 500. The first contact surface 3011 and the second contact surface 3021 effectively prevent damage to the optical fiber 500 when the base 301 and the fastener 302 clamp it, thus protecting the optical fiber 500.
[0040] In some embodiments, such as Figure 1 and Figure 2As shown, to facilitate the fixing of the mounting wheel 100, a mounting base 400 is rotatably mounted on the wheel plate 101 on either side of the mounting wheel 100. The mounting base 400 may have a T-shaped structure and may include a first connecting part 401 rotatably connected to the wheel plate 101 and a second connecting part 402 for fixing to a support surface, such as a wall, marble gantry, or floor. The first connecting part 401 may be located at the middle position of the second connecting part 402 and is vertically arranged. At the same time, at least two fixing holes 4021 are provided on the second connecting part 402, and the two fixing holes 4021 may be symmetrically arranged about the first connecting part 401, so that the mounting wheel 100 can be fixed to the support surface by fasteners such as bolts passing through the fixing holes 4021. Furthermore, by rotating the mounting wheel 100 around the first connecting part 401 of the mounting base 400, excess optical fiber 500 can be easily wound onto the wheel axle 102 for sorting and installation of the optical fiber 500. It should be noted that the mounting base 400 can also adopt an L-shaped structure, a rectangular frame structure, or a triangular frame structure, etc. Of course, the fixing holes 4021 can also be three, four or more, to improve the reliability of the connection between the mounting base 400 and the support surface, thereby improving the stability of the mounting wheel 100.
[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, to facilitate the installation or rotation of the mounting wheel 100, at least two hand-held holes 103 are provided on the mounting wheel 100, and the hand-held holes 103 are spaced apart along the circumferential direction of the mounting wheel 100. The hand-held holes 103 can be two, three, or more, and each hand-held hole 103 can be spaced apart on two wheel plates 101 along the circumferential direction of the mounting wheel 100. The hand-held holes 103 on the two wheel plates 101 are correspondingly arranged so that the operator can pass their hand through the hand-held holes 103 on the two wheel plates 101 to install or rotate the mounting wheel 100. Furthermore, the hand-held holes 103 have an arc-shaped surface that conforms to the operator's hand, allowing the operator to better grip the mounting wheel 100 for installation or rotation.
[0042] like Figure 1 and Figure 2As shown, to make it easier for operators to install or rotate the mounting wheel 100, at least one wheel plate 101 is provided with a plurality of first weight-reducing holes 1011 along the circumferential direction. This means one or more first weight-reducing holes 1011 can be provided on one wheel plate 101, or one or more first weight-reducing holes 1011 can be provided on both wheel plates 101. Similarly, a plurality of second weight-reducing holes 1021 can be provided on the wheel axle 102 along the circumferential direction. This means one or more second weight-reducing holes 1021 can be provided on the wheel axle 102. By providing weight-reducing holes on the wheel plate 101 and wheel axle 102, the weight of the mounting wheel 100 can be effectively reduced, making it easier for operators to install or rotate the mounting wheel 100, while also saving materials and reducing costs.
[0043] In order to achieve adjustment of beam quality, such as Figure 1 and Figure 2 As shown, the modulation mechanism 200 may include at least one or more adjusting rods 201 to squeeze the optical fiber 500, causing the optical fiber 500 to deform, thereby disrupting the regular light reflection inside the optical fiber 500, making the reflection of the light beam propagating in the optical fiber 500 disordered, so as to achieve the mode disturbance effect of the optical fiber 500, and thus achieve the effect of adjusting the beam quality to meet different requirements for beam quality.
[0044] In some embodiments, one or more adjusting rods 201 are movably disposed on a wheel plate 101, such that the adjusting rod 201 abuts against one side of the optical fiber 500, while the other side of the optical fiber 500 abuts against the wheel plate 101. This applies a compressive force to the optical fiber 500 through the adjusting rod 201 and the wheel plate 101, causing the optical fiber 500 to deform and disrupting the regular light reflection within the optical fiber 500, thus achieving a mode-scraping effect and adjusting the beam quality. It should be noted that one, two, three, or more adjusting rods 201 can be movably disposed on a wheel plate 101 to achieve different mode-scraping effects.
[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, multiple adjusting rods 201 can also be movably mounted on the two wheel plates 101. The adjusting rods 201 can be two, three, four, or more, and each adjusting rod 201 can be symmetrically arranged on the two wheel plates 101 to simultaneously compress both sides of the optical fiber 500, causing deformation of the optical fiber 500 and disrupting the regular light reflection within the optical fiber 500, thus achieving a mode-scraping effect. Alternatively, the adjusting rods 201 can be staggered on the two wheel plates 101 to staggerly compress different sides of the optical fiber 500, causing deformation of the optical fiber 500 and disrupting the regular light reflection within the optical fiber 500, thus achieving a mode-scraping effect.
[0046] In some embodiments, such as Figure 1 As shown, in order to adjust the pressure exerted by the adjusting rod 201 on the optical fiber 500, an adjusting hole is provided on the wheel plate 101 to cooperate with the adjusting rod 201. The adjusting rod 201 can be threaded into the adjusting hole to adjust the pressure exerted by the adjusting rod 201 on the optical fiber 500. The adjusting hole can be a threaded hole, and the adjusting rod 201 can have an external thread of a certain length, so that the external thread of the adjusting rod 201 can cooperate with the threaded hole to adjust the pressure exerted by the adjusting rod 201 on the optical fiber 500.
[0047] In some embodiments, the adjustment hole may also be an optical aperture, and a reset elastic element is sleeved at one end of the adjustment rod 201 that passes through the optical aperture. One end of the reset elastic element can abut against the inner wall of the aperture of the adjustment hole, and the other end of the reset elastic element abuts against the optical fiber 500. At the same time, multiple limiting parts can be provided at intervals at the exposed end of the adjustment rod 201, and a limiting slot hole through which the limiting parts pass is provided at the edge of the adjustment hole. When the adjustment rod 201 passes through the adjustment hole and abuts against the optical fiber 500, the reset elastic element is compressed, and the limiting part on the adjustment rod 201 can pass through the limiting slot hole at the edge of the adjustment hole. Then, the adjustment rod 201 is rotated at a certain angle, so that the limiting part on the adjustment rod 201 deviates from the limiting slot hole, thereby making the limiting part on the adjustment rod 201 abut against the inner wall of the aperture of the adjustment hole to fix the adjustment rod 201. It should be noted that there may be two, three, four or more limiting parts, and each limiting part may be arranged at intervals on one side of the adjusting rod 201, or symmetrically arranged on both sides of the adjusting rod 201, or the limiting parts may be arranged alternately on both sides of the adjusting rod 201. This article does not limit them.
[0048] It should be noted that the mode scrambling effect in the above embodiments is only for single-mode fiber 500, but it is not limited to other types of fiber 500 in this article.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
