However, currently the optical fibers are fixed to the cable management rack in bundles. When the number of optical fibers in each bundle in the unit is large, it is not easy to distinguish which port on the patch panel the optical fiber corresponds to, and it takes time to find it.

[0029] In order to better understand the technical content of the present invention, specific embodiments are described below in conjunction with the accompanying drawings.

[0030] At present, the optical fibers on the optical fiber distribution frame are evenly distributed and are all on the plug-in panels inclined vertically or at a fixed angle. When the optical fibers are arranged to both sides, due to the different distances from the wire bundle bundling points, the bending degrees at the connection between the optical fibers and the plugs are also inconsistent. It is usually manifested as a large bending degree close to the bundling point and a small bending degree away from the bundling point. Therefore, the outermost optical fibers may cause large signal transmission losses due to the large bending degree. The first aspect of the utility model proposes an optical fiber distribution frame, which aims to reduce the bending degree of the outer optical fibers, including a distribution frame 10 and an optical fiber wiring module 20.

[0031] like Figure 1 As shown, the patch panel 10 is arranged and installed on the cabinet, and the optical fiber wiring module 20 is arranged on the front side of the patch panel 10 and is used to insert the optical fiber. The patch panel 10 adopts a unit structure, and the patch panel 10 can be provided with a single row, a double row or a plurality of rows of optical fiber wiring modules 20. Figure 1 For example, double rows of optical fiber connection modules 20 are arranged in upper and lower distributions.

[0032] Furthermore, the optical fiber wiring module 20 includes a first wiring module 21 and a second wiring module 22 symmetrically distributed on the distribution frame 10. The first wiring module 21 and the second wiring module 22 are respectively outward toward the two sides of the distribution frame 10, so that the optical fiber insertion angle and the plane where the panel of the distribution frame 10 is located are at a set angle. The optical fiber wiring module 20 is divided into a first wiring module 21 and a second wiring module 22. The optical fibers on the two groups of wiring modules are respectively led out to the rack from both sides, which can reduce the thickness of the optical fiber bundle, make the bending point of the optical fiber as far away from the optical fiber wiring module 20 as possible, and reduce the bending degree of the optical fiber.

[0033] In an optional embodiment, a plurality of first wiring modules 21 are arranged in parallel, and the angle between the optical fiber insertion angle and the plane where the panel of the distribution frame 10 is located is any angle within a range of 15° to 45°. Figure 2 As shown, the first wiring module 21 is deflected to the right outer side, and the second wiring module 22 symmetrical thereto is deflected to the left outer side, and two groups of symmetrical wiring harnesses are introduced into the cabinet from the front side of the distribution frame 10. When the optical fiber wiring module 20 is pre-tilted, the bending degree of the optical fiber is reduced.

[0034] In a preferred embodiment, the angle between the multiple first wiring modules 21 and the plane where the panel of the distribution frame 10 is located gradually increases from both sides to the middle, and the optical fiber insertion angle and the angle of the plane where the panel of the distribution frame 10 is located are 15° to 45°. In this way, the pre-tilt angle of the optical fiber wiring module 20 near the edge is larger, and the pre-tilt angle of the optical fiber wiring module 20 gradually decreases as it approaches the middle, so that the bending angle of each optical fiber on the wire bundle is similar, and there is no excessive bending of the optical fiber at the bundling location.

[0035] Furthermore, in order to arrange the optical fiber bundles more orderly and facilitate the corresponding search by the staff, the second aspect of the utility model proposes a cable management component, which uses the above-mentioned optical fiber distribution frame, including a cable management frame 30, which is arranged to be fixedly installed on the front side of the distribution frame 10, and can fix the optical fiber cable to the cable management frame 30 and lead it out from both sides of the cable management frame 30.

[0036] Among them, Figure 1 and Figure 4 As shown, the cable management frame 30 is provided with label placement areas 321 corresponding to the number and position of the optical fiber wiring modules 20. The label placement areas 321 are configured to fix the labels 40 on the optical fibers so that the positions of the labels 40 can correspond to the positions of the optical fiber wiring modules 20.

[0037] Generally, in order to identify the optical fiber, a label 40 for identifying the optical fiber is adhered to each optical fiber. When the optical fibers are bundled into bundles, the labels are also squeezed together, making it difficult to match the optical fiber lines and the labels 40 one by one. Therefore, a label placement area 321 corresponding to the number and position of the optical fiber wiring modules 20 on the rear side is set on the front side of the cable management frame 30. After the optical fiber is fixed to the cable management frame 30, the label 40 is also fixed to the label placement area 321 accordingly, so that the staff can match the label 40 with the optical fiber during maintenance at a later stage.

[0038] Specifically, Figure 1 As shown, the cable management frame 30 includes a cable management support 31, a panel 32 and a bracket 33. The cable management support 31 is configured to fix the optical fiber and guide the optical fiber to the cabinet from both sides of the distribution frame 10. The panel 32 is fixed to the front side of the cable management support 31 and is used to install the label 40. The bracket 33 is fixedly installed at both ends of the panel 32 and is used to fix the panel 32 to the front side of the distribution frame 10. The panel 32 and the bracket 33 can both be made of stainless steel plate material, which has high strength and load capacity. The bracket 33 is partially fixed to the distribution frame 10 by screws.

[0039] Furthermore, part of the cable management support 31 can be made of plastic material, and the upper and lower sides and left and right sides of the cable management support 31 are provided with cable grooves for clamping optical fibers, so that the optical fibers are led out from the optical fiber wiring module 20 to both sides in an "L" shape in the cable management support 31. Multiple optical fibers are fixed by the cable grooves without being bundled together, which makes it easier to inspect and maintain any one of the optical fibers.

[0040] like Figure 2 and Figure 3As shown, the cable management support 31 opposite to the first wiring module 21 or the second wiring module 22 includes at least a first support 311 and a second support 312, the first support 311 is located on the outside of the second support 312, and the depth of the cable grooves on the upper and lower sides of the first support 311 is greater than the depth of the cable grooves on the upper and lower sides of the second support 312, so that the optical fiber can be led out to both sides in a staggered manner front and back in the cable management support 31.

[0041] Taking the optical fiber distribution frame 10 with four groups of optical fiber wiring modules 20 as an example, the two groups of optical fiber wiring modules 20 on a single side are respectively provided with a first support 311 and a second support 312, and the depth of the wire groove on the first support 311 located on the outside is greater than the depth of the wire groove on the second support 312 located on the inside, so that the optical fibers on different modules can be staggered and led out from the side in the thickness direction of the cable management frame 30, making the arrangement of the optical fibers more orderly.

[0042] Specifically, Figure 3 As shown, the wire groove includes a first wire groove 301 distributed on the upper and lower sides of the wire management support 31 and a second wire groove 302 distributed on the left and right sides of the wire management support 31, wherein the depth of the second wire groove 302 is equal to the thickness of the wire management support 31, and the depth of the first wire groove 301 gradually increases from the second support 312 to the first support 311.

[0043] During the installation of the optical fiber, the optical fiber located in the outer module is pressed into the first wire groove 301 in advance, and then correspondingly led out from the second wire groove 302, and the optical fibers on each module are prevented from crossing. After the optical fiber located on the outer module is installed, the optical fiber located on the inner module is installed.

[0044] Furthermore, the depth difference between the first wire groove 301 on the first support 311 and the second support 312 is at least greater than the diameter of the optical fiber, so that the optical fibers led out of the second wire groove 302 can be staggered in the thickness direction.

[0045] Preferably, the number of first wire grooves 301 located on the upper and lower sides of the cable management support 31 is equal, so that the two groups of optical fibers distributed vertically in the module can be symmetrically installed on the cable management support 31 from the upper and lower sides for fixation.

[0046] In combination with the above embodiments, an optical fiber wiring module 20 with a set tilted angle is provided on the distribution frame 10, so that the optical fiber plugged on the optical fiber wiring module 20 can be more easily bent outward and guided to the cabinet, thereby reducing the bending degree of the optical fiber and avoiding the problem of poor signal transmission quality caused by excessive bending of the optical fiber. At the same time, a cable management frame 30 is provided on the front side of the distribution frame 10, which can independently restrict each optical fiber on the distribution frame 10 in the cable trough without the need for bundling, and the label of each optical fiber is fixed to the front side of the cable management frame 30, so that the staff can match the label 40 with the optical fiber during maintenance at a later stage.

[0047] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
