[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0036] Reference Figure 1-5 As shown in Figures 8-12, a high-density fiber optic distribution frame of this utility model includes:

[0037] The cabinet has an optical cable inlet hole 1.2 and an optical cable outlet hole 1.3 on the top, and several cable tie holes 1.1 on both sides of the optical cable inlet hole 1.2 and the optical cable outlet hole 1.3; cable trays 9 are provided on both sides of the interior of the cabinet; the cable trays 9 are provided with multiple rows of cable tie bridges 9.4.

[0038] The wiring sub-unit 6 comprises several units arranged parallel to each other inside the cabinet. Each wiring sub-unit 6 includes a wiring sub-unit cover plate 6.1, a wiring sub-frame 6.7, a wiring sub-unit drawer 6.8, and an adapter panel 6.2. The wiring sub-unit cover plate 6.1 is positioned above the wiring sub-frame 6.7. First silent slide rails 6.9 are arranged parallel to each other on both sides of the inner wall of the wiring sub-frame 6.7. The wiring sub-unit drawer 6.8 is slidably connected to the first silent slide rails 6.9. The adapter panel 6.2 is positioned on the wiring sub-unit drawer 6.8 and contains several adapters 6.6. The wiring sub-frame 6.7 also has a first left hanging ear 6.3 and a right hanging ear 6 on both sides. 4. The rear end of the wiring subframe 6.7 is provided with concave and convex holes as the cable entry holes for the MPO optical cable; the wiring subunit cover plate 6.1 is connected to the wiring subframe 6.7 through a three-way opening 6.5, which can be opened by hand without tools, facilitating later maintenance; the rear end of the wiring subframe 6.7 is provided with a cable tie bridge 9.4 as the MPO optical cable fixing area, and the wiring subunit drawer 6.8 is provided with multiple rows of cable tie bridges 9.4 as the MPO optical cable routing area, so that the MPO optical cable can travel along a certain path to the adapter panel 6.2 and terminate with the adapter 6.6 on the adapter panel 6.2; the wiring subunit drawer 6.8 is connected to the wiring subunit frame 6.7 through the first silent slide rail 6.9, realizing its free sliding and facilitating later operations.

[0039] The fiber storage subunit 7 is used to realize the entry of optical cable and large-capacity fiber storage. The fiber storage subunit 7 consists of a fiber storage subunit cover plate 7.1, a fiber storage subframe 7.4, a fiber storage subunit drawer 7.5, a fiber winding tube 7.7, and a wire loop 7.8. The fiber storage subunit cover plate 7.1 is located above the fiber storage subframe 7.4. The inner walls of the fiber storage subframe 7.4 are provided with parallel second silent slide rails 7.6. The fiber storage subunit drawer 7.5 is slidably disposed inside the fiber storage subframe 7.4. The fiber winding tube 7.7 and the wire loop 7.8 are disposed inside the fiber storage subframe 7.4. The fiber storage subframe 7.4 is provided with a second left hanging ear 7.2 and a second right hanging ear 7.3 on both sides.

[0040] The fiber storage unit drawer 7.5 has wire loops 7.8 at its four corners to guide the routing of the MPO optical cable, and a fiber spool 7.7 in the middle to store redundant patch cords. A certain gap is left between the fiber spool 7.7 and the fiber storage frame 7.4 after the drawer is fully pushed in, serving as the inlet and outlet for the MPO patch cords.

[0041] The fiber storage subunit 7 and the wiring subunit 6 are connected by a jumper. One end of the jumper is connected to the adapter on the wiring subunit 6, and the other end is led to the equipment frame after passing through the wire loop 7.8 and the fiber winding tube 7.7.

[0042] By using adapter 6.6 in the distribution subunit 6, high-density connections of the fiber optic distribution frame are achieved, significantly increasing the density of fiber optic connections. The design of the fiber storage subunit 7 enables the storage of excess patch cord lengths, improving the standardization and convenience of fiber optic management and simplifying fiber optic maintenance and operation.

[0043] In this embodiment, four cable trays 9 are provided in the front left, front right, rear left, and rear right sections of the cabinet, namely the front left cable tray 9.1, rear left cable tray 9.2, front right cable tray 9.3, and rear right cable tray 9.4. These are used for the management and maintenance of MPO optical cables after they enter the cabinet. The cable tie bridges 9.4 on the cable trays 9 are used to bind the optical cables. The front left cable tray 9.1 and front right cable tray 9.3 are used for fixing and managing the MPO optical cables coming out of the fiber storage subunit 7 and for leading them out toward the optical cable exit hole 1.3.

[0044] Furthermore, several rectangular holes are provided around the optical cable inlet 1.2 and the optical cable outlet 1.3 for securing the optical cable with straps. The design of these rectangular holes enhances the reliability of the optical cable's fixation and prevents displacement under vibration or external force.

[0045] In this embodiment, the cabinet includes a top panel 1, a bottom panel 2, a side door 3, a front door 4, a rear door 5, and a movable support column 8. The movable support column 8 is positioned between the top panel 1 and the bottom panel 2 to form the cabinet's frame structure. The front door 4 and rear door 5 are connected to the frame structure via door pins, and the side door 3 is connected to the frame structure via snap-fit ​​fasteners. All three doors—front door 4, rear door 5, and side door 3—are detachably connected to the frame structure. The movable support column 8 and frame structure enhance the cabinet's structural stability, ensuring the safe and stable operation of the internal components. The front door 4, rear door 5, and side door 3 are connected to the frame structure via hinges, facilitating the installation, maintenance, and management of the equipment by operators.

[0046] Furthermore, the movable column 8 includes a front left column 8.1, a rear left column 8.2, a front right column 8.3, and a rear right column.

[0047] like Figure 6 and 7As shown, the front left column 8.1 and the rear left column 8.2, as well as the front right column 8.3 and the rear right column, are connected by supports 13, and each support 13 has mounting holes 13.1. Three supports 13 are provided on each of the left and right sides of the cabinet from top to bottom. The front left column 8.1, rear left column 8.2, front right column 8.3, and rear right column can be adjusted in front-to-back distance via the mounting holes 13.1 on the supports 13 to accommodate equipment of different depths. Each column has a slot for connection to the mounting holes 13 on the supports 13 using a four-piece set of screws. The design of the supports 13 improves the flexibility of the cabinet structure, facilitating adjustments to the internal layout according to actual needs.

[0048] In this embodiment, the cabinet is equipped with a front door 4, a rear door 5, and a side door 3. The front door 4 is a single door, and the rear door 5 is a double door. The design of the front door 4 being a single door and the rear door 5 being a double door allows operators to choose different doors to operate as needed, improving operational convenience.

[0049] In this embodiment, the cable tray 9 includes a first tray and a second tray, which are arranged in a stepped configuration. The stepped configuration of the cable tray 9 improves the flexibility and adaptability of fiber optic cabling.

[0050] In this embodiment, the first channel is provided with a clearance groove. When the optical fiber passes through the first channel, the clearance groove ensures that the optical fiber can safely bypass the support, avoiding damage to the optical fiber caused by the physical obstruction of the support 13. This design not only improves the durability and reliability of the optical fiber, but also makes optical fiber cabling more flexible and efficient.

[0051] In this embodiment, the distribution subframe 6.7 includes an optical cable entry area 6.10, an optical cable routing area 6.11, and an optical cable fixing area 6.12. This design facilitates standardized management of optical fibers and improves the standardization and convenience of optical fiber management.

[0052] The routing of the high-density fiber optic distribution frame based on the above structure is as follows: The MPO optical cable, originating from the MODF main distribution frame equipment side, enters the cable tray 9 through the cable inlet 1.2, is bundled and secured, and then enters the cable fixing area 6.12 from the cable inlet area 6.10 at the rear of the distribution subunit 6. It is then fixed in the cable fixing area 6.12, and proceeds to the cable routing area 6.11, where it is inserted into the adapter 6.6 via a specific path. Finally, via an MPO patch cord, the fiber storage subunit 7, used in conjunction with the distribution subunit 6, leads one end of the MPO patch cord to the equipment rack.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
