Description

Technical Field

[0001] This application relates to the field of optical fiber communication technology, and in particular to a convenient high-density multifunctional optical fiber distribution box. Background Technology

[0002] As a key piece of equipment in communication equipment rooms and data centers, fiber optic distribution boxes are mainly used for the distribution, scheduling and management of optical fibers. They also include functions such as connection, switching, protection and expansion. Their performance directly affects the efficiency of cabling, the convenience of maintenance and the space utilization rate.

[0003] In related technologies, referring to the prior art document CN223006336U, current fiber optic distribution boxes can create a larger operating space for cabling personnel through built-in folding mechanisms. However, due to the occupation of structures such as back panels, door panels, and locks, their depth often exceeds 270mm, making them unsuitable for standard communication cabinets with a minimum depth of 300mm (effective utilization depth is only 260mm), thus affecting space utilization and deployment flexibility.

[0004] Existing fiber optic distribution boxes have the following problems: they are too deep and cannot be adapted to shallow cabinets, resulting in wasted space that cannot meet the needs of modern high-density fiber optic cabling. With the rapid development of fiber optic communication technology, the demand for fiber optic capacity in communication equipment rooms and data centers has increased dramatically. Utility Model Content

[0005] To improve adaptability, this application provides a convenient high-density multi-functional fiber optic distribution box.

[0006] This application provides a convenient, high-density, multi-functional fiber optic distribution box using the following technical solution: A portable, high-density, multi-functional fiber optic distribution box includes a box body, slide rails, mounting ears, a front cable management panel, and an integrated tray. The box body is compatible with 19-inch standard cabinets and has a depth not exceeding 255mm. The integrated tray is slidably connected to the box body via the slide rails and can be pulled forward. The front cable management panel is installed at the front end of the integrated tray via a locking structure and can be flipped downwards. The mounting ears are fixed to both sides of the box body to suspend the box body.

[0007] By adopting the above technical solutions, the enclosure can be adapted to shallow cabinets, ensuring seamless access to existing data centers, communication equipment rooms and other infrastructure, effectively improving space utilization and deployment flexibility compared to traditional fiber optic distribution boxes.

[0008] Preferably, the enclosure contains a plurality of integrated trays stacked vertically at intervals, wherein each 1U height can accommodate at least three integrated trays, and each integrated tray can accommodate up to 48 LC ports.

[0009] By adopting the above technical solutions, fiber density is increased, cabling space is saved, and the needs of high-density fiber optic cabling are met.

[0010] Preferably, the enclosure adopts a symmetrical design to accommodate four wiring modes: left-in-right-out, right-in-left-out, left-in-out, and right-in-out.

[0011] By adopting the above technical solution, there is no need to modify the cabinet structure or add extra accessories, and users can flexibly choose the fiber optic path according to the actual scenario.

[0012] Preferably, the slide rail is provided with an intermediate position. After the integrated tray slides along the slide rail to the intermediate position, it lifts the front cable management plate upward to release the lock.

[0013] By adopting the above technical solution, the tray can be used for specific operations while it is partially pulled out, reducing the possibility of it taking up too much space when fully pulled out.

[0014] Preferably, the inner walls on both sides of the integrated tray are provided with sliding grooves that are adapted to the side walls of the front cable management plate. The front cable management plate slides and engages with the sliding grooves. After the front cable management plate is pulled out of the bottom plate of the integrated tray along the sliding grooves, it can be flipped downwards to expose the adapter on the integrated tray.

[0015] By adopting the above technical solution, the front cable management board is flipped down, creating more operating space for cabling personnel, thereby improving operating efficiency.

[0016] Preferably, the integrated tray supports hot-swappable operation.

[0017] By adopting the above technical solution, operators can replace parts without shutting down the system or cutting off the power, thus improving maintenance convenience.

[0018] Preferably, the mounting ears are used to fix the enclosure to the cabinet by means of left and right pins and non-removable screws.

[0019] By adopting the above technical solution, double fixation is achieved, improving fastening force and anti-loosening properties.

[0020] Preferably, the enclosure also includes optional accessories fixed to the left and right sides of the enclosure. Each of the left and right sides of the enclosure is provided with multiple press-fit nuts for installing the optional accessories.

[0021] By adopting the above technical solution, the optional accessories can be quickly installed.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a portable, high-density, multi-functional fiber optic distribution box. (Refer to...) Figure 1-3 A convenient high-density multi-functional fiber optic distribution box includes a box body 1, a slide rail 33, a hanging ear 2, a front cable management plate 31, and an integrated tray 3. The box body 1 is compatible with a 19-inch standard cabinet and its depth is controlled within 255mm. The integrated tray 3 is slidably connected to the box body 1 through the slide rail 33 and can be pulled forward. The front cable management plate 31 is installed on the front end of the integrated tray 3 through a locking structure (not shown in the attached figure) and can be flipped downward. The hanging ear 2 is fixed to both sides of the box body 1 to suspend the box body 1.

[0030] Correspondingly, the enclosure 1 is compatible with shallow racks, reducing the rack's footprint and allowing more devices to be deployed within a single rack, thus increasing the unit space capacity. The integrated tray 3, through its sliding and pull-out design with the slide rail 33, allows operators to quickly access the rear fiber optic interface, enabling flexible cabling and expansion of dense fiber optic cables. The front cable management board 31 can be flipped down to facilitate temporary fixing of jumpers during operation, reducing clutter. The side mounting ears 2 are designed to support rack installation or wall mounting, adapting to narrow spaces.

[0031] Therefore, the 255mm depth design of the enclosure 1 can be seamlessly integrated into existing data centers, communication equipment rooms and other infrastructure without the need for customized cabinets or space modification. Compared with traditional fiber optic distribution boxes, it effectively improves deployment flexibility and adaptability to multiple scenarios. The modular structure of the integrated tray 3 combined with the hanging ear 2 can support tool-less loading and unloading, which is convenient for later maintenance or upgrade expansion. The device takes into account space utilization, operation efficiency and maintenance convenience, and meets the high-efficiency operation and maintenance needs of modern fiber optic networks.

[0032] Specifically, in this embodiment, multiple integrated trays 3 are vertically stacked and spaced apart inside the enclosure 1. Each 1U height can accommodate three integrated trays 3, and each integrated tray 3 can accommodate up to 48 LC ports. In a single enclosure 1 with the same structure from 1U to 6U: 1U can support 144 LC ports; 2U can support 288 LC ports; 3U can support 432 LC ports; 4U can support 576 LC ports; 5U can support 720 LC ports; and 6U can support the management and distribution of 864 LC ports.

[0033] Therefore, increasing fiber density saves cabling space by increasing the number of fibers per unit space, thereby increasing the capacity of a single rack and reducing the total number of racks. This indirectly reduces patch cord error rates and the power and cooling costs of data centers, meeting the future expansion needs of the network.

[0034] Furthermore, the LC interface adopts a small square duplex design with a single core size of only 1.25mm. Its compact nature allows the integrated tray 3 to integrate more ports in a limited space. The 48-core configuration is achieved through modular arrangement, supports 10 Gigabit / 40G networks, and has lower insertion loss than the SC interface.

[0035] On the other hand, refer to Figure 4 The mounting ears 2 use left and right pins 22 and captive screws 23 to fix the enclosure 1 to the cabinet. The captive screws 23 are usually made of high-quality carbon steel or stainless steel and have a self-tapping and anti-slip thread design. They can maintain locking force on smooth surfaces or under severe vibration, reducing the risk of accidental fall-off. The knurled surface of the captive screws 23 also allows operators to quickly disassemble and maintain them by hand.

[0036] Furthermore, the non-loosening screw 23 is also corrosion-resistant and has a service life far longer than ordinary screws. When used in conjunction with the pin 22 to achieve double fixing, it effectively improves the installation stability and anti-loosening performance of the housing 1.

[0037] Meanwhile, the enclosure 1 adopts a symmetrical design to accommodate four cabling modes: left-in, right-out, right-in, left-out, and right-out. This can match different incoming cable direction requirements from the data center to the 5G base station. All four modes support front-end operation with low operating space requirements. Users do not need to modify the structure of enclosure 1 or add extra accessories. The fiber optic path can be flexibly adjusted according to the actual scenario such as the layout of the equipment room, thereby reducing the crossing and bending of cables, reducing the risk of signal attenuation, and facilitating direct connection and maintenance positioning of equipment.

[0038] In the process described above, the slide rail 33 is equipped with an intermediate stop, which is located between the fully extended position and the initial position. As a temporary positioning point during operation, it can ensure that the integrated tray 3 stops accurately when sliding and forms a stable support between the front end of the integrated tray 3 and the front cable management plate 31. This allows the integrated tray 3 to perform specific operations in a partially extended state, reducing the situation where the fully extended tray occupies too much space. At the same time, the intermediate stop limits the sliding range of the integrated tray 3, reducing the situation where the cable is stressed or the equipment falls off due to excessive pulling, and reducing the risk of space conflict when adjacent trays are operated.

[0039] Furthermore, the front cable management plate 31 remains stable in the non-operating position when locked to reduce accidental tipping. The inner walls of both sides of the integrated tray 3 are provided with grooves 32 that are adapted to the side walls of the front cable management plate 31. The front cable management plate 31 slides and engages with the grooves 32. After the integrated tray 3 slides along the slide rail 33 to the middle position, the front cable management plate 31 is lifted upward to release the locked state. Then, the front cable management plate 31 is pulled out of the bottom plate of the integrated tray 3 along the groove 32 and flipped downward to expose the adapter on the integrated tray 3.

[0040] Therefore, operators can directly expose the fiber optic adapter area without fully removing the integrated tray 3, thereby shortening the patch cord or splice operation time, effectively improving operation efficiency and maintenance convenience, realizing efficient maintenance and safe operation of high-density fiber optic distribution boxes, and providing a solution that combines flexibility and reliability for modern optical networks.

[0041] Correspondingly, after the operator has disassembled, installed or maintained the cable management plate 31, rotate it upwards to the stop on the bottom plate of the integrated tray 3, and then push the cable management plate 31 inwards until the lock is in place. This will re-lock the cable management plate 31 and the integrated tray 3. After the integrated tray 3 is completely pushed into the box 1, it will return to its initial state.

[0042] On the other hand, the integrated tray 3 also supports hot-swappable operation. The hot-swappable technology ensures the system is stable and reliable when operating under power through multiple protections such as hardware protection circuits and software plug-and-play protocols. Operators can replace parts without shutting down the system or cutting off the power, which improves the convenience and safety of maintenance.

[0043] In addition, this embodiment also includes optional accessories 4 fixed to the left and right sides of the housing 1. Optional accessories 4 include left and right output optical cable buffer plates and input optical cable guide plates, as well as left and right universal input optical cable guide plates, input optical cable right angle guide plates, side right angle panel strips, horizontal optical cable fixing plates or vertical optical cable fixing plates, etc., which can generally provide functions such as fixing, protection, path management and radius control for optical fibers.

[0044] Meanwhile, four press-fit nuts 11 are fixed on each of the left and right sides of the housing 1 to provide a standardized installation interface for fixing the optional accessory 4. Its embossed tooth design forms a locking mechanism with the plate through plastic deformation, eliminating the need for additional bolts, effectively improving installation efficiency and enabling the rapid installation of the optional accessory 4.

[0045] Furthermore, the flat back of the press-fit nut 11 reduces the risk of interference caused by traditional welding or bolt protrusions, making it particularly suitable for space-constrained scenarios such as chassis and cabinets. Its excellent reusability allows it to maintain most of the locking force after multiple disassemblies and reassemblies, making it easy to replace accessories as needed.

[0046] The implementation principle of a convenient high-density multi-functional fiber optic distribution box in this application embodiment is as follows: The 255mm depth design of the box body 1 can be adapted to shallow cabinets, and can be seamlessly connected to existing data centers, communication equipment rooms and other infrastructures without the need for customized cabinets or space modification. Compared with traditional fiber optic distribution boxes, it effectively improves deployment flexibility and multi-scenario adaptability. The modular structure of the integrated tray 3 combined with the hanging ears 2 can support tool-less loading and unloading, which is convenient for later maintenance or upgrade expansion. This device takes into account space utilization, operation efficiency and maintenance convenience, and meets the high-efficiency operation and maintenance needs of modern fiber optic networks.
