Description

Technical Field

[0001] This utility model relates to the technical field of communication fiber optic laying and installation equipment, and in particular to a rack-mounted optical splitter. Background Technology

[0002] In fiber-to-the-home (FTTH) passive optical networks (PON), optical splitters play a crucial role, and with the continuous development of network communication, the demand for the number of optical paths splitters can increase. For example, rack-mounted optical splitters can be installed in 19-inch standard integrated distribution cabinets or network cabinets to achieve centralized splitting and capacity expansion of optical signals. They can be deployed on the OLT (Optical Line Terminal) side and distribute backbone optical signals to multiple user terminals through standardized interfaces (such as SC / LC / FC). They are suitable for passive optical network architectures such as EPON and GPON and are the most commonly used splitters in FTTH applications.

[0003] Rack splitters are available in various models, including 1×2, 1×4, 1×8, 1×16, and 1×32. Currently, based on the structure of the configuration with fiber optic connectors, the input and output terminals of rack splitters are built into the housing. When connecting to upstream servers and other terminal equipment via fiber optic connectors, it is mainly achieved through the connection and cooperation of flanges and fiber optic connectors. Moreover, the connectors of the fiber optic connectors cannot be replaced at will. When a connector is damaged, it is necessary to replace or modify the splitter to solve the problem. Therefore, if the optical path of the splitter is not abnormal but only the connector is abnormal, replacing the entire splitter would actually be a huge waste. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a rack-mounted optical splitter that allows for the individual replacement of faulty fiber optic connectors, thereby helping to improve the utilization rate of the optical splitter.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a rack-mounted optical splitter, including a fixedly connected chassis and a fixing plate, wherein the fixing plate also serves as a flange mounting plate, and a plurality of fiber optic flanges are arranged and installed through the fixing plate. The chassis is a box-type structure with openings at the top and one side. A box plate is detachably encapsulated at the top opening of the chassis, and the fixing plate is encapsulated at the side opening of the chassis. An optical splitter module is fixed inside the chassis. Common fiber optic patch cords are detachably connected to each of the optical splitter modules and each of the fiber optic flanges. A spare fiber optic patch cord is also provided on the side of the optical splitter module inside the chassis, and a patch cord stacking device for use with the spare fiber optic patch cord is installed inside the chassis.

[0006] As a preferred technical solution, the patch cord stacking device includes two patch cord stacking seats arranged opposite each other. The close sides of the two patch cord stacking seats are respectively provided with patch cord stacking slots, and the patch cord stacking slots on the two patch cord stacking seats are arranged in a one-to-one correspondence. The spare optical fiber patch cord is locked between the corresponding patch cord stacking slots on the two patch cord stacking seats.

[0007] As a preferred technical solution, the top of the jumper cable holder is flush with the top of the chassis.

[0008] As a preferred technical solution, the spare fiber optic patch cord is stacked at least once in the corresponding patch cord stacking slot.

[0009] As a preferred technical solution, at least one set of spare fiber optic patch cords is installed according to the types of commonly used fiber optic patch cords.

[0010] As a preferred technical solution, a jumper cable placement and wiring device is also installed inside the chassis on the side of the jumper cable placement device.

[0011] As a preferred technical solution, the patch cord placement and cabling device includes a patch cord cabling board fixedly installed in the chassis, a cabling adjustment hole is provided through the patch cord cabling board, and two movable cabling posts for supporting the spare fiber optic patch cord are limited and slidably assembled in the cabling adjustment hole.

[0012] As a preferred technical solution, a fixed wiring post is fixedly installed on the chassis corresponding to each of the jumper bar slots.

[0013] As an improvement to the above technical solution, the chassis is provided with directional wiring posts on the inner side of each of the optical fiber flanges and on the lower side of the connection position between the optical splitter module and the commonly used optical fiber patch cord.

[0014] Due to the adoption of the above technical solution, this utility model has the following beneficial effects: When a commonly used fiber optic patch cord in a rack-mounted optical splitter fails and needs to be replaced, the box panel is disassembled, and a spare fiber optic patch cord of the corresponding model is taken out from the patch cord stacking device for replacement. Then the box panel is reassembled, which helps to improve the utilization rate of the optical splitter, reduce the waste of the optical splitter, and lower its maintenance cost; the spare fiber optic patch cord is arranged in the box through the patch cord stacking device, making the layout inside the box neat and preventing mutual interference between lines.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0022] like Figures 1 to 4 As shown, the rack-mounted optical splitter enables fiber optic connection to the home. It includes a fixedly connected chassis 1 and a mounting plate 2, with the mounting plate 2 also serving as a flange mounting plate. Several fiber optic flanges 3 for fixing and connecting optical cables are arranged through the mounting plate 2. Fixing bolts are provided at both ends of the mounting plate 2, which can realize the installation and fixation of the entire optical splitter.

[0023] In this embodiment, the chassis 1 is a box-type structure with openings at the top and one side. A detachable panel 4 is installed at the top opening of the chassis 1, and a fixing plate 2 is installed at the side opening of the chassis 1. The panel 4, the chassis 1, and the fixing plate 2 cooperate to encapsulate the fiber optic connection components inside the chassis 1. Furthermore, the panel 4 can be assembled to the chassis 1 using bolts or screws. Disassembling the panel 4 fully exposes the internal components, facilitating inspection and maintenance.

[0024] An optical splitter module 5 is fixed inside the chassis 1. Common fiber optic patch cords 6 are detachably connected to each of the fiber optic flanges 3. Through the cooperation of the optical splitter module 5, the common fiber optic patch cords 6, and the fiber optic flanges 3, fiber optic signal input, splitting, and output to the user are achieved. A spare fiber optic patch cord 7 is also provided on the side of the optical splitter module 5 inside the chassis 1. The spare fiber optic patch cord 7 is used to replace one or more of the common fiber optic patch cords 6 when they malfunction, thus avoiding the need to replace the optical splitter and significantly reducing maintenance costs. Both the common fiber optic patch cords 6 and the spare fiber optic patch cord 7 are composed of fiber optic connectors, optical cables, etc., and their specific structure and working principle are well-known in the technical field and will not be described in detail here.

[0025] In this embodiment, a patch cord securing device is installed inside the chassis 1 to work with the spare fiber optic patch cord 7. This device secures the spare fiber optic patch cord 7, ensuring it remains relatively fixed to the chassis 1 in its standby state, thus maintaining the neatness of the layout within the chassis 1. Specifically, the patch cord securing device includes two patch cord securing seats 8 arranged opposite each other. Patch cord securing slots 9 are respectively provided on the proximal sides of the two securing seats 8, and these slots 9 are arranged in a one-to-one correspondence. The spare fiber optic patch cord 7 is secured between the corresponding slots 9 on the two securing seats 8. The width of the slot 9 can be interference-fitted with the fiber optic connector at the end of the spare fiber optic patch cord 7, allowing the spare fiber optic patch cord 7 to be automatically secured in its standby state. In use, a finger can be inserted into the gap between the spare fiber optic patch cord 7 and the slot 9, and pulled out with slight force; this is simple and convenient.

[0026] The top of the patch cord holder 8 is flush with the top of the chassis 1. After the chassis 4 is installed, the port of the patch cord slot 9 can be sealed to prevent the spare fiber optic patch cord 7 from falling off during transportation or installation. The patch cord holder 8 also provides some support to the chassis 4, enhancing its compressive strength. At least one layer of spare fiber optic patch cord 7 is stacked in the corresponding patch cord slot 9, depending on the depth of the slot (specifically, the depth of the chassis 1). For multi-channel optical splitters, the number of commonly used fiber optic patch cords 6 is large, while the capacity of the chassis 1 is limited. Therefore, two or more spare fiber optic patch cords 7 can be stacked in the same patch cord slot 9 to increase the spare capacity. To save on configuration costs, at least one set of spare fiber optic patch cords 7 can be installed according to the type of commonly used fiber optic patch cord 6. When the spare fiber optic patch cord 7 is used up, it needs to be replenished promptly to ensure wired availability for the next use.

[0027] like Figure 3 As shown, a patch cord arranging and wiring device is also installed inside the chassis 1 on the side of the patch cord arranging device. This device is used to more systematically route the longer spare fiber optic patch cords 7, making the area inside the chassis 1 more organized. Specifically, the patch cord arranging and wiring device includes a patch cord wiring board 10 fixedly installed inside the chassis 1. A wiring adjustment hole 11 is provided through the patch cord wiring board 10. Two movable wiring posts 12 for supporting the spare fiber optic patch cords 7 are limited and slidably fitted inside the wiring adjustment hole 11. The longer spare fiber optic patch cords 7 are straddled on one or two movable wiring posts 12 within the same wiring adjustment hole 11. By changing their direction, they are kept in a stretched state to prevent tangling with other wires and to minimize contact between the wires. The movable wiring posts 12 can slide along the wiring adjustment hole 11 to change their position, so as to adjust them to a position suitable for routing the spare fiber optic patch cords 7 without contacting other lines.

[0028] In this embodiment, fixed wiring posts 13 can also be fixedly installed on the chassis 1 corresponding to each of the jumper cable mounting slots 9. The fixed wiring posts 13 can redirect the routing of the spare fiber optic jumper 7, making the cable change direction gentler and preventing wear caused by contact with the jumper cable mounting base 8, thus helping to protect the cable. Similarly, redirection wiring posts 14 can also be provided inside the chassis 1, on the inner side of each fiber optic flange 3 and below the connection position between the optical splitter module 5 and the commonly used fiber optic jumper 6, to protect the wiring of the commonly used fiber optic jumper 6.

[0029] When a commonly used fiber optic patch cord 6 in a certain path of this utility model fails and needs to be replaced, the box panel 4 is disassembled, and a spare fiber optic patch cord 7 of the corresponding model is taken out from the patch cord stacking device for replacement. Then the box panel 4 is reassembled, which helps to improve the utilization rate of the optical splitter, reduce the waste of the optical splitter, and lower its maintenance cost.

[0030] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
