Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, and in particular to a multimode 1-to-7 optical splitter. Background Technology

[0002] As the core passive device for distributing optical signal power in optical fiber communication systems, optical splitters play a crucial role in fiber-to-the-home, data centers, and various optical transmission networks. The basic function of an optical splitter is to evenly distribute a single-input optical signal to multiple output channels.

[0003] Currently, the design of optical splitter products on the market focuses on the performance of internal optical chips, while the design of external physical structures is relatively simplified. These optical splitters simply encapsulate precision optical components in simple protective boxes. In actual engineering applications, the installation and fixing methods of these boxes are relatively simple. They are either fixed to the rack or wall directly through the box with screws, or placed directly on the cable tray of the cabinet or on the workbench.

[0004] However, this overly simplified structural design has gradually revealed inherent defects in actual deployment and long-term maintenance. For scenarios requiring fixed use, the direct screw fixing method makes the installation process cumbersome. More seriously, when the equipment malfunctions and needs repair or upgrade, maintenance personnel must completely disassemble the entire device, which is extremely inconvenient, especially in cabinet environments with dense cabling and limited space, greatly reducing maintenance efficiency. For scenarios where the device is placed directly, the existing splitter box is lightweight and has poor structural stability. During daily maintenance or surrounding cabling construction, it may shift or tip over due to accidental contact. This not only causes the fiber optic connector to be stressed, resulting in signal attenuation or interruption, but also directly damages the delicate internal optical chips due to drops.

[0005] Therefore, this utility model proposes a multimode one-to-seven optical splitter to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of cumbersome installation and fixing methods, inconvenience for subsequent maintenance, poor structural stability, and insufficient impact and drop resistance of existing multimode 1-to-7 optical splitters, this utility model aims to provide a multimode 1-to-7 optical splitter with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a multimode 1-to-7 optical splitter, including a hollow sealed box, a multimode chip disposed in the inner cavity of the sealed box, and a support mechanism for mounting the sealed box.

[0008] The support mechanism includes a base, the top surface of which is integrally formed with a groove and a limiting strip extending along the length of the groove and protruding from the bottom of the groove.

[0009] Furthermore, a long groove is provided on the bottom wall of the sealed box that matches the base. The sealed box aligns and engages with the long groove and the limiting strip to form a sliding connection with the base that is precise and easy to assemble and disassemble. A counterweight can also be detachably fixed to the top of the inner wall of the sealed box, while multiple anti-collision strips are fixedly connected to the outer wall.

[0010] Preferably, one end of the main line is connected to the main connector, and the other end passes through the sealed box wall and is connected to the input end of the multimode chip; multiple branch lines are led out from the output end of the multimode chip in an array through connector plugs and are respectively connected to the fiber optic connectors, and the main connector and fiber optic connectors are both located on the outside of the sealed box, which facilitates the plugging and unplugging of external optical fibers.

[0011] Preferably, the side wall of the sealed box is provided with an opening for inspecting the multimode chip. The opening is detachably sealed and shielded by a sealing side plate. To enhance environmental resistance, the sealed box is made of flame-retardant and high-temperature resistant engineering plastic, while the sealing side plate is made of PPS engineering plastic with strong flame retardancy and moisture resistance.

[0012] Preferably, in order to flexibly adapt to the counterweight requirements of different scenarios, the counterweight block is detachably fixed to the top of the inner wall of the sealed box by bolts or buckles, and the user can install or remove the counterweight block according to the stability requirements of the equipment placement platform.

[0013] Preferably, in order to prevent the sealed box from accidentally coming off during sliding installation, a baffle is integrally formed at one end of the sliding groove of the base. The baffle is used to finally limit and block the sliding sealed box, ensuring the stability after installation.

[0014] Preferably, in order to provide more comprehensive cushioning protection, the anti-collision strip is made of elastic rubber or silicone material and is fixed to the various corners and side centers of the sealed box body by adhesive or embedding, which are prone to impact, and can effectively absorb impact energy when the equipment is accidentally dropped.

[0015] Preferably, in order to ensure the uniformity and high efficiency of optical signal distribution, the multimode chip is a multimode planar optical waveguide chip with high-precision optical path design.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting up a support mechanism and opening a sliding groove and a limiting strip on the base of the support mechanism, slides and engages with the long groove at the bottom of the sealing box, so that the sealing box can be quickly installed on the base or removed from the base, solving the problem of cumbersome installation process and difficult disassembly during later maintenance of optical splitters in the prior art.

[0017] 2. This utility model increases the overall weight by setting a detachable counterweight inside the sealed box, and sets an anti-collision strip made of elastic material on the outside of the sealed box. This solves the problems of similar devices in the prior art being unstable due to their light weight, easily being accidentally touched, and lacking effective cushioning protection when falling, which leads to easy damage to the internal chip.

[0018] 3. This utility model solves the problem that some optical splitters in the prior art have reduced equipment reliability due to insufficient performance of the shell material, which makes it difficult to adapt to harsh working conditions such as high temperature and humidity. This is achieved by using flame-retardant and high-temperature resistant engineering plastic to make the sealed box body and using moisture-proof and insulating engineering plastic to make the sealed side plate.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example:

[0022] Please refer to Figures 1 to 4 This utility model provides a multimode 1-to-7 optical splitter, which aims to solve the problems of unstable placement, poor protection performance, and cumbersome installation and maintenance processes of existing optical splitters due to their simple structure.

[0023] like Figures 1 to 4 As shown, the multimode 1-to-7 optical splitter includes a hollow sealed box 1 and a support mechanism 2 slidably connected to the sealed box 1. The sealed box 1 serves as the main body to accommodate the core component of the optical path conversion, while the support mechanism 2 is used to stably install and fix the sealed box 1. The support mechanism 2 includes a base 204, the top surface of which is integrally formed with a groove 203 and a limiting strip 202 extending along the length of the groove 203 and protruding from the bottom of the groove 203. The bottom wall of the sealed box 1 that cooperates with the base 204 is provided with a corresponding elongated groove 201. During installation, the sealed box 1 aligns and engages with the elongated groove 201 and the limiting strip 202, so that the two sides of the bottom wall of the sealed box 1 can be slidably accommodated within the groove 203.

[0024] To enhance the overall structural protection and operational stability, a counterweight 5 is detachably fixed to the top of the inner wall of the sealed box 1, and multiple anti-collision strips 4 are fixedly connected to the outer wall of the sealed box 1. An opening is provided on the side wall of the sealed box 1, and the opening is detachably sealed and shielded by a sealing side plate 3. A multimode chip 6 is fixedly installed in the inner cavity of the sealed box 1. One end of the main line 10 is connected to a main connector 11, and the other end passes through the wall of the sealed box 1 and is connected to the input end of the multimode chip 6. The input ends of multiple branch lines 8 are connected to the output ends of the multimode chip 6 through multiple connector plugs 7, and the output ends of the branch lines 8 are respectively connected to fiber optic connectors 9.

[0025] Please refer to Figure 1 , Figure 2 and Figure 4 The base 204 of the support mechanism 2 has an integrally formed sliding groove 203 with an inverted trapezoidal cross section on the top surface along the central axis direction, and a limiting strip 202 extending along the entire length of the sliding groove 203 is protruding on the center line of the bottom of the sliding groove 203; a baffle is also integrally formed at one end of the sliding groove 203, and the height of the baffle is higher than the bottom surface of the sliding groove 203; at the same time, a long groove 201 that matches the shape and size of the limiting strip 202 is correspondingly opened on the bottom wall of the sealing box 1, and sliding edges that can be embedded in the sliding groove 203 are formed on both sides of the long groove 201.

[0026] The sliding edge of the sealing box 1 is engaged in the groove 203 of the base 204. At the same time, the long groove 201 is fitted and accommodates the limiting strip 202, ensuring the directional accuracy of the sealing box 1 when it is slidably installed along the groove 203. The baffle plate plays the final limiting and blocking role for the sliding sealing box 1, preventing it from accidentally sliding out of the base 204.

[0027] Please refer to Figure 1 and Figure 4 The inner wall of the sealed box 1 is detachably fixed with a counterweight 5 by bolts or clips. The counterweight 5 significantly increases the overall weight of the sealed box 1, thereby improving its stability when placed and effectively preventing displacement or tipping due to accidental contact. On the outer wall of the sealed box 1, multiple anti-collision strips 4 made of elastic rubber or silicone are fixed by adhesive or embedding. These anti-collision strips 4 can absorb most of the impact energy when the sealed box 1 is impacted or falls, and play an effective buffering protection role for the box itself and the multimode chip 6 inside.

[0028] As a preferred embodiment, please refer to Figure 3 To achieve complete transmission of optical signals, this solution also includes a main line 10, multiple branch lines 8, a main connector 11, multiple connector plugs 7, and multiple fiber optic connectors 9. One end of the main line 10 is connected to the main connector 11, and the other end passes through the wall of the sealed box 1 and is electrically connected to the input end of the multimode chip 6. The input ends of the multiple branch lines 8 are electrically connected to the multiple output ends of the multimode chip 6 in an array through the connector plugs 7, and the output ends of the branch lines 8 are connected to the fiber optic connectors 9 respectively. The main connector 11 and the fiber optic connectors 9 are both located outside the sealed box 1.

[0029] As another preferred embodiment, to enhance the sealing performance, durability, and ease of internal maintenance of the equipment, please refer to... Figure 4 The side wall of the sealed box 1 is provided with an opening for inspection or replacement of the multimode chip 6. The opening is detachably sealed and shielded by a sealing side plate 3 of a suitable size. To adapt to the complex industrial environment, the main body of the sealed box 1 is preferably injection molded from engineering plastic with good flame retardant properties and high temperature resistance, while the sealing side plate 3 is preferably made of PPS engineering plastic with strong flame retardant ability, moisture resistance, non-absorbency and excellent insulation.

[0030] As another preferred embodiment, in order to achieve efficient and uniform distribution of optical signals, please refer to... Figure 3 The multimode chip 6 is preferably a multimode chip 6 fabricated using planar optical waveguide technology. The chip integrates an optical path designed by high-precision photolithography, which can evenly distribute the energy of the single optical signal input from the main line 10 to multiple output channels, thereby ensuring that the optical power output by each branch line 8 is basically consistent.

[0031] Working principle: During installation, the construction personnel first fix the base 204 of the support mechanism 2 to a predetermined position on the wall, cabinet, or floor using screws or adhesive; then, the sealing box 1 is picked up, and the long groove 201 is aligned with the protruding limiting strip 202 on the base 204, and slid along the direction of the slide groove 203; under the precise guidance of the limiting strip 202, the sealing box 1 slides smoothly into the slide groove 203 until it is stopped by the baffle at the end of the slide groove 203, at which point the installation is complete; due to the presence of the counterweight 5, the installed sealing box 1 has a stable center of gravity and is not easily moved by accidental touch; when it is necessary to inspect or replace the internal multimode chip 6, simply slide the sealing box 1 out in the opposite direction along the slide groove 203, the whole process does not require disassembling the base 204, and the operation is extremely convenient; During signal transmission, external optical signals are input into the main line 10 through the main connector 11 and transmitted along the main line 10 to the multimode chip 6 inside the sealed housing 1. The multimode chip 6 uses its internally preset high-precision optical path to couple the optical signals into the corresponding branch lines 8 through the connector 7. The signals are transmitted along their respective branch lines 8 and output to multiple different downstream terminal devices through the fiber optic connector 9 at the end. If the device is accidentally dropped or collided during use, the anti-collision strip 4 fixed on the outside of the sealed housing 1 will first contact the impact surface. The elastic deformation of the anti-collision strip 4 will absorb most of the impact energy, thereby protecting the internal sealed housing 1 and the precision multimode chip 6 from damage.
