Description

Technical Field

[0001] The present invention relates to the field of optical wavelength division multiplexing device testing apparatuses, and more particularly to a testing apparatus for a multi-channel optical wavelength division multiplexing device. Background Art

[0002] A multi-channel optical wavelength division multiplexing device is a device used to implement optical wavelength division multiplexing. It can multiplex optical signals of multiple different wavelengths onto a single optical fiber for transmission, thereby achieving high-capacity and high-speed optical communication.

[0003] Specifically, the multi-channel optical wavelength division multiplexing device combines optical signals of different wavelengths into a single light beam through a multiplexer, and then transmits it through a single optical fiber. At the receiving end, a demultiplexer is used to separate the optical signals of different wavelengths, and then receive and process them. In this way, simultaneous transmission of optical signals on multiple channels can be achieved, greatly improving the transmission capacity and utilization rate of the optical fiber.

[0004] Testing of multi-channel optical wavelength division multiplexing devices includes static testing, dynamic testing, testing of insertion loss, testing of temperature characteristics, etc. Currently, relevant testing can be achieved through a multi-channel optical wavelength division multiplexing device tester. For example, a wavelength division multiplexing optical module testing system disclosed in the utility model with the publication number CN215378923U.

[0005] However, in the existing wavelength division multiplexing optical module testing system for the interface where two optical elements need to be connected, the existing solutions are either only connected through the interface. In this case, the connection point of the optical wire is prone to bending, affecting the performance of the optical wire; or a relatively long plug-in tube is set, resulting in high structural costs and easy bending of the plug-in tube during transportation, causing damage. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above-mentioned defects in the existing wavelength division multiplexing optical module testing system, where for the interface where two optical elements need to be connected, it is only connected through the interface. In this case, the connection point of the optical wire is prone to bending, affecting the performance of the optical wire; if a relatively long plug-in tube is set, the structural cost is high, and the plug-in tube is prone to bending during transportation, causing damage, and to provide a testing apparatus for a multi-channel optical wavelength division multiplexing device.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] A test device for a multi-channel optical wavelength division multiplexing device, including a main body of the test device for the optical wavelength division multiplexing device. One end of the main body of the test device is provided with a plurality of optical conductor connectors. Corresponding guide tubes and connecting rods are provided on the outer sides of the respective optical conductor connectors. Each guide tube and connecting rod are connected to the main body of the test device. Each guide tube surrounds the corresponding optical conductor connector on the outside, and each connecting rod is located on the outside of the corresponding guide tube. One end of each connecting rod away from the main body of the test device is connected with a clamp.

[0009] Furthermore, the connecting rod is detachably connected to the clamp and the main body of the test device.

[0010] Furthermore, a clamp installation groove is provided at the connection between the connecting rod and the clamp. The clamp installation groove is a groove structure that matches the width of the clamp.

[0011] Furthermore, the connecting rod is connected to the main body of the test device through a snap-fastening joint.

[0012] Furthermore, both the guide tube and the connecting rod are perpendicularly connected to one side end face of the main body of the test device.

[0013] Furthermore, one or more corresponding connecting rods are distributed on the outer sides of the respective guide tubes.

[0014] Furthermore, elastic rings that are in interference fit with the optical conductor to be connected are provided inside the respective guide tubes.

[0015] Furthermore, a plurality of heat dissipation holes are provided on the left and right side shells of the main body of the test device.

[0016] Furthermore, the heat dissipation holes on each side shell are distributed in an array.

[0017] Furthermore, the upper and lower side shells of the main body of the test device are both solid plate-like structures.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) In this solution, guide tubes and connecting rods are provided on the outer sides of the optical conductor connectors. The guide tubes surround the corresponding optical conductor connectors on the outside and are used to assist in guiding the optical conductors inserted into the optical conductor connectors. The connecting rods on the outside of the guide tubes are connected with clamps. When installing the optical conductors, they can pass through the clamps and the guide tubes. After accessing the optical conductor connectors, the clamps sleeved on the outside of the optical conductors can support the optical conductors to a certain extent, so as to inhibit the occurrence of bending at the connection between the optical conductors and the optical conductor connectors, making the connection more stable and reliable, reducing the test error caused by the bending of the optical conductors, and improving the test accuracy of the optical wavelength division multiplexing device; due to the provision of the connecting rods and the clamps, the length of the guide tubes can be set shorter and is not easily damaged during transportation;

[0020] When installing the optical conductor for this structure, it only needs to pass through the clamp and the guiding tube and can be fixed by the clamp. When disassembling the optical conductor, only the clamp needs to be loosened. The disassembly and assembly are convenient, and the structure consumes less materials, is easy to manufacture, and has a lower cost.

[0021] (2) During the test process, the test device of the multi-channel optical wavelength division multiplexing device is prone to generating a large amount of heat, which affects the test effect. There are a plurality of heat dissipation holes on the left and right side shells of the main body of the test device of the present invention, and the heat dissipation holes on each side shell are distributed in an array, which can effectively dissipate heat from the test device of the multi-channel optical wavelength division multiplexing device; the upper and lower side shells of the main body of the test device are both solid plate-like structures without through holes, which can prevent dust from entering from the upper and lower sides and affecting the test effect.

[0022] (3) Both ends of the connecting rod of the present invention are respectively detachably connected to the clamp and the main body of the test device. During transportation, the connecting rod and the clamp can be disassembled and placed in advance to avoid collision damage. Description of the Drawings

[0027] To make the purposes, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Usually, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0029] It should be noted that like reference numerals and letters denote like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the inventive product is customarily placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0031] It should be noted that the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality of" means two or more unless otherwise specifically defined.

[0032] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or suspended, but may be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but may be slightly inclined.

[0033] Embodiment 1

[0034] As Figure 1 and Figure 2 shown, this embodiment provides a test device for a multi-channel optical wavelength division multiplexing device, including a test device main body 1 of the optical wavelength division multiplexing device. A plurality of optical conductor connectors 2 are provided at one end of the test device main body 1. Corresponding guide tubes 3 and connecting rods 4 are provided on the outer sides of the respective optical conductor connectors 2. Each of the guide tubes 3 and connecting rods 4 is connected to the test device main body 1. Each of the guide tubes 3 surrounds the corresponding optical conductor connector 2 on the outside, and each of the connecting rods 4 is located outside the corresponding guide tube 3. A clamp 5 is connected to the end of each connecting rod 4 away from the test device main body 1.

[0035] In this solution, a guide tube 3 and a connecting rod 4 are arranged outside the optical conductor connector 2. The guide tube 3 surrounds the corresponding optical conductor connector 2 and is used to assist in guiding the optical conductor inserted into the optical conductor connector 2. A clamp 5 is connected to the connecting rod 4 outside the guide tube 3. When installing the optical conductor, it can pass through the clamp 5 and the guide tube 3. After accessing the optical conductor connector 2, the clamp 5 sleeved on the outside of the optical conductor can support the optical conductor to a certain extent, so as to inhibit the bending at the connection between the optical conductor and the optical conductor connector 2, make the connection more stable and reliable, reduce the test error caused by the bending of the optical conductor, and improve the test accuracy of the wavelength division multiplexing device.

[0036] When installing the optical conductor in this structure, it only needs to pass through the clamp 5 and the guide tube 3 and can be fixed by the clamp 5. When disassembling the optical conductor, only the clamp 5 needs to be loosened. The disassembly and assembly are convenient, and the structure consumes less materials, is easy to manufacture, and has a lower cost.

[0037] Both the guide tube 3 and the connecting rod 4 are vertically connected to one side end face of the test device body 1, so that the optical wire can be vertically inserted into the optical conductor connector 2.

[0038] One or more corresponding connecting rods 4 are distributed outside each guide tube 3, and the optical conductor assembled by the clamp can be fixed at multiple positions. In this embodiment, the number of connecting rods 4 is one and is arranged directly above the guide tube 3.

[0039] To make the entire test device more stable and reliable during transportation, both ends of the connecting rod 4 are respectively detachably connected to the clamp 5 and the test device body 1.

[0040] As Figure 2 shown, the connection method between the connecting rod 4 and the clamp 5 does not require much structural change, and the relative fixation can be maintained by relying on the locking of the clamp 5 itself. Preferably, to further prevent the clamp from moving, a clamp installation groove 401 is provided at the connection between the connecting rod 4 and the clamp 5. The clamp installation groove 401 is a groove structure matching the width of the clamp 5 and is used to limit the forward and backward movement of the clamp 5.

[0041] The detachable connection method between the connecting rod 4 and the test device body 1 can be selected from snap connection, magnetic attraction connection, screw connection, etc. Preferably, the connecting rod 4 is connected to the test device body 1 through a snap-type quick-connect joint, which is convenient for disassembly and assembly.

[0042] As Figure 3 shown, preferably, to further ensure the stability of the optical conductor connection, an elastic ring 301 with an interference fit with the optical conductor to be connected is provided inside each guide tube 3. The elastic ring 301 is made of elastic materials such as rubber and can assist in fixing the optical conductor to prevent bending and wear.

[0043] During the testing process of the test device for multi-channel optical wavelength division multiplexing equipment, a large amount of heat is easily generated, which affects the test effect. Preferably, a plurality of heat dissipation holes 101 are provided on the outer shells on the left and right sides of the test device main body 1, and the heat dissipation holes 101 on each side outer shell are distributed in an array, which can effectively dissipate heat from the test device for multi-channel optical wavelength division multiplexing equipment; the upper and lower outer shells of the test device main body 1 are both solid plate-like structures without through holes to prevent dust from entering from the upper and lower sides and affecting the test effect.

[0044] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in this technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
