Description

Technical Field

[0001] The present invention relates to the field of optical fiber communication technology, and particularly relates to a reflector. Background Art

[0002] With the rapid development of optical fiber communication technology, optical networks have been widely used. As the number of optical network users increases day by day, multiple optical fiber links are intertwined and connected between each node, forming a complex network topology, which brings great challenges to operators for monitoring the status of optical network links.

[0003] Most of the intermediate nodes in optical networks adopt the scheme of passive optical devices, and port management mostly relies on labels for identification and is recorded manually. Problems such as port mapping errors or information loss are likely to occur during data maintenance, and the visibility of the link is low. At the same time, each node in the optical network is interconnected. Once a fiber optic communication signal fails at a certain node, it is very difficult to troubleshoot.

[0004] Currently, the commonly used link detection method in the industry is to use an OTDR (Optical Time-Domain Reflectometer) to detect each link one by one and record manually. This method has a long test time, high cost, and the risk of introducing end face contamination or damage due to contact measurement. Summary of the Invention

Detailed Embodiments

[0021] To enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solution in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0022] The embodiments of this application provide a reflector.

[0023] In one embodiment, referring to Figure 1 , Figure 1 is a schematic structural diagram of an embodiment of the reflector of this application. As Figure 1 shown, the reflector includes: a connection component 1 and a reflection main body component 2.

[0024] Referring to Figure 2 and Figure 3 shown, the reflection main body component 2 includes a support carrier 21, the support carrier 21 is received in the connection component 1, and a reflection member is fixed on the support carrier 21, and a reflection film is plated on the reflection member, and the reflection film is configured to reflect, transmit or block an optical signal of a preset wavelength according to a preset ratio.

[0025] It can be understood that by plating different reflection films on different reflectors, different reflectors can be used for wavelength identification of different ports of each node in the networking solution. Different nodes can be identified according to the distance of the reflected optical signal, and the specific port can be calibrated according to the wavelength of the reflected optical signal. By analyzing the change in the signal intensity of the reflected light, the status of each branch can be monitored.

[0026] In this embodiment, the reflection main body component 2 is a functional component, and a reflection film is plated on its reflection member; the connection component 1 is used to protect the reflection main body component and realize the assembly and disassembly of the reflection main body component and the networking link fulcrum device.

[0027] The specific structure of the reflection member can be reasonably set according to needs. Referring to Figures 1 to 7 shown, in the first embodiment, the reflection member includes a base 22 and a reflection sheet 23.

[0028] Among them, the base 22 is fixed in the receiving cavity of the support carrier 21, and one end of the base 22 extends out of the connection component 1; the reflection sheet 23 is fixed on one end of the base 22 extending out of the connection component 1, and the reflection film is plated on the end of the reflection sheet 23 away from the base 22.

[0029] That is to say, in this embodiment, a base 22 is installed on the support carrier 21, and then a reflector 23 plated with a reflective film is installed on the base 22. Specifically, during implementation, a large glass sheet is directly coated and then cut. This method has cost advantages.

[0030] An embedding groove is provided above the base 22 in this embodiment for the assembly of the reflector 23. A blind hole 221 is provided in the middle, and one end of the blind hole 221 extends to one end of the reflector 23 close to the base 22. The blind hole 221 is provided to increase an optical path length, avoiding the reflected light directly irradiating the base 22 after passing through the reflector 23, thus affecting the reflection of a specific wavelength.

[0031] Preferably, the base 22 is made of an elastic material, so that when docking with the connector, the angle can be finely adjusted through flexible deformation, thus ensuring that the reflective film always tightly adheres to the corresponding optical end face of the connector. In addition, a guiding and positioning boss 222 is provided on the base 22 for guiding and positioning when assembling into the support carrier 21.

[0032] The support carrier 21 in this embodiment has a hollow structure, and an embedding groove 212 is provided above for the assembly with the base 22. The cylindrical structure at the front end serves a connection guiding function to ensure that the reflection main body assembly 2 can be inserted into the adapter. A glue filling groove 213 is provided above the cylindrical structure for glue filling and sealing after the base 22 is assembled, so that the base 22 is fixedly connected to the support carrier 21.

[0033] The connection assembly 1 in this embodiment can provide protection for the reflection main body assembly 2, and at the same time enable the reflection main body assembly 2 to be quickly connected and disconnected from the networking link fulcrum device. Specifically, the connection assembly 1 includes an inner shell 11, an elastic element 12, and an outer shell 13 for connecting the reflection main body assembly 2 with the networking link fulcrum device.

[0034] The elastic element 12 is arranged inside the inner shell 11, and one end of the support carrier 21 is threaded through the elastic element 12 to elastically abut inside the inner shell 11. Thus, by connecting the support carrier 21 and the inner shell 11 through the elastic element 12, an elastic force can be provided for the reflection main body assembly 2, making the reflective film on it tightly adhere to the optical end face of the connector.

[0035] A groove 111 is provided on the inner shell 11. The support carrier 21 is received inside the inner shell 11, and a first boss 211 is also provided on the support carrier 21 for mating and engaging with the groove 111. In addition, a second boss 112 is also provided on the inner shell 11, and the second boss 112 can cooperate with the buckle in the adapter port of the networking link fulcrum device to achieve quick assembly and disengagement. After the reflector is assembled, the reflector 23 is docked with the link fulcrum connector, and the optical signal of the preset wavelength is reflected, transmitted, or blocked according to the preset ratio.

[0036] See Figures 8 to 10 As shown, in the second embodiment, the reflector includes: A ceramic ferrule 24, which is fixed on the support carrier 21. One end of the ceramic ferrule 24 extends out of the connection assembly 1 and is coated with the reflective film at this end, and an optical fiber 241 is also pre-embedded inside the ceramic ferrule 24.

[0037] In this embodiment, the reflection main body assembly mainly includes a support carrier 21 and a ceramic ferrule 24. The ceramic ferrule 24 is fixed to the support carrier 21 by crimping. An optical fiber 241 is pre-embedded inside the ceramic ferrule 24. By coating the reflective film on the optical end face of the ceramic ferrule 24, the reflective film can uniformly cover the end face of the optical fiber, realizing the same function as in the first embodiment.

[0038] It should be noted that, compared with the first embodiment, the solution in this embodiment has a simpler structure and does not require an additional base 22 and a reflector 23 installed on the base 22. However, since coating the ceramic ferrule 24 is more costly than coating the reflector 23, specific selection can be made according to the actual situation.

[0039] In addition, for the structures of the support carrier 21 and the connection assembly 1, reference can be made to the relevant descriptions in the first embodiment. Since there is no base 22 in the second embodiment, the structure of the front end of the support carrier 21 is adaptively adjusted.

[0040] See Figure 11 As shown, in the third embodiment, the reflector includes: A ceramic ferrule 24, which is fixed in the receiving cavity of the support carrier 21. One end of the ceramic ferrule 24 extends out of the connection assembly 1, and the other end is located in the receiving cavity and is spaced apart from the inner wall of the receiving cavity formed in the radial direction.

[0041] A reflector 23, which is fixed on one end of the ceramic ferrule 24 located in the receiving cavity, and the reflective film is coated on the surface of the reflector 23 in contact with the ceramic ferrule 24.

[0042] It should be noted that the ceramic ferrule 24 is spaced apart from the inner wall of the receiving cavity formed in the radial direction. On the one hand, it is to leave space for installing the reflector 23, and on the other hand, it also plays a role similar to the blind hole 221 in the first embodiment, preventing the reflected light from directly irradiating on the support carrier 21 after passing through the reflector 23, thus affecting the reflection of specific wavelengths.

[0043] The structures of the support carrier 21 and the connection assembly 1 are the same as those in the second embodiment, and reference can also be made to the relevant descriptions in the first embodiment.

[0044] It can be understood that, compared with the second embodiment, the solution in this embodiment adds a reflector 23, but the reflective film is adjusted to be plated on the reflector 23. That is, to a certain extent, the number of components is increased, but the cost of coating is reduced. Therefore, in actual production, the above three implementation methods can be selected according to needs.

[0045] In summary, the reflector in this application includes a connection component 1 and a reflection main body component 2. The reflection main body component 2 includes a support carrier 21. The support carrier 21 is received in the connection component 1, and a reflector is fixed on the support carrier 21. A reflective film is plated on the reflector, and the reflective film is configured to reflect, transmit, or block an optical signal of a preset wavelength according to a preset ratio.

[0046] Thus, in a networking solution, different reflectors can be used for wavelength identification of different ports of each node. Different nodes can be identified according to the distance of the reflected optical signal, and the specific port can be calibrated according to the wavelength of the reflected optical signal. The signal intensity change of the reflected light is analyzed, and then the states of each branch can be monitored.
