Description

Technical Field

[0001] This utility model specifically relates to a dedicated testing device for debugging the optical ports of fiber optic switches, belonging to the field of fiber optic communication equipment technology. Background Technology

[0002] In recent years, with the rapid development of applications such as cloud computing, big data, and artificial intelligence, the demand for fiber optic switches has grown rapidly. During the production of fiber optic switches, optical port debugging is a crucial step in ensuring equipment performance. Traditional debugging methods mainly rely on directly inserting small pluggable transceiver modules into the switch's optical ports, or using specialized fixtures to insert multiple sets of small pluggable transceiver modules at once for testing.

[0003] However, due to the massive production volume of fiber optic switches and the fact that each switch has multiple optical ports requiring debugging, frequent plugging and unplugging operations can cause wear and even failure of the gold fingers on small pluggable optical transceiver modules. Because these small optical modules have a compact structure and adopt an integrated design, once the gold fingers are worn, the entire optical module usually needs to be scrapped, resulting in waste and significantly increasing production costs. Utility Model Content

[0004] The purpose of this invention is to provide a dedicated testing device for debugging optical ports of fiber optic switches, which overcomes the problem in the prior art where the gold fingers of small pluggable transceiver modules wear out or even fail due to frequent plugging and unplugging during the debugging of optical ports of fiber optic switches. It also features a simple structure, ease of use, and significantly reduced production costs.

[0005] To achieve the above objectives, the technical solution of this utility model is: a dedicated testing device for debugging the optical ports of fiber optic switches, the innovation of which lies in: including a housing, internal adapter components, a transceiver module, and a replaceable PCB board.

[0006] The casing contains an internal adapter and two light-emitting modules.

[0007] The internal adapter component includes an adapter PCB board and two SFP cage components for receiving and transmitting electrical signals. Both SFP cage components are fixed to the adapter PCB board and electrically connected. Two receiving and transmitting modules are simultaneously inserted into one of the SFP cage components, and the electrical signals output by the two receiving and transmitting modules are transferred to the adapter PCB board through this SFP cage component.

[0008] Two replaceable PCB boards are fixed to the outside of the housing, forming a pluggable structure with the optical port of the fiber optic switch. The two replaceable PCB boards are electrically connected to another SFP cage component, and the SFP cage component transfers the electrical signals on the adapter PCB board to the replaceable PCB boards, thereby transferring the electrical signals of the receiving and transmitting modules to the replaceable PCB boards.

[0009] In the above technical solution, the interior of the housing is provided with a PCB board positioning groove and an SFP cage component limiting component. The PCB board is set in the PCB board positioning groove, and the two SFP cage components arranged side by side on the PCB board are limited by the SFP cage component limiting component.

[0010] In the above technical solution, the housing is provided with a limiting support beam inside, and two receiving and light-emitting modules are arranged in an upper and lower structure inside the housing. One receiving and light-emitting module is arranged side by side with the adapter PCB board, and the end of the receiving and light-emitting module is embedded in the bottom limiting slot of the housing. The other receiving and light-emitting module is arranged on the limiting support beam, and its end is embedded in the top limiting slot of the housing.

[0011] In the above technical solution, the housing includes a housing body and a side plate. The internal adapter and the two light-emitting modules are all located inside the housing body, and the side plate is located on one side of the housing body and is detachably connected to it. The replaceable PCB board is clipped onto the outside of the housing body and is detachably connected to it.

[0012] In the above technical solution, the end of the main body of the casing has two board connection parts arranged vertically and horizontally, and two replaceable PCB boards are detachably connected to the corresponding board connection parts. The replaceable PCB boards have gold fingers that form a pluggable structure with the optical port of the fiber optic switch.

[0013] In the above technical solution, both the main body of the casing and the side panels are made of epoxy resin.

[0014] In the above technical solution, the surface of the replaceable PCB board is provided with a gold plating layer to enhance its wear resistance.

[0015] In the above technical solution, the gold fingers of each of the two light-emitting modules are electrically connected to the corresponding SFP cage component.

[0016] In the above technical solution, both the adapter PCB and the replaceable PCB are covered with signal transfer lines composed of several copper foils. One SFP cage component receives the electrical signal output by the receiving and transmitting module and sends it to the signal transfer line of the adapter PCB. Another SFP cage component transfers the electrical signal from the signal transfer line on the adapter PCB to the signal transfer line of the replaceable PCB.

[0017] The positive effects of this utility model are: after adopting the dedicated testing device for debugging the optical port of a fiber optic switch according to this utility model, since this utility model includes a housing, an internal adapter component, a transceiver module, and a replaceable PCB board, the housing is equipped with an internal adapter component and two transceiver modules.

[0018] The internal adapter component includes an adapter PCB board and two SFP cage components for receiving and transmitting electrical signals. Both SFP cage components are fixed to the adapter PCB board and electrically connected. Two receiving and transmitting modules are simultaneously inserted into one of the SFP cage components, and the electrical signals output by the two receiving and transmitting modules are transferred to the adapter PCB board through this SFP cage component.

[0019] Two replaceable PCB boards are fixed to the outside of the housing, forming a pluggable structure with the optical port of the fiber optic switch. The two replaceable PCB boards are electrically connected to another SFP cage component, and the SFP cage component transfers the electrical signals on the adapter PCB board to the replaceable PCB boards, thereby transferring the electrical signals of the receiving and transmitting modules to the replaceable PCB boards.

[0020] Therefore, in this invention, one SFP cage component connects to the two receiving and transmitting modules, and is responsible for transferring multiple signals from the receiving and transmitting modules to the adapter PCB board. The other SFP cage component connects to the two replaceable PCB boards, and is responsible for transferring multiple electrical signals from the adapter PCB board to the replaceable PCB board. The replaceable PCB board is responsible for receiving and carrying the electrical signals transmitted by the receiving and transmitting modules.

[0021] This invention adopts a modular structure design, dividing it into a non-consumable part and a consumable part. This allows for the transfer of electrical signals from the easily damaged gold finger components of the small pluggable transceiver module to a replaceable PCB board. During debugging, the replaceable PCB board is inserted into the optical port of the switch to complete the debugging process. If debugging fails due to wear of the replaceable PCB board, only the replaceable PCB board needs to be replaced at a low cost, without scrapping the entire optical module. This significantly reduces the wear and maintenance costs of the small pluggable transceiver module during debugging. Simultaneously, the replaceable PCB board maintains the original electrical interface characteristics of the small pluggable transceiver module, and this replacement scheme does not affect the original electrical performance of the small pluggable transceiver module.

[0022] In summary, this invention replaces the existing debugging scheme where the receiving and transmitting modules are directly plugged into the optical port of the fiber optic switch. It transfers the electrical signals to a replaceable and low-cost replaceable PCB board, which is then plugged into the optical port of the fiber optic switch for debugging. This not only simplifies the structure and makes it easy to use, but also greatly reduces production costs. It also overcomes the problem in the existing technology where the gold fingers of the small pluggable receiving and transmitting modules wear out or even fail due to frequent plugging and unplugging during the debugging of the optical port of the fiber optic switch.

[0025] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but it is not limited thereto.

[0026] like Figure 1 , 2 As shown, a dedicated testing device for debugging the optical ports of a fiber optic switch includes a housing 1, an internal adapter 2, a transceiver module 3, and a replaceable PCB board 4.

[0027] The housing 1 is equipped with an internal adapter 2 and two light-emitting modules 3.

[0028] The internal adapter component 2 includes an adapter PCB board 21 and two SFP cage components 22 for receiving and transmitting electrical signals. Both SFP cage components 22 are fixed to the adapter PCB board 21 and form an electrical connection. Two receiving and transmitting modules 3 are simultaneously inserted into one of the SFP cage components 22, and the electrical signals output by the two receiving and transmitting modules 3 are transmitted to the adapter PCB board 21 through this SFP cage component 22.

[0029] Two replaceable PCB boards 4 are fixed to the outside of the housing 1, forming a pluggable structure with the optical port of the fiber optic switch. The two replaceable PCB boards 4 are electrically connected to another SFP cage component 22. The SFP cage component 22 transfers the electrical signals on the adapter PCB board 21 to the replaceable PCB boards 4, thereby transferring the electrical signals of the receiving and transmitting module 3 to the replaceable PCB boards 4.

[0030] Furthermore, such as Figure 1 , 2As shown, in order to enable rapid positioning and assembly of internal adapter components and to limit the movement of SFP cage components, effectively preventing damage to components caused by shaking inside the housing, the housing 1 is provided with an adapter PCB board positioning slot and an SFP cage component limiting member 11. The adapter PCB board 21 is disposed in the adapter PCB board positioning slot, and two SFP cage components 22 arranged side by side on the adapter PCB board 21 are limited by the SFP cage component limiting member 11. Specifically, the housing is provided with multiple SFP cage component limiting members, which can limit the top and sides of the SFP cage components.

[0031] Furthermore, such as Figure 1 , 2 As shown, in order to enable rapid assembly and positioning of the receiving and emitting modules, a limiting support beam 12 is provided inside the housing 1. Two receiving and emitting modules 3 are arranged in an upper and lower structure inside the housing 1. One receiving and emitting module 3 is arranged side by side with the adapter PCB board 21, and its end is embedded in the bottom limiting slot 132 of the housing 1. The other receiving and emitting module 3 is located on the limiting support beam 12, and its end is embedded in the top limiting slot 133 of the housing 1. The limiting support beam 12 not only supports one of the receiving and emitting modules, but also limits the side of an SFP cage component. The end of the limiting support beam 12 is also provided with a limiting groove to limit the end of the receiving and emitting module 3.

[0032] Furthermore, such as Figure 1 As shown, in order to achieve an overall modular structure design while making the structure compact and small, the housing 1 includes a housing body 13 and a side plate 14. The internal adapter 2 and the two light-emitting and receiving modules 3 are all located inside the housing body 13, and the side plate 14 is located on one side of the housing body 13 and is detachably connected to it. The replaceable PCB board 4 is located outside the housing body 13 and is detachably connected to it.

[0033] Furthermore, such as Figure 1 As shown, in order to quickly locate and assemble replaceable PCB boards and enable a quick plug-in structure with the optical port of the switch, the end of the main body 13 of the housing has two board connection parts 131 arranged vertically and horizontally. The two replaceable PCB boards 4 are detachably connected to the corresponding board connection parts 131. The replaceable PCB boards 4 have gold fingers 41 that form a pluggable structure with the optical port of the fiber optic switch.

[0034] Furthermore, in order to ensure the mechanical and electrical properties (insulation) of the overall structure of the housing, both the main body 13 and the side plate 14 of the housing are made of epoxy resin.

[0035] Furthermore, to increase wear resistance and service life, the surface of the replaceable PCB board 4 is provided with a gold-plated layer to enhance its wear resistance.

[0036] Furthermore, in order to achieve electrical connection between the light-emitting and receiving modules and the SFP cage components, the gold fingers of each of the two light-emitting and receiving modules 3 are electrically connected to the corresponding SFP cage components 22.

[0037] Furthermore, both the adapter PCB 21 and the replaceable PCB 4 are covered with signal transfer lines composed of several copper foils. One SFP cage component 22 receives the electrical signal output by the receiving and transmitting module 3 and sends it to the signal transfer line of the adapter PCB 21. Another SFP cage component 22 transfers the electrical signal from the signal transfer line on the adapter PCB 21 to the signal transfer line of the replaceable PCB 4.

[0038] Furthermore, the thickness of both the adapter PCB board 21 and the replaceable PCB board 4 described in this utility model is 1mm, in order to ensure the compactness and structural stability of the device.

[0039] In the assembly process of this utility model, firstly, two SFP cage components 22 are fixed to the adapter PCB board 21 to form the internal adapter component 2; then, the internal adapter component 2 and two small pluggable light-emitting modules 3 are placed together inside the main body 13 of the housing, and the side plate 14 is connected and fixed to the main body 13 of the housing with screws to form the non-consumable part of the device. Finally, two replaceable PCB boards 4 are inserted into the corresponding SFP cage components 22 and detachably connected to the board connection part 131 of the main body 13 of the housing with screws, thereby forming the entire device.

[0040] In this invention, one SFP cage component 22 connects to the two receiving and transmitting modules 3, and is responsible for transferring multiple signals from the receiving and transmitting modules 3 to the adapter PCB board 21. The other SFP cage component 22 connects to the two replaceable PCB boards 4, and is responsible for transferring multiple electrical signals from the adapter PCB board 21 to the replaceable PCB board 4. The replaceable PCB board 4 is responsible for receiving and carrying the electrical signals transmitted by the receiving and transmitting modules.

[0041] This invention adopts a modular structure design, dividing it into a non-consumable part and a consumable part. This allows for the transfer of electrical signals from the easily damaged gold finger components of the small pluggable transceiver module to a replaceable PCB board. During debugging, the replaceable PCB board is inserted into the optical port of the switch to complete the debugging process. If debugging fails due to wear of the replaceable PCB board, only the replaceable PCB board needs to be replaced at a low cost, without scrapping the entire optical module. This significantly reduces the wear and maintenance costs of the small pluggable transceiver module during debugging. Simultaneously, the replaceable PCB board maintains the original electrical interface characteristics of the small pluggable transceiver module, and this replacement scheme does not affect the original electrical performance of the small pluggable transceiver module.

[0042] In summary, this utility model is not only simple in structure and easy to use, but also greatly reduces production costs and overcomes the problem in the prior art where the gold fingers of small pluggable transceiver modules wear out or even fail due to frequent plugging and unplugging during the debugging of optical ports of fiber optic switches.

[0043] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
