Description

Technical Field

[0001] The present application relates to the technical field of optical fiber distribution frames, and in particular to an optical fiber distribution frame. Background Art

[0002] With the rapid development of communication technology, fiber optic distribution frames are gradually used in various communication scenarios, and the functions of fiber optic distribution frames are becoming more and more important.

[0003] In the related art, the optical fiber ports in the optical fiber distribution frame are connected and switched through optical fibers and patch cords for business. Since the length of the patch cords is uncontrollable, generally speaking, the length of the patch cords is fixed and is generally greater than the distance between the ports. Therefore, the patch cords will be cross-entangled when the ports are connected. At the same time, the redundant patch cords can only be coiled in the optical distribution frame. As the number of patch cords increases, the patch cords in the optical fiber distribution frame become messy and coiled, making it impossible to replace or vacate the patch cords, which brings inconvenience to operation and is not aesthetically pleasing. Summary of the invention

[0004] The present application provides a fiber optic distribution frame, which solves the problems of cluttered, coiled and piled-up patch cords in the fiber optic distribution frame, realizes the automatic recovery of redundant length of patch cords, is conducive to keeping the patch cords in the fiber optic distribution frame neat and beautiful, and is convenient for connection, replacement and withdrawal of patch cords, making operation and maintenance more convenient.

[0005] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, an embodiment of the present application provides an optical fiber distribution frame, comprising:

[0007] A box body, wherein an installation space is formed in the box body;

[0008] The optical fiber distribution module is fixed in the installation space. The optical fiber distribution module has multiple optical fiber interfaces, and each optical fiber interface is connected to an optical fiber;

[0009] A fiber jumper storage module, the fiber jumper storage module is fixed in the installation space, the fiber jumper storage module includes a plurality of fiber jumper storage units, each group of fiber jumper storage units corresponds to a fiber jumper, and part of the fiber jumper is arranged in the fiber jumper storage unit, each fiber jumper has a first connector and a second connector, and the fiber jumper is suitable for being pulled out from the fiber jumper storage unit through the first connector and the second connector, respectively, so that the first connector and the second connector are respectively connected to the corresponding optical fiber interface;

[0010] The patch cord storage unit is further adapted to retract a portion of the patch cords pulled out through the first connector and the second connector.

[0011] The fiber optic distribution frame proposed in the embodiment of the present application, when it is necessary to connect the jump fibers in the jump fiber storage module and the optical fibers in the fiber distribution module, determines two optical fiber interfaces to be connected and the corresponding jump fiber storage units, and pulls the jump fibers in the jump fiber storage unit out of the jump fiber storage unit through the first connector and the second connector respectively, so that the first connector and the second connector are respectively connected to the corresponding optical fiber interfaces, thereby realizing the communication connection of the two optical fiber interfaces to be connected; when the first connector and the second connector are connected to the corresponding optical fiber interfaces, the jump fiber storage unit can retract part of the jump fibers pulled out through the first connector and the second connector, so that the redundant length of the jump fibers can be automatically recovered, and the backlog of the jump fibers in the optical fiber distribution frame can be reduced, which is conducive to keeping the jump fibers in the optical fiber distribution frame neat and beautiful, and is convenient for the connection, replacement, and withdrawal of the jump fibers, and the operation and maintenance are also relatively convenient.

[0012] Optionally, the fiber jumper storage unit comprises: a shell and a storage tray, the storage tray is arranged in the shell, and a part of the fiber jumper tray is arranged on the storage tray.

[0013] Thus, the fiber jumpers can be stored in a spiral on the storage tray, which is beneficial to saving storage space.

[0014] Optionally, the fiber jumper storage unit further comprises: a coil spring, which is fixed in the shell and is suitable for providing power for retracting the fiber jumpers on the storage tray.

[0015] Therefore, not only the redundant length of the jumper fiber is automatically recovered and the winding backlog of the jumper fiber in the optical fiber distribution frame is reduced, but also the driving process is simple, reliable and low-cost.

[0016] Optionally, the jumper fiber is a single-mode optical fiber.

[0017] Therefore, under radius bending conditions, the jumper fiber can effectively suppress bending loss and has excellent anti-bending fatigue performance. At the same time, when the redundant length of the jumper fiber is automatically stored, the good high anti-fatigue parameters are beneficial to improving the service life under a small bending radius.

[0018] Optionally, the optical fiber distribution frame further includes: a wire clip, which is fixed in the installation space and is used to fix the portion of the jumper fiber pulled out from the jumper fiber storage unit.

[0019] Therefore, on the one hand, the redundant patch cords can be made neater and more beautiful, and at the same time, the patch cords can be prevented from swinging back and forth and causing mutual entanglement between different patch cords. On the other hand, it is easy to find and replace the patch cords, thereby improving operation and maintenance efficiency.

[0020] Optionally, there are multiple wire clips, and the multiple wire clips are arranged at intervals along the height direction of the optical fiber distribution frame.

[0021] Therefore, by setting up multiple wire clips, more fixed installation points can be provided for the pulled-out jumper fibers, thereby improving the routing aesthetics of the jumper fibers, avoiding the back-and-forth movement of the jumper fibers connected between the two terminals, and further reducing the risk of cross-entanglement between different jumper fibers.

[0022] Optionally, the cable clip has a first clamping portion and a second clamping portion that are arranged opposite to each other, and a portion of the jumper pulled out of the jumper storage unit is clamped between the first clamping portion and the second clamping portion.

[0023] Therefore, the installation and disassembly of the jumper on the cable clip is convenient, the structure is simple and the cost is low.

[0024] Optionally, the fiber optic distribution frame further includes: a sensing module, which is fixed in the installation space, and the sensing module is communicatively connected with the fiber optic distribution module and the fiber jumper storage module.

[0025] Thus, real-time monitoring of the usage of the ports of the optical fiber distribution module and the jumper storage module is achieved.

[0026] Optionally, the sensing module has a display, and the display is used to display the optical fiber connection information.

[0027] In this way, the usage of the fiber jumper storage unit and the optical fiber interface can be clearly displayed, making it easier to connect, replace, and vacate the fiber jumpers.

[0028] Optionally, the core of the optical fiber in the optical fiber distribution module is the same as the core of the jump fiber in the jump fiber storage module.

[0029] This helps reduce the insertion loss of jumpers in optical fiber distribution frames and improve the insertion loss standard of fiber core links. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0041] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0042] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements.

[0044] The term "multiple" as used in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple sheets" refers to more than two sheets (including two sheets).

[0045] It should be noted that with the rapid development of communication technology, fiber optic distribution frames are gradually used in various communication scenarios, and the functions of fiber optic distribution frames are becoming more and more valued.

[0046] In the related art, the optical fiber ports in the optical fiber distribution frame are connected and switched through optical fibers and patch cords for business. Since the length of the patch cords is uncontrollable, generally speaking, the length of the patch cords is fixed and is generally greater than the distance between the ports. Therefore, the patch cords will be cross-entangled when the ports are connected. At the same time, the redundant patch cords can only be coiled in the optical distribution frame. As the number of patch cords increases, the patch cords in the optical fiber distribution frame become messy and coiled, making it impossible to replace or vacate the patch cords, which brings inconvenience to operation and is not aesthetically pleasing.

[0047] Based on this, the present application proposes a fiber optic distribution frame 100. When it is necessary to connect the jumper 4 in the jumper storage module 3 and the optical fiber in the fiber distribution module 2, two optical fiber interfaces 21 to be connected and the corresponding jumper storage units 31 are determined, and the jumper 4 in the jumper storage unit 31 is pulled out from the jumper storage unit 31 through the first connector 41 and the second connector 42 respectively, so that the first connector 41 and the second connector 42 are respectively connected to the corresponding optical fiber interface 21, thereby realizing the communication connection of the two optical fiber interfaces 21 to be connected. When the first connector 41 and the second connector 42 are connected to the corresponding optical fiber interface 21, the jumper storage unit 31 can retract part of the jumper 4 pulled out through the first connector 41 and the second connector 42. In this way, the redundant length of the jumper 4 can be automatically recovered, and the winding backlog of the jumper 4 in the optical fiber distribution frame 100 can be reduced, which is conducive to keeping the jumper 4 in the optical fiber distribution frame 100 neat and beautiful, and it is convenient to connect, replace, and vacate the jumper 4, and the operation and maintenance are also more convenient.

[0048] The optical fiber distribution frame 100 proposed in the embodiment of the present application is described below with reference to the accompanying drawings.

[0049] like Figure 1 As shown, the optical fiber distribution frame 100 according to the first embodiment of the present application includes: a box body 1, an optical fiber distribution module 2 and a jumper storage module 3.

[0050] An installation space 11 is formed in the box 1. Optionally, the box 1 includes a box body 1 and an openable door. The box body 1 and the door together define the installation space 11. The optical fiber distribution module 2 is fixedly arranged in the installation space 11. The fixed installation method includes but is not limited to bolt connection, clamping, etc. Further, the optical fiber distribution module 2 has a plurality of optical fiber interfaces 21, such as Figure 1 As shown, the fiber distribution module 2 includes a plurality of fiber optic interfaces 21 distributed in an array. To facilitate identification of the fiber optic interfaces 21, each fiber optic interface 21 is numbered, and each fiber optic interface 21 is connected to an optical fiber. It can be understood that each optical fiber can be connected to different devices or routers, and the specific settings are based on actual needs, and no specific restrictions are made here.

[0051] Furthermore, the patch cord storage module 3 is also fixedly arranged in the installation space 11. Figure 1 As shown, the fiber jumper storage module 3 can be installed above the optical fiber distribution module 2, or below the optical fiber distribution module 2, or on the side of the optical fiber distribution module 2, wherein the fiber jumper storage module 3 includes a plurality of fiber jumper storage units 31. For example, Figure 1 As shown, the fiber jumper storage module 3 includes two rows of fiber jumper storage units 31, each row has 8 groups of fiber jumper storage units 31, that is, the fiber jumper storage module 3 includes a total of 16 groups of fiber jumper storage units 31, each group of fiber jumper storage units 31 is correspondingly provided with a fiber jumper 4, and part of the fiber jumper 4 is arranged in the fiber jumper storage unit 31, each fiber jumper 4 has a first connector 41 and a second connector 42, and the fiber jumper 4 is suitable for being pulled out from the fiber jumper storage unit 31 through the first connector 41 and the second connector 42, respectively, so that the first connector 41 and the second connector 42 are respectively connected to the corresponding optical fiber interface 21. Further, as a specific example, when it is necessary to connect the fiber jumper 4 in the fiber jumper storage module 3 with the optical fiber in the optical fiber distribution module 2, as shown in FIG. Figure 1 As shown, part of the jumper 4 is pulled out from one jumper storage unit 31 through the first connector 41 (A1) and the second connector 42 (B1), so that the first connector 41 (A1) and the second connector 42 (B1) are respectively connected to the optical fiber interface 21 (a1) and the optical fiber interface 21 (g2) in the optical fiber distribution module 2. Further, part of the jumper 4 is pulled out from another jumper storage unit 31 through the first connector 41 (C1) and the second connector 42 (D1), so that the first connector 41 (C1) and the second connector 42 (D1) are respectively connected to the optical fiber interface 21 (c2) and the optical fiber interface 21 (e3) in the optical fiber distribution module 2. With such a configuration, the connection between the optical fiber and the jumper 4 is realized, and the jumper connection and conduction of the link are completed without too many cables, and the deployment work is simple and convenient.

[0052] Understandably, reference Figure 1As shown, the first connector 41 and the second connector 42 are both disposed outside the patch cord storage unit 31 , so that the patch cord 4 can be easily pulled out of the patch cord storage unit 31 through the first connector 41 and the second connector 42 .

[0053] Further, after the first connector 41 and the second connector 42 are connected to the corresponding optical fiber interface 21, the fiber jumper storage unit 31 is also suitable for retrieving part of the fiber jumpers 4 pulled out through the first connector 41 and the second connector 42. That is, after part of the fiber jumpers 4 are pulled out through the first connector 41 or the second connector 42 and connected to the corresponding optical fiber interface 21, the length of the pulled fiber jumpers 4 may be too long, resulting in redundant length of the fiber jumpers 4. At this time, the fiber jumper storage unit 31 can retrieve part of the fiber jumpers 4 pulled out through the first connector 41 and the second connector 42, thereby reducing the redundant length of the fiber jumpers 4 as much as possible and avoiding the situation where the fiber jumpers 4 are piled up. The length retrieved by the fiber jumper storage unit 31 is controllable and adjustable. Preferably, it is optimal to straighten the fiber jumpers 4 after the redundant length of the fiber jumpers 4 is retrieved by the fiber jumper storage unit 31. With such an arrangement, the redundant length of the jumper fiber 4 can be automatically recovered through the jumper fiber storage unit 31, reducing the winding backlog of the jumper fiber 4 in the optical fiber distribution frame 100, which is beneficial to keeping the jumper fiber 4 in the optical fiber distribution frame 100 neat and beautiful, and is convenient for the connection, replacement, and withdrawal of the jumper fiber 4, and operation and maintenance are also relatively convenient.

[0054] To summarize, the fiber optic distribution frame 100 proposed in the embodiment of the present application, when it is necessary to connect the jumper 4 in the jumper storage module 3 and the optical fiber in the optical fiber distribution module 2, determines two optical fiber interfaces 21 to be connected and the corresponding jumper storage units 31, and pulls the jumper 4 in the jumper storage unit 31 out of the jumper storage unit 31 through the first connector 41 and the second connector 42 respectively, so that the first connector 41 and the second connector 42 are respectively connected to the corresponding optical fiber interfaces 21, thereby realizing the communication connection of the two optical fiber interfaces 21 to be connected. When the first connector 41 and the second connector 42 are connected to the corresponding optical fiber interfaces 21, the jumper storage unit 31 can retract part of the jumper 4 pulled out through the first connector 41 and the second connector 42. In this way, the redundant length of the jumper 4 can be automatically recovered, and the winding backlog of the jumper 4 in the optical fiber distribution frame 100 can be reduced, which is conducive to keeping the jumper 4 in the optical fiber distribution frame 100 neat and beautiful, and is convenient for the connection, replacement, and withdrawal of the jumper 4, and the operation and maintenance are also relatively convenient.

[0055] In some embodiments of the present application, the patch cord storage unit 31 includes: a shell and a storage tray, the storage tray is disposed in the shell, and a portion of the patch cord 4 is disposed on the storage tray.

[0056] Specifically, the core component of the jumper storage unit 31 is a storage tray arranged in the shell, and the storage tray is used to store part of the jumpers 4 located in the shell. Such a configuration enables the spiral storage of the jumpers 4 on the storage tray, which is conducive to saving storage space.

[0057] Furthermore, as a specific example, the fiber jumper storage unit 31 can realize the guiding and redirection of the double-ended lead-out of the same fiber jumper 4, that is, the fiber jumper 4 can be pulled out from the fiber jumper storage unit 31 at the same time through the first connector 41 and the second connector 42. Specifically, the storage disk has an outer ring winding groove and a middle wire groove, the middle part of the middle wire groove has a meandering channel, the inner ring of the meandering channel is provided with a reversing wheel for guiding the bending of the fiber jumper 4, the reversing wheel is rotatably arranged on the center column of the storage disk, and the meandering channel has a junction area connecting the reversing wheel and the outer ring winding groove. With such an arrangement, the guiding and redirection of the double-ended lead-out of the same fiber jumper 4 is realized through the coordinated use of the middle wire groove, the reversing wheel and the outer ring winding groove. It should be noted that this technical solution is a prior art and will not be described in detail here.

[0058] In some embodiments of the present application, the fiber jumper storage unit 31 further includes: a coil spring, which is fixed in the housing, and is suitable for providing power for the retraction of the fiber jumper 4 on the storage tray. That is to say, the coil spring can convert its stored mechanical energy into kinetic energy for driving the fiber jumper 4 to be retracted. As a specific example, one end of the coil spring is fixedly connected to the housing, and the other end is fixedly connected to the reversing wheel of the storage tray. Assuming that when the fiber jumper 4 is pulled out of the fiber jumper storage unit 31 through the first connector 41 or the second connector 42, the coil spring rotates forward and accumulates mechanical energy. When part of the fiber jumper 4 needs to be recovered to the fiber jumper storage unit 31, the coil spring rotates in the opposite direction and releases mechanical energy to drive the fiber jumper 4 to be retracted. Such a setting not only realizes the automatic recovery of the redundant length of the fiber jumper 4, but also reduces the winding backlog of the fiber jumper 4 in the optical fiber distribution frame 100, and the driving process is simple and reliable, and the cost is low.

[0059] In some embodiments of the present application, the fiber jumper storage unit 31 further includes: a motor, which is fixed in the housing, and the motor is suitable for providing power for the retraction of the fiber jumpers 4 on the storage tray. That is to say, the output shaft of the motor can provide kinetic energy for the retraction of the fiber jumpers 4. As a specific example, the motor is fixedly installed in the housing, and the output shaft of the motor is fixedly connected to the reversing wheel of the storage tray. Assuming that when the fiber jumpers 4 are pulled out of the fiber jumper storage unit 31 through the first connector 41 or the second connector 42, the output shaft of the motor rotates forward under the action of the reversing wheel. When it is necessary to recycle part of the fiber jumpers 4 to the fiber jumper storage unit 31, the output shaft of the motor is controlled to rotate in the opposite direction to drive the fiber jumpers 4 to be retracted. Such a setting not only realizes the automatic recovery of the redundant length of the fiber jumpers 4, reduces the winding backlog of the fiber jumpers 4 in the optical fiber distribution frame 100, but also the drive control is more precise, and the precise recovery of the redundant fiber jumpers 4 can be realized.

[0060] In some embodiments of the present application, the jumper 4 is a single-mode optical fiber. That is, a bend-insensitive single-mode optical fiber can be selected when the jumper 4 is selected. In this way, under the condition of radius bending, the jumper 4 can well suppress the bending loss and has excellent anti-bending fatigue performance. At the same time, when the redundant length of the jumper 4 is automatically stored, the good high anti-fatigue parameter is conducive to improving the service life under a small bending radius.

[0061] In some embodiments of the present application, Figure 1 As shown, the optical fiber distribution frame 100 further includes: a wire clamp 5 , which is fixed in the installation space 11 and is used to fix a portion of the jumper fiber 4 pulled out from the jumper fiber storage unit 31 .

[0062] Specifically, when the first connector 41 and the second connector 42 are connected to the corresponding optical fiber interface 21, and the fiber jumper storage unit 31 retracts part of the fiber jumpers 4 pulled out through the first connector 41 and the second connector 42, some redundant fiber jumpers 4 can be fixed on the wire clip 5. Such a configuration can, on the one hand, make the redundant fiber jumpers 4 more tidy and beautiful, and at the same time, prevent the fiber jumpers 4 from shaking back and forth and causing mutual entanglement between different fiber jumpers 4. On the other hand, it is convenient to find and replace the fiber jumpers 4, thereby improving the operation and maintenance efficiency.

[0063] In some embodiments of the present application, Figure 1 As shown, there are multiple clamping buckles 5, and the multiple clamping buckles 5 are arranged at intervals along the height direction of the optical fiber distribution frame 100. That is to say, multiple clamping buckles 5 can be arranged at intervals along the height direction of the optical fiber distribution frame 100. For example, the number of clamping buckles 5 can be 2, 3, 4, 5, 6, and 7, which are set according to actual needs and are not specifically limited here. By setting multiple clamping buckles 5, more fixed installation points can be provided for the pulled jumper 4, thereby improving the routing aesthetics of the jumper 4, avoiding the jumper 4 connected between the two terminals from moving back and forth, and further reducing the risk of cross-entanglement between different jumpers 4.

[0064] In some embodiments of the present application, the wire clip 5 has a first clamping portion and a second clamping portion that are arranged opposite to each other, and a portion of the jumper fiber 4 pulled out from the jumper fiber storage unit 31 is clamped between the first clamping portion and the second clamping portion.

[0065] Specifically, the first clamping part and the second clamping part relatively arranged on the wire buckle 5 are both constructed as elastic parts, and a certain gap can be provided between the first clamping part and the second clamping part. It can be understood that the gap between the first clamping part and the second clamping part needs to be smaller than the diameter of the jump fiber 4. When the jump fiber 4 is assembled with the wire buckle 5, the jump fiber 4 is directly clamped between the first clamping part and the second clamping part, and the interaction force between the first clamping part and the second clamping part on the jump fiber 4 is used to fix the jump fiber 4. When the jump fiber 4 needs to be removed from the wire buckle 5, the jump fiber 4 can be directly pulled out from between the first clamping part and the second clamping part. With this arrangement, the installation and disassembly of the jump fiber 4 on the wire buckle 5 is relatively convenient, the structure is simple, and the cost is low.

[0066] In some embodiments of the present application, Figure 1 As shown, the optical fiber distribution frame 100 further includes: a sensing module, which is fixedly arranged in the installation space 11 , and is communicatively connected with the optical fiber distribution module 2 and the jumper fiber storage module 3 .

[0067] Specifically, the perception module is communicatively connected with the port sensor of the optical fiber distribution module 2 and the port sensor of the fiber jumper storage module 3, so that the perception module can obtain the connection information of the optical fiber connector in the optical fiber distribution module 2 and the usage status of each fiber jumper storage unit 31 in the fiber jumper storage module 3, thereby realizing real-time monitoring of the port usage of the optical fiber distribution module 2 and the fiber jumper storage module 3.

[0068] In some embodiments of the present application, Figure 1 As shown, the sensing module also has a display 6, which is used to display the optical fiber connection information. It can be understood that the displayed optical fiber connection information includes the connection information of the optical fiber connector and the usage of the jumper storage unit 31.

[0069] As a specific example, continuing with Figure 1 As shown in the figure, the jumper 4 with the first connector 41 (A1) and the second connector 42 (B1) is connected to the optical fiber interface 21 (a1) and the optical fiber interface 21 (g2) in the optical fiber distribution module 2. Furthermore, the jumper 4 with the first connector 41 (C1) and the second connector 42 (D1) is connected to the optical fiber interface 21 (c2) and the optical fiber interface 21 (e3) in the optical fiber distribution module 2. The sensing module obtains the optical fiber connection information and then displays it on the display screen. For example, the display screen shows: A1 is connected to a1, B1 is connected to g2, C1 is connected to c2, and D1 is connected to e3. With this arrangement, the use of the jumper storage unit 31 and the optical fiber interface 21 can be clearly displayed, which is more convenient for the connection, replacement, and withdrawal of the jumper 4.

[0070] In some embodiments of the present application, the optical fiber distribution frame 100 further includes: a temperature sensor, which is fixed in the installation space 11 and is also communicatively connected to the sensing module. The display 6 is used to display temperature information.

[0071] Specifically, the interior of the box 1 also has a temperature sensor, which is used to obtain the temperature inside the box 1 in real time, and the temperature sensor is also communicated with the sensing module. The display 6 is used to display temperature information. In this way, it is convenient to obtain the temperature conditions inside the box 1. When the temperature is too high, it can be cooled in time to ensure the normal operation of the optical fiber distribution frame 100.

[0072] In some embodiments of the present application, the box 1 is further provided with a heat dissipation hole connected to the installation space 11. That is to say, in order to ensure the heat dissipation in the box 1 and enable the normal operation of each module of the optical fiber distribution frame 100, a heat dissipation hole can be opened on the box 1. It can be understood that the heat dissipation hole is connected to the installation space 11, so as to ensure that the heat in the installation space 11 can be dissipated from the heat dissipation hole in time. It should be noted that the position of the heat dissipation hole can be located at the top of the box 1, or at the bottom, or at the side wall, and it is specifically set according to the actual situation. The number of heat dissipation holes can also be set according to actual needs, and examples are not given here one by one.

[0073] In some embodiments of the present application, the core of the optical fiber in the optical fiber distribution module 2 is the same as the core of the jump fiber 4 in the jump fiber storage module 3 .

[0074] It should be noted that the cores of the optical fibers in the traditional optical fiber distribution module 2 and the jumper fibers 4 in the jumper fiber storage module 3 are from different manufacturers and different batches, and their optical fiber characteristics are different due to the fiber-making process and grade standards, resulting in excessive insertion loss of the port jumper, which in turn causes the optical path and long-distance optical path attenuation performance of the multi-section optical cable to exceed the standard, and even cannot be opened. In addition, since the optical fiber distribution frame 100 is fusion-spliced ​​and separated, the jumper fiber 4 is a later operation configuration, and its core cannot be customized with the core of the optical fiber distribution module 2 from the same manufacturer and the same batch, resulting in large port insertion loss.

[0075] Based on this, the present application integrates the core of the optical fiber in the optical fiber distribution module 2 and the jumper fiber 4 in the jumper fiber receiving module 3 using the core of the same manufacturer and the same batch, and pre-matches the eccentricity and eccentricity angle of the fiber fusion tray tail fiber ceramic ferrule in the optical fiber distribution module 2 and the jumper fiber 4 connector ceramic ferrule in the jumper fiber receiving module 3, thereby reducing the insertion loss of the jumper in the optical fiber distribution frame 100, which is beneficial to improving the insertion loss standard of the fiber core link.

[0076] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.
