Description

Technical Field

[0001] The utility model relates to the technical field of communications, in particular to a fiber splitting box. Background Art

[0002] Fiber splitter boxes play an important role in optical fiber communication systems. They can connect optical fibers to devices and achieve terminal access to optical fibers.

[0003] In the related art, both ends of the optical fiber are connected with connectors, which include a shell, a ceramic tube and a tail handle. The tail handle is connected to the ceramic tube, and the shell is connected to the tail handle and is sleeved on the outside of the ceramic tube to protect the ceramic tube.

[0004] However, the structure of the above-mentioned optical fiber connector is relatively complex, resulting in a larger volume of the optical fiber connector. When more optical fibers are connected in the fiber splitter box, in order to meet the optical fiber connection requirements, the volume of the fiber splitter box also needs to be set larger, which will cause the fiber splitter box to occupy a larger space, thereby affecting the integration of the fiber splitter box. Utility Model Content

[0005] The present application provides a fiber splitter box, which is used to improve the integration of the fiber splitter box.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] A fiber splitter box includes a box body, a splitter box, and a plurality of optical fibers. The splitter box is connected to the box body, and a plurality of connection ports are provided on the splitter box. The plurality of optical fibers correspond to the plurality of connection ports one by one. The optical fiber includes a body and a connector. The connector is connected to the end of the body and can be plugged into or removed from the corresponding connection port.

[0008] The connector includes a tail handle and a ceramic tube. The tail handle forms a fixed channel, and the end of the body is located in the fixed channel and connected to the tail handle. The tail handle can produce elastic deformation along the extension direction of the fixed channel so that the tail handle can switch between a compressed state and a natural state. When the connector is plugged into the corresponding connection port, the tail handle is in a compressed state, and when the connector is withdrawn from the corresponding connection port, the tail handle is in a natural state. The ceramic tube is located in the fixed channel, and the end of the body extends into the ceramic tube and is connected to the ceramic tube. When the tail handle is in a compressed state, the ceramic tube extends to a side of the fixed channel close to the spectrometer box, and the end of the body is electrically connected to the corresponding connection port. When the tail handle is in a natural state, the ceramic tube extends into the fixed channel, and the end of the body is separated from the corresponding connection port.

[0009] Through the above arrangement, when the connector is withdrawn from the corresponding connection port, the ceramic tube is located in the fixed channel, and the tail handle can provide protection for the ends of the ceramic tube and the body, reducing the possibility of damage to the ceramic tube and the body. When the connector needs to be connected to the connection port, the tail handle can be compressed to allow the ceramic tube to extend out of the fixed channel and be electrically connected to the corresponding connection port to achieve signal transmission between the optical fiber and the splitter box.

[0010] By setting the tail handle, while ensuring that the connector can be normally connected to the connection port, the tail handle can also protect the ceramic tube and the main body exiting the connection port. In this way, there is no need to set up a shell to protect the ceramic tube, so the ceramic tube and the main body can be protected. This can simplify the structure of the connector, reduce the volume of the connector, and thus reduce the space occupied by the connector in the box. This can save space in the box to improve the integration of the fiber distribution box.

[0011] Furthermore, the tail handle includes a first sub-segment, a second sub-segment and an elastic member. The first sub-segment is connected to the body. When the connector is plugged into the corresponding connection port, the second sub-segment is located on the side of the first sub-segment close to the spectrometer box. The elastic member is located between the first sub-segment and the second sub-segment, and is connected to both the first sub-segment and the second sub-segment. When the connector is plugged into the corresponding connection port, the second sub-segment abuts against the spectrometer box, and the first sub-segment and the second sub-segment squeeze the elastic member.

[0012] Through the above-mentioned arrangement, in the process of connecting the connector and the first connecting port, the connector and the first connecting port can be aligned first, and the second sub-segment can be abutted against the spectrometer box, and then the first sub-segment can be pushed to move toward the spectrometer box. During the movement of the first sub-segment, the elastic member will be gradually compressed, and the distance between the first sub-segment and the second sub-segment will be gradually shortened.

[0013] Since the ceramic tube is connected to the main body, and the main body is connected to the first sub-segment, during the movement of the first sub-segment, the ceramic tube will move with the first sub-segment toward the direction close to the spectrometer box until it extends out of the fixed channel and is inserted into the first connection port to be electrically connected to the first connection port, thereby realizing the connection function of the connector.

[0014] Furthermore, the first sub-segment is provided with a first connection part. The light splitting box is provided with a second connection part, and when the connector is plugged into the corresponding connection port, the first connection part is connected to the second connection part. When the connector is withdrawn from the corresponding connection port, the first connection part is separated from the second connection part.

[0015] In this way, when the connector is connected to the corresponding first connecting port, the first connecting part and the second connecting part are connected. Since the first connecting part is arranged on the first sub-segment, the first sub-segment and the spectrometer box can be fixed together, that is, the ceramic tube, the optical fiber and the spectrometer box are fixed together. In this way, the first sub-segment can be prevented from moving under the elastic force of the elastic member, thereby preventing the connector from falling off from the corresponding first connecting port, so as to ensure the stability of the connection between the connector and the corresponding first connecting port.

[0016] Furthermore, the splitter box includes a plurality of splitter units, and a plurality of first connection ports are provided on a splitter unit. One of the plurality of first connection ports on a splitter unit is an input port, and the other plurality of first connection ports are output ports. The signal transmitted by the optical fiber connected to the input port can be distributed to the plurality of optical fibers connected to the plurality of output ports through the splitter unit.

[0017] Through the above arrangement, the optical splitter unit can distribute the signal transmitted by the optical fiber connected to the input port to multiple optical fibers connected to multiple output ports, and then transmit it to different users, thereby realizing the signal distribution function of the fiber splitter box.

[0018] Furthermore, the spectrometer box includes a box body and a plurality of spectrometers. The box body is provided with a plurality of installation channels, the plurality of installation channels are arranged at intervals, the plurality of spectrometers correspond to the plurality of installation channels one by one, and one spectrometer is installed in one installation channel. A plurality of plug-in channels are formed on one spectrometer, the axial direction of the plug-in channel is consistent with the axial direction of the installation channel where the spectrometer is located, and one spectrometer unit is plugged into one plug-in channel.

[0019] Through the above arrangement, multiple light splitters can be installed in multiple installation channels respectively, and then fixed on the box body, so as to integrate multiple light splitters together and install multiple light splitters in the box body. Since the light splitter unit and the light splitter are connected together by plugging, when the light splitter unit needs to be removed from the light splitter, for example, when the light splitter unit is to be inspected or maintained, the light splitter unit can be directly pulled out from the plugging channel to facilitate the inspection or maintenance of the light splitter unit, thereby facilitating the installation and use of the light splitter unit.

[0020] Furthermore, the plurality of light splitting elements are detachably connected to the box body. And / or the light splitting box is detachably connected to the housing.

[0021] In this way, the inspection and maintenance of the light splitter can be facilitated, and the use of the light splitter can be facilitated. The light splitter box and the light splitter installed on the light splitter box can be taken out of the box as a whole and used separately, which can provide flexibility when using the light splitter box and facilitate the use of the light splitter box and the light splitter.

[0022] Furthermore, the fiber distribution box also includes a remote unit and a transmission optical fiber. The remote unit is connected to the box, and the optical fiber connected to the input port is connected to the output end of the remote unit. The transmission optical fiber is connected to the input end of the remote unit, and the signal on the transmission optical fiber can be distributed to multiple optical fibers connected to the remote unit through the remote unit.

[0023] Through the above-mentioned setting, for two different fiber splitter boxes, the signal in one fiber splitter box can be transmitted to the telescopic unit on the other fiber splitter box through the telescopic unit and the transmission optical fiber on the other fiber splitter box, and then transmitted to the other fiber splitter box, and further transmitted to the user. In this way, through the setting of the telescopic unit and the transmission optical fiber, signal transmission between multiple fiber splitter boxes can be realized, and the signal can be transmitted to multiple users through multiple fiber splitter boxes, so that the signal on the fiber splitter box can be transmitted over a longer distance.

[0024] Further, the telemetry unit includes a housing and a light splitting unit. A plurality of second connection ports are formed on the housing, one of the plurality of second connection ports is a receiving port, and the other second connection ports are transmission ports. The receiving port is connected to the output end of the transmission optical fiber to receive the signal on the transmission optical fiber. The transmission port is connected to the input end of the optical fiber connected to the input port to transmit the signal to the input port.

[0025] Through the above arrangement, since the splitter can distribute the signal received by the remote unit to multiple transmission ports in unequal proportions, that is, the output powers of the multiple transmission ports can be different, the input end of the transmission optical fiber can be connected to the transmission port with the larger output power among the multiple transmission ports.

[0026] In this way, by connecting the transmission optical fiber through the higher-power output port and transmitting the signal to other fiber splitter boxes, the signal loss during transmission between the two fiber splitter boxes can be reduced, thereby improving the signal transmission efficiency and the signal transmission effect.

[0027] Furthermore, a light guide channel and a plurality of light splitting channels are formed on the light splitting part, the input end of the light guide channel is connected to the transmission optical fiber, and the output end of the light guide channel is respectively connected to the input ends of the plurality of light splitting channels. At least some of the plurality of light splitting channels have different widths.

[0028] Through the above arrangement, when the signal in the transmission optical fiber is transmitted to the light splitting part, it will first enter the light guiding channel and be transmitted along the light guiding channel until all the signals on the light guiding channel are distributed into multiple light splitting channels. Since the widths of at least some of the light splitting channels in the multiple light splitting channels are different. Therefore, when the signal in the light guiding channel is transmitted to the multiple light splitting channels, if the width of the light splitting channel is larger, a larger amount of signal will be transmitted into the light splitting channel, and if the width of the light splitting channel is smaller, the amount of signal transmitted into the light splitting channel will also be smaller, so as to realize the unequal distribution of the signal by the light splitting part, thereby realizing the signal transmission between multiple fiber splitting boxes.

[0029] Furthermore, the fiber distribution box also includes a fusion splicing tray, which is connected to the box body and is used to fuse the optical fiber and connect two different optical fibers.

[0030] In this way, when using the fiber splitter box, the staff can directly fuse and connect the optical fibers in the fiber splitter box. In this way, when optical fiber splicing is required, the staff does not need to carry or find tools for splicing optical fibers separately, which makes it convenient for the staff to use the fiber splitter box.

[0045] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0047] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0048] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0049] Fiber splitter boxes play an important role in optical fiber communication systems. They can connect optical fibers to devices and achieve terminal access to optical fibers.

[0050] In the related art, both ends of the optical fiber are connected with connectors, which include a shell, a ceramic tube and a tail handle. The tail handle is connected to the ceramic tube, and the shell is connected to the tail handle and is sleeved on the outside of the ceramic tube to protect the ceramic tube.

[0051] However, the structure of the above-mentioned optical fiber connector is relatively complex, resulting in a larger volume of the optical fiber connector. When more optical fibers are connected in the fiber splitter box, in order to meet the optical fiber connection requirements, the volume of the fiber splitter box also needs to be set larger, which will cause the fiber splitter box to occupy a larger space, thereby affecting the integration of the fiber splitter box.

[0052] Based on this, the present application provides a fiber splitter box, such as Figure 1 , Figure 2 As shown, the fiber splitter box 10 includes a box body 1 , a splitter box 2 and a plurality of optical fibers 3 .

[0053] Specifically, the box 1 includes an outer shell 11 and a cover. The outer shell 11 is formed with a receiving cavity 111 with an opening on one side. The cover is arranged at the opening and is movably connected to the outer shell 11 to open or close the opening. Specifically, the cover and the outer shell 11 are hinged together. The splitter box 2 and the multiple optical fibers 3 are all located in the receiving cavity 111. When using the fiber splitter box 10, the staff can rotate the cover to open the opening, so as to operate the multiple optical fibers 3 and the splitter box 2 inside. In some examples, the box 1 is in the shape of a rectangular parallelepiped, such as Figure 1 , Figure 3 As shown, in the first direction ( Figure 1 In the X direction shown in FIG. 1 , i.e., the length direction of the box 1 , the size of the box 1 is set to a, a=740 mm. Figure 1 , Figure 4 As shown, in the second direction ( Figure 1 In the Y direction shown in FIG. 1 , i.e., the height direction of the box 1 , the size of the box 1 is set to b, b = 580 mm. Figure 3 , Figure 4 As shown, in the third direction ( Figure 3In the Z direction shown in (ie, the width direction of the box 1), the size of the box 1 is set to c, c = 250 mm.

[0054] In some examples, a mounting bracket is connected to the outside of the box 1, and a mounting hole is opened on the mounting bracket. Screws are passed through the mounting hole, and the mounting bracket is screwed to the wall by screws. The box 1 can be connected to the wall through the mounting bracket, and can also be installed or placed in other suitable locations.

[0055] In some embodiments, Figure 1 As shown, the fiber distribution box 10 further includes a splice tray 4, which is connected to the box body 1, and specifically, the splice tray 4 is connected to the bottom wall of the accommodating cavity 111. The splice tray 4 is used to fuse the optical fiber 3 and connect two different optical fibers 3. Specifically, the splice tray 4 includes a docking port and a heater, and the bodies of two different optical fibers 3 can be docked together through the docking port, and then the bodies of the two optical fibers 3 are heated by the heater so that the docked ends of the bodies of the two optical fibers 3 are fused together to achieve the fusion between the different optical fibers 3.

[0056] In this way, when using the fiber splitter box 10, the staff can directly perform the fuse and connection work on the optical fiber 3 in the fiber splitter box 10. In this way, when the optical fiber 3 needs to be welded, the staff does not need to carry or find tools for welding the optical fiber 3 separately, which can facilitate the staff to use the fiber splitter box 10.

[0057] In some examples, such as Figure 1 As shown, a plurality of wire management grooves 1111 are provided on the bottom wall of the accommodating cavity 111 , and a plurality of optical fibers 3 can be constrained in the plurality of wire management grooves 1111 to facilitate the wiring and management of the plurality of optical fibers 3 .

[0058] like Figure 1 , Figure 2 As shown, the splitter box 2 is connected to the box body 1, and a plurality of first connection ports 2A are provided on the splitter box 2. A plurality of optical fibers 3 correspond to the plurality of first connection ports 2A one by one. The optical fiber 3 includes a body 31 and a connector 32. The connector 32 is connected to the end of the body 31, and can be plugged into or out of the corresponding first connection port 2A.

[0059] It should be noted that some of the first connection ports 2A among the plurality of first connection ports 2A are input ports of the splitter box 2, and another part of the first connection ports 2A among the plurality of first connection ports 2A are output ports of the splitter box 2. Signals on the plurality of optical fibers 3 connected to the plurality of input ports can be transmitted to the splitter box 2, and transmitted to the plurality of optical fibers 3 connected to the plurality of output ports on the splitter box 2 through the splitter box 2.

[0060] like Figure 2As shown, the connector 32 includes a tail handle 321. The tail handle 321 is formed with a fixed channel 3211, and the end of the body 31 is located in the fixed channel 3211 and connected to the tail handle 321. The tail handle 321 can produce elastic deformation along the extension direction of the fixed channel 3211, so that the tail handle 321 can switch between a compressed state and a natural state. When the connector 32 is plugged into the corresponding first connection port 2A, the tail handle 321 is in a compressed state, and when the connector 32 is withdrawn from the corresponding first connection port 2A, the tail handle 321 is in a natural state. Figure 2 As shown, the connector 32 further includes a ceramic tube 322. The ceramic tube 322 is located in the fixed channel 3211, and the end of the body 31 extends into the ceramic tube 322 and is connected to the ceramic tube 322. When the tail handle 321 is in a compressed state, the ceramic tube 322 extends to the side of the fixed channel 3211 close to the spectrometer box 2, and the end of the body 31 is electrically connected to the corresponding first connection port 2A. When the tail handle 321 is in a natural state, the ceramic tube 322 extends into the fixed channel 3211, and the end of the body 31 is separated from the corresponding first connection port 2A.

[0061] It should be noted that, when the connector 32 is plugged into the corresponding first connection port 2A, the end of the tail handle 321 close to the spectrometer box 2 will first abut against the spectrometer box 2, and then the tail handle 321 will produce elastic deformation along the extension direction of the fixed channel 3211, so that the length of the tail handle 321 in the extension direction of the fixed channel 3211 is shortened to shorten the extension length of the fixed channel 3211, thereby moving the ceramic tube 322 relative to the fixed channel 3211 so that the ceramic tube 322 extends out of the fixed channel 3211.

[0062] When the connector 32 withdraws from the corresponding first connection port 2A, the tail handle 321 releases the elastic potential energy stored in the compressed state, so that the tail handle 321 stretches along the extension direction of the fixed channel 3211, thereby extending the extension length of the fixed channel 3211 and moving the ceramic tube 322 relative to the fixed channel, so that the ceramic tube 322 retracts into the fixed channel 3211.

[0063] Exemplarily, the radial dimension of the fixing channel 3211 is equal to the maximum radial dimension of the ceramic tube 322 .

[0064] Exemplarily, the radial dimension of the fixed channel 3211 is slightly larger than the maximum radial dimension of the ceramic tube 322 .

[0065] Through the above arrangement, when the connector 32 is withdrawn from the corresponding first connection port 2A, the ceramic tube 322 is located in the fixed channel 3211, and the tail handle 321 can provide protection for the ends of the ceramic tube 322 and the body 31, thereby reducing the possibility of damage to the ceramic tube 322 and the body 31. When the connector 32 needs to be connected to the first connection port 2A, the tail handle 321 can be compressed to allow the ceramic tube 322 to extend out of the fixed channel 3211 and be electrically connected to the corresponding first connection port 2A, thereby realizing signal transmission between the optical fiber 3 and the splitter box 2.

[0066] By setting the tail handle 321, while ensuring that the connector 32 can be normally connected to the first connection port 2A, the tail handle 321 can also protect the ceramic tube 322 and the main body 31 that exit the first connection port 2A. In this way, there is no need to set up a shell to protect the ceramic tube 322, so that the ceramic tube 322 and the main body 31 can be protected. This can simplify the structure of the connector 32 and reduce the volume of the connector 32, thereby reducing the space occupied by the connector 32 in the box body 1. This can save space in the box body 1 to improve the integration of the fiber distribution box 10.

[0067] In some embodiments, Figure 2 , Figure 5 As shown, the tail handle 321 includes a first sub-segment 3212 and a second sub-segment 3213. The first sub-segment 3212 is connected to the body 31. When the connector 32 is plugged into the corresponding first connection port 2A, the second sub-segment 3213 is located at a side of the first sub-segment 3212 close to the spectrometer box 2. The tail handle 321 also includes an elastic member 3214, which is located between the first sub-segment 3212 and the second sub-segment 3213 and is connected to both the first sub-segment 3212 and the second sub-segment 3213. When the connector 32 is plugged into the corresponding first connection port 2A, the second sub-segment 3213 abuts against the spectrometer unit 211, and the first sub-segment 3212 and the second sub-segment 3213 squeeze the elastic member 3214, so that the tail handle 321 is in a compressed state.

[0068] Through the above arrangement, in the process of connecting the connector 32 and the first connection port 2A, the connector 32 and the first connection port 2A can be aligned first, and the second sub-segment 3213 can be abutted against the spectrometer box 2, and then the first sub-segment 3212 can be pushed to move toward the spectrometer box 2. During the movement of the first sub-segment 3212, the elastic member 3214 will be gradually compressed, and the distance between the first sub-segment 3212 and the second sub-segment 3213 will also be gradually shortened.

[0069] Since the ceramic tube 322 is connected to the main body 31, and the main body 31 is connected to the first sub-segment 3212, during the movement of the first sub-segment 3212, the ceramic tube 322 will move together with the first sub-segment 3212 toward the direction close to the spectrometer box 2 until it extends out of the fixed channel 3211 and is inserted into the first connection port 2A to be electrically connected to the first connection port 2A, thereby realizing the connection function of the connector 32.

[0070] It should be noted that the plugging of the connector 32 and the corresponding first connection port 2A refers to the plugging of the ceramic tube 322 on the connector 32 and the corresponding first connection port 2A.

[0071] It should be noted that, in the process of the connector 32 withdrawing from the corresponding first connection port 2A, the first sub-segment 3212 will first move in the direction away from the spectrometer box 2. At this time, under the action of the elastic force of the elastic member 3214, the second sub-segment 3213 will continue to abut against the spectrometer box 2, and the elastic member 3214 will gradually stretch until the elastic member 3214 returns to its natural state. The second sub-segment 3213 is separated from the spectrometer box 2, that is, the connector 32 completely withdraws from the corresponding first connection port 2A, and the tail handle 321 is in a natural state.

[0072] Exemplarily, the elastic member 3214 may be a rubber ring, which is located between the first sub-segment 3212 and the second sub-segment 3213 and connected to both the first sub-segment 3212 and the second sub-segment 3213 , and the ceramic tube 322 passes through the rubber ring and extends into the fixed channel 3211 corresponding to the second sub-segment 3213 .

[0073] Exemplarily, the elastic member 3214 includes a spring. For example, the elastic member 3214 includes a plurality of springs, and the plurality of springs are located between the first sub-segment 3212 and the second sub-segment 3213, and for any spring, one end of the spring is connected to the second sub-segment 3213, and the other end is connected to the first sub-segment 3212. The plurality of springs are arranged around the axial direction of the fixing channel 3211.

[0074] Alternatively, the elastic member 3214 includes a spring, one end of which is connected to the second subsection 3213 , and the other end of which is connected to the first subsection 3212 . The spring is sleeved on the ceramic tube 322 .

[0075] Based on the above, in some embodiments, such as Figure 5 As shown, a first connecting portion 321A is provided on the first sub-segment 3212. A second connecting portion 24 is provided on the light splitting box 2. When the tail handle 321 is in a compressed state, the first connecting portion 321A is connected to the second connecting portion 24. When the connector 32 is in a separated state, the first connecting portion 321A is separated from the second connecting portion 24.

[0076] In this way, when the connector 32 is connected to the corresponding first connection port 2A, the first connection part 321A is connected to the second connection part 24. Since the first connection part 321A is arranged on the first sub-segment 3212, the first sub-segment 3212 and the spectrometer box 2 can be fixed together, that is, the ceramic tube 322, the optical fiber 3 and the spectrometer box 2 are fixed together. In this way, the first sub-segment 3212 can be prevented from moving under the elastic force of the elastic member 3214, thereby preventing the connector 32 from falling off from the corresponding first connection port 2A, so as to ensure the stability of the connection between the connector 32 and the corresponding first connection port 2A.

[0077] In some examples, the first connection portion 321A includes a first hook, and the second connection portion 24 includes a second hook. When the connector 32 is in an assembled state, the first hook and the second hook are hooked together.

[0078] The first connection portion 321A may include a plurality of first hooks, and the second connection portion 24 may include a plurality of second hooks, and the plurality of first hooks correspond to the plurality of second hooks one by one. When the connector 32 is in the assembled state, the plurality of first hooks are located on two opposite sides of the connector 32, and correspondingly, the plurality of second hooks are also located on two opposite sides of the connector 32; or, the plurality of first hooks are arranged around the connector 32, and the plurality of second hooks are also arranged around the connector 32 and correspond to the plurality of first hooks, so as to further improve the stability of the connection between the connector 32 and the first connection port 2A.

[0079] In some examples, the first connection portion 321A includes a first magnetic member, and the second connection portion 24 includes a second magnetic member. When the connector 32 is connected to the first connection port 2A, the first magnetic member and the second magnetic member are magnetically attracted together.

[0080] Exemplarily, the first magnetic member is a magnetic block, and the second magnetic member is a magnetic sheet.

[0081] Exemplarily, the first magnetic member is a magnetic sheet, and the second magnetic member is a magnetic block.

[0082] In some embodiments, Figure 6 As shown, a plurality of light splitting units 211 are arranged on a light splitting box 2. Figure 7 As shown, a plurality of first connection ports 2A are disposed on one light splitting unit 211 .

[0083] One of the multiple first connection ports 2A on a splitter unit 211 is an input port for receiving a signal on an optical fiber 3 connected to the input port, and the other first connection port 2A is an output port for transmitting the signal received by the input port to multiple optical fibers 3 connected to multiple output ports.

[0084] Specifically, the multiple optical fibers 3 include multiple input optical fibers and multiple output optical fibers. The output ends of the multiple input optical fibers are connected to the multiple input ports on the multiple optical splitting units 211 through the connector 32, and are used to transmit signals to the multiple optical splitting units 211. The input ends of the multiple output optical fibers are connected to the multiple output ports on the multiple optical splitting units 211 through the connector 32, and are used to receive the signals distributed to the multiple output ports by the multiple optical splitting units 211. One optical splitting unit 211 is used to transmit the signal on one input optical fiber to multiple output optical fibers.

[0085] Through the above configuration, the optical splitter unit 211 can distribute the signal transmitted by the optical fiber 3 connected to the input port to multiple optical fibers 3 connected to multiple output ports, and then transmit it to different users, thereby realizing the signal distribution function of the fiber distribution box 10.

[0086] In some embodiments, Figure 8 , Fig. 9 As shown, the spectrometer box 2 includes a box body 25 and a plurality of spectrometers 21. The box body 25 is provided with a plurality of installation channels 22, which are arranged at intervals. The spectrometers 21 correspond to the installation channels 22 one by one, and one spectrometer 21 is installed in one installation channel 22.

[0087] In some examples, the axial directions of the plurality of mounting channels 22 are all consistent with the second direction, and the plurality of mounting channels are arranged in sequence along the first direction.

[0088] Through the above arrangement, the plurality of light splitters 21 can be respectively installed in the plurality of installation channels 22 and fixed on the box body 25 , so as to integrate the plurality of light splitters 21 together and realize the installation of the plurality of light splitters 21 in the box body 1 .

[0089] In some examples, the signals transmitted on the optical fiber 3 connected to one optical splitter 21 belong to the same operator network. Different operator networks transmit signals through different optical splitters 21 and are finally delivered to users through the optical fiber 3.

[0090] In this way, the wiring and distribution of multiple operator networks can be completed in one fiber distribution box 10, realizing centralized management of multiple operator networks. Compared with equipping each operator network with its own distribution box, it can realize integrated installation of multiple operator networks to facilitate the management of different operator networks.

[0091] Based on the above, in some examples, the appearance colors of multiple splitters 21 are different, and one operator network corresponds to a splitter 21 of one color. In this way, the splitters 21 corresponding to different operator networks can be quickly distinguished, thereby facilitating wiring, maintenance and other work, and facilitating the use of the fiber splitter box 10.

[0092] In other examples, the multiple optical splitters 21 may be marked with logos or names of the corresponding operator networks, which can also facilitate the use of the fiber splitter box 10 .

[0093] In some embodiments, Figure 8 , Fig.10 As shown, for any beam splitter 21 , a plurality of plugging channels are formed on the beam splitter 21 , and the axial directions of the plurality of plugging channels are consistent with the axial direction of the installation channel 22 where the beam splitter 21 is located, and one beam splitter unit 211 is plugged into one plugging channel.

[0094] It can be understood that the input port and the output port are located on both sides of the light splitting unit 211 in the axial direction of the plug-in channel.

[0095] Through the above configuration, multiple light splitting units 211 can be plugged into multiple light splitting components 21 to achieve installation of the light splitting units 211. The axial direction of the plugging channel is consistent with the axial direction of the installation channel 22, which can facilitate the insertion or removal of the light splitting unit 211 into or out of the light splitting component 21.

[0096] Since the spectrometer unit 211 and the spectrometer component 21 are connected together by plugging, when the spectrometer unit 211 needs to be removed from the spectrometer component 21, for example, when the spectrometer unit 211 is to be inspected or maintained, the spectrometer unit 211 can be directly pulled out from the plug-in channel to facilitate the inspection or maintenance of the spectrometer unit 211, thereby facilitating the installation and use of the spectrometer unit 211.

[0097] On the basis of the above, in some embodiments, multiple light splitters 21 are detachably connected to the box body 25. Specifically, multiple light splitters 21 are snap-fitted to multiple installation channels, which can facilitate the inspection and maintenance of the light splitters 21 and facilitate the use of the light splitters 21.

[0098] In some embodiments, the light splitting box 2 is detachably connected to the housing 1 .

[0099] In some examples, such as Figure 1 , Figure 6 As shown, a fixing bracket 23 is connected to the box body 25, and a screw hole is opened on the fixing bracket 23. A screw is passed through the screw hole. The fixing bracket 23 is screwed together with the side wall of the accommodating cavity 111 away from the opening through the screw, so as to fix the spectrometer box 2 in the accommodating cavity 111 and realize the detachable connection between the spectrometer box 2 and the box body 1.

[0100] In this way, the spectrometer box 2 and the spectrometer 21 installed on the spectrometer box 2 can be taken out of the housing 1 as a whole and used separately, which can provide flexibility in using the spectrometer box 2 and facilitate the use of the spectrometer box 2 and the spectrometer 21.

[0101] On this basis, in some examples, there are gaps between the multiple side walls of the spectrometer box 2 and the accommodating cavity 111 in the depth direction perpendicular to the accommodating cavity 111, so as to leave operating space for the spectrometer 21 on both sides of the axial direction of the installation channel 22, thereby facilitating the use of the spectrometer 21.

[0102] In order to facilitate signal transmission between different fiber distribution boxes 10, in some embodiments, such as Fig.11 As shown, the fiber distribution box 10 also includes a remote unit 5 and a transmission optical fiber 6. The remote unit 5 is connected to the box body 1, and the optical fiber 3 connected to the input port is connected to the output end of the remote unit 5. The transmission optical fiber 6 is connected to the input end of the remote unit 5, and the signal on the transmission optical fiber 6 can be distributed to multiple optical fibers 3 connected to the remote unit 5 through the remote unit 5.

[0103] It should be noted that one end of the transmission optical fiber 6 connected to the remote unit 5 is located inside the box 1, and the other end of the transmission optical fiber 6 is located outside the box 1. One end of the transmission optical fiber 6 on a fiber splitter box 10 is connected to the remote unit 5, and the other end of the transmission optical fiber 6 can be connected to the output end of the remote unit 5 in another fiber splitter box 10.

[0104] Through the above-mentioned setting, for two different fiber splitter boxes 10, the signal in one fiber splitter box 10 can be transmitted to the telescopic unit 5 on the other fiber splitter box 10 through the telescopic unit 5 and the transmission optical fiber 6 on the other fiber splitter box 10, and then transmitted to the other fiber splitter box 10, and further transmitted to the user. In this way, through the setting of the telescopic unit 5 and the transmission optical fiber 6, signal transmission between multiple fiber splitter boxes 10 can be realized, and the signal can be transmitted to multiple users through multiple fiber splitter boxes 10, so that the signal on the fiber splitter box 10 can be transmitted over a longer distance.

[0105] In some embodiments, Fig.12 As shown, the telescopic unit 5 includes a housing 51, and a plurality of second connection ports 5A are formed on the housing 51.

[0106] One of the plurality of second connection ports 5A is a receiving port, and the other plurality of second connection ports 5A are a plurality of transmission ports.

[0107] The receiving port is connected to the output end of the transmission optical fiber 6 to receive the signal on the transmission optical fiber 6. The transmission port is connected to the input end of the optical fiber 3 connected to the input port to transmit the signal to the input port.

[0108] In some examples, both ends of the delivery optical fiber 6 are connected with connectors 32. The receiving port is connected to the connector 32 on the output end of the delivery optical fiber 6.

[0109] It can be understood that the transfer port can be connected to the connector 32 on the input end of the optical fiber 3 connected to the input port of the splitter unit 211, and can also be connected to the connector 32 on the input end of the transfer optical fiber 6 on other fiber splitter boxes 10.

[0110] like Fig.12 As shown, the telescopic unit 5 further includes a spectrometer 52. The spectrometer 52 is disposed in the housing 51. The input end of the spectrometer 52 is connected to the receiving port, and the output end of the spectrometer 52 is connected to the transmission port. The spectrometer 52 is used to distribute the signal received by the receiving port to multiple transmission ports in unequal ratios.

[0111] Through the above arrangement, for two fiber splitter boxes 10 and the transmission optical fiber 6 connected therebetween, the transmission port of the remote unit 5 in one fiber splitter box 10 is connected to the input end of the transmission optical fiber 6, and the receiving port of the remote unit 5 in the other fiber splitter box 10 is connected to the output end of the transmission optical fiber 6, so as to realize the transmission of signals between the two fiber splitter boxes 10.

[0112] Since the spectrometer 52 can distribute the signal received by the telemetry unit 5 to multiple transmission ports in unequal proportions, that is, it can make the output powers of the multiple transmission ports different in magnitude, the input end of the transmission optical fiber 6 can be connected to the transmission port with the larger output power among the multiple transmission ports.

[0113] In this way, by connecting the transmission optical fiber 6 through the higher power output port and transmitting the signal to other fiber splitter boxes 10, the signal loss during transmission between the two fiber splitter boxes 10 can be reduced to improve the signal transmission efficiency and the signal transmission effect.

[0114] Based on the above, in some embodiments, such as Fig.13 As shown, a light guide channel 521 and a plurality of light splitting channels 522 are formed on the light splitting portion 52. The input end of the light guide channel 521 is connected to the receiving port, and the output end of the light guide channel 521 is respectively connected to the input ends of the plurality of light splitting channels 522. The plurality of light splitting channels 522 correspond to the plurality of transmission ports one by one, and the output end of one light splitting channel 522 is connected to one transmission port. At least some of the plurality of light splitting channels 522 have different widths.

[0115] Specifically, the splitting part 52 includes a light guiding fiber segment and multiple splitting fiber segments, a light guiding channel 521 is formed in the light guiding fiber segment, a splitting channel 522 is formed in a splitting fiber segment, and multiple splitting fiber segments are connected to the light guiding fiber segment so that signals are transmitted in the light guiding channel 521 and the multiple splitting channels 522.

[0116] Through the above arrangement, when the signal in the transmission optical fiber 6 is transmitted to the splitter part 52, it will first enter the light guiding channel 521, and be transmitted along the light guiding channel 521, and then be transmitted in turn to each splitter channel 522 connected to the light guiding channel 521, so as to distribute the signal in the light guiding channel 521 into multiple splitter channels 522.

[0117] Since at least some of the multiple split light channels 522 have different widths, when the signal in the light guide channel 521 is transmitted to the multiple split light channels 522, if the width of the split light channel 522 is large, a large amount of signal will be transmitted to the split light channel 522, and if the width of the split light channel 522 is small, the amount of signal transmitted to the split light channel 522 is also small, so as to realize unequal distribution of signals by the splitting part 52, thereby realizing signal transmission between multiple fiber distribution boxes 10.

[0118] In some examples, the plurality of light splitting channels 522 include a main light channel and a plurality of secondary light channels, the plurality of secondary light channels have the same width, and the width of the main light channel is greater than the width of the secondary light channel.

[0119] Specifically, the plurality of light splitting channels 522 include four secondary light channels, and the ratio of the width of the main light channel and the four secondary light channels is 28:3:3:3:3, that is, the main light channel accounts for 70% of the total power transmitted by the light guide channel 521, and the four secondary light channels jointly distribute 30% of the total power transmitted by the light guide channel 521. The main light channel is used to connect with the transmission optical fiber 6 on other fiber splitting boxes 10 to continue to transmit signals to other fiber splitting boxes 10, and the plurality of secondary light channels are connected with the optical fiber 3, and finally transmit the signal to the user.

[0120] Wherein, in the case of the above-mentioned ratio of the widths of the plurality of optical splitting channels 522 , signal transmission between three to five fiber splitting boxes 10 can generally be achieved.

[0121] Based on the above, in some examples, such as Fig.11 As shown, a secondary optical channel can be connected to a splitter unit 211 through an optical fiber 3 to transmit signals to multiple users. For example, a secondary optical channel is connected to a splitter unit 211 with a 1:4 equal split ratio through an optical fiber 3 to transmit signals to 4 users, and a remote unit 5 can transmit signals to 16 users and another fiber splitter box 10.

[0122] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0123] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
