Description

Technical Field

[0001] The present application relates to the technical field of optical cable connection, and in particular to an optical cable connection box. Background Art

[0002] With the development of fiber optic technology, the application of optical cables in communications has become popular. For example, more and more users use fiber optic broadband to access the Internet. Fiber optic cables can be brought into the home through fiber optic access termination (FAT).

[0003] For example, when suppliers are initially building a network, they can install fiber optic splitter boxes on communication poles in residential areas. When users apply for network access services, they can simply connect the incoming fiber optic cable to the nearest fiber optic splitter box.

[0004] However, when suppliers initially build a network, they need to first obtain the right to use the communication poles. The period for obtaining the right to use the communication poles is relatively long, which will delay the progress of network construction and extend the period of fiber optic network deployment. Summary of the Invention

[0005] The present application provides an optical cable connection box and an adapter, which can overcome the problem of long initial fiber optic network deployment in related technologies. The technical solution is as follows:

[0006] On the one hand, an optical cable connection box is provided, which includes a box body, at least one pair of adapters and at least one optical fiber, each adapter including a first interface and a second interface positioned opposite to each other; the at least one pair of adapters is located on the box body, and the first interface of each adapter is located outside the box body, and the second interface of each adapter is located inside the box body; the at least one optical fiber is located in the box body and connected between the second interfaces of each pair of adapters.

[0007] The optical cable connection box may include at least one pair of adapters, for example, a pair of adapters, or two pairs of adapters. This embodiment does not limit the number of pairs of adapters, and a pair of adapters may be used as an example. A pair of adapters may include two adapters, which may be respectively referred to as a first adapter and a second adapter.

[0008] In the solution shown in the present application, the optical cable located on the left side of the optical cable connection box and the optical cable located on the right side of the optical cable connection box are indirectly connected through a first adapter installed on the left wall of the box body, an optical fiber located in the box body, and a second adapter installed on the right wall of the box body. For example, the optical fiber connector of the optical cable located on the left side of the optical cable connection box is inserted into the first interface of the first adapter on the left wall, and the optical fiber connector of the optical cable located on the right side of the optical cable connection box is inserted into the first interface of the second adapter on the right wall. The first interface of the first adapter and the second interface of the second adapter are connected through the optical fiber, thereby achieving docking of the optical cable located on the left side of the optical cable connection box and the optical cable located on the right side of the optical cable connection box through the optical cable connection box.

[0009] In a possible implementation manner, the number of the optical fibers is related to the number of optical cables connected to the optical cable connection box and the number of optical fibers included in each optical cable.

[0010] In the solution shown in this application, each side of the optical cable connection box is connected to n optical cables, each of which has m optical fibers, so the number of optical fibers is m × n. For example, each side of the optical cable connection box is connected to one optical cable, each of which has two optical fibers, so the number of optical fibers is two.

[0011] In one possible embodiment, each adapter is a multi-core adapter, the first interface includes multiple sockets, the second interface includes multiple sockets, and each pair of adapters includes a first adapter and a second adapter; the first connector of each optical fiber is inserted into any socket of the second interface of the first adapter, and the second connector of each optical fiber is inserted into any socket of the second interface of the second adapter.

[0012] For example, the first optical cable on the left side of the optical cable connection box has two optical fibers, labeled 1 and 2, and the second optical cable on the right side of the optical cable connection box has two optical fibers, labeled 1 and 2. If the technician intends to connect optical fiber 1 of the first optical cable to optical fiber 1 of the second optical cable, and optical fiber 2 of the first optical cable to optical fiber 2 of the second optical cable, then the two optical fibers in box body 1 can be directly connected between the second interface of the first adapter and the second interface of the second adapter. If the technician intends to connect optical fiber 1 of the first optical cable to optical fiber 2 of the second optical cable, and optical fiber 2 of the first optical cable to optical fiber 1 of the second optical cable, then the two optical fibers in the box body can be connected between the second interface of the first adapter and the second interface of the second adapter in a crossover manner.

[0013] It can be seen that by indirectly connecting two optical cables through optical fibers, the line sequence of the optical fiber connections in the optical cable can be adjusted, thereby improving the flexibility of use of the optical cable connection box.

[0014] In a possible implementation manner, the at least one pair of adapters is located on a box wall of the box body.

[0015] In the solution shown in the present application, the adapter can be installed on the box wall of the box body, can also be installed on the box cover of the box body, can also be installed on the box seat of the box body, etc.

[0016] On the other hand, an adapter is provided, which includes a first interface, a second interface and a fixed flange; the first interface and the second interface have the same structure and are located on both sides of the fixed flange.

[0017] The first interface and the second interface have the same structure and are located on either side of the fixed flange. For example, the first interface and the second interface can be symmetrical about the fixed flange. Of course, the first interface and the second interface can also be asymmetrical about the fixed flange. This embodiment is not limited to this, and any adapter that can connect to the optical fiber connector of the optical cable through the first interface and the second interface is sufficient.

[0018] In this way, during network deployment before obtaining access to the current pole, the optical cable leading from the previous pole to the current pole can be connected to the first port of the adapter. The optical cable leading to the next pole can then be connected to the second port of the adapter. This eliminates the need for technicians to wait until access to the current pole is obtained before continuing network deployment, saving time and shortening the network deployment cycle. Later, after obtaining access to the current pole, the optical cable junction box at the current pole can be simply replaced with a fiber optic splitter box, simplifying the operation and saving time.

[0019] In a possible implementation manner, the adapter is a detachable adapter including a first body portion and a second body portion in an axial direction, and the first body portion and the second body portion are assembled to form the adapter.

[0020] The first body portion and the second body portion may be two parts separated along a center plane in a length direction of the adapter.

[0021] In this way, when inserting the optical cable into the adapter, the first body portion and the second body portion can be separated, and the optical fiber connector of the optical cable on the left side of the adapter can be placed in the first interface with its ferrule located in the protective cover, while the optical fiber connector of the optical cable on the right side of the adapter can be placed in the second interface with its ferrule located in the protective cover. This can prevent the ferrule from being damaged during the insertion of the optical cable into the adapter, thereby protecting the ferrule of the inserted optical cable.

[0022] In a possible embodiment, a limiting sleeve is provided inside the adapter at a position corresponding to the fixing flange, the wall of the limiting sleeve is elastic, and the fiber cores of the two optical cables respectively inserted into the first interface and the second interface are located in the limiting sleeve.

[0023] In one example, the ferrules of the optical cable led from the first interface of the adapter and the optical cable led from the second interface of the adapter are docked in the limiting sleeve. Docking in the limiting sleeve can improve the accuracy of optical cable docking.

[0024] In a possible implementation, the adapter further includes a protective sleeve, the protective sleeve is interference-fitted into the limiting sleeve, and the ferrules of the two optical cables respectively inserted into the first interface and the second interface are located in the protective sleeve.

[0025] In one example, the protective sleeve is flexible and can protect the ferrule of the optical cable located therein.

[0026] In a possible implementation manner, a plurality of strip-shaped notches are provided on the wall of the limiting sleeve along the length direction, so that the wall of the limiting sleeve has elasticity.

[0027] In one example, because the wall of the limiting sleeve is elastic, the protective sleeve can be interference fit in the limiting sleeve. For example, when inserting the protective sleeve into the limiting sleeve, the elastic wall of the limiting sleeve can be slightly pried apart to allow the protective sleeve to fit into the limiting sleeve. In this way, the protective sleeve can be firmly positioned in the limiting sleeve. The protective sleeve is flexible, and although its outer wall is tightly pressed by the elastic wall of the limiting sleeve, its inner wall is flexible and will not damage the ferrule inside. It can also improve the stability of the ferrule in the protective sleeve. Once the stability of the ferrules of the two optical cables in the protective sleeve is improved, the alignment accuracy of the ferrules will also be improved.

[0028] On the other hand, an optical cable connection box is also provided, which includes a box body and any one of the above-mentioned adapters, and the adapter is fixed in the box body through the fixing flange; the box body has a first optical cable port and a second optical cable port on the box wall, the position of the first optical cable port is opposite to the position of the first interface, and the position of the second optical cable port is opposite to the position of the second interface; the optical cable located on one side of the optical cable connection box can pass through the first optical cable port and be inserted into the first interface, and the optical cable located on the other side of the optical cable connection box can pass through the second optical cable port and be inserted into the second interface.

[0029] In this way, the optical cable on the left side of the optical cable connection box can pass through the first optical cable port on the left box wall and be inserted into the first interface of the adapter. The optical cable on the right side of the optical cable connection box can pass through the second optical cable port on the right box wall and be inserted into the second interface of the adapter. The optical cables on both sides of the optical cable connection box can be connected through the optical cable connection box.

[0030] In a possible embodiment, the fixing flange has an arcuate groove along the circumferential direction, the box body has an arcuate protrusion adapted to the arcuate groove, and the fixing flange is fixed in the box body by the arcuate protrusion being located in the arcuate groove.

[0031] In this way, when the adapter is seated in the box body, the arc-shaped protrusion of the box body is stuck in the arc-shaped groove of the fixing flange, and then the box cover is closed on the box seat, thereby pressing the adapter into the box body.

[0032] In a possible implementation manner, both the first optical cable port and the second optical cable port have flexible pads.

[0033] In one example, both the first and second optical cable ports may have flexible pads, and the first and second optical cable ports are used for passing optical cables. Thus, the flexible pads in the first and second optical cable ports can protect the passing optical cables. Furthermore, the flexible pads also act as seals, tightly fitting the flexible pads against the optical cable ports to prevent water and dust from entering the box through the gap between the optical cable and the optical cable ports.

[0034] The beneficial effects of the technical solutions provided in the embodiments of the present application include at least:

[0035] In an embodiment of the present application, the optical cable junction box includes an adapter. During network deployment without obtaining access to the current communication pole, the optical cable leading from the previous communication pole to the current communication pole can be inserted into the adapter. The optical cable leading to the next communication pole can then be inserted into the adapter. This eliminates the need for technicians to wait until access to the current communication pole is obtained before continuing network deployment, saving network deployment time and shortening the network deployment cycle. Later, after obtaining access to the current communication pole, the optical cable junction box at the current communication pole can be directly replaced with a fiber optic splitter box, simplifying the operation and saving time.

[0057] An embodiment of the present application provides an optical cable splice box that can be used to connect two optical cables. For example, the box can be used to connect two outdoor optical cables. For another example, the box can also be used to connect an outdoor optical cable and a home optical cable. As an example, the optical fiber connector at the end of the optical cable can be inserted into the cable splice box, and the two optical cables can be connected through the cable splice box.

[0058] A possible application scenario of the optical cable connection box may be that multiple optical fiber access terminals (FATs) are arranged between the data center (Center Office, CO) and the user. When the distance between two adjacent optical fiber access terminals is relatively far, multiple optical cables will be used, and the two adjacent optical cables can be connected through the optical cable connection box.

[0059] Another possible use case for this cable junction box is that, during network deployment, fiber optic splitter boxes are deployed in residential areas near data centers. When users apply for network access, they can connect the incoming fiber optic cable from the nearest fiber optic splitter box and bring it into their homes. Fiber optic splitter boxes are usually installed on communication poles. Before obtaining the right to use the communication poles, this cable junction box can be used to temporarily replace the fiber optic splitter box without delaying the network deployment process. Later, after obtaining the right to use the communication poles, the fiber optic splitter box can be used to replace the cable junction box. This shows that the period during which the right to use the communication poles is obtained does not affect the progress of network deployment, which can shorten the network deployment cycle.

[0060] For example, Figure 1As shown, there are four residential areas near the data center that require network deployment, designated as the first, second, third, and fourth residential areas. A fiber optic splitter box needs to be installed on the first communication pole 10 in the first residential area, a fiber optic splitter box on the second communication pole 20 in the second residential area, a fiber optic splitter box on the third communication pole 30 in the third residential area, and a fiber optic splitter box on the fourth communication pole 40 in the fourth residential area. The first, third, and fourth communication poles 10, 30, and 40 have usage rights, but the second communication pole 20 does not yet have usage rights.

[0061] Then, in network deployment, if Figure 1 As shown, optical fiber splitter boxes 200 can be installed on the first communication pole 10, the third communication pole 30, and the fourth communication pole 40, respectively. At the second communication pole 20, the optical cable junction box 100 temporarily connects the first optical cable to the second optical cable. The first optical cable is the optical cable leading from the first communication pole 10, and the second optical cable is the optical cable leading to the third communication pole 30. This allows technicians to continue network deployment without having to wait until they obtain the right to use the second communication pole 20. After obtaining the right to use the second communication pole 20, the optical cable junction box 100 at the second communication pole 20 can be directly replaced with the optical fiber splitter box 200. This simplifies operation, saves time, and shortens the network deployment cycle.

[0062] Among them, the optical cable connection box is smaller in size and occupies less space on the communication pole when installed on it, so there is no need to obtain the right to use the communication pole. The optical fiber distribution box has more devices inside and will also lead out multiple household optical cables, etc. Its size is larger, so when it is installed on a communication pole, it is necessary to have the right to use the communication pole.

[0063] The optical cable connected by the optical cable connection box may be a single-core optical cable, a dual-core optical cable, or a multi-core optical cable, etc., which is not limited in this embodiment.

[0064] The above are possible application scenarios of the optical cable connection box. The specific structure of the optical cable connection box will be introduced below.

[0065] like Figure 2 As shown, the optical cable connection box includes a box body 1, at least one pair of adapters 2 and at least one optical fiber 3, each adapter 2 includes a first interface 21 and a second interface 22 positioned opposite to each other; at least one pair of adapters 2 is located on the box body 1, and the first interface 21 of each adapter 2 is located outside the box body 1, and the second interface 22 of each adapter 2 is located inside the box body 1; at least one optical fiber 3 is located in the box body 1 and is connected between the second interfaces 22 of each pair of adapters 2.

[0066] In one example, the box body 1 may be cylindrical or cubic in shape, etc., which is not limited in this embodiment. Figure 2 As shown, the box body 1 may include a box cover 14 and a box seat 15, wherein the box cover 14 covers the box seat 15 to form the box body 1. Regarding the shapes of the box cover 14 and the box seat 15, technicians can flexibly select them according to actual conditions.

[0067] For example, the box cover 14 may have a semi-columnar structure, and the box base 15 may also have a semi-columnar structure. The semi-columnar structure is a structure that is cut in half along the length direction of the columnar structure. In this way, after the box cover 14 is snapped onto the box base 15, a cylindrical box body 1 can be obtained. For another example, the box cover 14 may have a semi-columnar structure, and the box base 15 may have a plate-like structure that matches the box cover 14. The box wall of the box cover 14 is fixed to the box base 15 of the plate-like structure, thereby obtaining a semi-columnar box body 1. For another example, the box cover 14 may have a plate-like structure, and the box base 15 may have a semi-columnar structure. The plate-like box cover 14 is fixed to the box wall of the box base 15, thereby obtaining a semi-columnar box body 1.

[0068] For another example, the box cover 14 is a bottomless rectangular cubic column, the box base 15 is a uncovered rectangular cubic column, and the box wall of the box cover 14 and the box wall of the box base 15 are fixed to each other, resulting in a box body 1 that is a rectangular cubic column. For another example, the box cover 14 is a bottomless rectangular cubic column, the box base 15 is a plate-like structure, and the box wall of the box cover 14 is fixed to the plate-like box base 15, resulting in a box body 1 that is a rectangular cubic column. For another example, the box cover 14 is a plate-like structure, the box base 15 is a uncovered rectangular cubic column, and the plate-like box cover 14 is fixed to the box wall of the box base 15, resulting in a box body 1 that is a rectangular cubic column.

[0069] The present embodiment does not limit the specific structures of the box cover 14 and the box seat 15 of the box body 1 , and it is sufficient that the box body 1 with a closed space is obtained by snapping the box cover 14 onto the box seat 15 .

[0070] In one example, there are multiple ways to mount the box cover 14 and the box seat 15. For example, one mounting method may be that the box cover 14 and the box seat 15 are hinged, and the box cover 14 is snapped onto the box seat 15. The box cover 14 can be unscrewed from the box seat 15 to facilitate certain operations by technicians. For another example, another mounting method may be that the box cover 14 and the box seat 15 are mounted together with screws. When a technician needs to open the box body 1 to perform certain operations, he needs to unscrew the screws. This embodiment does not limit the mounting method between the box cover 14 and the box seat 15.

[0071] In one example, in order to protect the components inside the box body 1 and prevent rainwater, dust, etc. from entering the box body 1, a sealing gasket is installed between the box cover 14 and the box seat 15 to improve the sealing between the box cover 14 and the box seat 15, thereby protecting the components inside the box body 1.

[0072] As described above, each pair of adapters 2 is located on the box body 1, with the first interface 21 of each adapter 2 located outside the box body, and the second interface 22 of each adapter 2 located inside the box body 1. For example, the adapters 2 may be located on the box wall of the box body 1, or on the box cover 14 of the box body 1, or on the box seat 15 of the box body 1. This embodiment does not limit whether the adapters 2 are located on the box wall, the box cover 14, or the box seat 15; the adapters 2 can be located on the box wall for example.

[0073] As an example, the box body 1 may have two optical cable ports on its wall, one for mounting the first adapter 2c, and the other for mounting the second adapter 2d. These two optical cable ports may be referred to as the first optical cable port and the second optical cable port, respectively. For example, the first adapter 2c may be mounted in the first optical cable port, with the first interface 21 of the first adapter 2c extending outside the box body 1 and the second interface 22 of the first adapter 2c located inside the box body 1. The second adapter 2d may be mounted in the second optical cable port, with the first interface 21 of the second adapter 2d extending outside the box body 1 and the second interface 22 of the second adapter 2d located inside the box body 1.

[0074] The first and second optical cable ports may be provided with flexible pads to protect the adapter 2 installed therein. Furthermore, the flexible pads also function as seals, fitting tightly against the optical cable ports to prevent water and dust from entering the box through the gap between the adapter 2 and the optical cable ports.

[0075] The adapter 2 is installed in the optical cable port, that is, the fixing flange of the adapter 2 is located in the optical cable port and is fixed to the box wall where the optical cable port is located by a fixing nut. The first interface 21 of each adapter 2 extends out of the box body 1, and the second interface 22 of each adapter 2 is located inside the box body 1.

[0076] The above is an introduction to the structure of the box body 1 of the optical cable connection box. The adapter 2 of the optical cable connection box will be introduced below. The adapter 2 can be an ordinary adapter, including two relatively positioned interfaces, one interface is used to connect the jumper fiber, and the other interface is used to connect the optical cable. The jumper fiber is an optical fiber with optical fiber connectors at both ends.

[0077] The optical cable connection box may include at least one pair of adapters 2, for example, a pair of adapters 2, or two pairs of adapters 2. This embodiment does not limit the number of pairs of adapters 2, and a pair of adapters 2 may be used as an example. The pair of adapters 2 may include two adapters, which may be respectively designated as a first adapter 2c and a second adapter 2d.

[0078] In one example, if the optical cable connected to the optical cable connection box is a single-core cable, the first adapter 2c and the second adapter 2d are both single-core adapters. If the optical cable connected to the optical cable connection box is a dual-core cable, the first adapter 2c and the second adapter 2d are both dual-core adapters. If the optical cable connected to the optical cable connection box is a multi-core cable, the first adapter 2c and the second adapter 2d are both multi-core adapters. This embodiment does not limit whether the optical cable is single-core or multi-core. The accompanying drawings use a dual-core optical cable as an example. Accordingly, the first adapter 2c and the second adapter 2d are both dual-core adapters.

[0079] Continuing with Figure 2 , first adapter 2c and second adapter 2d are connected via optical fiber 3. If adapter 2 is a single-core adapter, there is one optical fiber 3, while if adapter 2 is a duplex adapter, there are two optical fibers 3. Thus, second interface 22 of first adapter 2c and second interface 22 of second adapter 2d are connected via optical fiber 3.

[0080] The optical fiber connected between the first adapter 2c and the second adapter 2d may also be a patch cord, which is an optical fiber with optical fiber connectors at both ends.

[0081] In this way, the optical cable located on the left side of the optical cable connection box and the optical cable located on the right side of the optical cable connection box are indirectly connected via the first adapter 2c installed on the left wall of the box body 1, the optical fiber 3 located in the box body 1, and the second adapter 2d installed on the right wall of the box body 1. For example, the optical fiber connector of the optical cable located on the left side of the optical cable connection box is inserted into the first interface 21 of the first adapter 2c on the left wall, and the optical fiber connector of the optical cable located on the right side of the optical cable connection box is inserted into the first interface 21 of the second adapter 2d on the right wall. The first interface 22 of the first adapter 2c and the second interface 22 of the second adapter 2d are connected via the optical fiber 3, thereby achieving docking of the optical cable located on the left side of the optical cable connection box and the optical cable located on the right side of the optical cable connection box through the optical cable connection box.

[0082] Based on the above, the optical cable connection box includes a box body 1, at least one pair of adapters 2 and at least one optical fiber 3, and each pair of adapters 2 is connected through at least one optical fiber 3. In the scenario of network deployment and the right to use the current communication pole has not been obtained, the optical cable leading from the previous communication pole to the current communication pole can be connected to the first interface 21 of one adapter 2 in the pair of adapters, and then the optical cable leading to the next communication pole can be connected to the first interface 21 of the other adapter 2 in the pair of adapters. In this way, technicians do not need to wait until they obtain the right to use the current communication pole before continuing with network deployment, which can save network deployment time and shorten the network deployment cycle. After obtaining the right to use the current communication pole at a later stage, the optical cable connection box at the current communication pole can be directly replaced with a fiber optic splitter box, which is simple to operate and saves time.

[0083] Moreover, the optical cable connection box can be used to connect the optical fiber splitter box on the previous communication pole and the optical fiber splitter box on the next communication pole, so that the connection between the optical fiber splitter box on the previous communication pole and the optical fiber splitter box on the next communication pole will not be affected due to the inability to install the optical fiber splitter box on the current communication pole, thereby not delaying the network use in the residential area where the next communication pole is located.

[0084] The number of optical fibers 3 is related to the number of optical cables 4 connected to the optical cable connection box and the number of optical fibers included in each optical cable 4 .

[0085] For example, each side of the optical cable connection box is connected to n optical cables 4, and each optical cable 4 has m optical fibers. Then, the number of optical fibers 3 is m×n. Figure 9 As shown, each side of the optical cable connection box is connected to an optical cable 4, and each optical cable 4 has two optical fibers. Therefore, the number of optical fibers 3 is two.

[0086] In the scenario where the optical cable inserted into the optical cable connection box is a multi-core optical cable, the line sequence of the optical cable connection can be adjusted through the multiple optical fibers 3 in the box body 1. The specific implementation structure can be as follows:

[0087] like Figure 2 and Figure 3 As shown, each adapter 2 is a multi-core adapter, the first interface 21 includes multiple sockets, the second interface 22 includes multiple sockets, and each pair of adapters 2 includes a first adapter 2c and a second adapter 2d; the first connector 31 of each optical fiber 3 is inserted into any socket of the second interface 22 of the first adapter 2c, and the second connector 32 of each optical fiber 3 is inserted into any socket of the second interface 22 of the second adapter 2d.

[0088] For example, the adapter 2 is a dual-socket adapter. The first interface 21 of the first adapter 2c includes two sockets, which are used to connect to the optical fiber connector of a duplex optical cable. The second interface 22 of the first adapter 2c includes two sockets, which are used to connect to the optical fiber 3 inside the box body 1. Similarly, the first interface 21 of the second adapter 2d includes two sockets, which are used to connect to the optical fiber connector of a duplex optical cable. The second interface 22 of the second adapter 2d includes two sockets, which are used to connect to the optical fiber 3 inside the box body 1.

[0089] The adapter 2 is a pair of dual-socket adapters. Accordingly, there are two optical fibers 3, which can be designated as a first optical fiber and a second optical fiber. The first connector 31 of the first optical fiber can be inserted into any socket of the second interface 22 of the first adapter 2c, and the second connector 32 of the first optical fiber can be inserted into any socket of the second interface 22 of the second adapter 2d. The first connector 31 of the second optical fiber can be inserted into the remaining socket of the second interface 22 of the first adapter 2c, and the second connector 32 of the second optical fiber can be inserted into the remaining socket of the second interface 22 of the second adapter 2d.

[0090] For example, the first optical cable on the left side of the optical cable connection box has two optical fibers, which are marked as No. 1 and No. 2, and the second optical cable on the right side of the optical cable connection box has two optical fibers, which are marked as No. 1 and No. 2. If the technician intends to connect No. 1 of the first optical cable to No. 1 of the second optical cable, and No. 2 of the first optical cable to No. 2 of the second optical cable, then the two optical fibers 3 in the box body 1 can be connected as follows: Figure 2 In the direct connection shown, the optical fibers 3 are connected between the second interface 22 of the first adapter 2c and the second interface 22 of the second adapter 2d. If the technician intends to connect the No. 1 of the first optical cable to the No. 2 of the second optical cable, and the No. 2 of the first optical cable to the No. 1 of the second optical cable, then the two optical fibers 3 in the box body 1 can be connected as shown below. Figure 3 The cross-connection shown is connected between the second interface 22 of the first adapter 2c and the second interface 22 of the second adapter 2d.

[0091] It can be seen that by indirectly connecting two optical cables through the optical fiber 3, the line sequence of the optical fiber connections in the optical cable can be adjusted, thereby improving the flexibility of use of the optical cable connection box.

[0092] In one example, when no optical cables are inserted into the two sides of the optical cable connection box, in order to protect the first interface 21 located outside the box body 1, the adapter 2 further includes a dust cap 28. Figure 4 and Figure 5 As shown, when no optical cable is inserted into the first interface 21 of the first adapter 2c on the left side of the optical cable connection box, a dust cap 28 may be inserted thereon to prevent water and dust from entering the first interface 21 and affecting the alignment accuracy of the optical cable. Figure 4 and Figure 5 As shown, when no optical cable is inserted into the first interface 21 of the second adapter 2d on the right side of the optical cable connection box, a dust cap 28 may be inserted thereon to prevent water and dust from entering the first interface 21 and affecting the alignment accuracy of the optical cable.

[0093] In one example, since the optical cable can be directly plugged into the first interface 21 of the first adapter 2c and the second adapter 2d, extending from the exterior of the box body 1, without opening the box body 1, the fixing method between the box cover 14 and the box seat 15 can be removable or non-removable. When using this optical cable connection box to connect two optical cables, technicians can directly plug the optical cables into the first interface 21 exposed on the exterior of the box body 1 without opening the box body 1, which simplifies the operation and improves operational efficiency.

[0094] In a possible usage scenario, when no optical cables are inserted into the two sides of the optical cable connection box, dust caps 28 are installed on the first interfaces 21 of the first adapter 2c and the second adapter 2d extending outside the box body 1 to protect the first adapter 2c and the second adapter 2d. When the optical cable connector is used to connect optical cables, if the optical cable on the left and the optical cable on the right are directly connected, the box body 1 is opened and the two optical fibers 3 in the box body 1 are connected as shown in the following figure. Figure 4 In the direct connection method shown, the first adapter 2c and the second adapter 2d are inserted into the second interface 22 located in the box body 1. Afterwards, the dust cap 28 is removed and the left optical cable is directly inserted into the first interface 21 of the first adapter 2c installed on the left wall of the box body 1, and the right optical cable is inserted into the first interface 21 of the second adapter 2d installed on the right wall of the box body 1. Figure 6 The structural diagram shown.

[0095] If the optical cable on the left and the optical cable on the right are connected in a cross connection mode, then the box body 1 is opened and the two optical fibers 3 in the box body 1 are connected in a cross connection mode. Figure 5 The optical fiber cable on the left is inserted into the first interface 21 of the first adapter 2c installed on the left wall of the box body 1, and the optical fiber cable on the right is inserted into the first interface 21 of the second adapter 2d installed on the right wall of the box body 1. Figure 7 The structural diagram shown.

[0096] In an embodiment of the present application, the optical cable connection box includes a box body 1, at least one pair of adapters 2 and at least one optical fiber 3, and each pair of adapters 2 is connected through at least one optical fiber 3. In a scenario where the network is deployed and the right to use the current communication pole has not been obtained, the optical cable leading from the previous communication pole to the current communication pole can be connected to the first interface 21 of one adapter 2 in a pair of adapters, and then the optical cable leading to the next communication pole can be connected to the first interface 21 of the other adapter 2 in the pair of adapters. In this way, technicians do not need to wait until they obtain the right to use the current communication pole before continuing with network deployment, which can save network deployment time and shorten the network deployment cycle. After obtaining the right to use the current communication pole at a later stage, the optical cable connection box at the current communication pole can be directly replaced with a fiber optic splitter box, which is simple to operate and saves time.

[0097] Moreover, the optical cable connection box can be used to connect the optical fiber splitter box on the previous communication pole and the optical fiber splitter box on the next communication pole, so that the connection between the optical fiber splitter box on the previous communication pole and the optical fiber splitter box on the next communication pole will not be affected due to the inability to install the optical fiber splitter box on the current communication pole, thereby not delaying the network use in the residential area where the next communication pole is located.

[0098] The present application also provides an adapter, which can replace the above-mentioned optical cable connection box to achieve the connection between two optical cables.

[0099] like Figure 8 As shown, the adapter 2 may include a first interface 21 , a second interface 22 and a fixing flange 23 , wherein the first interface 21 and the second interface 22 have the same structure and are located on both sides of the fixing flange 23 .

[0100] In one example, Figure 8 As shown, the adapter 2 may include a first interface 21, a second interface 22, and a fixing flange 23. The first interface 21 and the second interface 22 are located on either side of the fixing flange 23. For example, the first interface 21 is located on the left side of the fixing flange 23, and the second interface 22 is located on the right side of the fixing flange 23. Since both the first interface 21 and the second interface 22 are used to connect optical cables, the first interface 21 and the second interface 22 have the same structure. For example, the first interface 21 and the second interface 22 are symmetrical about the fixing flange 23. Of course, the first interface 21 and the second interface 22 do not need to be symmetrical about the fixing flange 23.

[0101] As described above, the optical cable connected to the adapter 2 can be a single-core optical cable, a dual-core optical cable, or a multi-core optical cable. The adapter 2 is adapted to the optical cable to which it is connected. For example, if the optical cable is a single-core optical cable, each interface of the adapter 2 has a core channel. For example, the first interface 21 and the second interface 22 each have a socket. For another example, if the optical cable is a dual-core optical cable, each interface of the adapter 2 has two sockets. For example, Figure 8 As shown, the first interface 21 and the second interface 22 each have two sockets.

[0102] Because the first interface 21 and the second interface 22 of the adapter 2 have the same structure, both the first interface 21 and the second interface 22 can be used to connect optical cables. For example, the optical fiber connector of the optical cable on the left side of the adapter 2 can be plugged into the first interface 21, and the optical fiber connector of the optical cable on the right side of the adapter 2 can be plugged into the second interface 22, thereby connecting the two optical cables.

[0103] In this way, during network deployment without obtaining access to the current communication pole, the optical cable leading from the previous communication pole to the current communication pole can be connected to the first interface 21 of adapter 2, and the optical cable leading to the next communication pole can be connected to the second interface 22 of adapter 2. This eliminates the need for technicians to wait until access to the current communication pole is obtained before continuing network deployment, saving time and shortening the network deployment cycle. Later, after obtaining access to the current communication pole, the optical cable junction box at the current communication pole can be directly replaced with a fiber optic splitter box, which is simple to operate and saves time.

[0104] Moreover, the fiber optic splitter box on the previous communication pole can be connected to the fiber optic splitter box on the next communication pole through adapter 2, so that the connection between the fiber optic splitter box on the previous communication pole and the fiber optic splitter box on the next communication pole will not be affected due to the inability to install the fiber optic splitter box on the current communication pole, thereby not delaying the network use in the residential area where the next communication pole is located.

[0105] In one example, the ferrules of the optical cable from the first interface 21 of the adapter 2 and the optical cable from the second interface 22 of the adapter 2 are connected at the position corresponding to the fixing flange 23 in the middle of the adapter 2. In order to accurately connect the ferrules of the two optical cables, accordingly, Figure 9 As shown, a limiting sleeve 26 is provided at the position of the fixed flange 23 inside the adapter 2, and the cores of the optical cable led from the first interface 21 and the optical cable led from the second interface 22 are docked in the limiting sleeve 26. Docking in the limiting sleeve 26 can improve the accuracy of optical cable docking.

[0106] In order to protect the fiber optic cable core, Figure 9As shown, the limiting sleeve 26 may include a protective sleeve 27 , wherein the material of the protective sleeve 27 is flexible to protect the internal ferrule.

[0107] In order to facilitate the insertion of the optical cable into the adapter 2, accordingly, Figure 9 As shown, the adapter 2 is a split adapter, including a first body portion 2a and a second body portion 2b in an axial direction, and the first body portion 2a and the second body portion 2b are fixed to form the adapter 2.

[0108] The first body portion 2a and the second body portion 2b may be two parts separated along a center plane in the length direction of the adapter 2 .

[0109] Thus, when inserting the optical cable into the adapter 2, the first body portion 2a and the second body portion 2b can be separated, and the optical fiber connector of the optical cable on the left side of the adapter can be placed in the first interface 21 with its ferrule located in the protective cover 27. The optical fiber connector of the optical cable on the right side of the adapter can be placed in the second interface 22 with its ferrule located in the protective cover 27. This can prevent the ferrule of the optical cable from being damaged during the insertion into the adapter 2, thereby protecting the ferrule of the inserted optical cable.

[0110] In order to further improve the docking accuracy of the two optical cables, Figure 10 As shown, a plurality of strip-shaped notches 261 are provided on the wall of the limiting sleeve 26 along the length direction, so that the wall of the limiting sleeve 26 has elasticity.

[0111] Among them, since the adapter 2 is a split adapter, it can be divided into a first main body part 2a and a second main body part 2b along the length direction, so that a part of the limiting sleeve 26 is located on the first main body part 2a, and the other part is located on the second main body part 2b. When the first main body part 2a and the second main body part 2b are fixed together, a limiting sleeve 26 can be formed.

[0112] In one example, because the wall of the limiting sleeve 26 is elastic, the protective sleeve 27 can be interference fit in the limiting sleeve 26. For example, when inserting the protective sleeve 27 into the limiting sleeve 26, the elastic wall of the limiting sleeve 26 can be slightly pried apart to allow the protective sleeve 27 to fit into the limiting sleeve 26. In this way, the protective sleeve 27 can be firmly positioned in the limiting sleeve 26. The protective sleeve 27 is flexible, and although its outer wall is tightly pressed by the elastic wall of the limiting sleeve 26, its inner wall is flexible, which will not damage the ferrule inside. In addition, the stability of the ferrule in the protective sleeve 27 can be improved. Once the stability of the ferrules of the two optical cables in the protective sleeve 27 is improved, the alignment accuracy of the ferrules will also be improved.

[0113] Among them, since a part of the limiting sleeve 26 is located on the first body part 2a and the other part is located on the second body part 2b, when installing the protective sleeve 27 in the limiting sleeve 26, the protective sleeve 27 can be first pressed into the part of the limiting sleeve 26 located on the first body part 2a, or the protective sleeve 27 can be first pressed into the part of the limiting sleeve 26 located on the second body part 2b, such as Figure 9 As shown, the protective cover 27 is located in the portion of the limiting sleeve 26 located in the second body portion 2b.

[0114] In a possible application scenario, when a technician intends to connect two optical cables through the adapter 2, he first disassembles the adapter 2 into the following Figure 9 As shown in the two parts, the protective sleeve 27 is snapped into the limiting sleeve 26 on the first body part 2a, or the limiting sleeve 26 on the second body part 2b. Then, the ferrule of one optical cable is inserted into one end of the protective sleeve 27 through the first interface 21, and the ferrule of the other optical cable is inserted into the other end of the protective sleeve 27 through the second interface 22. In this way, the ferrules of the two optical cables are precisely connected in the protective sleeve 27. Then, the first body part 2a and the second body part 2b are fixed together to form the adapter 2.

[0115] After that, you can attach the adapter 2 to the communication pole and replace it with a fiber optic splitter box after you get the right to use the communication pole. Since the size of the adapter 2 is much smaller than that of the fiber optic splitter box, in order to ensure that the two optical cables connected to the adapter 2 can be connected to the fiber optic splitter box later, sufficient length of the optical cables on both sides of the adapter 2 is reserved to facilitate the subsequent insertion into the fiber optic splitter box. The excess optical cable can be coiled on the adapter 2.

[0116] Among them, in order to ensure that the adapter 2 can be directly replaced with a fiber optic splitter box in the future, the first interface 21 and the second interface 22 of the adapter 2 for connecting the optical cable have the same model and size as the interface of the adapter for connecting the optical cable in the fiber optic splitter box.

[0117] In this embodiment of the present application, during network deployment without obtaining access to the current communication pole, the optical cable leading from the previous communication pole to the current communication pole can be connected to the first interface 21 of adapter 2, and the optical cable leading to the next communication pole can be connected to the second interface 22 of adapter 2. This eliminates the need for technicians to wait until access to the current communication pole is obtained before continuing network deployment, saving network deployment time and shortening the network deployment cycle. Later, after obtaining access to the current communication pole, the optical cable junction box at the current communication pole can be directly replaced with a fiber optic splitter box, simplifying the operation and saving time.

[0118] Moreover, the fiber optic splitter box on the previous communication pole can be connected to the fiber optic splitter box on the next communication pole through adapter 2, so that the connection between the fiber optic splitter box on the previous communication pole and the fiber optic splitter box on the next communication pole will not be affected due to the inability to install the fiber optic splitter box on the current communication pole, thereby not delaying the network use in the residential area where the next communication pole is located.

[0119] The present application also provides an optical cable connection box, which may include: Figures 8 to 10 Adapter 2 shown.

[0120] like Figure 11 And refer to Figure 8 As shown, the optical cable connection box includes a box body 1 and Figures 8 to 10 The adapter 2 shown is fixed to the box body 1 by a fixing flange 23; the box body 1 has a first optical cable port 11 and a second optical cable port 12 on its wall, the first optical cable port 11 being opposite to the first interface 21, and the second optical cable port 12 being opposite to the second interface 22; the optical cable 4 located on one side of the optical cable connection box can pass through the first optical cable port 12 and be inserted into the first interface 21, and the optical cable 4 located on the other side of the optical cable connection box can pass through the second optical cable port 12 and be inserted into the second interface 22.

[0121] The adapter 2 is installed in the box body 1, as shown in FIG. Figure 11 As shown, the box body 1 is an openable structure, that is, the box cover 14 and the box seat 15 are detachably fixed, so that when connecting two optical cables, the box cover 14 can be opened from the box seat 15, and the two optical cables can be respectively inserted into the first interface 21 and the second interface 22 of the adapter 2 located in the box body 1.

[0122] The adapter 2 is located in the box body 1 , and the box body 1 can protect the adapter 2 to extend the service life of the adapter 2 . The adapter 2 is located in the box body 1 , and can also play a further role in dustproof and waterproofing.

[0123] In one example, since the adapter 2 for inserting two optical cables is located in the box body 1, in order to allow the optical cable outside the box body 1 to be inserted into the adapter 2 located inside the box body 1, the box body 1 is correspondingly provided with two optical cable ports, wherein one optical cable port is located opposite to the first interface 21, and the other optical cable port is located opposite to the second interface 22. For example, the two optical cable ports can be respectively denoted as the first optical cable port 11 and the second optical cable port 12, where the first optical cable port 11 is located opposite to the first interface 21, and the second optical cable port 12 is located opposite to the second interface 22.

[0124] The positions of the first optical cable port 11 and the second optical cable port 12 on the box body 1 may have the following situations:

[0125] The first optical cable port 11 and the second optical cable port 12 can both be located on the box cover 14. The first optical cable port 11 and the second optical cable port 12 can also both be located on the box seat 15. Figure 11 And refer to Figure 12 As shown, a portion of the first optical cable port 11 may be located on the box cover 14, and another portion may be located on the box seat 15. When the box cover 14 is snapped onto the box seat 15, the first optical cable port 11 is formed. Similarly, the second optical cable port 12 may also be located partially on the box cover 14, and another portion may be located on the box seat 15. When the box cover 14 is snapped onto the box seat 15, the second optical cable port 12 is formed. The specific locations of the first optical cable port 11 and the second optical cable port 12 are not limited in this embodiment.

[0126] Among them, the adapter 2 is installed in the box body 1, and the first optical cable port 11 and the second optical cable port 12 are used for allowing the optical cable to pass through. For example, the first optical cable port 11 is used for allowing the optical cable located on the left side of the optical cable connection box to pass through, and the second optical cable port 12 is used for allowing the optical cable located on the right side of the optical cable connection box to pass through.

[0127] In one example, both the first optical cable port 11 and the second optical cable port 12 may have flexible pads. The first optical cable port 11 and the second optical cable port 12 are used for passing optical cables. Thus, the flexible pads in the first optical cable port 11 and the second optical cable port 12 can protect the passing optical cables. Furthermore, the flexible pads also act as a seal. The flexible pads fit tightly against the optical cable ports, preventing water and dust from entering the box through the gap between the optical cable and the optical cable ports.

[0128] In one example, the number of first optical cable ports 11 can be one or more, and the number of second optical cable ports 12 can be one or more. For example, the left side of the optical cable connection box has one optical cable and the right side has one optical cable. In this case, the optical cable connection box is used to connect two optical cables, and the number of first optical cable ports 11 and second optical cable ports 12 is one. For another example, the left side of the optical cable connection box has two optical cables and the right side has two optical cables. In this case, the number of first optical cable ports 11 and second optical cable ports 12 is two. Alternatively, if there are two optical cables on both the left and right sides of the optical cable connection box, the number of first optical cable ports 11 and second optical cable ports 12 can also be one, and the first optical cable port 11 and second optical cable port 12 can be large enough to allow two optical cables to pass through.

[0129] In this embodiment, the number of the first optical cable ports 11 and the second optical cable ports 12 is not limited, and one first optical cable port 11 and one second optical cable port 12 may be used as an example.

[0130] In this way, the optical cable on the left side of the optical cable connection box can pass through the first optical cable port 11 on the left box wall and be inserted into the first interface 21 of the adapter 2. The optical cable on the right side of the optical cable connection box can pass through the second optical cable port 12 on the right box wall and be inserted into the second interface 22 of the adapter 2. The optical cables on both sides of the optical cable connection box can be connected through the optical cable connection box.

[0131] As described above, the adapter 2 can be fixed in the box body 1 via the fixing flange 23 , wherein the fixing flange 23 is used to connect the first interface 21 and the second interface 22 on one hand, and to fix the adapter 2 in the box body 1 on the other hand.

[0132] In one example, the fixing flange 23 of the adapter 2 can be fixed in the box body 1 by the cooperation of the protrusion and the groove, for example, Figure 8 As shown, the fixing flange 23 of the adapter 2 has an arc-shaped groove 231 along the circumference of the fixing flange 23, as shown in FIG. Figure 11 As shown, the box body 1 has an arc-shaped protrusion 13 that matches the arc-shaped groove 231. The adapter 2 is fixed in the box body 1 by the arc-shaped protrusion 13 being located in the arc-shaped groove 231. In this way, when the adapter 2 is seated in the box body 1, the arc-shaped protrusion 13 of the box body 1 is stuck in the arc-shaped groove 231 of the fixing flange 23. Then, the box cover 14 is closed on the box seat 15, and the adapter 2 can be pressed into the box body 1.

[0133] For another example, the fixing flange 23 of the adapter 2 has an arc-shaped protrusion, and the box body 1 has an arc-shaped groove that matches the arc-shaped protrusion. When the adapter 2 is seated in the box body 1, the arc-shaped protrusion of the fixing flange 23 is stuck in the arc-shaped groove of the box body 1, and then the box cover 14 is closed on the box seat 15, so that the adapter 2 can be pressed into the box body 1.

[0134] Among them, this embodiment does not limit whether the fixing flange 23 has a groove and the box body 1 has a protrusion, or the fixing flange 23 has a protrusion and the box body 1 has a groove, as long as the fixing flange 23 and the box body 1 can be fixed.

[0135] In one example, the fixing flange 23 of the adapter 2 can also be fixed to the box body 1 in other ways. For example, the fixing flange 23 of the adapter 2 can be installed in the box body 1 by screws. For another example, the fixing flange 23 of the adapter 2 can also be fixed to the box body 1 by welding. This embodiment does not limit the specific fixing method of the adapter 2 and the box body 1, as long as the adapter 2 can be firmly fixed in the box body 1. For ease of understanding, the accompanying drawings can be used as an example in which the fixing flange 23 and the box body 1 are fixed by the matching of the protrusion and the groove, and the fixing flange 23 has a groove and the box body 1 has a protrusion. The following example will take the example of an arc-shaped groove on the fixing flange 23 and an arc-shaped protrusion in the box body 1 as an example to introduce the structure of the arc-shaped groove and the arc-shaped protrusion in detail.

[0136] The arc-shaped groove 231 is a circular groove arranged along the circumferential direction of the fixing flange 23 .

[0137] For example, Figure 8 As shown, the arcuate groove 231 is a complete circumferential groove that extends through the entire circumference of the fixing flange 23. For example, the arcuate groove 231 has an arc of 360 degrees. For another example, the arcuate groove 231 may also be an incomplete circumferential groove. For example, the arcuate groove 231 has an arc of 60 degrees or 120 degrees. This embodiment does not limit the arcuate groove 231, and technicians can flexibly set it according to actual conditions.

[0138] In one example, the arc-shaped protrusion 13 in the box body 1 is adapted to the arc-shaped groove 231 . For example, the thickness of the arc-shaped protrusion 13 is slightly smaller than the groove width of the arc-shaped groove 231 , so that the arc-shaped protrusion 13 can be stuck in the arc-shaped groove 231 .

[0139] In one example, the arcuate protrusion 13 can be located on the box seat 15 of the box body 1, or on the box cover 14 of the box body 1. Alternatively, both the box cover 14 and the box seat 15 have an arcuate protrusion 13, and the arcuate protrusion 13 on the box cover 14 and the arcuate protrusion 13 on the box seat 15 are positioned opposite each other. The fixing flange 23 can have an arcuate groove 231 with an arc of 360 degrees in the circumferential direction. In this way, the fixing flange 23 is located in the box seat 15, and the arcuate protrusion 13 on the box seat 15 is stuck in the arcuate groove 231. When the box cover 14 is closed on the box seat 15, the arcuate protrusion 13 on the box cover 14 is also stuck in the arcuate groove 231, thereby fixing the adapter 2 in the box body 1.

[0140] Among them, this embodiment does not limit whether the arc-shaped protrusion 13 in the box body 1 is located on the box cover 14, on the box seat 15, or whether the arc-shaped protrusion 13 is provided on both the box cover 14 and the box seat 15, as long as it can achieve fixing the adapter 2 in the box body 1.

[0141] In terms of relative position, the adapter 2 can be located in the middle of the box body 1, or the adapter 2 can be located in the box body 1 and close to the end of the box body 1. This embodiment does not limit the specific position of the adapter 2 in the box body 1.

[0142] like Figure 11 As shown, the box cover 14 is opened from the box seat 15, and the box body 1 is in the open state. The optical cable 4 on the left side of the optical cable connection box passes through the first optical cable port 11 located on the box wall of the box body 1 and is plugged into the first interface 21 of the adapter 2. The optical cable 4 on the right side of the optical cable connection box passes through the second optical cable port 12 located on the box wall of the box body 1 and is plugged into the second interface 21 of the adapter 2. Then, the box cover 14 is snapped onto the box seat 15, as shown. Figure 14 As shown, the box body 1 is in a closed state, the optical cable 4 located on the left side of the optical cable connection box extends out of the box body 1 from the first optical cable opening 11, and the optical cable 4 located on the right side of the optical cable connection box extends out of the box body 1 from the second optical cable opening 12.

[0143] In a possible application scenario, when a technician intends to connect two optical cables through the optical cable connection box, he first opens the box cover 14 from the box seat 15, such as Figure 11 As shown, the box body 1 is in the open state. Then, the adapter 2 can be disassembled as follows Figure 9 The two parts shown in the figure, snap the protective sleeve 27 into the limiting sleeve 26 on the first body part 2a, or snap it into the limiting sleeve 26 of the second body part 2b. Afterwards, insert the ferrule of one optical cable from the ferrule channel of the first interface 21 into one end of the protective sleeve 27, and insert the ferrule of another optical cable from the ferrule channel of the second interface 22 into the other end of the protective sleeve 27, so that the ferrules of the two optical cables are precisely docked in the protective sleeve 27. Afterwards, fix the first body part 2a and the second body part 2b together to obtain the adapter 2. Next, fix the adapter 2 with optical cables inserted in both the first interface 21 and the second interface 22 in the box seat 15 through the fixing flange 23, which can be referred to as shown in the figure. Figure 13 Afterwards, the box cover 14 is closed on the box seat 15, and the two optical cables extend out of the box body 1 through the first optical cable port 11 and the second optical cable port 12 respectively. Figure 14 The schematic diagram shown.

[0144] Afterwards, the cable junction box can be attached to the communication pole, and later, after obtaining the right to use the communication pole, it can be replaced with a fiber optic splitter box. Since the size of the cable junction box is much smaller than that of the fiber optic splitter box, in order to ensure that the two optical cables connected to the cable connector can be connected to the fiber optic splitter box later, sufficient length of the optical cables on both sides of the cable junction box is reserved to facilitate their later insertion into the fiber optic splitter box. The excess optical cables can be coiled on the cable junction box.

[0145] Among them, in order to ensure that the optical cable connection box can be directly replaced with an optical fiber distribution box in the future, the first interface 21 and the second interface 22 of the adapter 2 for connecting the optical cable have the same model and size as the interface of the adapter for connecting the optical cable in the optical fiber distribution box.

[0146] In an embodiment of the present application, the optical cable connection box includes a box body and an adapter. In a scenario where the network is being deployed and the right to use the current communication pole has not been obtained, the optical cable leading from the previous communication pole to the current communication pole can be inserted into the adapter, and the optical cable leading to the next communication pole can also be inserted into the adapter. In this way, technicians do not need to wait until they obtain the right to use the current communication pole before continuing with network deployment, which can save network deployment time and shorten the network deployment cycle. After obtaining the right to use the current communication pole at a later time, the optical cable connection box at the current communication pole can be directly replaced with a fiber optic splitter box, which is simple to operate and saves time.

[0147] Moreover, the optical cable connection box can be used to connect the optical fiber splitter box on the previous communication pole and the optical fiber splitter box on the next communication pole, so that the connection between the optical fiber splitter box on the previous communication pole and the optical fiber splitter box on the next communication pole will not be affected due to the inability to install the optical fiber splitter box on the current communication pole, thereby not delaying the network use in the residential area where the next communication pole is located.

[0148] The above description is only one embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
