Technical Field

[0002] The present disclosure relates to the technical field of gateway devices, and in particular to a gateway device and an FTTR networking system. Background Art

[0003] With the development of communication technology, fiber optic transmission is increasingly being used in communication systems, with FTTR (Fiber to the Room) being a crucial component of optical networks. In an FTTR network, the main gateway acts as an ONU (Optical Network Unit) with two fiber optic connectors: one serving as an uplink optical port connected to the optical line terminal (OLT) at the operator's central office to receive the uplink light provided by the OLT, and the other serving as a downlink optical port connected to the optical network terminal (ONT) to provide downlink light to the gateway.

[0004] In the related art, two optical fiber connectors are usually arranged side by side on the backplane of the main gateway, parallel to the backplane. In this arrangement, the two optical fiber connectors occupy a large space, resulting in low space utilization of the main gateway.

[0005] Summary of the Invention

[0006] The present disclosure provides a gateway device and an FTTR networking system, wherein two optical fiber connectors in the gateway device are stacked along the thickness direction of the gateway device to fully utilize the space in the thickness direction of the gateway device, thereby improving the space utilization rate of the gateway device.

[0007] In a first aspect, the present disclosure provides a gateway device, the gateway device comprising a first optical fiber connector and a second optical fiber connector;

[0008] The first optical fiber connector is used to receive optical signals and has a first plug interface;

[0009] The second optical fiber connector is used to transmit an optical signal and has a second plug-in interface;

[0010] The plugging direction of the first plug interface and the plugging direction of the second plug interface both intersect with the thickness direction, and the first optical fiber connector and the second optical fiber connector are stacked along the thickness direction of the gateway device, and the thickness direction is the direction between the panel and the backplane of the gateway device.

[0011] The solution shown in the present disclosure stacks the first optical fiber connector for receiving optical signals and the second optical fiber connector for transmitting optical signals along the thickness direction of the gateway device, thereby improving the space utilization in the thickness direction of the gateway device and saving space in the planar direction, thereby helping to reduce the product size of the gateway device.

[0012] Moreover, the plugging direction of the first plug interface in the first optical fiber connector and the plugging direction of the second plug interface in the second optical fiber connector both intersect with the thickness direction, so that the first optical fiber connector and the second optical fiber connector can be arranged to intersect with the thickness direction, for example, perpendicular to the thickness direction, thereby reducing the dimensional requirements in the thickness direction and further reducing the product size of the gateway device.

[0013] In a possible implementation, the plugging direction of the first plug interface is consistent with the plugging direction of the second plug interface, and in the plugging direction, the end surface of the first plug interface and the end surface of the second plug interface are spaced apart.

[0014] In the solution shown in the present disclosure, most of the structures of the first fiber optic connector and the second fiber optic connector are hidden in the gateway device, and the hidden part usually extends along the plug-in direction of its corresponding fiber optic connector. In this way, by setting the plug-in direction of the first plug interface to be consistent with the plug-in direction of the second plug interface, the respective hidden parts of the first fiber optic connector and the second fiber optic connector can be based on parallel extensions, thereby reducing the space occupied by the first fiber optic connector and the second fiber optic connector in the planar direction, so as to further reduce the product size of the gateway device.

[0015] Moreover, when the plugging directions of the first plug interface and the second plug interface are consistent, by arranging the end face of the first plug interface and the end face of the second plug interface at intervals in the plugging direction, the end face of the first plug interface and the end face of the second plug interface can be staggered by a distance in the plugging direction, so as to ensure that the plugging and unplugging operations of the first plug interface and the plugging and unplugging operations of the second plug interface do not affect each other.

[0016] In a possible implementation, the one of the first and second optical fiber connectors that is farther away from the panel is farther away from the other one of the first and second optical fiber connectors along the plugging direction of the other one of the first and second optical fiber connectors.

[0017] In the solution shown in the present disclosure, when the first fiber optic connector and the second fiber optic connector are stacked along the thickness direction of the gateway device, the one of the first fiber optic connector and the second fiber optic connector that is farther away from the panel is arranged on the outside, and the other is arranged on the inside. Therefore, by arranging the outer fiber optic connector away from the inner fiber optic connector along the plugging and unplugging direction of the inner fiber optic connector, the inner fiber optic connector can be avoided and exposed to facilitate the plugging and unplugging operations on the inner fiber optic connector.

[0018] In a possible implementation, the second optical fiber connector is farther away from the panel than the first optical fiber connector.

[0019] In the solution shown in the present disclosure, the second optical fiber connector for transmitting optical signals has a higher plugging and unplugging frequency than the first optical fiber connector for receiving optical signals. Therefore, by placing the second optical fiber connector on a side farther away from the panel, the second optical fiber connector can be set on the outside of the first optical fiber connector for easy plugging and unplugging.

[0020] In a possible implementation, the back plate is recessed toward the panel to form a first accommodating groove, one sidewall of the first accommodating groove has a stepped structure, the stepped structure includes a first side surface, a stepped surface, and a second side surface connected in sequence, the first side surface has a first opening, the second side surface has a second opening, and the first side surface and the second side surface are arranged along the thickness direction;

[0021] The first optical fiber connector and the second optical fiber connector are accommodated in a accommodating cavity formed by the panel and the backplane, wherein the first plug interface is exposed to the backplane through the first opening, and the second plug interface is exposed to the backplane through the second opening, and the first accommodating groove is used to accommodate the connectors of the optical fibers respectively adapted to the first optical fiber connector and the second optical fiber connector.

[0022] In the solution shown in the present disclosure, the first fiber optic connector and the second fiber optic connector are exposed through different sides of the step structure, so that the first fiber optic connector and the second fiber optic connector can be separated by the step surface between the two sides, avoiding interference between the plugging and unplugging operations therebetween.

[0023] In a possible implementation, the gateway device further includes at least one additional socket, and a plugging direction of the at least one additional socket intersects with the thickness direction;

[0024] The back plate is recessed in a direction close to the front panel to form a second receiving groove, wherein the second receiving groove is used to receive a connector adapted to the additional socket.

[0025] The solution disclosed herein reduces the planar space occupied by the additional socket by setting the insertion direction to intersect with the thickness direction, for example, perpendicular to the thickness direction, thereby helping to reduce the product size of the gateway device. It also prevents the connector adapted by the additional socket from protruding excessively from the backplate, thereby affecting the wall-mounting installation of the gateway device. By providing a second receiving slot for accommodating the connector adapted by the additional socket, it is possible to prevent the connector adapted by the additional socket from protruding beyond the peripheral edge of the backplate, for example, the bottom edge, thereby affecting the vertical installation of the gateway device using the support legs.

[0026] In one possible implementation, the back panel is recessed toward the panel to form a fiber winding groove, the fiber winding groove is connected to the first accommodating groove, the fiber winding groove surrounds the outside of the second accommodating groove, and is arranged along the circumferential edge of the back panel, wherein the fiber winding groove is used to accommodate the optical fiber cable.

[0027] The solution shown in the present disclosure fixes the position of the cable in the optical fiber connected to the first optical fiber connector and the second optical fiber connector through the fiber winding groove, so that the cables can be bundled to improve the aesthetics of the gateway device; and the fiber winding groove is surrounded by the outer side of the second accommodating groove and arranged along the circumferential edge of the backplane, thereby expanding the extension length of the fiber winding groove.

[0028] In a possible implementation, when the backplane is recessed to form the first accommodating groove, the second accommodating groove, and the fiber coil groove, the recessed depths of the backplane decrease sequentially.

[0029] The solution shown in the present disclosure sets the recess depths of the first accommodating groove, the second accommodating groove and the fiber coil groove differently. While meeting the respective groove body depth requirements of the first accommodating groove, the second accommodating groove and the fiber coil groove, the internal space of the gateway device can be maximized to place more electronic components in the accommodating cavity formed by the panel and the back panel.

[0030] In a second aspect, the present disclosure provides an FTTR networking system, which includes the gateway device of the first aspect.

[0031] In the solution shown in the present disclosure, the first optical fiber connector for receiving optical signals and the second optical fiber connector for transmitting optical signals in the gateway device are stacked along the thickness direction of the gateway device, so that the space in the thickness direction of the gateway device can be fully utilized, the space utilization rate of the gateway device is improved, the space in the plane direction is saved, and it helps to reduce the product size of the gateway device.

[0032] Moreover, the plugging direction of the first plug interface in the first optical fiber connector and the plugging direction of the second plug interface in the second optical fiber connector both intersect with the thickness direction, so that the first optical fiber connector and the second optical fiber connector can be arranged to intersect with the thickness direction, for example, perpendicular to the thickness direction, thereby reducing the dimensional requirements in the thickness direction and further reducing the product size of the gateway device.

[0041] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0042] This embodiment relates to a gateway device in which a first optical fiber connector for receiving optical signals and a second optical fiber connector for transmitting optical signals are stacked along the thickness of the gateway device. This fully utilizes the space along the thickness of the gateway device, thereby improving the space utilization of the gateway device, saving space in the planar direction, and thus helping to reduce the product size of the gateway device. For ease of understanding, the structure of the gateway device can be illustrated as a master gateway in an FTTR networking system.

[0043] The arrangement of the first optical fiber connector and the second optical fiber connector in the gateway device will be described below.

[0044] Figures 1, 4, 5 and 6 are schematic diagrams of the structure of the gateway device from different perspectives, Figure 2 is a partial exploded view of the gateway device, and Figure 3 is a schematic diagram of the structure of the gateway device in cooperation with the optical fiber. As shown in Figures 1 and 2, the gateway device includes a first optical fiber connector 1, a second optical fiber connector 2, a panel 3 and a back panel 4. The panel 3 and the back panel 4 can be assembled together to form a accommodating cavity, and the first optical fiber connector 1 and the second optical fiber connector 2 can be accommodated in the accommodating cavity. In one example, the panel 3 and the back panel 4 can be snap-connected. During specific use, the panel 3 in the gateway device can face the user, and the back panel 4 arranged opposite to the panel 3 can be hidden behind the panel 3 so as to be invisible to the user.

[0045] The first optical fiber connector 1 and the second optical fiber connector 2 can be arranged on a side close to the backplane 4. The first optical fiber connector 1 has a first plug port 11, and the first plug port 11 can be exposed relative to the backplane 4, so that an external optical fiber can be connected to the first optical fiber connector 1 through the first plug port 11. Similarly, the second optical fiber connector 2 has a second plug port 21, and the second plug port 21 can be exposed relative to the backplane 4, so that an external optical fiber can be connected to the second optical fiber connector 2 through the second plug port 21.

[0046] The first optical fiber connector 1 can serve as an optical signal input port for receiving optical signals, and the second optical fiber connector 2 can serve as an optical signal output port for transmitting optical signals. The optical signal input and output ports of a gateway device can also be referred to as optical ports, with the optical signal input port being referred to as an uplink optical port and the optical signal output port being referred to as a downlink optical port.

[0047] As shown in Figures 1 and 3, the first fiber optic connector 1 and the second fiber optic connector 2 are stacked along the thickness direction T of the gateway device, wherein the thickness direction T is the direction between the panel 3 and the back panel 4 of the gateway device. In one example, when the gateway device is placed horizontally or wall-mounted, for example, when the back panel 4 is used as a loading surface to be placed on a desktop as a fixed carrier or connected to a wall as a fixed carrier, the thickness direction is perpendicular to the back panel 4 as the loading surface. In another example, when the gateway device is placed vertically, for example, when the bottom of the gateway device has supporting feet, and the gateway device is supported on the desktop by the supporting feet, the connection surface between the supporting feet and the desktop can be used as the loading surface. In this case, the thickness direction can be parallel to the loading surface. A fixed carrier such as a desktop or a wall is used to carry the gateway device.

[0048] In this embodiment, "overlapping" can be understood as the first optical fiber connector 1 and the second optical fiber connector 2 at least partially overlapping in the thickness direction T of the gateway device. In other words, the orthographic projection of the first optical fiber connector 1 on a set plane can at least partially overlap with the orthographic projection of the second optical fiber connector 2 on the set plane, and the set plane is perpendicular to the thickness direction T. The set plane can be, for example, the plane where the backplane 4 is located.

[0049] In one example, the orthographic projection of the first optical fiber connector 1 on the set plane and the orthographic projection of the second optical fiber connector 2 on the set plane may completely overlap. In another example, the orthographic projection of the first optical fiber connector 1 on the set plane and the orthographic projection of the second optical fiber connector 2 on the set plane may only partially overlap, that is, the second optical fiber connector 2 may be offset relative to the first optical fiber connector 1 in a direction perpendicular to the thickness direction T (for example, within the set plane). Exemplarily, the second optical fiber connector 2 may be offset relative to the first optical fiber connector 1 in a direction closer to the top or bottom of the backplane 4; alternatively, the second optical fiber connector 2 may be offset relative to the first optical fiber connector 1 in a direction closer to one of the sides of the backplane 4.

[0050] As shown in Figure 2, the first fiber optic connector 1 and the second fiber optic connector 2 are connected to an internal optical fiber on one side of the accommodating cavity, so that after the connectors of the optical fibers adapted by the first fiber optic connector 1 and the second fiber optic connector 2 are inserted into the first plug interface 11 and the second plug interface 21, the connectors of the external optical fibers can be docked with the connectors of their corresponding internal optical fibers to realize the functions of receiving and sending optical signals.

[0051] As shown in Figures 1 and 3, the plugging direction L1 of the first plug port 11 and the plugging direction L2 of the second plug port 21 both intersect with the thickness direction T. In one example, the plugging direction L1 of the first plug port 11 and the plugging direction L2 of the second plug port 21 are both perpendicular to the thickness direction T. In this way, the first and second fiber optic connectors 1 and 2, which are larger in size due to connecting the internal optical fibers, can be arranged substantially parallel to the front panel 3 and back panel 4 in a planar space, thereby reducing the space requirement in the thickness direction of the gateway device.

[0052] As shown in Figures 1, 2, and 3, the plugging direction L1 of the first plug port 11 can be aligned with the plugging direction L2 of the second plug port 21. In one example, the first and second plug ports 11, 21 can be oriented toward the bottom edge of the gateway device. During use, external optical fibers can be inserted into the first and second plug ports 11, 21 from the bottom to the top of the gateway device.

[0053] As shown in Figure 1, when the first optical fiber connector 1 and the second optical fiber connector 2 are stacked along the thickness of the gateway device, one of the first optical fiber connector 1 and the second optical fiber connector 2 is closer to the outside of the gateway device, while the other is closer to the inside of the gateway device. Furthermore, because the first optical fiber connector 1 and the second optical fiber connector 2 are positioned near the backplane 4, the optical fiber connector closer to the outside of the gateway device is further away from the panel 3 than the other. The outer connector may obstruct the insertion and removal of the inner connector.

[0054] In this regard, when the plug-in direction L1 of the first plug-in interface 11 is consistent with the plug-in direction L2 of the second plug-in interface 21, as shown in Figures 1 and 3, in this plug-in direction, the end face of the first plug-in interface 11 and the end face of the second plug-in interface 21 are arranged with an interval. That is, the first optical fiber connector 1 (or the second optical fiber connector 2) can be offset by a distance D relative to the second optical fiber connector 2 (or the first optical fiber connector 1) along the plug-in direction, so that the end face of the first plug-in interface 11 and the end face of the second plug-in interface 21 are staggered. In this case, when the external optical fiber adapted to the first optical fiber connector 1 and the external optical fiber adapted to the second optical fiber connector 2 are inserted into the corresponding plug-in interfaces, the depths of the two external optical fibers are different.

[0055] In specific applications, as shown in FIG3 , since the end faces of the first plug interface 11 and the end faces of the second plug interface 21 are staggered and arranged at intervals in the plugging direction, the connectors of the two external optical fibers respectively inserted into the first plug interface 11 and the second plug interface 21 avoid each other, so that the user's fingers can conveniently pinch one of the connectors for plugging and unplugging without interfering with the other connector.

[0056] In this embodiment, the first and second optical fiber connectors 1 and 2 may employ substantially the same structure. However, due to their different functions, users may operate the first and second optical fiber connectors 1 and 2 at different frequencies. Typically, users do not frequently plug or unplug the first optical fiber connector 1, which receives optical signals; whereas, users frequently plug or unplug the second optical fiber connector 2, which transmits optical signals. In this case, as shown in Figures 1, 3, and 4, the second optical fiber connector 2, which has a higher plugging and unplugging frequency, can be positioned outside the first optical fiber connector 1, which has a lower plugging and unplugging frequency. In other words, the second optical fiber connector 2 is further away from the panel 3 than the first optical fiber connector 1.

[0057] Furthermore, as shown in Figures 1, 3, and 4, the second optical fiber connector 2 located on the outside can be moved away from the first optical fiber connector 1 along the plugging direction L1 of the first optical fiber connector 1 located on the inside, so that the first plugging port 11 of the first optical fiber connector 1 can be exposed without being obscured by the second optical fiber connector 2. In other words, in the gateway device, the one of the first optical fiber connector 1 and the second optical fiber connector 2 that is farther away from the panel 3 can be moved away from the other one along the plugging direction of the first optical fiber connector 1 and the second optical fiber connector 2, so that the outer optical fiber connector can avoid the inner optical fiber connector.

[0058] The following describes the structure of the backplane in the gateway device.

[0059] As shown in Figures 1 and 2, the back panel 4 can be recessed toward the front panel 3 to form a first receiving groove 41. This first receiving groove 41 can serve as a finger-safe groove. When a user inserts or removes the optical fibers adapted by the first and second optical fiber connectors 1 and 2, they can insert their fingers into this first receiving groove 41 to grasp the optical fiber connector. In other words, this first receiving groove 41 can be used to accommodate the connectors of the optical fibers adapted by the first and second optical fiber connectors 1 and 2, respectively.

[0060] One sidewall of the first receiving slot 41 may have a stepped structure, comprising a first side surface 411, a stepped surface 412, and a second side surface 413, which are sequentially connected. The first side surface 411 defines a first opening 4111, and the second side surface 413 defines a second opening 4131. The first side surface 411 and the second side surface 413 are arranged along the thickness direction T. The first plug port 11 is exposed to the back panel 4 through the first opening 4111, and the second plug port 21 is exposed to the back panel 4 through the second opening 4131.

[0061] In one example, the first plug interface 11 of the first optical fiber connector 1 and the second plug interface 21 of the second optical fiber connector 2 can both face the bottom of the gateway device, and the first accommodating groove 41 is formed between the bottom edge of the back panel 4 and the exposed sides of the first plug interface 11 and the second plug interface 21, so that the step structure can be formed on the side of the first accommodating groove 41 away from the bottom edge of the back panel 4.

[0062] As shown in Figures 1 and 2, in the stepped structure, the first side surface 411 and the second side surface 413 may be substantially parallel to the thickness direction T of the gateway device, and the stepped surface 412 connected between the first side surface 411 and the second side surface 413 may be arranged substantially perpendicular to the thickness direction T. The first side surface 411 and the second side surface 413 are separated by the stepped surface 412, so that the first side surface 411 and the second side surface 413 can be staggered along the plugging direction of the first plug interface 11 and the second plug interface 21. In one example, the first side surface 411 can be located on the side of the second side surface 413 close to the bottom edge of the back panel 4, so that in the first receiving groove 41, the size of the portion where the first side surface 411 is located can be smaller than the size of the portion where the second side surface 413 is located.

[0063] As shown in Figures 5 and 6, the back panel 4 can also be recessed toward the front panel 3 to form a fiber winding groove 43. This fiber winding groove 43 is connected to the first receiving groove 41 and is used to accommodate optical fiber cables. In specific applications, after a portion of the external optical fiber is inserted into the first plug-in port 11 (or the second plug-in port 21) to achieve a connection between the external optical fiber and the first optical fiber connector 1 (or the second optical fiber connector 2), the larger connector portion of the external optical fiber can be accommodated in the first receiving groove 41, while the cable portion connected to the connector can be bundled in the fiber winding groove 43.

[0064] In one example, as shown in Figures 5 and 6 , the gateway device may further include at least one cable retaining structure 44 , which may be connected to a sidewall of the fiber winding trough 43 to restrict the position of the optical fiber cables in the thickness direction. In a specific application, the optical fiber cables may be retained between the bottom wall and two sidewalls of the fiber winding trough 43 , as well as a portion of the cable retaining structure opposite the bottom wall of the fiber winding trough 43 .

[0065] In one example, the orthographic projection of the wire-gripping structure on a set plane perpendicular to the thickness direction may partially overlap with the orthographic projection of the fiber tray groove 43 on the set plane.

[0066] As shown in Figures 4 and 5, the gateway device also includes at least one additional socket 5. Exemplarily, the additional socket 5 can be either a network cable socket or a power cord socket. The plugging direction L3 of the at least one additional socket 5 can intersect with the thickness direction T of the gateway device. In one example, the plugging direction L3 of the additional socket 5 can be perpendicular to the thickness direction T, and the plugging direction L3 of the additional socket 5 can be consistent with the plugging direction of the first socket 11 and the second socket 21, for example, both facing the bottom edge of the backplane 4.

[0067] The back panel 4 is further recessed toward the front panel 3 to form a second receiving groove 42, wherein the second receiving groove 42 is used to accommodate a connector adapted for the additional socket 5. As shown in FIG5 , the fiber winding groove 43 can be arranged along the circumferential edge of the back panel 4, and the second receiving groove 42 can be located within the annular space enclosed by the fiber winding groove 43. In other words, the fiber winding groove 43 can surround the outside of the second receiving groove 42 to maximize the extension length of the fiber winding groove 43.

[0068] In one example, the first accommodating groove 41, the second accommodating groove 42, and the fiber winding groove 43 have different depths along the thickness direction. As shown in Figures 6 and 7, where Figure 7 is an enlarged view of portion A in Figure 6, the depth of the first accommodating groove 41 can be greater than the depth of the second accommodating groove 42, and the depth of the second accommodating groove 42 can be greater than the depth of the fiber winding groove 43. As a result, when the back panel 4 is recessed to form the first accommodating groove 41, the second accommodating groove 42, and the fiber winding groove 43, the depth of the recessed back panel 4 decreases sequentially. In this embodiment, the specific depths of the first accommodating groove 41, the second accommodating groove 42, and the fiber winding groove 43 can be set as needed.

[0069] In one example, in addition to the first fiber optic connector 1 and the second fiber optic connector 2, the accommodating cavity formed by the backplane 4 and the front panel 3 can also accommodate a variety of electronic components to meet the functional requirements of the gateway device. The shapes of the first accommodating groove 41, the second accommodating groove 42, and the fiber winding groove 43 formed in the recesses of the backplane 4 can affect the shape of the accommodating cavity.

[0070] In an embodiment of the present disclosure, a first optical fiber connector for receiving optical signals and a second optical fiber connector for transmitting optical signals in a gateway device are stacked along the thickness direction of the gateway device, thereby making full use of the space in the thickness direction of the gateway device, improving the space utilization of the gateway device, saving space in the plane direction, and helping to reduce the product size of the gateway device.

[0071] Moreover, the plugging direction of the first plug interface in the first optical fiber connector and the plugging direction of the second plug interface in the second optical fiber connector both intersect with the thickness direction, so that the first optical fiber connector and the second optical fiber connector can be arranged to intersect with the thickness direction, for example, perpendicular to the thickness direction, thereby reducing the dimensional requirements in the thickness direction and further reducing the product size of the gateway device.

[0072] The embodiment of the present disclosure also provides an FTTR networking system, which includes the above gateway device.

[0073] In one example, the networking system includes a master gateway and a slave gateway in communication connection, where the master gateway can be a gateway device as described above. In this case, a first optical fiber connector 1 for receiving optical signals in the master gateway can be connected to an OLT arranged in a computer room via an optical fiber, while a second optical fiber connector 2 for transmitting optical signals can be connected to a slave gateway arranged in a room via an optical fiber.

[0074] In one example, the networking system may further include an optical splitter, which is connected between the master gateway and the slave gateway via an optical fiber to implement a configuration network in which a single master gateway controls multiple slave gateways. In this case, the first optical fiber connector 1 for receiving optical signals in the optical splitter can be connected to the master gateway via an optical fiber, and the second optical fiber connector 2 for transmitting optical signals can be connected to the slave gateway arranged in the room via an optical fiber. The optical splitter can be provided with multiple second optical fiber connectors 2 for transmitting optical signals, and the first optical fiber connector 1 can be stacked with any one of the second optical fiber connectors 2 along the thickness direction of the optical splitter to fully utilize the space in the thickness direction.
