Description

Technical Field

[0001] This application relates to the field of optical fiber communication technology, and in particular to an optical communication device and an optical fiber communication system. Background Technology

[0002] Optical communication network equipment, such as switches, can expand network connectivity by providing multiple ports to connect multiple terminal devices. Switches themselves do not directly support fiber optic connections; therefore, optical modules need to be installed within the switch to enable interfacing with fiber optics. An optical module is a conversion module that connects fiber optics to electronic devices, such as those in a switch. It converts optical signals in the fiber optic cable into electrical signals that the switch can process, or it converts electrical signals from the switch into optical signals for transmission over the fiber optic cable.

[0003] Small switches, such as the Type 86 panel switch, are typically used in hospitals, small offices, homes, and schools where a small number of terminal interfaces and short network distances are required. The Type 86 panel switch refers to a type of small switch with dimensions of 86 mm in both length and width, resembling a panel for household switches, sockets, or data outlets.

[0004] However, due to the size limitations of small switches, they cannot be compatible with optical modules of various sizes. Summary of the Invention

The intermediate adapter is disposed between the top cover and the bottom cover to divide the accommodating space into a first accommodating space and a second accommodating space adjacent to each other along the second direction. The optical module, the first circuit board, the heat sink, and the second circuit board are all disposed in the first accommodating space. The intermediate adapter has an opening, and the connector extends out of the opening from the first accommodating space and is disposed in the second accommodating space.

[0045] The switch in the related technology includes a rectangular housing and an optical module. The rectangular housing includes two side walls opposite each other along the x-axis and two side walls opposite each other along the y-axis. When the optical module is installed in the rectangular housing, the length direction of the optical module is parallel to the x-axis or the length direction of the optical module is parallel to the y-axis. This makes the plug interface of the optical module face one of the four side walls of the rectangular housing, which facilitates the connection of the optical cable to the plug interface.

[0046] However, for the Type 86 panel switch, which is 86 mm in both length and width, optical modules longer than 86 mm cannot be adapted to the Type 86 panel switch, thus limiting the design of small switches.

[0047] Therefore, this application provides an optical communication device, which can be a switch. When the optical module is placed in a rectangular housing, the length direction of the optical module intersects the x-axis or the length direction of the optical module intersects the y-axis. In other words, the optical module is placed obliquely in the rectangular housing, which solves the problem that optical modules of various sizes cannot be adapted to small switches. Larger optical modules can be installed without increasing the size of the rectangular housing.

[0048] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0049] In this embodiment of the application, the first direction is the x-axis shown in the figure, and the second direction is the z-axis shown in the figure; the first direction is perpendicular to the second direction.

[0050] refer to Figure 1 and Figure 2 The optical communication device provided in this application embodiment includes: a rectangular housing 100, the rectangular housing 100 including a first sidewall 1011 and a second sidewall 1012, the first sidewall 1011 and the second sidewall 1012 being opposite each other along a first direction (x-axis shown in the figure).

[0051] The optical communication equipment also includes: an optical module 200, which is disposed in a rectangular housing 100; the optical module 200 has a plug interface 201, to which an optical cable is plugged, and the plugging direction of the optical cable has a first angle with a first direction (x-axis shown in the figure), the first angle being greater than 0° and less than 90°.

[0052] The insertion direction of the optical cable is the same as the length direction of the optical module 200. The insertion direction of the optical cable has a first angle with the first direction (x-axis shown in the figure), indicating that the optical module 200 is placed obliquely in the rectangular housing 100, which solves the problem that optical modules 200 of various sizes cannot be adapted to small optical communication equipment. Larger optical modules 200 can be installed without increasing the size of the rectangular housing 100.

[0053] It should be noted that the rectangular housing 100 also includes a third sidewall, the two ends of which intersect with the first sidewall 1011 and the second sidewall 1012 respectively. The first sidewall 1011 is provided with a clearance opening, or the third sidewall is provided with a clearance opening, or a clearance opening is provided at the intersection of the first sidewall 1011 and the third sidewall. When the optical module 200 is placed obliquely in the rectangular housing 100, the insertion interface 201 of the optical module 200 can be connected to the optical cable through the clearance opening.

[0054] When the first included angle is greater than 0° and less than 45°, an avoidance opening is provided on the first side wall 1011; when the first included angle is greater than 45° and less than 90°, an avoidance opening is provided on the third side wall; when the first included angle is equal to 45°, an avoidance opening is provided at the intersection of the first side wall 1011 and the third side wall.

[0055] In this embodiment, when the first included angle is 45°, the optical module 200 is located on the diagonal of the rectangular housing 100. This area has the largest spatial size and can accommodate optical modules 200 of various sizes.

[0056] refer to Figure 3In this embodiment of the application, the optical communication device further includes: a first circuit board 301 and a second circuit board 302, both of which are disposed in the rectangular housing 100; the first circuit board 301 is a motherboard, used for the management and control of the optical communication device and the protocol processing of data, and is responsible for processing various communication protocols; the second circuit board 302 is a backplane, used for connecting the engine, switching matrix, line card, fan, power supply, etc.

[0057] A first connector is provided on the first circuit board 301, and a second connector that matches the first connector is provided on the second circuit board 302. The first connector and the second connector are connected, so that the first circuit board 301 and the second circuit board 302 are electrically connected.

[0058] The optical communication equipment also includes a heat sink 303, which is disposed in the rectangular housing 100. Along the second direction (the z-axis shown in the figure), the optical module 200, the first circuit board 301, the heat sink 303, and the second circuit board 302 are stacked in sequence. That is, the heat sink 303 is located between the first circuit board 301 and the second circuit board 302, and can dissipate heat from both the first circuit board 301 and the second circuit board 302 at the same time. This effectively solves the heat dissipation problem of the circuit board and makes the overall structure of the optical communication equipment more compact, further reducing the size of the optical communication equipment.

[0059] Along the second direction (z-axis shown in the figure), the heat sink 303 has a front and a back. The front has a first limiting socket, a first circuit board 301 is disposed on the front, and a first limiting member of the first circuit board 301 is connected to the first limiting socket. The back has a second limiting socket, a second circuit board 302 is disposed on the back, and a second limiting member of the second circuit board 302 is connected to the second limiting socket.

[0060] During assembly, the first circuit board 301 is first placed on the front of the heat sink 303, so that the first limiting member is connected to the first limiting socket; the second circuit board 302 is placed on the back, so that the second limiting member is connected to the second limiting socket; then the first connector and the second connector are connected.

[0061] In other words, the heat sink 303 can serve as a connection reference for the first circuit board 301 and the second circuit board 302. The heat sink 303 is used to limit the first circuit board 301 and the second circuit board 302 before connecting the first connector and the second connector, so that the first circuit board 301 and the second circuit board 302 are electrically connected. This reduces assembly difficulty, improves installation efficiency, and avoids damage to the first connector and the second connector due to inaccurate insertion.

[0062] The fusion splice box is used to encapsulate the optical cable plugged into the optical module 200. In related technologies, the fusion splice box is usually set up separately. When the optical communication equipment is wall-mounted, the fusion splice box also needs to occupy some wall space, resulting in a complex layout. Moreover, when the optical cable is led out from the optical communication equipment and encapsulated in the fusion splice box, it will result in messy wiring, which will affect the aesthetics and increase the difficulty of later maintenance.

[0063] To solve the above-mentioned technical problems, the optical communication device in this application embodiment also has the function of encapsulating optical cables, as shown in the reference. Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment of the application, the rectangular shell 100 may include: a bottom shell 101, an intermediate adapter 102, and a top cover 103. The top cover 103 and the bottom shell 101 are connected to form an accommodating space. The intermediate adapter 102 is disposed between the top cover 103 and the bottom shell 101 to divide the accommodating space into a first accommodating space 104 and a second accommodating space 105 that are adjacent to each other and disposed vertically along the second direction (z-axis shown in the figure). The space between the intermediate adapter 102 and the top cover 103 is the second accommodating space 105, and the space between the bottom shell 101 and the intermediate adapter 102 is the first accommodating space 104.

[0064] The optical module 200, the first circuit board 301, the heat sink 303, and the second circuit board 302 are all disposed in the first receiving space. An intermediate adapter 102 has a recessed area that faces into the first receiving space 104. The first inner wall 1026 of the recess is parallel to the second direction (the z-axis shown in the figure). An opening is provided on the first inner wall 1026 to connect the first receiving space 104 and the second receiving space 105. The connector 201 of the optical module 200 extends out of the opening from the first receiving space 104 and is disposed in the second receiving space 105. The optical cable connected to the connector 201 is also disposed in the second receiving space 105, thereby achieving the encapsulation of the optical cable.

[0065] In related technologies, the optical cable connected to the plug interface 201 is led out and housed in the fusion splice box; in this embodiment, the intermediate adapter 102 and the top cover 103 together form the fusion splice box 500; by integrating the fusion splice box 500 into the optical communication equipment, the optical cable plugged into the optical module 200 is directly encapsulated in the optical communication equipment, simplifying wiring and avoiding the fusion splice box occupying extra wall space.

[0066] Continue to refer to Figure 4In this embodiment, the intermediate adapter 102 has a first surface, on which a cable receiving groove 1021 is provided. The cable winding inlet 1024 of the cable receiving groove 1021 is close to the plug interface 201 of the optical module 200. The optical cable plugged into the optical module 200 is placed in the cable receiving groove 1021 from the cable winding inlet 1024 so that the optical cable is neatly fixed in the second receiving space 105 and the optical cable is prevented from getting tangled.

[0067] The first surface is also provided with multiple clips 1023, which are distributed in the slot of the cable receiving groove 1021. When the optical cable is placed in the cable receiving groove 1021, the clips 1023 can restrict the optical cable in the cable receiving groove 1021 and prevent the optical cable from coming out of the cable receiving groove 1021.

[0068] It should be noted that the cable receiving groove 1021 can be an annular groove arranged circumferentially along the first surface.

[0069] refer to Figure 4 and Figure 5 In this embodiment, the intermediate adapter 102 also has an arc-shaped guide plate 1022. A recess is formed on the intermediate adapter 102 that is recessed into the first receiving space 104. The second inner wall surface 1027 of the recess is perpendicular to the first inner wall surface 1026, that is, the second inner wall surface 1027 is the bottom surface of the recess. The arc-shaped guide plate 1022 is vertically disposed on the second inner wall surface 1027. The arc-shaped guide plate 1022 includes a first end and a second end. The first end is close to the plug interface 201, and the second end is close to the cable winding inlet 1024. The arc-shaped guide plate 1022 is used to guide the optical cable extending from the plug interface 201 through the cable winding inlet 1024 into the cable receiving groove 1021.

[0070] The arc-shaped guide plate 1022 can increase the bending angle of the optical cable at the plug interface 201, avoid excessive bending of the optical cable at the plug interface 201, and prevent the optical cable from breaking.

[0071] The second accommodating space 105 has a third inner wall surface 1028. An arc-shaped guide plate 1022 is close to the third inner wall surface 1028 and is spaced apart from the third inner wall surface 1028 along the first direction (x-axis shown in the figure). That is, there is a gap between the arc-shaped guide plate 1022 and the third inner wall surface 1028 to form a fastening groove 1025 between the arc-shaped guide plate 1022 and the third inner wall surface 1028.

[0072] When the optical cable extending from the connector 201 is attached to the arc-shaped guide plate 1022 and enters the cable receiving groove 1021, the fastening groove 1025 can clamp the optical cable to prevent the optical cable from detaching from the arc-shaped guide plate 1022.

[0073] refer toFigure 7 , Figure 8 and Figure 9 In this embodiment of the application, the intermediate adapter 102 has a first surface and the upper cover 103 has a second surface. Both the first surface and the second surface are disposed in the second accommodating space 105, and the first surface and the second surface are opposite to each other along the second direction (z-axis shown in the figure).

[0074] In one embodiment, a cable receiving groove 1021 is provided on the first surface. The optical cable plugged into the optical module 200 is placed in the cable receiving groove 1021 from the cable winding inlet 1024, so that the optical cable is neatly arranged in the second receiving space 105, avoiding the optical cable from being tangled and knotted, and improving the efficiency of later maintenance.

[0075] In another embodiment, a cable fixing member is provided on the second surface. The optical cable plugged into the optical module 200 is fixed on the second surface through the cable fixing member, so that the optical cable is neatly arranged in the second receiving space 105, avoiding the optical cable from being tangled and knotted, and improving the efficiency of later maintenance.

[0076] In another embodiment, a cable receiving groove 1021 is provided on the first surface, and a cable fixing member is provided on the second surface; after the optical cable inserted into the optical module 200 is placed in the cable receiving groove 1021 from the cable winding inlet 1024, the remaining optical cable will be placed on the second surface through the cable fixing member; so that the optical cable is neatly arranged in the second receiving space, avoiding the optical cable from being haphazardly tangled and knotted, and improving the efficiency of later maintenance.

[0077] The cable fastener may include multiple protruding components 131, which are distributed at equal circumferential intervals along the second surface; for example... Figure 9 As shown, the dashed line indicates that the optical cable is wrapped around the perimeter of the multiple protruding components 131.

[0078] The protrusion component 131 may include a hollow cylinder 1031 and a first limiting block 1032. The hollow cylinder 1031 and the first limiting block 1032 are spaced apart. The optical cable is embedded between the hollow cylinder 1031 and the first limiting block 1032 while surrounding the hollow cylinder 1031. The hollow cylinder 1031 can prevent the optical cable from bending excessively, and the first limiting block 1032 can fix the optical cable and prevent the optical cable from detaching from the hollow cylinder 1031.

[0079] The protrusion component 131 may also include an arc-shaped protrusion 1033 and a second limiting block 1034. The arc-shaped protrusion 1033 and the second limiting block 1034 are spaced apart. The optical cable surrounds the arc-shaped protrusion 1033 and is embedded between the arc-shaped protrusion 1033 and the second limiting block 1034. The arc-shaped protrusion 1033 can prevent the optical cable from bending excessively, and the second limiting block 1034 can fix the optical cable and prevent the optical cable from detaching from the arc-shaped protrusion 1033.

[0080] In practical applications, the demand for small optical communication equipment is increasing. For example, in hospital clinics, 86-type panel optical communication equipment is usually wall-mounted. When it is necessary to expand the network connection, it is necessary to re-run high-voltage power and deploy optical fibers, which is slow and costly. It also causes messy wiring on site. Moreover, once the optical fiber is laid, it is very difficult to inspect and replace, resulting in high maintenance costs.

[0081] To address the aforementioned technical problems, the optical communication device in this application embodiment also has a rapid cascading deployment function; see reference Figure 1 In this embodiment of the application, the optical communication device may further include: a connection interface, which is used to connect to an external power supply device, connect to an external device to be charged, and transmit data signals.

[0082] In other words, the connection interface can be a Type-C interface 401. The Type-C interface 401 can accept power from an external power supply device and can also charge other optical communication devices. While charging other optical communication devices, it can also transmit data signals to other optical communication devices. When it is necessary to expand the network connection, simply interconnect the Type-C interfaces 401 of the optical communication devices to enable multiple optical communication devices to be cascaded and deployed, thereby expanding the network.

[0083] It should be noted that, as Figure 6 As shown, the optical communication device may further include: a first connection terminal 402 and a second connection terminal 403, wherein the first connection terminal 402 is used to connect to network equipment and the second connection terminal 403 is used to connect to an external adapter.

[0084] refer to Figure 10 and Figure 11 The optical communication device includes a first diode, a second diode, a third diode, and a fourth diode. After the external adapter supplies power to the optical communication device through the second connection terminal 403, the electrical signal is transmitted to the first circuit board 301 and the second circuit board 302 through the second diode. The electrical signal then passes through the second diode and then through the fourth diode, and is transmitted to the Type-C interface 401 by the fourth diode. If the Type-C interface 401 is also interconnected with the Type-C interface 401 of other optical communication devices, the Type-C interface 401 can also supply power to other optical communication devices.

[0085] When power is supplied to the optical communication device through the Type-C interface 401, the electrical signal is transmitted to the first circuit board 301 and the second circuit board 302 through the third diode.

[0086] refer to Figure 12 In this embodiment of the application, the Type-C interface 401 has a total of 24 pins, and the order of pin definition is the same after flipping the A side and the B side.

[0087] The 12 pins on side A are defined as follows: A1-GND, A2-MDI1+, A3-MDI3+, A4-5V, A5-CC1, A6-NC, A7-NC, A8-NC, A9-5V, A10-MDI4+, A11-MDI2+, and A12-GND.

[0088] The 12 pins on side B are defined as follows: B1-GND, B2-MDI 2-, B3-MDI 4-, B4-5V, B5-CC2, B6-NC, B7-NC, B8-NC, B9-5V, B10-MDI3-, B11-MDI1-, B12-GND.

[0089] Two 5V / 5V pairs, two GND / GND pairs, CC1, and CC2 pins are used for charging and powering the Type-C interface 401, so that the Type-C interface 401 can be connected to an external power supply device, or so that the Type-C interface 401 can supply power to other communication devices.

[0090] Four pairs of pins: MDI1+ / MDI1-, MDI2+ / MDI2-, MDI3+ / MDI3-, MDI4+ / MDI4-, are used to send and receive data signals so that the Type-C interface 401 can transmit data signals; at the same time, the symmetry of the four pairs of pins is used to realize the positive and negative connection functions of the Type-C interface 401.

[0091] The NC pin is left floating and not connected.

[0092] This enables the Type-C interface 401 to connect to external power supply devices, connect to external devices to be charged, and transmit data signals.

[0093] In this embodiment of the application, an optical fiber communication system includes multiple optical communication devices described above. Any two optical communication devices are interconnected via their Type-C interfaces 401 to achieve cascaded deployment and facilitate network expansion.

[0094] In summary, this application provides an optical communication device and an optical fiber communication system. The optical communication device includes a rectangular housing 100 and an optical module 200. The rectangular housing 100 includes a first sidewall 1011 and a second sidewall 1012, which are opposite each other along a first direction (the x-axis shown in the figure). The optical module 200 is disposed in the rectangular housing 100. The optical module 200 has a plug-in interface 201, and the plug-in direction of the plug-in interface 201 forms a first angle with the first direction (the x-axis shown in the figure), which is greater than 0° and less than 90°. The plug-in direction of the optical cable forms a first angle with the first direction (the x-axis shown in the figure), meaning the optical module 200 is placed obliquely in the rectangular housing 100. This solves the problem that optical modules 200 of various sizes cannot be adapted to small optical communication devices, and allows for the installation of larger optical modules 200 without increasing the size of the rectangular housing 100.

[0095] The various embodiments or embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referred to each other.

[0096] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0097] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0098] It should be readily understood that the terms “on,” “above,” and “on top of” in this disclosure should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on top of something” but also “on top of something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0099] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90 degrees or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
