Description

Technical Field

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

[0002] With the development of new business and application models such as cloud computing, mobile internet, and video, the advancement of optical communication technology has become increasingly important. In optical communication technology, optical modules are the tools for converting between photoelectric signals and signals, and are one of the key components in optical communication equipment. Furthermore, with the evolving needs of optical communication technology, the transmission rate of optical modules is constantly increasing. Summary of the Invention

[0003] Some embodiments provide an optical module that facilitates switching between pluggable and fixed connection modes between the fiber optic adapter and the fiber optic connector.

[0004] Some embodiments provide an optical module, including:

[0005] The fiber optic adapter is located at the optical port of the optical module;

[0006] Fiber optic connector, locking the connection of the fiber optic adapter; the fiber optic connector includes:

[0007] A connector body is disposed on an optical fiber; one end of the connector body forms a limiting stage.

[0008] A slider is disposed on the connector body; one end of the slider forms a gap with the limiting platform; the slider moves toward the limiting platform to unlock the fiber optic connector from the fiber optic adapter;

[0009] Anti-unlocking component, connected to the fiber optic connector; the anti-unlocking component includes:

[0010] A connecting mechanism that connects to the outer side of one end of the connector body;

[0011] A locking mechanism is disposed inside the connecting mechanism; the locking mechanism is embedded in the interval and prevents the slider from moving in the direction of the limiting platform.

[0012] One of the above technical solutions has the following advantages or beneficial effects: when the fiber optic connector and fiber optic adapter are locked together, if the slider is dragged to move in the direction of the limiting platform, one end of the slider will be close to the side of the limiting platform, the distance between the end face of the slider and the side of the limiting platform will decrease, the fiber optic connector and fiber optic adapter will be unlocked, and thus the fiber optic connector and fiber optic adapter can be disconnected.

[0013] When the anti-unlocking component is installed on the fiber optic connector, it is connected to a limiting stage at one end of the slider via a connecting mechanism. A locking mechanism is embedded in the gap, occupying the gap. When the slider is dragged by external force, the anti-unlocking component prevents the slider from moving because the gap is occupied, thus preventing the fiber optic connector and adapter from unlocking and achieving a fixed connection between them.

[0014] When the anti-unlocking component is installed on the fiber optic connector, the fiber optic connector and fiber optic adapter cannot be unlocked; when the anti-unlocking component is removed from the fiber optic connector, the fiber optic connector and fiber optic adapter can be unlocked. Thus, the anti-unlocking component allows for switching between pluggable and fixed connections between the fiber optic connector and fiber optic adapter. Compared to fixing the slider to the connector body with adhesive to achieve a fixed connection between the fiber optic connector and fiber optic adapter, this method facilitates module repair and adapts to the various usage modes of the optical module.

[0015] In some embodiments, an optical module is provided, wherein the connection mechanism includes a first connector and a second connector; the first connector and the second connector include:

[0016] The locking mechanism is provided on the inner side of the bridging part;

[0017] A first connecting portion is located at one end of the bridging portion and is fitted to the side of the connector body; a snap fastener is formed on the first connecting portion;

[0018] The second connecting part is located at the other end of the bridging part and is fitted to the side of the connector body; a slot is formed on the second connecting part;

[0019] The buckle on the first connector can be detachably connected to the slot on the second connector, and the slot on the first connector can be detachably connected to the buckle on the second connector.

[0020] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: The connection mechanism includes a first connector and a second connector. When the connection mechanism is connected to the fiber optic connector, it facilitates the assembly of the anti-unlocking component onto the fiber optic connector. Both the first connector and the second connector include a first connecting portion, a bridging portion, and a second connecting portion connected in sequence. A buckle is formed on the first connecting portion, and a slot is formed on the second connecting portion. The buckle on the first connector is detachably connected to the slot on the second connector, and the slot on the first connector is detachably connected to the buckle on the second connector, facilitating the assembly of the first connector and the second connector onto the fiber optic connector, thereby facilitating the placement of the locking mechanism within the gap. Based on the detachable connection via the slot and buckle, the first connector and the second connector are assembled to connect to the connector body, allowing the anti-unlocking component to be miniaturized as much as possible. A bridging portion is formed in the middle of the first connector and the middle of the second connector, and connecting portions are formed at both ends of the first connector and the two ends of the second connector. The first connector and the second connector are connected to each other through the connecting portions, and a connecting limiting platform is assembled on the inner side of the connecting portions, facilitating the assembly of the first connector and the second connector to the fiber optic connector. A locking mechanism is provided on the bridging section, which allows the locking mechanism to be conveniently installed within the interval.

[0021] In some embodiments, an optical module is provided in which the width of the bridging portion is smaller than the width of the first connecting portion, and the width of the bridging portion is smaller than the width of the second connecting portion;

[0022] The locking mechanism includes a first locking protrusion and a second locking protrusion, wherein the first locking protrusion connects the first connecting portion and the bridging portion, and the second locking protrusion connects the second connecting portion and the bridging portion;

[0023] The first locking protrusion and the second locking protrusion are embedded in and connected to the interval.

[0024] Another technical solution described above has the following advantages or beneficial effects: the width of the bridging portion is smaller than the width of the first connecting portion, and the width of the bridging portion is smaller than the width of the second connecting portion, which helps to control the size of the anti-unlocking component and facilitates its miniaturization. The locking mechanism includes a first locking protrusion and a second locking protrusion, with a connecting gap between them, which facilitates the locking mechanism to be embedded in the connecting gap, ensuring the blocking strength of the locking mechanism, and thus ensuring the locking strength of the anti-unlocking component in locking the fiber optic connector.

[0025] In some embodiments, an optical module is provided, wherein a first blocking surface is formed on the first locking protrusion, a third blocking surface is formed on the second locking protrusion, and a second blocking surface is formed on the bridging portion;

[0026] The width of the first locking protrusion is smaller than the width of the bridging portion, and the width of the second locking protrusion is smaller than the width of the bridging portion;

[0027] The first blocking surface, the second blocking surface, and the third blocking surface are flush, and the first blocking surface, the second blocking surface, and the third blocking surface block the end face of the slider; the surface of the bridging portion is higher than the surface of the slider.

[0028] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: a first blocking surface is formed on the first locking protrusion, a second blocking surface is formed on the bridging portion, and a third blocking surface is formed on the second locking protrusion. The first, second, and third blocking surfaces are flush and block the end face of the slider. This facilitates full contact between the first, second, and third blocking surfaces with the slider, thereby increasing the blocking performance of the anti-unlocking component on the slider. The width of the first locking protrusion is smaller than the width of the bridging portion, and the width of the second locking protrusion is smaller than the width of the bridging portion, which facilitates the assembly and connection of the first and second locking protrusions and allows the slider to be blocked through the bridging portion. The surface of the bridging portion is higher than the surface of the slider, which facilitates preventing the slider from moving towards the limiting stage after deformation, reducing the risk of unlocking of the fiber optic connector and fiber optic adapter.

[0029] In some embodiments, an optical module is provided, wherein a first connecting portion has a latch and a positioning hole, and a second connecting portion has a slot and a positioning post;

[0030] The connecting mechanism includes a first connector and a second connector. The buckle on the first connector is connected to the slot of the second connector, the slot on the first connector is connected to the buckle of the second connector, the positioning hole on the first connector is positioned and connected to the positioning post of the second connector, and the positioning post on the first connector is positioned and connected to the positioning hole of the second connector.

[0031] Another technical solution described above has the following advantages or beneficial effects: The connecting portion of the first connector has a buckle, a positioning hole, a slot, and a positioning post; the connecting portion of the second connector also has a buckle, a positioning hole, a slot, and a positioning post. The buckle on the first connector is assembled with the slot on the second connector; the slot on the first connector is assembled with the buckle on the second connector; the positioning hole on the first connector is positioned with the positioning post on the second connector; and the positioning post on the first connector is positioned with the positioning hole on the second connector, facilitating a precise and fixed connection between the first and second connectors.

[0032] In some embodiments, an optical module is provided, wherein the locking mechanism includes a first limiting rib and a second limiting rib, the first limiting rib extending from one end of the bridging portion to the other end of the bridging portion, the end of the first limiting rib being connected to the first connecting portion, and the end of the second limiting rib being connected to the second connecting portion;

[0033] There is a gap between the inner side of the first limiting rib and the inner side of the second limiting rib. The outer side of the first limiting rib blocks the end face connected to the slider, and the outer side of the second limiting rib abuts against the limiting platform.

[0034] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: The locking mechanism includes a first limiting rib and a second limiting rib, which extend from one end of the bridging portion to the other end. The first limiting rib connects to the first connecting portion, and the end of the second limiting rib connects to the second connecting portion, which facilitates increasing the connection strength between the first limiting rib, the second limiting rib, and the bridging portion. There is a gap between the inner surface of the first limiting rib and the inner surface of the second limiting rib. The outer surface of the first limiting rib blocks the end face of the connecting slider, and the outer surface of the second limiting rib abuts against the limiting platform, which facilitates blocking the slider from moving into the gap through the first and second limiting ribs, ensuring the anti-unlocking performance of the anti-unlocking component.

[0035] In some embodiments, an optical module is provided, wherein the connection mechanism includes a first connector and a second connector; a buckle is formed on the connection portion of the first connector, and a slot is formed on the connection portion of the second connector, wherein the buckle is assembled to the slot;

[0036] or,

[0037] An assembly post is formed on the connecting portion of the first connector, and an assembly hole is formed on the connecting portion of the second connector, wherein the assembly post is assembled to the assembly hole.

[0038] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: a buckle is provided on the connecting part of the first connector, and a slot is formed on the connecting part of the second connector. The first connector and the second connector are fixedly connected by assembling the buckle and the slot, which facilitates the fixed connection of the first connector to the second connector.

[0039] Alternatively, an assembly post is formed on the connecting part of the first connector, and an assembly hole is formed on the connecting part of the second connector. The first connector and the second connector are fixedly connected by assembling the assembly post and the assembly hole, which facilitates the fixed connection of the first connector to the second connector.

[0040] Some embodiments provide an optical module, including:

[0041] The fiber optic adapter is located at the optical port of the optical module;

[0042] Fiber optic connector, locking the connection of the fiber optic adapter; the fiber optic connector includes:

[0043] A connector body is disposed on an optical fiber; one end of the connector body forms a limiting stage.

[0044] A slider is disposed on the surface of the connector body; one end of the slider forms a gap with the limiting platform; the slider moves toward the limiting platform to unlock the fiber optic connector from the fiber optic adapter;

[0045] Anti-unlocking component, connected to the fiber optic connector; the anti-unlocking component includes:

[0046] The first connector is connected to one side of the connector body;

[0047] The second connector is connected to the other side of the connector body; one end of the first connector is detachably connected to one end of the second connector, and the other end of the first connector is detachably connected to the other end of the second connector.

[0048] A locking mechanism is disposed inside the first connector and / or the second connector; the locking mechanism is embedded in the interval and prevents the slider from moving in the direction of the limiting platform.

[0049] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: When the fiber optic connector and fiber optic adapter are locked together, if the slider is dragged to move in the direction of the limiting platform, one end of the slider is close to the side of the limiting platform, the distance between the end face of the slider and the side of the limiting platform is reduced, the fiber optic connector and fiber optic adapter are unlocked, and thus the fiber optic connector and fiber optic adapter can be disconnected.

[0050] The anti-unlocking component includes a first connector and a second connector. One end of the first connector is connected to one end of the second connector, and the other end of the first connector is connected to the other end of the second connector. Both the first connector and the second connector are connected to a limiting platform, which facilitates the connection between the anti-unlocking component and the fiber optic connector.

[0051] When the anti-unlocking component is installed on the fiber optic connector, it is connected to a limiting stage via a first connector and a second connector, positioned at one end of the slider. This allows the locking mechanism to be embedded in the gap, occupying the gap. When the slider is dragged by external force, the anti-unlocking component prevents the slider from moving because the gap is occupied, thus preventing the fiber optic connector and fiber optic adapter from unlocking and achieving a fixed connection between them.

[0052] When the anti-unlocking component is attached to the fiber optic connector, the fiber optic connector and fiber optic adapter cannot be unlocked; when the anti-unlocking component is removed from the fiber optic connector, the fiber optic connector and fiber optic adapter can be unlocked. Thus, the anti-unlocking component allows for switching between pluggable and fixed connection modes between the fiber optic connector and fiber optic adapter.

[0053] In some embodiments, an optical module is provided, wherein the first connector includes a bridging portion and a first connecting portion and a second connecting portion disposed at both ends of the bridging portion; the width of the first connecting portion is greater than the width of the bridging portion, and the width of the second connecting portion is greater than the width of the bridging portion;

[0054] The locking mechanism includes a first locking protrusion and a second locking protrusion, wherein the first locking protrusion connects the first connecting portion and the bridging portion, and the second locking protrusion connects the second connecting portion and the bridging portion;

[0055] The first locking protrusion and the second locking protrusion are embedded in and connected to the interval.

[0056] Another technical solution described above has the following advantages or beneficial effects: the first connector includes a bridging portion, one end of which is provided with a first connecting portion, and the other end of which is provided with a second connecting portion. The first connecting portion and the second connecting portion are used to achieve a fixed connection between the first connector and the second connector. The width of the first connecting portion is greater than the width of the bridging portion, and the width of the second connecting portion is greater than the width of the bridging portion, which facilitates increasing the connection strength between the first connector and the second connector, and also facilitates control over the size of the anti-unlocking component, preventing the unlocking component from becoming too large.

[0057] The locking mechanism includes a first locking protrusion and a second locking protrusion. The first locking protrusion connects the first connecting part and the bridging part, and the second locking protrusion connects the second connecting part and the bridging part. This facilitates increasing the connection strength between the first locking protrusion and the second locking protrusion and the first connecting member, and helps prevent damage to the first locking protrusion and the second locking protrusion caused by external forces generated during slider movement.

[0058] In some embodiments, an optical module is provided, wherein a first groove is formed on the first locking protrusion, the depth of the first groove being less than the thickness of the first locking protrusion; and a second groove is formed on the second locking protrusion, the depth of the second groove being less than the thickness of the second locking protrusion.

[0059] A first blocking surface is formed on the side of the first locking protrusion, a second blocking surface is formed on the side of the bridging portion, and a third blocking surface is formed on the side of the second locking protrusion.

[0060] The first blocking surface, the second blocking surface, and the third blocking surface block the end face of the slider.

[0061] Another technical solution in the above-mentioned technical solution has the following advantages or beneficial effects: A first groove is formed on the first locking protrusion, which reduces defects generated during the forming of the first locking protrusion, increases the strength of the first locking protrusion, and thus enhances the strength of the first locking protrusion in blocking the slider. A second groove is formed on the second locking protrusion, which reduces defects generated during the forming of the second locking protrusion, increases the strength of the second locking protrusion, and thus enhances the strength of the second locking protrusion in blocking the slider.

[0062] A first blocking surface is formed on the first locking protrusion, a second blocking surface is formed on the bridging portion, and a third blocking surface is formed on the second locking protrusion. The first, second, and third blocking surfaces are flush and block the end face of the slider. This facilitates full contact between the first, second, and third blocking surfaces and the slider, thereby increasing the blocking performance of the anti-unlocking component on the slider.

[0063] Some embodiments provide an optical module, including:

[0064] The first fiber optic adapter is located at the optical port of the optical module;

[0065] The second fiber optic adapter is located at the optical port of the optical module and is arranged side by side with the first fiber optic adapter;

[0066] The first fiber optic connector is locked to the first fiber optic adapter;

[0067] A second fiber optic connector is used to lock the connection of the second fiber optic adapter; the first fiber optic connector and the second fiber optic connector include:

[0068] A connector body is mounted on an optical fiber; a limiting stage is formed at one end of the connector body.

[0069] A slider is disposed on the connector body; one end of the slider forms a gap with the limiting platform; the slider moves toward the limiting platform to unlock the corresponding fiber optic connector and fiber optic adapter.

[0070] The first anti-unlocking component is connected to the first optical fiber connector;

[0071] The second anti-unlocking component is connected to the second fiber optic connector; the first anti-unlocking component and the second anti-unlocking component include:

[0072] A connecting mechanism that connects to the outer side of one end of the connector body;

[0073] A locking mechanism is disposed inside the connecting mechanism; the locking mechanism is embedded in the interval and prevents the slider from moving in the direction of the limiting platform.

[0074] One of the above technical solutions has the following advantages or beneficial effects: The first fiber optic connector and the first fiber optic adapter are locked together. If the slider on the first fiber optic connector is dragged towards the direction of the limiting platform, one end of the slider approaches the side of the limiting platform, reducing the distance between the slider end face and the side of the limiting platform, thus unlocking the first fiber optic connector and the first fiber optic adapter, thereby disengaging the first fiber optic connector from the first fiber optic adapter. Similarly, the second fiber optic connector and the second fiber optic adapter are locked together. If the slider on the second fiber optic connector is dragged towards the direction of the limiting platform, one end of the slider approaches the side of the limiting platform, reducing the distance between the slider end face and the side of the limiting platform, thus unlocking the second fiber optic connector from the second fiber optic adapter, thereby disengaging the second fiber optic connector from the second fiber optic adapter.

[0075] When the first anti-unlocking component is installed on the first fiber optic connector, it is connected to a limiting platform at one end of the slider via a connecting mechanism. A locking mechanism is embedded in the gap, occupying the gap. When the slider on the first fiber optic connector is dragged by external force, the first anti-unlocking component prevents the slider from moving because the gap is occupied, thus preventing the first fiber optic connector from unlocking the first fiber optic adapter and achieving a fixed connection between the first fiber optic connector and the first fiber optic adapter.

[0076] When the second anti-unlocking component is installed on the second fiber optic connector, it is connected to a limiting platform at one end of the slider via a connecting mechanism. A locking mechanism is embedded in the gap, occupying the gap. When the slider on the second fiber optic connector is dragged by external force, the second anti-unlocking component prevents the slider from moving because the gap is occupied, thus preventing the second fiber optic connector from unlocking the second fiber optic adapter and achieving a fixed connection between them.

[0109] The embodiments of this disclosure will now be described clearly and in detail with reference to the accompanying drawings. However, the described embodiments are merely some, and not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0110] Unless the context otherwise requires, throughout the specification and claims, the term "comprising" is interpreted as open and inclusive, meaning "including, but not limited to"; the terms "first" and "second" should not be construed as indicating or implying relative importance or indicating an upper limit on the number; the term "multiple" means two or more; the term "connection" should be interpreted broadly, for example, "connection" can be a fixed connection, a detachable connection, or an integral part, and can be a direct connection or an indirect connection through an intermediate medium; the use of the terms "applicable to" or "configured to" implies open and inclusive language, which does not exclude applicability to or configuration to devices performing additional tasks or steps; descriptions such as "parallel," "perpendicular," "identical," "consistent," and "aligned" are not limited to absolute mathematical theoretical relationships, but also include acceptable error ranges arising in practice, and differences based on the same design concept but due to manufacturing reasons.

[0111] In optical communication technology, to establish information transmission between information processing devices, information is loaded onto light, and the speed of light propagation is used to transmit the information. This light carrying information is called an optical signal. When optical signals are transmitted in optical information transmission equipment, optical power loss can be reduced, enabling long-distance transmission of optical signals. At the same time, the cost of optical information transmission equipment such as optical fibers is lower than that of electrical information transmission equipment such as copper wires. Therefore, optical communication technology can achieve high-speed, long-distance, and low-cost information transmission.

[0112] Information processing equipment typically includes optical network units (ONUs), gateways, routers, switches, mobile phones, computers, servers, tablets, televisions, etc., while optical information transmission equipment typically includes optical fibers and optical waveguides. Information processing equipment can only recognize and process electrical signals, while optical communication technology uses optical signals for transmission, requiring optical modules to convert between optical and electrical signals.

[0113] An optical module enables the conversion between optical signals and electrical signals between information processing equipment and optical information transmission equipment. In some embodiments, at least one of the optical signal input or output terminals of the optical module is connected to an optical fiber, and at least one of the electrical signal input or output terminals of the optical module is connected to an optical network terminal. A first optical signal from the optical fiber is transmitted to the optical module, which converts the first optical signal into a first electrical signal and transmits the first electrical signal to the optical network terminal. A second electrical signal from the optical network terminal is transmitted to the optical module, which converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber.

[0114] Since multiple information processing devices can transmit information via electrical signals, at least one of these devices needs to be directly connected to the optical module, rather than all of them. Here, the information processing device directly connected to the optical module is also referred to as the host computer of the optical module. Furthermore, the optical signal input or output terminal of the optical module is called the optical port, and the electrical signal input or output terminal is called the electrical port.

[0115] Figure 1 This is a partial structural diagram of an optical communication system according to some embodiments. Figure 1 As shown, the optical communication system mainly includes a remote information processing device 1000, a local information processing device 2000, a host computer 100 for optical modules, an optical module 200, an optical fiber 101, and a network cable 103. Among them, the optical fiber 101 is an optical information transmission device, and the network cable 103 is an electrical information transmission device.

[0116] In some embodiments, one end of the optical fiber 101 extends toward the remote information processing device 1000, and the other end of the optical fiber 101 is connected to the optical module 200 through the optical port of the optical module 200. The optical signal can undergo total internal reflection in the optical fiber 101, and the propagation of the optical signal in the direction of total internal reflection can almost maintain the original optical power. The optical signal undergoes multiple total internal reflections in the optical fiber 101 to transmit the optical signal from the remote information processing device 1000 to the optical module 200, or to transmit the optical signal from the optical module 200 to the remote information processing device 1000, thereby realizing long-distance information transmission based on low power loss.

[0117] The optical communication system includes one or more optical fibers 101. In some embodiments, the optical fiber 101 is detachably connected to the optical module 200; in some embodiments, the optical fiber 101 is non-detachably connected to the optical module 200.

[0118] The host computer 100 is configured to provide data signals to the optical module 200, or receive data signals from the optical module 200, or monitor or control the working status of the optical module 200.

[0119] The host computer 100 includes a housing for accommodating the optical module 200, and an optical module interface 102 disposed on the housing. The optical module 200 is inserted into the housing through the optical module interface 102 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the optical module 200.

[0120] The host computer 100 also includes an external power interface that can connect to an electrical signal network. In some embodiments, the external power interface includes a Universal Serial Bus (USB) interface or a network cable interface 104. The network cable interface 104 is configured to connect a network cable 103 to establish a unidirectional or bidirectional electrical signal connection between the host computer 100 and the network cable 103.

[0121] One end of the network cable 103 is connected to the local information processing device 2000, and the other end is connected to the host computer 100, so as to establish an electrical signal connection between the local information processing device 2000 and the host computer 100 through the network cable 103. In some embodiments, a third electrical signal emitted by the local information processing device 2000 is transmitted to the host computer 100 through the network cable 103. The host computer 100 generates a second electrical signal based on the third electrical signal. The second electrical signal from the host computer 100 is transmitted to the optical module 200. The optical module 200 converts the second electrical signal into a second optical signal and transmits the second optical signal to the optical fiber 101. The second optical signal is transmitted in the optical fiber 101 to the remote information processing device 1000.

[0122] In some embodiments, a first optical signal from a remote information processing device 1000 is transmitted through an optical fiber 101, and the first optical signal from the optical fiber 101 is transmitted to an optical module 200. The optical module 200 converts the first optical signal into a first electrical signal, and transmits the first electrical signal to a host computer 100. The host computer 100 generates a fourth electrical signal based on the first electrical signal and transmits the fourth electrical signal to a local information processing device 2000.

[0123] In some embodiments, the optical module is a tool for converting optical signals to electrical signals. During the conversion process, the information does not change, but the encoding or decoding method of the information changes.

[0124] In addition to optical network terminals, the host computer 100 also includes optical line terminals (OLTs), optical network equipment (ONTs), or data center servers.

[0125] Figure 2 This is a partial structural diagram of a host computer according to some embodiments. To clearly show the connection relationship between the optical module 200 and the host computer 100, Figure 2 Only the structure of the host computer 100 related to the optical module 200 is shown. For example... Figure 2As shown, in some embodiments, the host computer 100 further includes a PCB circuit board 105 disposed in the receiving cavity, and a cage 106 disposed on the surface of the PCB circuit board 105; the optical module 200 is inserted into the cage 106 and fixed by the cage 106.

[0126] In some embodiments, a heat sink 107 is provided on the cage 106 to dissipate heat for the optical module; in some embodiments, the heat sink 107 has protruding structures such as fins to increase the heat dissipation area.

[0127] In some embodiments, an electrical connector is provided inside the cage 106, which is configured to connect to the electrical port of the optical module 200.

[0128] In some embodiments, the optical module 200 is inserted into the cage 106 of the host computer 100, and the cage 106 fixes the optical module 200. The heat generated by the optical module 200 is conducted to the cage 106 and then diffused through the heat sink 107.

[0129] In some embodiments, the optical module 200 is inserted into the cage 106 of the host computer 100, and the electrical port of the optical module 200 is connected to the electrical connector inside the cage 106, thereby establishing an electrical signal connection between the optical module 200 and the host computer 100.

[0130] In some embodiments, the optical port of the optical module 200 is connected to the optical fiber 101, thereby enabling the optical module 200 to establish an optical signal connection with the optical fiber 101.

[0131] Figure 3 This is a structural diagram of an optical module according to some embodiments. Figure 4 This is an exploded view of an optical module according to some embodiments. For example... Figure 3 and Figure 4 As shown, in some embodiments, the optical module 200 includes a shell, which comprises an upper shell 201 and a lower shell 202. The upper shell 201 covers the lower shell 202, forming two openings 203 and 204, one of which is an electrical port and the other is an optical port. In some embodiments, the shell forms an opening that serves as both an electrical port and an optical port.

[0132] In some embodiments, the upper housing 201 and the lower housing 202 are made of metal materials, which facilitates electromagnetic shielding and heat dissipation.

[0133] The assembly method of combining the upper housing 201 and the lower housing 202 facilitates the installation of the circuit board 300, the light emitting component 400, the light receiving component 500, etc. into the housing. The upper housing 201 and the lower housing 202 can encapsulate and protect the above-mentioned devices.

[0134] The direction of the line connecting the two openings 203 and 204 can be consistent with or inconsistent with the length direction of the optical module 200. For example, opening 203 is located at the end of the optical module 200. Figure 3 The opening 204 is also located at the end of the optical module 200 (right end). Figure 3 (The left end). Alternatively, opening 203 is located at the end of optical module 200, while opening 204 is located on the side of optical module 200.

[0135] In some embodiments, the lower housing 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and perpendicular to the base plate 2021; the upper housing 201 includes a cover plate 2011, which covers the two lower side plates 2022 of the lower housing 202 to form the aforementioned housing.

[0136] In some embodiments, the lower housing 202 includes a base plate 2021 and two lower side plates 2022 located on both sides of the base plate 2021 and perpendicular to the base plate 2021; the upper housing 201 includes a cover plate 2011 and two upper side plates located on both sides of the cover plate 2011 and perpendicular to the cover plate 2011. The two upper side plates and the two lower side plates 2022 are combined to realize that the upper housing 201 covers the lower housing 202.

[0137] like Figure 4 As shown, in some embodiments, the optical module includes a fiber optic adapter 700 located at opening 204, the fiber optic adapter 700 being used to connect to the optical fiber 101. Exemplarily, the fiber optic adapter 700 can be pluggably connected to the optical fiber 101 or can be fixedly connected to the optical fiber 101.

[0138] In some embodiments, the fiber optic adapter 700 is connected to the optical transmitting component 400 or the optical receiving component 500 via an optical fiber ribbon. The fiber optic adapter 700 is used to connect the optical fiber ribbon to the optical fiber 101.

[0139] like Figure 3 and Figure 4As shown, in some embodiments, the optical module includes a circuit board 300 disposed within a housing. The circuit board 300 includes circuit traces, electronic components, and chips, etc. The electronic components and chips are connected according to the circuit design through the circuit traces to realize functions such as power supply, electrical signal transmission, and grounding. Electronic components may include capacitors, resistors, transistors, and metal-oxide-semiconductor field-effect transistors (MOSFETs). Chips may include microcontroller units (MCUs), laser driver chips, transimpedance amplifiers (TIAs), limiting amplifiers (LAs), clock and data recovery chips (CDRs), power management chips, and digital signal processing (DSP) chips.

[0140] In some embodiments, the circuit board includes a rigid circuit board, which, due to its relatively rigid material, can also serve a load-bearing function, such as being able to stably support the aforementioned electronic components and chips; the rigid circuit board can also be inserted into an electrical connector in the cage 106 of the host computer 100.

[0141] In some embodiments, the circuit board further includes a flexible circuit board, which can be used independently or in conjunction with a rigid circuit board.

[0142] In some embodiments, the circuit board further includes gold fingers formed on its end surface, the gold fingers consisting of a plurality of independent pins.

[0143] In some implementations, the gold fingers 301 are disposed on one side of the surface of the circuit board 300 (e.g., Figure 4 (as shown on the upper surface); In some implementations, the gold fingers 301 are disposed on the upper and lower surfaces of the circuit board 300 to provide a greater number of pins, thereby adapting to situations where the number of pins is required.

[0144] In some implementations, the gold fingers of the circuit board extend from the electrical port and are inserted into the electrical connector of the host computer 100; the circuit board is inserted into the cage 106, and the gold fingers 301 are connected to the electrical connector inside the cage 106. The gold fingers 301 are configured to establish an electrical connection with the host computer, enabling electrical connection functions such as power supply, grounding, two-wire synchronous serial (Inter-Integrated Circuit, I2C) signal transmission, and data signal transmission.

[0145] In some embodiments, the optical module 200 further includes an unlocking component 600 located outside its housing. The unlocking component 600 is configured to establish a fixed connection between the optical module 200 and the host computer, or to release the fixed connection between the optical module 200 and the host computer.

[0146] For example, the unlocking component 600 is located on the outside of the two lower side plates 2022 of the lower housing 202, and includes a locking component that matches the cage 106 of the host computer 100. When the optical module 200 is inserted into the cage 106, the locking component of the unlocking component 600 fixes the optical module 200 in the cage 106; when the unlocking component 600 is pulled, the locking component of the unlocking component 600 moves accordingly, thereby changing the connection relationship between the locking component and the host computer, so as to release the fixation between the optical module 200 and the host computer, thereby allowing the optical module 200 to be pulled out of the cage 106.

[0147] In some embodiments, the light emitting component 400 and the light receiving component 500 may be physically separated from the circuit board 300, and then electrically connected to the circuit board 300 through corresponding flexible circuit boards or electrical connectors.

[0148] In some embodiments, at least one of the light emitting component 400 or the light receiving component 500 is located on the side of the circuit board 300 away from the gold finger 301.

[0149] In some embodiments, at least one of the light emitting component or the light receiving component may be directly disposed on the circuit board 300. For example, at least one of the light emitting component or the light receiving component may be disposed on the surface of the circuit board 300 or the side of the circuit board 300.

[0150] Figure 5 This is a usage diagram of an optical module according to some embodiments. For example... Figure 5 As shown, in some embodiments, one end of the optical fiber 101 is connected to the optical module 200a, and the other end of the optical fiber 101 is connected to the optical module 200b. Exemplarily, optical fiber connectors can be provided at both ends of the optical fiber 101, and the optical fiber 101 is connected to the optical module 200a and the optical module 200b respectively through the optical fiber connectors.

[0151] Figure 6 This is a structural diagram of another optical module according to some embodiments. Figure 7 This is an exploded view of yet another optical module according to some embodiments. For example... Figure 6 and Figure 7As shown, in some embodiments, an optical fiber connector 800 is provided at the end of the optical fiber 101, and the optical fiber connector 800 is connected to the optical fiber adapter 700. Exemplarily, the optical fiber connector 800 is pluggably connected to the optical fiber adapter 700. When the end of the optical fiber connector 800 is inserted into the optical fiber adapter 700, the optical fiber connector 800 and the optical fiber adapter 700 are locked; when it is necessary to pull out the optical fiber connector 800, an external force is applied to the optical fiber connector 800, and the optical fiber connector 800 and the optical fiber adapter 700 are unlocked.

[0152] In some embodiments, an anti-unlocking component 900 may be provided on the fiber optic connector 800. The anti-unlocking component 900 is provided on the fiber optic connector 800 and is used to securely lock the fiber optic connector 800 and the fiber optic adapter 700, so that the fiber optic connector 800 and the fiber optic adapter 700 are fixedly connected, that is, the fiber optic connector 800 and the fiber optic adapter 700 cannot be easily unlocked.

[0153] Figure 8A This is a structural diagram of a fiber optic connector according to some embodiments. Figure 8B This is a cross-sectional view of a fiber optic connector according to some embodiments. Figure 8A and Figure 8B As shown, in some embodiments, the fiber optic connector 800 includes a connector body 810, the end of which connects to the fiber optic cable 101. The connector body 810 mates with the fiber optic adapter 700, and the fiber optic cable 101 is fixed relative to the fiber optic adapter 700 via the connector body 810.

[0154] In some embodiments, the fiber optic connector 800 may include a slider 820 disposed on the connector body 810. The slider 820 is movable along an extension of the connector body 810; for example, the slider 820 moves along... Figure 8A The slider moves in the direction of the arrow shown. For example, the slider 820 can move within a preset length range of the connector body 810.

[0155] In some embodiments, the connector body 810 has a locking portion 811, which can lock the connection of the fiber optic adapter 700. The locking portion 811 is located below the slider 820, and the locking portion 811 cooperates with the slider 820 to lock the connector body 810 and the fiber optic adapter 700. Exemplarily, locking portions 811 are respectively provided on both sides of the connector body 810.

[0156] In some embodiments, a limiting stage 812 is formed on the side of one end of the connector body 810, and a gap 801 is formed between the side of the limiting stage 812 and one end of the slider 820. When the slider 820 moves along the connector body 810, one end of the slider 820 approaches the limiting stage 812, and the gap 801 between one end of the slider 820 and the limiting stage 812 shortens.

[0157] Figure 8C A cross-sectional view of an optical module according to some embodiments. Figure 1 , Figure 8C This illustrates the locked state of a fiber optic connector and fiber optic adapter. (Example) Figure 8C As shown, in some embodiments, the fiber optic adapter 700 includes a latch 701 for locking the fiber optic connector 800. Exemplarily, when the fiber optic connector 800 is connected to the fiber optic adapter 700, a locking part 811 is fitted onto the inner side of the latch 701, and a slider 820 is fitted onto the outer side of the latch 701. The slider 820, the latch 701, and the locking part 811 are assembled together to lock the latch 701 to the connector body 810, thereby achieving a locking connection between the fiber optic connector 800 and the fiber optic adapter 700.

[0158] In some embodiments, when the slider 820 is dragged toward the limiting stage 812, one end of the slider 820 approaches the side of the limiting stage 812, the slider 820 disengages from the claw 701, the claw 701 disengages from the locking part 811, the fiber optic connector 800 and the fiber optic adapter 700 are unlocked, thereby enabling the fiber optic connector 800 and the fiber optic adapter 700 to disengage.

[0159] In some embodiments, the fiber optic connector 800 may include an elastic element 830, which connects the slider 820 and the connector body 810. The elastic element 830 may be a spring or tension spring, etc. Exemplarily, when unlocking the fiber optic connector 800 and the fiber optic adapter 700, an external force overcomes the deformation force of the elastic element 830, causing the slider 820 to move. When the external force decreases or disappears, the slider 820 returns to its original position under the deformation force of the elastic element 830. Thus, by utilizing the elastic element 830, the locking of the fiber optic connector 800 and the fiber optic adapter 700 can also be reinforced to a certain extent, making it difficult for external forces of less than a certain strength to unlock the slider 820 and the latch 701.

[0160] In some embodiments, to make the fiber optic connector 800 and the fiber optic adapter 700 more difficult to unlock, the optical module 200 may include an anti-unlocking component, which is disposed on the fiber optic connector 800 and is used to block the movement of the slider 820.

[0161] Figure 9A This is a connection state diagram of a fiber optic connector and an anti-unlocking component according to some embodiments. Figure 9BThis is a cross-sectional view of a fiber optic connector and an anti-unlocking component according to some embodiments. Figure 9A and Figure 9B As shown, the fiber optic connector 800 is provided with an anti-unlocking component 900. The anti-unlocking component 900 is located at one end of the connector body 810. The anti-unlocking component 900 is used to block the movement of the slider 820, so as to prevent the fiber optic connector 800 from unlocking the fiber optic adapter 700 and achieve a fixed connection between the fiber optic connector 800 and the fiber optic adapter 700.

[0162] In some embodiments, when the anti-unlocking component 900 is assembled onto the fiber optic connector 800, the fiber optic connector 800 and the fiber optic adapter 700 are not unlockable; when the anti-unlocking component 900 is removed from the fiber optic connector 800, the fiber optic connector 800 and the fiber optic adapter 700 are unlockable. Thus, the anti-unlocking component 900 can accommodate both pluggable and fixed connection modes between the fiber optic connector 800 and the fiber optic adapter 700. For example, the anti-unlocking component 900 detachably connects to the fiber optic connector 800, which is easier to repair than fixing the slider 820 to the connector body 810 with adhesive, as the anti-unlocking component 900 blocks the slider 820.

[0163] In some embodiments, the anti-unlocking component 900 may include a locking mechanism 910. The locking mechanism 910 is embedded within the space 801 to occupy the space 801, preventing the slider 820 from moving towards the limiting stage 812, or reducing the distance the slider 820 moves towards the limiting stage 812, thereby preventing the slider 820 from disengaging from the claw 701. The locking mechanism 910 may be a locking protrusion or a locking rib, etc.

[0164] In some embodiments, the anti-unlocking component 900 may include a connecting mechanism 920, which connects to the connector body 810. The connecting mechanism 920 is disposed outside the locking mechanism 910 to facilitate the connection between the anti-unlocking component 900 and the fiber optic connector 800 and to facilitate the embedding of the locking mechanism 910 within the spacer 801. Exemplarily, the connecting mechanism 920 is sleeved on one end of the connector body 810. For example, the connecting mechanism 920 grips the connecting limiting stage 812.

[0165] Figure 9C A cross-sectional view of an optical module according to some embodiments. Figure 2 , Figure 9B and Figure 9C This illustrates the usage state of an anti-unlocking component. For example... Figure 9B and Figure 9CAs shown, in some embodiments, the connecting mechanism 920 is connected to the connector body 810, and the free end of the locking mechanism 910 is embedded in the interval 801. The locking mechanism 910 occupies the space required for the slider 820 to unlock, and the slider 820 cannot move in the direction of the limiting platform 812 or moves a small distance in the direction of the limiting platform 812, so that the slider 820 cannot be disengaged from the claw 701, thereby keeping the fiber optic connector 800 and the fiber optic adapter 700 locked.

[0166] In some embodiments, one side of the locking mechanism 910 may contact the side of the connecting limiting platform 812, and the other side of the locking mechanism 910 may contact the end face of one end of the connecting slider 820, so that the locking mechanism 910 is interference-fitted within the interval 801, thereby making the slider 820 immovable.

[0167] In some embodiments, one side of the locking mechanism 910 may contact the side of the connecting limiting stage 812, while the other side of the locking mechanism 910 does not contact the end face of one end of the connecting slider 820. The distance between the other side of the locking mechanism 910 and this end face should be less than the minimum unlocking movement distance. Contacting the side of the connecting limiting stage 812 with one side of the locking mechanism 910 facilitates the positioning and assembly of the anti-unlocking component 900. For example, the distance between the other side of the locking mechanism 910 and the end face of the slider 820 is greater than one-quarter of the minimum unlocking movement distance, facilitating the assembly of the locking mechanism 910 with the spacer 801; the distance between the other side of the locking mechanism 910 and the end face of the slider 820 is less than half of the minimum unlocking movement distance, preventing deformation of the slider 820 that could cause the fiber optic connector 800 and fiber optic adapter 700 to unlock.

[0168] In some embodiments, one side of the locking mechanism 910 does not contact the side of the connecting limiting stage 812, while the other side of the locking mechanism 910 may contact the end face of one end of the connecting slider 820. Contacting the end face of one end of the connecting slider 820 with the other side of the locking mechanism 910 facilitates the positioning and assembly of the anti-unlocking component 900. The distance between one side of the locking mechanism 910 and the side of the limiting stage 812 should be less than the minimum unlocking movement distance. For example, the distance between one side of the locking mechanism 910 and the side of the limiting stage 812 is greater than one-quarter of the minimum unlocking movement distance, facilitating the assembly of the locking mechanism 910 with the spacer 801; the distance between the other side of the locking mechanism 910 and the end face of the slider 820 is less than one-third of the minimum unlocking movement distance, reducing the risk of the fiber optic connector 800 and fiber optic adapter 700 unlocking due to movement of the anti-unlocking component 900.

[0169] In some embodiments, the surface of the connecting mechanism 920 is higher than the surface of the slider 820 to prevent the slider 820 from moving toward the limiting stage 812 after deformation, thereby reducing the risk of the fiber optic connector 800 and the fiber optic adapter 700 being unlocked.

[0170] Figure 9D This is a cross-sectional view of a fiber optic connector and fiber optic adapter according to some embodiments. Figure 9B and Figure 9D As shown, in some embodiments, a mounting plane 702 is formed on the fiber optic adapter 700, which is used to mount the housing of the optical module 200. When the fiber optic connector 800 locks the fiber optic adapter 700, the mounting plane 702 protrudes from the surface of the slider 820. The surface of the connection mechanism 920 is lower than the mounting plane 702 or flush with the mounting plane 702, which facilitates control over the length, width, and height dimensions of the fiber optic connector 800 after mounting the anti-unlocking component 900. This allows for minimizing changes in the length, width, and height dimensions of the fiber optic connector 800 after mounting the anti-unlocking component 900 while ensuring the strength of the anti-unlocking component 900, thus adapting to the size requirements of the optical module. For example, it facilitates the use of the anti-unlocking component 900 in optical modules with two fiber optic adapters 700 at the optical port.

[0171] Figure 10A This is an exploded view of a fiber optic connector and an anti-unlocking component according to some embodiments. Figure 10B This is a structural diagram of an anti-unlocking component according to some embodiments. Figure 10C This is an exploded view of an anti-unlocking component according to some embodiments. Figures 10A-10C As shown, in some embodiments, a spacer 801a is formed on one side of the fiber optic connector 800, and a spacer 801b is formed on the other side of the fiber optic connector 800; a plurality of locking mechanisms 910 are formed on the anti-unlocking component 900, and the plurality of mechanisms are distributed at multiple positions of the connecting mechanism 920. Locking mechanisms 910 are provided within spacer 801a and spacer 801b to block the movement of the slider 820 from multiple directions, thereby improving the performance of the anti-unlocking component 900 in blocking the movement of the slider 820.

[0172] In some embodiments, the connecting mechanism 920 includes a first connector 920a and a second connector 920b, with one end of the first connector 920a connected to one end of the second connector 920b, and the other end of the first connector 920a connected to the other end of the second connector 920b. For example, both ends of the first connector 920a can be detachably connected to both ends of the second connector 920b to facilitate the assembly of the anti-unlocking component 900 onto the fiber optic connector 800, thereby miniaturizing the anti-unlocking component 900 as much as possible. For instance, one end of the first connector 920a may be provided with a latch, and one end of the second connector 920b may be provided with a slot; the other end of the first connector 920a may be provided with a slot, and the other end of the second connector 920b may be provided with a latch; or both ends of the first connector 920a may be provided with latches, and both ends of the second connector 920b may be provided with slots; etc.

[0173] In some embodiments, a locking mechanism 910a is provided on the inner side of the first connector 920a, and a locking mechanism 910b is provided on the inner side of the second connector 920b. The first connector 920a and the second connector 920b are connected to the optical fiber connector 800. A connection interval 801a is embedded at the free end of the locking mechanism 910a, and a connection interval 801b is embedded at the free end of the locking mechanism 910b.

Figures 11A-11E The diagram illustrates the structural form of a connecting part and its assembly. The shapes of the first connecting member 920a and the second connecting member 920b may be the same as or similar to those of the connecting members.

[0175] In some embodiments, the connector may include a bridging portion 921. The bridging portion 921 is located on one side of the fiber optic connector 800, and a locking mechanism 910 is provided on the inner side of the bridging portion 921. The outer side of the bridging portion 921 protrudes from the slider 820. The locking mechanism 910 is provided on the inner side of the bridging portion 921.

[0176] In some embodiments, one side of the bridging portion 921 covers the top of the limiting platform 812, and the other side of the bridging portion 921 abuts against the end face of the connecting slider 820.

[0177] In some embodiments, a first locking protrusion 911 and a second locking protrusion 912 are provided on the inner side of the bridging portion 921, and a connecting gap 801 is embedded between the first locking protrusion 911 and the second locking protrusion 912. Exemplarily, the first locking protrusion 911 is located at one end of the inner side of the bridging portion 921, and the second locking protrusion 912 is located at the other end of the inner side of the bridging portion 921, with a gap between the first locking protrusion 911 and the second locking protrusion 912. Of course, in some embodiments, the first locking protrusion 911 may be connected to the second locking protrusion 912 to form a locking protrusion extending through one end of the inner side of the bridging portion 921 to the other end of the inner side of the bridging portion 921.

[0178] In some embodiments, a first groove 9111 may be formed on the first locking protrusion 911. The first groove 9111 can reduce defects generated during the molding of the first locking protrusion 911 and increase the strength of the first locking protrusion 911. Exemplarily, the depth of the first groove 9111 is less than the thickness of the first locking protrusion 911.

[0179] In some embodiments, a second groove 9121 may be formed on the second locking protrusion 912. The second groove 9121 can reduce defects generated during the forming of the second groove 9121 and increase the strength of the second locking protrusion 912. Exemplarily, the depth of the second groove 9121 is less than the thickness of the second locking protrusion 912.

[0180] In some embodiments, a first blocking surface 9112 is formed on the first locking protrusion 911. The first blocking surface 9112 is located on the side of the first locking protrusion 911 and is used to abut against the end face of the blocking slider 820. A second blocking surface 9211 is formed on the bridging portion 921. The second blocking surface 9211 is located on the side of the bridging portion 921 and is used to abut against the end face of the blocking slider 820. The first blocking surface 9112 may be flush with the second blocking surface 9211.

[0181] In some embodiments, a third blocking surface 9122 is formed on the second locking protrusion 912. The third blocking surface 9122 is located on the side of the second locking protrusion 912 and is used to abut against the end face of the blocking slider 820. The third blocking surface 9122 may be flush with the second blocking surface 9211.

[0182] In one embodiment, the width of the first locking protrusion 911 is smaller than the width of the bridging portion 921, and the width of the second locking protrusion 912 is smaller than the width of the bridging portion 921, so as to facilitate the assembly connection of the first locking protrusion 911 and the second locking protrusion 912 with the connection gap 801, and to block the slider 820 through the bridging portion 921.

[0183] In some embodiments, the connector may include a first connecting portion 922 and a second connecting portion 923. One end of the bridging portion 921 is connected to the first connecting portion 922, and the other end of the bridging portion 921 is connected to the second connecting portion 923.

The notch 924 can accommodate the limiting stage 812, which helps to reduce the height of the connector in the direction perpendicular to the extension of the connector body 810. This facilitates control over the size of the anti-unlocking component 900, preventing it from becoming too large, and also facilitates increasing the connection strength between the connectors.

[0186] In some embodiments, the width of the bridging portion 921 is greater than or equal to half the width of the first connecting portion 922, which helps to ensure the strength of the bridging portion 921; the width of the bridging portion 921 is less than or equal to three-quarters of the width of the first connecting portion 922, which helps to control the size of the anti-unlocking component 900.

[0189] In some embodiments, a slot 9231 may be formed on the outer side of the second connecting portion 923, and the slot 9231 penetrates the end face of the second connecting portion 923.

[0190] In some embodiments, a positioning post 9232 may be formed on the end face of the second connecting portion 923; or a positioning hole may be formed on the end face of the second connecting portion 923. Exemplarily, the positioning post 9232 is located near the side of the first connecting portion 922.
