Description

Technical Field

[0001] This application relates to the field of optical fiber communication technology, and in particular to fusion splice trays, optical fiber distribution devices, fusion splice trays with electronic tags, and optical communication devices. Background Technology

[0002] A fusion splice tray is a fiber optic connection distribution device used to connect optical fibers to patch cords or between two patch cords. It is now widely used in optical cable communication networks for communication and fiber optic transmission. To facilitate the management and maintenance of the optical fibers and patch cords on the fusion splice tray, electronic tags are used at each port to monitor the status of the fiber optic port and patch cord port, and to provide port location guidance. This enables an optical distribution network system that automatically identifies fiber optic connection relationships, calibrates resource information, and provides visual construction guidance.

[0003] The existing electronic tags for the fusion splice trays are located on the tray's cover. When it is necessary to replace fiber optic ports during maintenance, the patch cord port must first be removed from the fusion splice tray, and then the entire cover must be removed to maintain the fiber optic ports and other structures inside the fusion splice tray, making the operation process complicated. Utility Model Content

[0004] This application provides a fusion splice tray, an optical fiber distribution device, a fusion splice tray with an electronic tag, and an optical communication device. The second cover of the fusion splice tray can be flipped open towards the outer front end when the optical fiber port is plugged into a patch cord port, exposing the optical fiber port and improving the convenience of maintenance.

[0005] In a first aspect, a fiber optic fusion splice tray includes a base, a first cover plate, and a second cover plate. The base encloses a receiving space, the top side of which is open, forming an opening in the base. The base includes a front end and a rear end disposed opposite to each other. The front end is provided with a port fixing structure for fixing multiple fiber optic ports, which are used to connect to patch cord ports. The first cover plate is fixedly connected to the base and partially blocks the opening. The first cover plate blocks the rear end and at least a portion of the central area between the rear end and the front end. The second cover plate is connected to the first cover plate and together forms a structure that completely blocks the opening. At least a portion of the second cover plate blocks the port fixing structure. The second cover plate and the first cover plate are movably connected. The connection between the second cover plate and the first cover plate is such that, when the fiber optic port is plugged into the patch cord port, the second cover plate moves away from the first cover plate and the base in a direction outward from the front end, so that the fiber optic port is exposed.

[0006] The second cover of the fusion splice tray provided in this application can be flipped open outwards towards the front end to expose the fiber optic port when a patch cord is plugged into it. Since the second cover only partially obscures the opening, during maintenance, the fiber optic port can be exposed simply by pulling the fusion splice tray out of the frame until the second cover is fully open, without needing to completely remove the base, thus improving maintenance convenience. Because the second cover can be flipped outwards towards the front end, maintenance personnel do not need to disconnect all patch cords and fiber optic ports when performing maintenance on the fiber optic port; they only need to precisely disconnect the patch cord and fiber optic port requiring maintenance, further improving the convenience and accuracy of maintenance.

[0007] In one possible implementation, the connection between the first cover plate and the second cover plate also allows the second cover plate to flip relative to the first cover plate and move away from the base, with the flipping direction of the second cover plate facing the rear end of the base. When the fiber optic port requires maintenance, the second cover plate flips open relative to the base in the direction facing the rear end of the base, and the front end of the second cover plate moves away from the base, exposing the fiber optic port. This solution provides two different flipping methods for the second cover plate, allowing users to choose one method based on their specific usage environment and needs. For example, when the fiber optic port is not connected to any patch cords or has only a few patch cords connected, maintenance does not require the cumbersome step of disconnecting all patch cords and the fiber optic port. In this case, flipping the second cover plate towards the rear end is more convenient. Alternatively, the process of flipping the second cover plate towards the rear end does not affect the connection between all patch cords and the fiber optic port, so the second cover plate can also be flipped towards the rear end.

[0008] In one possible implementation, the second cover plate and the bottom wall of the base are disposed opposite to each other. The second cover plate includes a first electronic tag fixing structure, which is located at the front end of the second cover plate and on the surface of the second cover plate opposite to the bottom wall of the base. The first electronic tag fixing structure is used to fix a first electronic tag such that the first electronic tag faces the side of the second cover plate opposite to the bottom wall of the base. The first electronic tag has information about the optical fiber port.

[0009] The orientation of the first electronic tag is perpendicular to the orientation of the fiber optic port. The first electronic tag is positioned on the surface of the second cover plate away from the bottom wall of the base, rather than on the front surface of the second cover plate. This saves space in the thickness direction of the fusion splice tray, especially when multiple fusion trays are stacked on the frame, which helps to reduce the overall height of the fiber optic distribution device and decrease its space occupation. Furthermore, positioning the first electronic tag on the surface of the second cover plate away from the bottom wall of the base allows for a larger tag area, enabling the reader to scan multiple tags in a single scan, thus improving scanning efficiency.

[0010] In one possible implementation, the first electronic tag fixing structure includes a connecting structure for fixing a second electronic tag fixing structure, the second electronic tag fixing structure being connected to a jumper fiber and used to connect a second electronic tag, the second electronic tag having information about the jumper fiber port.

[0011] With the fiber optic port plugged into the patch cord port, the first electronic tag fixing structure secures the second electronic tag fixing structure via a connecting structure. The first electronic tag within the first electronic tag fixing structure and the second electronic tag within the second electronic tag fixing structure are electrically connected, ensuring information synchronization and association between the fiber optic port and the patch cord port. When the status of the fiber optic port or patch cord port changes (e.g., insertion, removal, or replacement), it can be recorded by both the first and second electronic tags.

[0012] In one possible implementation, the first electronic tag fixing structure includes a first fixing surface and two side surfaces disposed opposite each other at both ends of the first fixing surface. Along the direction from the second cover plate towards the bottom wall of the base, the surface of the first fixing surface opposite to the bottom wall of the base is recessed. The first fixing surface and the two side surfaces enclose a receiving groove for accommodating the first electronic tag. The first electronic tag fixing structure includes two fixing arms, each located on one of the two side surfaces and extending into the receiving groove. The first electronic tag is clamped between the fixing arms and the first fixing surface to fix the first electronic tag. After the first electronic tag is inserted into the first electronic tag fixing structure, the fixing arms contact the surface of the first electronic tag and fix the first electronic tag within the first electronic tag fixing structure.

[0013] In one possible implementation, the connection structure includes a slot. The first electronic tag fixing structure includes a second fixing surface along the direction of the second cover plate toward the bottom wall of the base. The second fixing surface is recessed relative to the first fixing surface to form the slot. The slot is located at one end of the second fixing surface away from the rear edge of the second cover plate. There are two slots, symmetrically arranged along the orientation direction of the optical fiber port. The slot is used to engage with the pins of the second electronic tag fixing structure when the optical fiber port is connected to the jumper port. The pins in the first electronic tag fixing structure and the pins in the second electronic tag fixing structure engage to fix the first electronic tag fixing structure and the second electronic tag fixing structure together. When the first electronic tag is inserted into the first electronic tag fixing structure, the surface of the first electronic tag facing away from the bottom wall abuts against the fixing arm, and the surface of the first electronic tag facing the bottom wall abuts against the first fixing surface. The first electronic tag is sandwiched between the fixing arm and the bottom wall of the first electronic tag fixing structure.

[0014] In one possible implementation, the connection structure includes a third fixing surface and two first inclined surfaces disposed opposite each other at both ends of the third fixing surface. The third fixing surface is located on the side of the first fixing surface facing the bottom wall of the base. The angle between the first inclined surfaces and the third fixing surface is less than 90 degrees. The third fixing surface and the two first inclined surfaces enclose a fixing groove, which is used to accommodate the connecting plate of the second electronic tag fixing structure when the fiber optic port is plugged into the jumper port.

[0015] When the second electronic tag fixing structure is inserted into the first electronic tag fixing structure, the first inclined surface contacts the third inclined surface of the connecting plate. The first and third inclined surfaces cooperate to achieve a fixed connection between the second and first electronic tag fixing structures. The first inclined surface provides a larger contact area with the connecting plate, making the fixed connection between the second and first electronic tag fixing structures more secure. Furthermore, the angle between the first inclined surface and the third fixing surface is less than 90 degrees. The first inclined surface provides support and a limiting effect to the third inclined surface, making the connecting plate more firmly and stably fixed in the fixing groove.

[0016] In one possible implementation, the connecting structure includes two opposing second inclined surfaces connected to the first inclined surface. The second inclined surface is located at the end of the first inclined surface away from the rear end edge of the second cover plate, and the first inclined surface is inclined outwards towards the fixing groove along the orientation direction of the optical fiber port. When the second electronic tag fixing structure is inserted into the first electronic tag fixing structure, the second inclined surface cooperates with the fourth inclined surface of the connecting plate to guide the insertion of the second electronic tag fixing structure into the fixing groove of the first electronic tag fixing structure, facilitating accurate insertion of the connecting plate of the second electronic tag fixing structure into the fixing groove of the first electronic tag fixing structure.

[0017] In one possible implementation, the connection structure includes a positioning groove and a positioning hole. Along the direction of the second cover plate toward the bottom wall of the base, the third fixing surface is recessed relative to the first fixing surface to form the positioning groove. The positioning groove is used to slide relative to the positioning protrusion of the second electronic tag fixing structure when the jumper port is inserted into the optical fiber port. The positioning hole is disposed on the third fixing surface and is located on the side of the positioning groove toward the front edge of the first cover plate. A guide surface is provided at one end of the positioning groove near the positioning hole. The guide surface is used to guide the positioning protrusion from the positioning groove to the positioning hole. The positioning hole is used to accommodate the positioning protrusion when the optical fiber port is inserted into the jumper port.

[0018] The positioning groove and positioning protrusion cooperate to ensure accurate insertion of the second electronic tag fixing structure into the first electronic tag fixing structure without misalignment. The guide surface and positioning protrusion cooperate to facilitate the sliding of the positioning protrusion out of the positioning groove. The positioning hole and positioning protrusion cooperate to securely connect the second and first electronic tag fixing structures after insertion.

[0019] In one possible implementation, the connection states of the first cover plate and the second cover plate include a flattened state and a flipped state. When the first cover plate and the second cover plate are in the flattened state, the second cover plate is connected to the base and together with the first cover plate, they cover the opening. During the process of switching from the flattened state to the flipped state, the connection position of the first cover plate and the second cover plate forms a flipped structure. Through the state change of the flipped structure, the second cover plate flips relative to the first cover plate, and the front end of the second cover plate leaves the base. The flipped structure includes a first part and a second part. The first part is connected to the front edge of the first cover plate and protrudes outward from the front edge of the first cover plate. The second part is disposed inside the second cover plate and adjacent to the rear edge of the second cover plate. The first part includes a support platform and a hook part. The second part includes a locking hole and an abutment part. The support platform is connected between the front edge of the first cover plate and the hook part. The support platform is used to support the rear edge of the second cover plate. The hook part is used to extend into the locking hole and cooperate with the abutment part to realize the connection between the first cover plate and the second cover plate in the flattened state. The flip structure design allows the first cover plate and the second cover plate to switch between flattened and flipped states.

[0020] In one possible implementation, the abutting portion is located between the rear end edge of the second cover plate and the latching hole. In the flattened state, the bottom surface of the abutting portion contacts the support platform, and the side surface of the abutting portion contacts the latching hook portion. In the flipped state, the abutting portion moves away from the support platform and the latching hook portion, and the rear end edge of the second cover plate contacts the support platform.

[0021] In the flattened state, the side of the abutment portion contacts the surface of the hook portion, and the surface of the hook portion limits the abutment portion to prevent the second cover plate from moving relative to the first cover plate after it is connected in the flattened state. In the flipped state, the second cover plate flips relative to the first cover plate, the abutment portion moves away from the support platform and the hook portion, and the rear edge of the second cover plate contacts the support platform, which supports the second cover plate.

[0022] In one possible implementation, the rear end edge of the second cover plate includes a curved surface. During the transition from the flattened state to the flipped state, the curved surface contacts and slides relative to the surface of the support platform. Designing the rear end edge of the second cover plate as a curved surface provides a smoother contact surface, making the flipping of the second cover plate smoother and reducing the risk of jamming during flipping. Furthermore, in the flipped state, the rear end edge of the second cover plate contacts the support platform, and the curved surface provides a larger contact area, making the support platform's support for the second cover plate more stable.

[0023] In one possible implementation, the flipping structure includes a first support plate connected to the front edge of the first cover plate and protruding outward from the front edge of the first cover plate. The first support plate is used to contact a portion of the inner surface of the second cover plate in a flattened state and to support the rear edge of the second cover plate in a flipped state.

[0024] When the first cover plate and the second cover plate are in the flattened state, the second cover plate is connected to the first cover plate and overlaps the first support plate. The surface of the first support plate away from the bottom wall contacts part of the inner surface of the second cover plate to support the second cover plate, improve the fit between the second cover plate and the first support plate, and maintain good rigidity of the first cover plate and the second cover plate in the flattened state.

[0025] When the first cover plate and the second cover plate are in the flipped state, the surface of the first support plate facing away from the bottom wall is used to support the rear end edge of the second cover plate. The first support plate provides stable support for the flipped second cover plate, ensuring the stability of the second cover plate in the flipped state.

[0026] In one possible implementation, the second cover plate includes a base connecting structure facing the first support plate. A limiting portion is formed between the base connecting structure and the rear end edge of the second cover plate on one side of the inner surface of the second cover plate. This limiting portion is used to engage with the first support plate in a flattened state. The base connecting structure has an abutment surface facing the first support plate. The rear end edge of the second cover plate, located between the abutment surface and the front end edge of the first cover plate, forms a limiting portion with the abutment surface. The front end surface of the first support plate contacts the abutment surface, such that the limiting portion engages with the first support plate in a flattened state, limiting the first support plate and preventing the first cover plate from moving relative to the base and the second cover plate.

[0027] In one possible implementation, the base connection structure includes a through hole and a retaining structure. The retaining structure is located between the through hole and the rear end edge of the second cover plate. The retaining structure protrudes relative to the inner surface of the second cover plate, and the limiting portion is formed between the retaining structure and the rear end edge of the second cover plate. The base includes a snap-fit ​​fixing structure. The snap-fit ​​fixing structure passes through the through hole in the flattened state and cooperates with the retaining structure to fix the second cover plate and the base.

[0028] The holding structure has an abutting surface facing the first support plate. The rear edge of the second cover plate, located between the abutting surface and the front edge of the first cover plate, forms a limiting part with the abutting surface. The front surface of the first support plate contacts the abutting surface, so that the limiting part cooperates with the first support plate in the flattened state to limit the first support plate and prevent the first cover plate from moving relative to the base and the second cover plate.

[0029] The snap-fit ​​fixing structure is mounted on the bottom wall of the base and extends protrudes from the bottom wall towards the second cover plate. In its flattened state, the snap-fit ​​fixing structure passes through the through hole and engages with the retaining structure. The surface of the snap-fit ​​fixing structure facing the bottom wall contacts the surface of the retaining structure facing away from the bottom wall. The snap-fit ​​fixing structure applies a force towards the bottom wall to the retaining structure to securely connect the second cover plate and the base. The base and the second cover plate are fixedly connected through the engagement between the base connecting structure and the snap-fit ​​fixing structure.

[0030] In one possible implementation, the front end and the rear end are arranged opposite each other along a first direction. The through hole is elongated, and the length direction of the through hole is a second direction, which is perpendicular to the first direction. The second direction is the direction in which a pair of sidewalls of the base are arranged opposite each other. The length of the through hole is greater than the extension dimension of the snap-fit ​​structure in the second direction. After the snap-fit ​​structure extends into the through hole, the length of the through hole in the second direction is greater than the extension dimension of the snap-fit ​​structure in the second direction. The larger through hole size can accommodate manufacturing tolerances or installation errors. The snap-fit ​​structure can move within the through hole, ensuring that the snap-fit ​​structure can be smoothly inserted into and removed from the through hole without being affected by slight positional deviations.

[0031] In one possible implementation, there are two first support plates, two base connecting structures, at least two first parts, at least two second parts, and two base connecting structures are respectively disposed on both sides of the at least two first parts and the at least two second parts in a second direction. The two first support plates are respectively located on both sides of the at least two first parts and the at least two second parts in a second direction.

[0032] Two base connecting structures are located at both ends of the second cover plate in the second direction, improving the stability of the connection between the second cover plate and the base. The two base connecting structures are respectively disposed on both sides of at least two first parts and at least two second parts in the second direction, and two first support plates are respectively located on both sides of at least two first parts and at least two second parts in the second direction. The at least two first parts and at least two second parts are disposed along the second direction between the two base connecting structures, and between the at least two first parts and at least two second parts in the second direction, ensuring greater stability of the second cover plate in the flattened state and when switching from the flattened state to the flipped state.

[0033] In one possible implementation, the flipping structure includes a second support plate connected to the front edge of the first cover plate and protruding outward from the front edge of the first cover plate. The second support plate is used to contact a portion of the inner surface of the second cover plate in a flattened state and to support the rear edge of the second cover plate in a flipped state. The area of ​​the second support plate is larger than the area of ​​the first support plate and is located at the middle position of the first cover plate extending along a second direction, which is the direction in which a pair of sidewalls of the base are disposed opposite to each other.

[0034] When the first cover plate and the second cover plate are in the flattened state, the second cover plate is connected to the first cover plate and overlaps the second support plate. The surface of the second support plate away from the bottom wall contacts part of the inner surface of the second cover plate to support the second cover plate, thereby improving the fit between the second cover plate and the second support plate and maintaining good rigidity of the first cover plate and the second cover plate in the flattened state.

[0035] When the first and second cover plates are in the flipped state, the surface of the second support plate facing away from the bottom wall is used to support the rear end edge of the second cover plate. The second support plate provides stable support for the flipped second cover plate, ensuring the stability of the second cover plate in the flipped state.

[0036] The second support plate is located at the midpoint of the front edge of the first cover plate in the second direction. Its larger area allows for better support of the second cover plate in both flattened and flipped states, improving the stability between the second and first cover plates. The location of the second support plate at the midpoint of the front edge of the first cover plate in the second direction ensures more balanced force distribution when the second cover plate contacts the second support plate in both flattened and flipped states, reducing the risk of swaying or tilting due to asymmetrical forces. The first and second support plates work together to support the second cover plate, further enhancing the stability between them.

[0037] In one possible implementation, there are two first support plates, and the second support plate is located between the two first support plates. The number of first portions is at least two and is an even number, with half of the first portions located between one of the first support plates and the second support plate, and the other half of the first portions located between the other first support plate and the second support plate.

[0038] Two first support plates are symmetrically arranged on both sides of the second support plate in the second direction. The first and second support plates jointly support the second cover plate in both the flattened and flipped states, making the force on the second cover plate more even.

[0039] The first part is also used to support the second cover plate in the flattened and flipped states. The number of the first part is at least two and is an even number. The first part is symmetrically arranged on both sides of the second support plate in the second direction, which can ensure that the second cover plate is more stable and symmetrical in the flattened state and when switching from the flattened state to the flipped state.

[0040] In one possible implementation, the first cover plate includes two opposing protruding limiting portions located at both ends of the front edge of the first cover plate. The two protruding limiting portions and the front edge of the first cover plate form an enclosing space. The second cover plate has two opposing notches located at both ends of the rear edge of the second cover plate. In the flattened state, the two protruding limiting portions cooperate with the two notches to limit the distance between the first cover plate and the second cover plate. A portion of the second cover plate extends into the enclosing space, and both the flipping structure and the base connecting structure are located within the enclosing space.

[0041] After the two protruding limiting parts are engaged with the two notches, the protruding limiting parts are located between the notches and the side walls of the base. The two protruding limiting parts limit the second cover plate and prevent the second cover plate from moving relative to the first cover plate.

[0042] In the flattened state, part of the second cover plate extends into the enclosing space, placing the flipping structure and the base connection structure within the enclosing space, improving space utilization and making the installation and maintenance of the second cover plate and the first cover plate more convenient and faster.

[0043] Multiple flipping structures are placed within the enclosing space. The design of the flipping structures is more concentrated, and the flipping structures are arranged along the second direction, making the flipping structure approximately a flipping axis along the second direction. The flipping axis serves as the rotation axis for the flipping of the second cover plate. When the second cover plate switches between the flattened state and the flipping state, it can rotate smoothly around this axis, making the flipping of the second cover plate smoother and more stable.

[0044] In one possible implementation, the second cover plate includes a pair of opposing protruding ears, which are located at opposite ends of a second direction at the front end of the second cover plate. The second direction is perpendicular to the first direction and is the direction in which a pair of sidewalls of the base are disposed opposite each other. The pair of protruding ears extend outward relative to the side of the second cover plate. The pair of protruding ears are used to contact a pair of handle structures of the base to achieve connection limiting between the second cover plate and the base. The pair of protruding ears are used to receive external force to cause the second cover plate to leave the base.

[0045] In the flattened state, the protruding ear protrudes from the front end. The surface of the protruding ear facing the rear end contacts the surface of the handle structure facing away from the rear end. The contact between the protruding ear and the handle structure provides a limit between the second cover plate and the base, preventing the second cover plate from moving relative to the base.

[0046] A pair of protruding ears are used to receive external force to detach the second cover from the base. When the fiber fusion tray requires maintenance, the second cover switches between a flattened and flipped state, with the front end of the second cover moving away from the front end of the base. At this time, the maintenance personnel can contact the protruding portion of the ears and apply external force to the ears using this point as a force point, causing the second cover to switch between the flattened and flipped states.

[0047] Secondly, this application provides an optical fiber distribution device, including multiple optical fibers and a fusion splice tray as described in any implementation of the first aspect above, wherein the multiple optical fibers are located within the accommodating space, and the optical fiber ports of the optical fibers are fixed to the port fixing structure.

[0048] The fiber optic distribution device provided in this application includes a fusion splice tray. The second cover of the fusion splice tray can be opened outwards towards the front end when a patch cord is inserted into the fiber optic port, exposing the fiber optic port. Since the second cover only partially obscures the opening, during maintenance, the fiber optic port can be exposed simply by pulling the fusion splice tray out of the frame until the second cover is fully opened, without needing to completely remove the base, thus improving maintenance convenience. Because the second cover can be opened outwards towards the front end, maintenance personnel do not need to disconnect all patch cords and fiber optic ports when performing maintenance on the fiber optic port; they only need to precisely disconnect the patch cord and fiber optic port requiring maintenance, improving both the convenience and accuracy of maintenance.

[0049] Thirdly, this application also provides a fiber optic splice tray with an electronic tag, including an electronic tag and the fiber optic splice tray described in any of the above implementations. The electronic tag is disposed on the second cover plate and corresponds one-to-one with each of the optical fiber ports. The electronic tag on the second cover plate is used to record information of the optical fiber ports.

[0050] Fourthly, this application also provides an optical communication device, including a first electronic tag, a second electronic tag, a jumper, and a fusion splice tray as described in any of the above implementations. The first electronic tag is disposed on the second cover plate and corresponds one-to-one with each of the optical fiber ports. The jumper includes a jumper port and a connecting cord. The jumper port is inserted into the optical fiber port. One end of the connecting cord is sleeved on the jumper, and the other end of the connecting cord has a second electronic tag fixing structure for fixing the second electronic tag. After the jumper is inserted into the optical fiber, the second electronic tag fixing structure on the connecting cord is connected to the first electronic tag fixing structure on the fusion splice tray. The second electronic tag fixed on the second electronic tag fixing structure is electrically connected to the first electronic tag fixed on the first electronic tag fixing structure. The connecting cord is flexible. When the second cover plate is opened to the outward direction of the front end to expose the optical fiber port, the connecting cord bends. Maintenance personnel can open the second cover plate for maintenance while the jumper port is inserted into the optical fiber port without disconnecting all jumper ports and optical fiber ports.

[0070] The embodiments of this application are described below with reference to the accompanying drawings.

[0071] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0072] With the development of fiber optic communication technology, fiber optic transmission is increasingly used in communication systems, thus increasing the difficulty of fiber optic management. A fusion splice tray is a fiber optic connection and distribution device used to connect optical fibers (single fiber optic cores with fiber optic connectors at one end) to patch cords (single fiber optic cores with fiber optic connectors at both ends) or between two patch cords. It is currently widely used in optical cable communication networks for communication and fiber optic transmission. Fusion splice trays are typically mounted on a frame and slidably connected to it. Multiple fusion splice trays are stacked on the frame along its height.

[0073] To facilitate the management and maintenance of optical fibers and patch cords on the fusion splice tray, electronic tags will be used at each port to monitor the status of the optical fiber port and patch cord port, as well as provide port location guidance. This will enable an optical distribution network system that automatically identifies optical fiber connection relationships, calibrates resource information, and provides visual construction guidance.

[0074] The existing fusion splice trays use electronic tags on their covers to record and manage the connections between fiber optic ports and patch cords. If a fiber optic port needs to be replaced during maintenance, the patch cord must first be removed from the fusion splice tray, then the entire cover must be removed to maintain the fiber optic ports and other structures inside the tray. After maintenance, the patch cord must be reinserted into the fusion splice tray, making the process complex. Furthermore, removing the cover requires pulling the fusion splice tray, mounted on the fiber optic patch panel, out at least two-thirds of its length. With patch cords connected, it's difficult to pull the fusion splice tray out this much for repairs.

[0075] To address the aforementioned problems, this application provides a fusion splice tray 100, primarily used for splicing, connecting, and storing optical fibers. It can be applied in an optical fiber distribution device 10, which includes, but is not limited to, an optical distribution frame (ODF), an optical branch device (OBD), and an optical cross-connect cabinet (OCC). This application also provides a fusion splice tray with electronic tags and an optical fiber distribution structure with electronic tags. Electronic tags are fixed to the fusion splice tray to record information for each optical fiber port. This application further provides an optical communication device, which includes a fusion splice tray with electronic tags or an optical fiber distribution structure with electronic tags. This application also provides an optical communication device, which includes patch cords and a fusion splice tray with electronic tags or an optical fiber distribution structure with electronic tags.

[0076] See Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the fusion splice tray 100 includes a base 110, a first cover plate 120, and a second cover plate 130. Each wall of the base 110 forms a receiving space 111 for accommodating the optical fiber 200. The top side of the receiving space 111 is open, forming an opening 112 of the base 110. The top side of the receiving space 111 is one side of the receiving space 111 in the positive Z direction. The base 110 includes a front end 113 and a rear end 114 disposed opposite to each other. In this application, the front end 113 and the rear end 114 are disposed opposite to each other along a first direction, which is the X direction. The front end 113 is one end of the base 110 in the positive X direction, and the rear end 114 is one end of the base 110 in the opposite X direction. The length direction of the fusion splice tray 100 is a second direction, perpendicular to the first direction, and is the Y direction. The height direction of the fusion splice tray 100 is a third direction, which is the Z direction. The front end 113 is provided with a port fixing structure 140, which is used to fix multiple fiber optic ports 210. The fiber optic ports 210 are used to connect to patch cord ports 310. When the fiber optic cable 200 is located within the receiving space 111, the fiber optic ports 210 of the fiber optic cable 200 are fixed on the port fixing structure 140. When the patch cord 300 outside the fusion splice tray 100 is plugged into the fiber optic cable 200, the patch cord port 310 is connected to the fiber optic port 210 to realize the transmission of optical signals.

[0077] In this application, "multiple" refers to a quantity of two or more. The number of port fixing structures 140 can be multiple, and these multiple port fixing structures 140 are arranged at intervals along the Y direction at the front end 113. The multiple port fixing structures 140 are used to fix multiple fiber optic ports 210, with each port fixing structure 140 fixing one fiber optic port 210. In one embodiment, the port fixing structure 140 is provided with threads, and the port fixing structure 140 is fixedly connected to the fiber optic port 210 by a threaded connection.

[0078] After the port fixing structure 140 fixes the fiber optic port 210, the connector of the fiber optic port 210 faces the side of the port fixing structure 140 away from the rear end 114. In one embodiment, the connector of the fiber optic port 210 is aligned with or parallel to the positive X direction, and the connector of the fiber optic port 210 faces directly in front of the front end 113. In some other embodiments, such as... Figure 3 As shown, the direction of the fiber optic port 210 can also be at an angle to the X direction, increasing the space utilization efficiency of the front end 113 and allowing for more port fixing structures 140 to be set.

[0079] The first cover plate 120 and the base 110 are fixedly connected and partially block the opening 112. The first cover plate 120 blocks the rear end 114 and at least a portion of the central region between the rear end 114 and the front end 113. The second cover plate 130 is connected to the first cover plate 120 and together forms a structure that completely blocks the opening 112. The first cover plate 120 and the second cover plate 130 together block the opening 112, protecting the optical fiber 200 located in the receiving space 111. At least a portion of the second cover plate 130 blocks the port fixing structure 140. When the second cover plate 130 and the base 110 are connected and partially block the opening 112, the front end of the second cover plate 130 blocks the port fixing structure 140, protecting the port fixing structure 140.

[0080] The second cover plate 130 and the first cover plate 120 are movably connected. The connection between the second cover plate 130 and the first cover plate 120 allows the fiber optic port 210 to be exposed when it is plugged into the patch cord port 310, and it is positioned away from the first cover plate 120 and the base 110 in the outward direction towards the front end 113. In one embodiment, along the X direction, the area of ​​the opening 112 partially covered by the first cover plate 120 is larger than the area of ​​the opening 112 partially covered by the second cover plate 130. For example, the first cover plate 120 covers two-thirds of the opening 112, while the second cover plate 130 only covers one-third of the opening 112. Thus, when maintenance of the fiber optic port is required, only the second cover plate 130 needs to be opened, without needing to open the first cover plate 120. Since the second cover plate 130 has a smaller area and is lighter, it is easier to open.

[0081] Specifically, the connection between the second cover plate 130 and the first cover plate 120 is broken, and the second cover plate 130 is flipped outward toward the front end 113 to form a shape as shown in the figure. Figure 4 In the state shown, the second cover plate 130 is completely separated from the first cover plate 120 and the base 110, and is not connected to them. When the fiber optic port 210 requires maintenance, the second cover plate 130 can be opened with the fiber optic port 210 connected to the patch cord port 310, exposing the fiber optic port 210. Maintenance personnel do not need to disconnect all patch cord ports 310 and the fiber optic port 210 during maintenance; they only need to precisely disconnect the patch cord port 310 and the fiber optic port 210 requiring maintenance, improving the convenience and accuracy of maintenance. Furthermore, during maintenance, the fiber optic port 210 can be exposed simply by pulling the fusion splice tray 100 out of the frame to fully open the second cover plate 130, further enhancing maintenance convenience.

[0082] In one embodiment, the length of the first cover plate 120 in the X direction is greater than the length of the second cover plate 130 in the X direction. When maintaining the fiber optic port 210, the length of the second cover plate 130 in the X direction is smaller, and when the fusion splice tray 100 is pulled out from the fiber optic patch panel, the distance that the fusion splice tray 100 moves relative to the distance from the fiber optic patch panel is also smaller, which facilitates the maintenance of the fiber optic port 210.

[0083] This application provides a second cover 130 of a fusion splice tray 100 that can be opened outwards toward the front end 113 to expose the fiber optic port 210 when a patch cord port 310 is plugged into the fiber optic port 210. Since the second cover 130 only partially obscures the opening 112, during maintenance, the fiber optic port 210 can be exposed simply by pulling the fusion splice tray 100 out of the frame until the second cover 130 is fully opened, without needing to completely remove the base 110, thus improving maintenance convenience. Because the second cover 130 can be opened outwards toward the front end 113, when maintenance personnel perform maintenance on the fiber optic port 210, it is not necessary to disconnect all patch cord ports 310 and fiber optic ports 210; only the patch cord port 310 and fiber optic port 210 requiring maintenance need to be precisely disconnected for repair, improving both the convenience and accuracy of maintenance.

[0084] In one possible implementation, the connection between the first cover plate 120 and the second cover plate 130 also enables the second cover plate 130 to be flipped relative to the first cover plate 120 and away from the base 110, with the flipping direction of the second cover plate 130 being toward the rear end 114 of the base 110.

[0085] Specifically, the second cover plate 130 remains connected to the first cover plate 120. The second cover plate 130 rotates about its connection point with the first cover plate 120, rotating in a direction toward the rear end 114 of the base 110, forming a shape as shown. Figure 5In the state shown, the second cover plate 130 is still connected to the first cover plate 120, and the front end of the second cover plate 130 is away from the base 110. When the fiber optic port 210 needs maintenance, the second cover plate 130 is flipped open relative to the base 110 in the direction towards the rear end 114 of the base 110, and the front end of the second cover plate 130 is away from the base 110, exposing the fiber optic port 210. This solution provides two different flipping methods for the second cover plate 130. One of the flipping methods can be selected according to the specific usage environment and needs. For example, when the fiber optic port 210 is not connected to the patch cord port 310 or is connected to a small number of patch cord ports 310, there is no need to disconnect all patch cord ports 310 and the fiber optic port 210 during maintenance. In this case, flipping the second cover plate 130 towards the rear end 114 is more convenient to operate. Alternatively, when the second cover 130 is flipped open to the rear end, it does not affect the connection between all jumper ports 310 and fiber optic ports 210, and the second cover 130 can be flipped open towards the rear end 114.

[0086] In one possible implementation, see [reference] Figure 2 and Figure 3 As shown, the base 110 includes a bottom wall 115, and a second cover plate 130 is disposed opposite to the bottom wall 115 of the base 110, with the second cover plate 130 and the bottom wall 115 disposed opposite to each other along the Z direction. The second cover plate 130 includes a first electronic tag fixing structure 131, which is located at the front end of the second cover plate 130 and on the surface 132 of the second cover plate 130 facing away from the bottom wall 115 of the base 110. The first electronic tag fixing structure 131 is used to fix a first electronic tag 150 such that the first electronic tag 150 faces the side of the second cover plate 130 facing away from the bottom wall 115 of the base 110. Each first electronic tag 150 corresponds one-to-one with each fiber optic port 210, and the first electronic tag 150 contains information about the fiber optic port 210. The first electronic tag 150 may record information such as the identification number (ID) or type of the fiber optic port 210.

[0087] In this embodiment of the application, the first electronic tag 150 may be a radio frequency identification (RFID) electronic tag. The reader uses radio frequency to read and write the electronic tag and obtain the information of the fiber optic port 210 recorded by the first electronic tag 150.

[0088] In this embodiment, the front end of the second cover plate 130 is one end of the second cover plate 130 in the positive X direction, and the surface 132 of the second cover plate 130 facing away from the bottom wall 115 of the base 110 is the surface 132 of the second cover plate 130 in the positive Z direction. The first electronic tag 150 faces the Z direction and is perpendicular to the insertion direction of the fiber optic port 210. The first electronic tag 150 is disposed on the surface 132 of the second cover plate 130 in the positive Z direction, rather than on the front end of the second cover plate 130. This saves space in the thickness direction of the fiber optic fusion tray 100, especially when multiple fiber optic fusion trays 100 are stacked on the frame 400, which helps to reduce the overall height of the fiber optic distribution device 10 and decrease the space occupied by the fiber optic distribution device 10. Furthermore, since the first electronic tag 150 is disposed on the surface 132 of the second cover plate 130 in the positive Z direction, the area of ​​the first electronic tag 150 can be set to be larger, which is beneficial for the reader to scan multiple first electronic tags 150 in one scan, improving scanning efficiency.

[0089] In one possible implementation, see [reference] Figure 3 and Figure 6A As shown, the first electronic tag fixing structure 131 includes a first fixing surface 131a and two side surfaces 131b opposite to each other at both ends of the first fixing surface 131a. The two side surfaces 131b are opposite to each other at both ends of the first fixing surface 131a along a direction perpendicular to the optical fiber port 210. Along the direction from the second cover plate 130 toward the bottom wall 115 of the base 110, the surface 132 of the first fixing surface 131a is recessed relative to the side of the second cover plate 130 facing away from the bottom wall 115 of the base 110. The first fixing surface 131a and the surface 132 of the second cover plate 130 facing away from the bottom wall 115 of the base 110 are parallel in the Z direction, and the first fixing surface 131a is located on the side of the second cover plate 130 facing away from the bottom wall 115 of the base 110 in the opposite Z direction. The first fixing surface 131a and the two side surfaces 131b form a receiving groove 1311, which is used to receive the first electronic tag 150. The first electronic tag fixing structure 131 includes two fixing arms 1312, which are located on two side surfaces 131b and extend into the receiving groove 1311. When the first electronic tag 150 is inserted into the first electronic tag fixing structure 131, the surface of the first electronic tag 150 facing away from the bottom wall 115 abuts against the fixing arm 1312, and the surface of the first electronic tag 150 facing the bottom wall 115 abuts against the first fixing surface 131a. The first electronic tag 150 is clamped between the fixing arm 1312 and the bottom wall of the first electronic tag fixing structure 131 to fix the first electronic tag 150. After the first electronic tag 150 is fixed in the first electronic tag fixing structure 131, it is arranged parallel to the second cover plate 130 in the Z direction.

[0090] In one possible implementation, see [reference] Figure 3 and Figure 6A As shown, the first electronic tag fixing structure 131 includes a connecting structure, which can be disposed inside or outside the first electronic tag fixing structure 131. The connecting structure is used to fix the second electronic tag fixing structure 510. The second electronic tag fixing structure 510 is connected to the jumper 300 and is used to connect the second electronic tag 520, which has information about the jumper port 310. When the fiber optic port 210 is plugged into the jumper port 310, the first electronic tag fixing structure 131 fixes the second electronic tag fixing structure 510 through the connecting structure. The first electronic tag 150 in the first electronic tag fixing structure 131 and the second electronic tag 520 in the second electronic tag fixing structure 510 are electrically connected to ensure information synchronization and association between the fiber optic port 210 and the jumper port 310. When the state of the fiber optic port 210 or the jumper port 310 changes (e.g., insertion, removal, or replacement), it can be recorded by the first electronic tag 150 and the second electronic tag 520.

[0091] In one embodiment, a connector is also housed within the first electronic tag fixing structure 131, and the first electronic tag 150 and the second electronic tag 520 are electrically connected through the connector.

[0092] The second electronic tag 520 may record information such as the identification number (ID) of the jumper port 310 or the type of the jumper port 310. In this embodiment, the second electronic tag 520 may be a radio frequency identification (RFID) electronic tag, and the reader uses radio frequency to read and write to the electronic tag to obtain the information of the jumper port 310 recorded by the second electronic tag 520.

[0093] In one possible implementation, see [reference] Figure 3 and Figure 6AAs shown, the first electronic tag fixing structure 131 includes a second fixing surface 131c, which is parallel to the first fixing surface 131a along the Z direction. The second fixing surface 131c is located on the side of the first fixing surface 131a opposite to the Z direction. Along the direction from the second cover plate 130 toward the bottom wall 115 of the base 110, the second fixing surface 131c is recessed relative to the first fixing surface 131a to form a slot 1313. The slot 1313 is located at one end of the second fixing surface 131c away from the rear edge 133 of the second cover plate 130. There are two slots 1313, which are symmetrically arranged along the orientation direction of the fiber optic port 210 to improve the stability of the connection with the second electronic tag fixing structure 510. The second electronic tag fixing structure 510 includes two pins 411. When the fiber optic port 210 is plugged into the jumper port 310, the slot 1313 in the first electronic tag fixing structure 131 and the pin 411 in the second electronic tag fixing structure 510 are plugged in to fix the first electronic tag fixing structure 131 and the second electronic tag fixing structure 510.

[0094] Understandably, in one embodiment, the slots 1313 on the first electronic tag fixing structure 131 and the second electronic tag fixing structure 510 can be interchanged. When the fiber optic port 210 is plugged into the jumper port 310, the pins 411 in the first electronic tag fixing structure 131 and the pins 411 in the second electronic tag fixing structure 510 are plugged in to fix the first electronic tag fixing structure 131 and the second electronic tag fixing structure 510.

[0095] In one possible implementation, see [reference] Figure 6B and Figure 6C As shown, the connection structure includes a third fixing surface 131d and two first inclined surfaces 1314 disposed opposite each other at both ends of the third fixing surface 131d. The two first inclined surfaces 1314 are disposed opposite each other at both ends of the third fixing surface 131d along a direction perpendicular to the optical fiber port 210. The third fixing surface 131d is located on the side of the first fixing surface 131a facing the bottom wall 115 of the base 110. The third fixing surface 131d is parallel to the first fixing surface 131a and is located on the side of the first fixing surface 131a in the opposite direction of Z. The angle between the first inclined surfaces 1314 and the third fixing surface 131d is less than 90 degrees. The third fixing surface 131d and the two first inclined surfaces 1314 enclose a fixing groove 1315, which is used to accommodate the connecting plate 412 of the second electronic tag fixing structure 510 when the optical fiber port 210 is plugged into the jumper port 310. The connecting plate 412 is located in the fixing groove 1315 to achieve a fixed connection between the second electronic tag fixing structure 510 and the first electronic tag fixing structure 131.

[0096] The connecting plate 412 includes two third inclined surfaces 413 arranged opposite each other along a direction perpendicular to the optical fiber port 210. The shapes of the third inclined surfaces 413 and the first inclined surface 1314 match. When the second electronic tag fixing structure 510 and the first electronic tag fixing structure 131 are inserted, the first inclined surface 1314 contacts the third inclined surface 413 of the connecting plate 412. The cooperation of the first inclined surface 1314 and the third inclined surface 413 achieves a fixed connection between the second electronic tag fixing structure 510 and the first electronic tag fixing structure 131. The first inclined surface 1314 provides a larger contact area with the connecting plate 412, making the fixed connection between the second electronic tag fixing structure 510 and the first electronic tag fixing structure 131 more secure. Furthermore, the angle between the first inclined surface 1314 and the third fixing surface 131d is less than 90 degrees. The first inclined surface 1314 provides support and a limiting effect on the third inclined surface 413, making the connecting plate 412 more securely and stably fixed within the fixing groove 1315.

[0097] In one possible implementation, see [reference] Figure 6B and Figure 6C As shown, the connection structure includes two opposing second inclined surfaces 1316, which are arranged in a direction perpendicular to the fiber optic port 210. The second inclined surfaces 1316 are connected to the first inclined surface 1314, and are located at the end of the first inclined surface 1314 away from the rear end edge 133 of the second cover plate 130, and at the front end of the first electronic tag fixing structure 131. The first inclined surface 1314 is inclined outwards towards the fixing groove 1315 along the direction of the fiber optic port 210. The connecting plate 412 of the second electronic tag fixing structure 510 includes two opposing fourth inclined surfaces 414 arranged in a direction perpendicular to the direction of the fiber optic port 210. The shapes of the fourth inclined surfaces 414 match those of the second inclined surfaces 1316.

[0098] When the second electronic tag fixing structure 510 is inserted into the first electronic tag fixing structure 131, the second inclined surface 1316 contacts the fourth inclined surface 414 of the connecting plate 412. Along the insertion direction of the fiber optic port 210 and the jumper port 310, the second inclined surface 1316 is inclined towards the outside of the fixing groove 1315. The second inclined surface 1316 and the fourth inclined surface 414 cooperate to guide the second electronic tag fixing structure 510 and the first electronic tag fixing structure 131 during insertion, so that the connecting plate 412 of the second electronic tag fixing structure 510 can be accurately inserted into the fixing groove 1315 of the first electronic tag fixing structure 131.

[0099] In one possible implementation, see [reference] Figure 6B and Figure 6CAs shown, the connection structure includes a positioning groove 1317 and a positioning hole 1318. Along the direction from the second cover plate 130 toward the bottom wall 115 of the base 110, the third fixing surface 131d is recessed relative to the first fixing surface 131a to form the positioning groove 1317, with the opening of the positioning groove 1317 facing the bottom wall 115. The positioning hole 1318 is disposed on the third fixing surface 131d, with its opening facing the bottom wall 115. The positioning hole 1318 is located on the side of the positioning groove 1317 facing the front edge 121 of the first cover plate 120. A guide surface 1319 is provided at one end of the positioning groove 1317 near the positioning hole 1318. The positioning hole 1318 and the positioning groove 1317 are spaced apart along the orientation direction of the fiber optic port 210. The positioning groove 1317 is used to slide relative to the positioning protrusion 415 of the second electronic tag fixing structure 510 when the jumper port 310 is plugged into the fiber optic port 210. When the positioning protrusion 415 slides into the positioning groove 1317 to the guide surface 1319, the guide surface 1319 guides the positioning protrusion 415 from the positioning groove 1317 to the positioning hole 1318. After sliding out of the positioning groove 1317, the positioning protrusion 415 enters the positioning hole 1318. The positioning hole 1318 is used to accommodate the positioning protrusion 415 when the fiber optic port 210 is plugged into the jumper port 310. The positioning protrusion 415 and the positioning hole 1318 have the same size. After the positioning protrusion 415 is located in the positioning hole 1318, it can be fixed and limited by the positioning hole 1318. The positioning hole 1318 can be a through hole or a blind hole. In this embodiment, the positioning hole is a through hole, penetrating the first fixing surface 131a and the third fixing surface 131d.

[0100] The positioning groove 1317, guide surface 1319, positioning hole 1318, and positioning protrusion 415 work together to accurately fix the first electronic tag fixing structure 131 and the second electronic tag fixing structure 510. The positioning groove 1317 and positioning protrusion 415 ensure accurate insertion of the second electronic tag fixing structure 510 into the first electronic tag fixing structure 131 without misalignment. The guide surface 1319 and positioning protrusion 415 facilitate the sliding of the positioning protrusion 415 out of the positioning groove 1317. The positioning hole 1318 and positioning protrusion 415 fix the second electronic tag fixing structure 510 and the first electronic tag fixing structure 131 after insertion.

[0101] In one embodiment, the connecting plate 412 is elastic. When the second electronic tag fixing structure 510 is inserted into the first electronic tag fixing structure 131, the positioning protrusion 415 slides in the positioning groove 1317. Subsequently, after the positioning protrusion 415 slides out of the positioning groove 1317, it contacts the third fixing surface 131d, causing the connecting plate 412 to undergo elastic deformation. When the positioning protrusion 415 enters the positioning hole 1318, the elastic deformation of the connecting plate 412 disappears, and the connecting plate 412 emits a sound indicating that the positioning protrusion 415 is located in the positioning hole 1318. The second electronic tag fixing structure 510 and the first electronic tag fixing structure 131 are accurately fixedly connected. In one possible implementation, the connection state of the first cover plate 120 and the second cover plate 130 includes a flattened state and a flipped state, see reference. Figure 1 As shown, when the first cover plate 120 and the second cover plate 130 are in a flattened state, the second cover plate 130 is connected to the base 110 and together with the first cover plate 120, it covers the opening 112. Figure 5 The first cover plate 120 and the second cover plate 130 shown are in a flipped state. During the transition from the flattened state to the flipped state, the connection point of the first cover plate 120 and the second cover plate 130 forms a flipping structure 160. Through the change in the state of the flipping structure 160, the second cover plate 130 flips relative to the first cover plate 120, and the front end of the second cover plate 130 moves away from the base 110. The design of the flipping structure 160 allows the first cover plate 120 and the second cover plate 130 to switch between the flattened state and the flipped state.

[0102] Specifically, see Figure 7 and Figure 8As shown, the flip structure 160 includes a first part 161 and a second part 162. The first part 161 is connected to the front edge 121 of the first cover plate 120 and protrudes outward from the front edge 121 of the first cover plate 120. The first part 161 includes a support platform 1611 and a hook portion 1612. The support platform 1611 extends protrudingly from the front edge 121 of the first cover plate 120 in the positive X direction and connects between the front edge 121 of the first cover plate 120 and the hook portion 1612. The support platform 1611 is used to support the rear edge 133 of the second cover plate 130. The hook portion 1612 extends from one end of the support platform 1611 away from the front edge of the first cover plate 120 in the positive Z direction. In one embodiment, the support platform 1611 and the hook portion 1612 are integrally formed to form the first part 161. The second part 162 is disposed within the second cover plate 130 and adjacent to the rear end edge 133 of the second cover plate 130. The second part 162 includes a locking hole 1621 and an abutment portion 1622, with the abutment portion 1622 located between the locking hole 1621 and the rear end edge 133 of the second cover plate 130. When the first cover plate 120 and the second cover plate 130 are in a flattened state, the hook portion 1612 is used to extend into the locking hole 1621 and engage with the abutment portion 1622 to achieve a connection between the first cover plate 120 and the second cover plate 130 in the flattened state.

[0103] In one possible implementation, see [reference] Figure 7 and Figure 8 As shown, the abutment portion 1622 is located between the rear end edge 133 of the second cover plate 130 and the locking hole 1621. The front end edge 121 of the first cover plate 120, the support platform 1611, and the locking hook portion 1612 enclose a space for accommodating the abutment portion 1622. In the flattened state, the bottom surface 1622a of the abutment portion 1622 contacts the support platform 1611, and the side surface 1622b of the abutment portion 1622 contacts the locking hook portion 1612.

[0104] In this embodiment, the bottom surface 1622a of the abutment portion 1622 is the surface of the abutment portion 1622 on the opposite side of the Z direction, and the side surface 1622b of the abutment portion 1622 is the surface of the abutment portion 1622 on the positive side of the X direction. In the flattened state, the bottom surface 1622a of the abutment portion 1622 contacts the surface of the support platform 1611 on the positive side of the Z direction, so that the support platform 1611 can support the rear end edge 133 of the second cover plate 130. In one embodiment, the shapes of the bottom surface of the abutment portion 1622 and the surface of the support platform 1611 on the positive side of the Z direction are matched so that the bottom surface of the abutment portion 1622 and the surface of the support platform 1611 on the positive side of the Z direction can fit completely together when they contact each other, thereby improving the support effect of the support platform 1611 on the second cover plate 130.

[0105] In the flattened state, refer to Figure 8As shown, the side surface 1622b of the abutment portion 1622 and the hook portion 1612 are in contact on the surface of the opposite X direction. The surface of the hook portion 1612 on the opposite X direction limits the abutment portion 1622 to prevent the second cover plate 130 from moving relative to the first cover plate 120 in the positive X direction after it is flattened and connected to the first cover plate 120.

[0106] In the flipped state, see [link / reference] Figure 9 As shown, the second cover plate 130 is flipped relative to the first cover plate 120, the abutting part 1622 leaves the support platform 1611 and the hook part 1612, and the rear edge 133 of the second cover plate 130 contacts the support platform 1611, and the support platform 1611 supports the second cover plate 130.

[0107] In one embodiment, the hook portion 1612 is elastic. When the elastic hook portion 1612 is inserted into the card hole 1621 and comes into contact with the side 1622b of the abutment portion 1622, the hook portion 1612 and the abutment portion 1622 are deformed. The deformation enables a tighter fit between the hook portion 1612 and the abutment portion 1622, ensuring that the first cover plate and the second cover plate will not easily separate in the flattened state.

[0108] In one embodiment, see [reference] Figure 8 As shown, the hook portion 1612 also includes a protrusion 1612a, which is located at the end of the hook portion 1612 away from the support platform 1611 and extends toward the front edge 121 of the first cover plate 120. The protrusion 1612a can limit the abutment portion 1622 to prevent the second cover plate 130 from separating from the first cover plate 120.

[0109] In one embodiment, see [reference] Figure 10 As shown, a through hole 1611a is provided on the support platform 1611, and the through hole 1611a penetrates the support platform 1611 along the Z direction. The through hole 1611a can reduce the weight of the support platform 1611, thereby reducing the weight of the fiber fusion tray 100.

[0110] In one possible implementation, the rear end edge 133 of the second cover plate 130 includes an arcuate surface. During the transition from the flattened state to the flipped state, the arcuate surface contacts and slides relative to the surface of the support platform 1611. The arcuate surface design of the rear end edge 133 of the second cover plate 130 provides a smoother contact surface, making the flipping of the second cover plate 130 smoother and reducing the risk of jamming during the flipping process. Furthermore, in the flipped state, the rear end edge 133 of the second cover plate 130 contacts the support platform 1611, and the arcuate surface provides a larger contact area, making the support platform 1611's support of the second cover plate 130 more stable.

[0111] In one embodiment, see Figure 8 and Figure 9As shown, the surface of the support platform 1611 connected to the front edge 121 of the first cover plate 120 in the positive Z direction is also an arc-shaped surface. During the transition from the flattened state to the flipped state, the arc-shaped surface and the surface of the support platform 1611 connected to the front edge 121 of the first cover plate 120 in the positive Z direction are in contact and slide relative to each other.

[0112] In one embodiment, the front edge 121 of the first cover plate 120 also includes an arcuate surface. The front edge 121 of the first cover plate 120 and the rear edge 133 of the second cover plate 130 are both designed as arcuate surfaces, making the process of the second cover plate 130 switching from a flattened state to a flipped state smoother.

[0113] In one possible implementation, see [reference] Figure 7 and Figure 11 As shown, the flip structure 160 includes a first support plate 163, which is connected to the front edge 121 of the first cover plate 120 and protrudes outward from the front edge 121 of the first cover plate 120. The first support plate 163 extends from the front edge 121 of the first cover plate 120 in the X direction and protrudes outward from the front edge 121 of the first cover plate 120. The first support plate 163 is used to contact a portion of the inner surface 134 of the second cover plate 130 in the flattened state and to support the rear edge 133 of the second cover plate 130 in the flipped state.

[0114] In this embodiment of the application, the inner surface 134 of the second cover plate 130 is the surface of the second cover plate 130 on the Z-reverse side.

[0115] When the first cover plate 120 and the second cover plate 130 are in a flattened state, refer to Figure 11 As shown, the second cover plate 130 is connected to the first cover plate 120. The second cover plate 130 overlaps the first support plate 163. The surface of the first support plate 163 facing away from the bottom wall 115 contacts a portion of the inner surface 134 of the second cover plate 130 to support the second cover plate 130, improve the fit between the second cover plate 130 and the first support plate 163, and ensure that the first cover plate 120 and the second cover plate 130 maintain good rigidity in the flattened state.

[0116] When the first cover plate 120 and the second cover plate 130 are in the flipped state, refer to Figure 12 As shown, the front end of the second cover plate 130 is separated from the base 110, and the rear end of the second cover plate 130 is connected to the first cover plate 120 and inclined relative to the first cover plate 120. After the second cover plate 130 is flipped, the surface of the first support plate 163 facing away from the bottom wall 115 is used to support the rear edge 133 of the second cover plate 130. The first support plate 163 provides stable support for the flipped second cover plate 130, ensuring the stability of the second cover plate 130 in the flipped state.

[0117] In one possible implementation, see [reference] Figure 11 and Figure 13 As shown, the second cover plate 130 includes a base connecting structure 135, which is disposed near the rear end edge 133 of the second cover plate 130 and extends toward the bottom wall 115. The base connecting structure 135 faces the first support plate 163, and when the first cover plate 120 and the second cover plate 130 are in a flattened state, the base connecting structure 135 faces the first support plate 163 in the X direction. On one side of the inner surface 134 of the second cover plate 130, a limiting portion 1354 is formed between the base connecting structure 135 and the rear end edge 133 of the second cover plate 130, which is used to cooperate with the first support plate 163 in the flattened state.

[0118] The base connection structure 135 has an abutment surface 1351, which faces the first support plate 163 in the X direction. The rear edge 133 of the second cover plate 130, located between the abutment surface 1351 and the front edge 121 of the first cover plate 120, forms a limiting part 1354 with the abutment surface 1351. The front surface 1631 of the first support plate 163 contacts the abutment surface 1351, so that the limiting part 1354 cooperates with the first support plate 163 in the flattened state to limit the first support plate 163 and prevent the first cover plate 120 from moving relative to the base 110 and the second cover plate 130 in the X direction.

[0119] In one possible implementation, see [reference] Figure 11 , Figure 13 and Figure 14 As shown, the base connecting structure 135 includes a through hole 1352 and a retaining structure 1353. The through hole 1352 penetrates the second cover plate 130 of the base along the Z direction. The retaining structure 1353 is located between the through hole 1352 and the rear end edge 133 of the second cover plate 130. The retaining structure 1353 protrudes relative to the inner surface of the second cover plate 130 and protrudes towards the bottom wall 115, forming a limiting part 1354 between the retaining structure 1353 and the rear end edge 133 of the second cover plate 130. The retaining structure 1353 has an abutment surface 1351, which faces the first support plate 163 along the X direction. The rear edge 133 of the second cover plate 130, located between the abutment surface 1351 and the front edge 121 of the first cover plate 120, forms a limiting part 1354 with the abutment surface 1351. The front surface 1631 of the first support plate 163 contacts the abutment surface 1351, so that the limiting part 1354 cooperates with the first support plate 163 in the flattened state to limit the first support plate 163, preventing the first cover plate 120 from moving relative to the base 110 and the second cover plate 130 in the X direction.

[0120] The base 110 includes a snap-fit ​​fixing structure 116, which is disposed on the bottom wall 115 of the base 110 and extends from the bottom wall 115 towards the second cover plate 130, protruding from the bottom wall 115. In its flattened state, the snap-fit ​​fixing structure 116 passes through the through hole 1352 and engages with the retaining structure 1353. The surface of the snap-fit ​​fixing structure 116 facing the bottom wall 115 contacts the surface of the retaining structure 1353 facing away from the bottom wall 115. The snap-fit ​​fixing structure 116 applies a force to the retaining structure 1353 in the direction of the bottom wall 115 to securely connect the second cover plate 130 and the base 110. The base 110 and the second cover plate 130 are securely connected through the engagement between the base connecting structure 135 and the snap-fit ​​fixing structure 116.

[0121] In one possible implementation, see [reference] Figure 14 As shown, the front end 113 and the rear end 114 are arranged opposite each other along the first direction. The through hole 1352 is elongated and the length direction of the through hole 1352 is the second direction, which is perpendicular to the first direction. The second direction is the direction in which the pair of side walls 117 of the base 110 are arranged opposite each other. The length dimension of the through hole 1352 is greater than the dimension of the buckle fixing structure 116 extending in the second direction.

[0122] In this embodiment, the second direction is the Y direction. The base 110 has three sidewalls 117, two of which are arranged opposite each other along the Y direction, and the other sidewall 117 is located at the rear end 114. After the snap-fit ​​fixing structure 116 extends into the through hole 1352, the length dimension of the through hole 1352 in the Y direction is greater than the extension dimension of the snap-fit ​​fixing structure 116 in the Y direction. The larger size of the through hole 1352 can accommodate manufacturing tolerances or installation errors. The snap-fit ​​fixing structure 116 can move within the through hole 1352, ensuring that the snap-fit ​​fixing structure 116 can be smoothly inserted into and removed from the through hole 1352 without being affected by slight positional deviations.

[0123] In one possible implementation, see [reference] Figure 7 and Figure 11 As shown, there are two first support plates 163 and two base connecting structures 135. The two first support plates 163 are arranged opposite each other along the Y direction, and the two base connecting structures 135 are arranged opposite each other along the Y direction. Each first support plate 163 corresponds to each base connecting structure 135.

[0124] The number of first parts 161 is at least two, and the number of second parts 162 is at least two. The number of first parts 161 and second parts 162 is equal, and there is a one-to-one correspondence between each first part 161 and each second part 162. The number of first parts 161 and second parts 162 can be two, three, four, or so on. The cooperation between at least two first parts 161 and at least two second parts 162 makes it easier for the second cover plate 130 to flip relative to the first cover plate 120.

[0125] Two first support plates 163 are located at both ends of the first cover plate 120 in the Y direction. The first support plates 163 support both ends of the rear end edge 133 of the second cover plate 130, improving the stability of the second cover plate 130 in both flattened and flipped states. Two base connecting structures 135 are located at both ends of the second cover plate 130 in the Y direction, improving the stability of the connection between the second cover plate 130 and the base 110. The two base connecting structures 135 are respectively disposed on both sides of at least two first parts 161 and at least two second parts 162 in the second direction, and the two first support plates 163 are respectively disposed on both sides of at least two first parts 161 and at least two second parts 162 in the second direction. The at least two first parts 161 and at least two second parts 162 are disposed along the Y direction between the two base connecting structures 135, and the at least two first parts 161 and at least two second parts 162 are disposed along the Y direction between the two first support plates 163, which can ensure that the second cover plate 130 is more stable in the flattened state and when switching from the flattened state to the flipped state.

[0126] In one possible implementation, see [reference] Figure 11 , Figure 13 and Figure 15 As shown, the flipping structure 160 includes a second support plate 164, which is connected to and protrudes outward from the front edge 121 of the first cover plate 120. The second support plate 164 extends in the X direction and protrudes beyond the front edge 121 of the first cover plate 120. The second support plate 164 is used to contact a portion of the inner surface of the second cover plate 130 in the flattened state, and to support the rear end edge 133 of the second cover plate 130 in the flipped state.

[0127] In this embodiment of the application, the inner surface 134 of the second cover plate 130 is the surface of the second cover plate 130 on the Z-reverse side.

[0128] When the first cover plate 120 and the second cover plate 130 are in a flattened state, refer to Figure 13As shown, the second cover plate 130 is connected to the first cover plate 120. The second cover plate 130 overlaps the second support plate 164. The surface of the second support plate 164 facing away from the bottom wall 115 contacts a portion of the inner surface 134 of the second cover plate 130 to support the second cover plate 130, improve the fit between the second cover plate 130 and the second support plate 164, and ensure that the first cover plate 120 and the second cover plate 130 maintain good rigidity in the flattened state.

[0129] When the first cover plate 120 and the second cover plate 130 are in the flipped state, refer to Figure 15 As shown, the front end of the second cover plate 130 is separated from the base 110, and the rear end of the second cover plate 130 is connected to the first cover plate 120 and inclined relative to the first cover plate 120. After the second cover plate 130 is flipped, the surface of the second support plate 164 facing away from the bottom wall 115 is used to support the rear end edge 133 of the second cover plate 130. The second support plate 164 provides stable support for the flipped second cover plate 130, ensuring the stability of the second cover plate 130 in the flipped state.

[0130] The area of ​​the second support plate 164 is larger than that of the first support plate 163, and it is located at the middle position of the first cover plate 120 extending along a second direction, which is the direction in which the two sidewalls of the base are arranged opposite each other. In this embodiment, the second direction is the Y direction, and the second support plate 164 is located at the middle position of the front edge 121 of the first cover plate 120 in the Y direction. The larger area allows the second support plate 164 to better support the second cover plate 130 in both the flattened and flipped states, improving the stability between the second cover plate 130 and the first cover plate 120. The second support plate 164 being located at the middle position of the front edge 121 of the first cover plate 120 in the Y direction makes the force on the second cover plate 130 more balanced when it contacts the second support plate 164 in both the flattened and flipped states, reducing the risk of swaying or tilting caused by asymmetrical force. The first support plate 163 and the second support plate 164 jointly support the second cover plate 130, improving the stability between the second cover plate 130 and the first cover plate 120.

[0131] In one possible implementation, see [reference] Figure 11 and Figure 13 As shown, the second cover plate 130 also includes a slot 136, which is disposed on the inner surface 134 of the second cover plate 130 and faces the second support plate 164 along the Z direction. In the flattened state, the second support plate 164 is located within the slot 136 and contacts the inner wall surface of the slot 136 to achieve connection and limit between the first cover plate 120 and the second cover plate 130, preventing relative movement between the second cover plate 130 and the first cover plate 120.

[0132] In one possible implementation, see [reference] Figure 11 and Figure 13As shown, there are two first support plates 163, located at opposite ends of the first cover plate 120 in the Y direction, and a second support plate 164 located between the two first support plates 163. The two first support plates 163 are symmetrically arranged on both sides of the second support plate 164 in the Y direction. The first support plates 163 and the second support plate 164 jointly support the second cover plate 130 in both the flattened and flipped states, making the force on the second cover plate 130 more even.

[0133] The number of first portions 161 is at least two and an even number. The number of first portions 161 can be two, four, six, etc. In this embodiment, the number of first portions is four. Half of the first portions 161 are located between one of the first support plates 163 and the second support plate 164, and the other half are located between the other first support plate 163 and the second support plate 164. The first portions 161 also support the second cover plate 130 in both the flattened and flipped states. The fact that the first portions 161 are symmetrically arranged on both sides of the second support plate 164 in the Y direction ensures that the second cover plate 130 is more stable and symmetrical in the flattened state and when switching from the flattened state to the flipped state.

[0134] In one possible implementation, see [reference] Figure 7 As shown, the first cover plate 120 includes two opposing protruding limiting portions 122, which are located at both ends of the front edge 121 of the first cover plate 120. The two protruding limiting portions 122 are arranged opposite each other along the Y direction at both ends of the front edge 121 of the first cover plate 120. The two protruding limiting portions 122 and the front edge 121 of the first cover plate 120 form an enclosing space 123. The second cover plate 130 has two opposing notches 137, which are located at both ends of the rear edge 133 of the second cover plate 130. The two notches 137 are arranged opposite each other along the Y direction at both ends of the rear edge 133 of the second cover plate 130. In the flattened state, the first cover plate 120 and the second cover plate 130 are connected, and the two protruding limiting portions 122 cooperate with the two notches 137 to achieve the limiting between the first cover plate 120 and the second cover plate 130. In this embodiment of the application, after the two protruding limiting parts 122 cooperate with the two notches 137 respectively, the protruding limiting parts 122 are located between the notches 137 and the side wall 117 of the base 110. The two protruding limiting parts 122 limit the second cover plate 130 in the Y direction to prevent the second cover plate 130 from moving relative to the first cover plate 120 in the Y direction.

[0135] In the flattened state, a portion of the second cover plate 130 extends into the enclosing space 123, and both the flipping structure 160 and the base connecting structure 135 are located within the enclosing space 123. Placing the flipping structure 160 and the base connecting structure 135 within the enclosing space 123 improves space utilization and makes the installation and maintenance of the second cover plate 130 and the first cover plate 120 more convenient and faster.

[0136] Multiple flipping structures 160 are placed within the enclosing space 123. The design of the flipping structures 160 is more concentrated, and the flipping structures 160 are arranged along the Y direction, making the flipping structures 160 approximately a flipping axis along the Y direction. The flipping axis serves as the rotation axis for the flipping of the second cover plate 130. When the second cover plate 130 switches between the flattened state and the flipped state, it can rotate smoothly around this axis, making the flipping of the second cover plate 130 smoother and more stable.

[0137] In one possible implementation, see [reference] Figure 2 and Figure 7 As shown, the first cover plate 120 also includes a limiting protrusion 124, which is located on the surface of the protruding limiting portion 122 facing the side wall 117 and extends toward the bottom wall 115. The limiting protrusion 124 contacts the side wall of the base 110 to limit the first cover plate 120 and prevent the first cover plate 120 from moving relative to the base in the Y direction.

[0138] In one possible implementation, see [reference] Figure 1 As shown, the second cover plate 130 includes a pair of opposing protruding ears 138, which are located at opposite ends of the front end of the second cover plate 130. The third direction is the direction in which they are oppositely arranged between a pair of sidewalls of the base. The pair of protruding ears 138 extend outward relative to the side of the second cover plate 130 and are used to contact a pair of handle structures 118 of the base 110 to achieve connection and positioning between the second cover plate 130 and the base 110. The pair of handle structures 118 of the base 110 are arranged oppositely at opposite ends of the front end 113 of the base 110 along the Y direction.

[0139] In the flattened state, the protruding ear 138 protrudes from the front end 113 in the X direction. The surface of the protruding ear 138 facing the rear end 114 and the surface of the handle structure 118 facing away from the rear end 114 are in contact. The contact between the protruding ear 138 and the handle structure 118 achieves a limiting effect between the second cover plate 130 and the base 110, preventing the second cover plate 130 from moving relative to the base 110 in the X direction.

[0140] A pair of protruding ears 138 are used to receive external force to move the second cover 130 away from the base. When the fiber fusion tray 100 requires maintenance, the second cover 130 switches between a flattened state and a flipped state, with the front end of the second cover 130 moving away from the front end 113 of the base 110. At this time, the maintenance personnel can contact the protruding portion of the protruding ears 138 and apply external force to the protruding ears using this point as a force point, thereby switching the second cover 130 between the flattened and flipped states.

[0141] In one possible implementation, see [reference] Figure 2 and Figure 3 As shown, the base 110 includes protrusions 119, which are disposed on the side wall 117 of the base 110. There are at least two protrusions 119, and the number of protrusions 119 can be two, three, four, or more. At least two protrusions 119 are respectively located on the surfaces of the first cover plate 120 along its thickness direction on both sides. A groove 125 is provided on at least one surface of the first cover plate 120 along its thickness direction. The groove 125 can be located on the surface of the first cover plate 120 facing the bottom wall 115 of the base 110; the groove 125 can also be located on the surface of the first cover plate 120 away from the bottom wall 115; and the groove 125 can also be located on the surfaces of both sides of the first cover plate 120 along its thickness direction. The first cover plate 120 is sandwiched between at least two protrusions 119, and at least a portion of the protrusions 119 are located within the groove 125 to connect the first cover plate 120 and the base 110.

[0142] In one embodiment, see [reference] Figure 2 and Figure 3 As shown, the side wall of the rear end 114 includes four protrusions 119, two of which are located on the surface of the first cover plate 120 facing away from the bottom wall 115, and the other two are located on the surface of the first cover plate 120 facing the bottom wall 115. A groove 125 is located on the surface of the first cover plate 120 facing away from the bottom wall 115. When the first cover plate 120 is installed with the base 110, the first cover plate 120 is sandwiched between the protrusions 119 located on both sides of the first cover plate 120 in the thickness direction, and the two surfaces of the first cover plate 120 in the thickness direction contact the surfaces of the protrusions 119. The protrusions 119 on the side of the first cover plate 120 facing the bottom wall 115 support the first cover plate 120, and the protrusions 119 on both sides of the first cover plate 120 in the thickness direction limit the first cover plate 120 in the Z direction. Two protrusions 119 located on the side of the first cover plate 120 away from the bottom wall 115 are located in the groove 125. The protrusions 119 are accommodated in the groove 125 to reduce the thickness of the first cover plate 120.

[0143] This application also provides an optical fiber distribution device 10, see reference. Figure 5As shown, the fiber optic distribution device 10 includes multiple optical fibers 200 and the fusion splice tray 100 described in any of the above embodiments. The multiple optical fibers 200 are located within the receiving space 111. When the first cover plate 120 and the second cover plate 130 are in a flattened state, they shield the receiving space 111, preventing water, dust, and other contaminants from entering and protecting the optical fibers 200 within the receiving space 111. The fiber optic ports 210 of the optical fibers 200 are fixed to the port fixing structures 140. Each optical fiber 200's fiber optic port 210 is fixed within each port fixing structure 140, with each optical fiber 200 corresponding to a single fiber optic port 210. When the second cover plate 130 switches from a flattened state to a flipped state, it exposes the fiber optic ports 210 and the front ends of the optical fibers 200.

[0144] The fiber optic distribution device 10 provided in this application includes a fusion splice tray 100. The second cover 130 of the fusion splice tray 100 can be opened when a patch cord port 310 is plugged into the fiber optic port 210, opening outwards towards the front end 113 to expose the fiber optic port 210. Since the second cover 130 only partially obscures the opening 112, during maintenance, it is only necessary to pull the fusion splice tray 100 from the frame 400 until the second cover 130 is fully opened to expose the fiber optic port 210, without needing to completely remove the base 110, thus improving maintenance convenience. Because the second cover 130 can be opened outwards towards the front end 113, when maintenance personnel perform maintenance on the fiber optic port 210, it is not necessary to disconnect all patch cord ports 310 and the fiber optic port 210; only the patch cord port 310 requiring maintenance needs to be precisely disconnected from the fiber optic port 210 for repair, improving both the convenience and accuracy of maintenance.

[0145] This application also provides a meltblown fabrication tray 100 with an electronic tag, including an electronic tag and the meltblown fabrication tray 100 described in any of the above embodiments, see reference. Figure 1 As shown, electronic tags are set on the second cover plate 130 and correspond one-to-one with the fiber optic ports 210 to record information of the fiber optic ports 210. It can be understood that "electronic tags on the second cover plate 130" here refers to the first electronic tag 150 being located on the second cover plate 130. Both the first electronic tag 150 and the second electronic tag 520 are electronic tags; when the electronic tag is fixed to the second cover plate 130, it is the first electronic tag 150, and when the electronic tag is fixed to the connecting rope 500, it is the second electronic tag 520. The terms "first," "second," etc., are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order.

[0146] This application also provides an optical communication device 20, see reference. Figure 3 and Figure 4As shown, the optical communication device 20 includes a first electronic tag 150, a second electronic tag 520, a jumper 300, and a fiber fusion splice tray 100 of any of the above embodiments. The first electronic tag 150 is disposed on the second cover plate 130 and is disposed in a one-to-one correspondence with the optical fiber port 210. The first electronic tag 150 has information about the optical fiber port 210.

[0147] The jumper 300 includes a jumper port 310 and a connecting rope 500. The jumper port 310 is plugged into the fiber optic port 210, enabling optical signal communication and transmission. One end of the connecting rope 500 is sleeved on the jumper 300, and the other end of the connecting rope 500 has a second electronic tag fixing structure 510 for fixing a second electronic tag 520. Each jumper 300 is sleeved with a connecting rope 500, and each second electronic tag 520 is connected to each jumper 300 through the connecting rope 500. Each second electronic tag 520 records information corresponding to each jumper 300. After the jumper 300 is plugged into the optical fiber 200, the second electronic tag fixing structure 510 on the connecting rope 500 is connected to the first electronic tag fixing structure 131 on the fusion splice tray 100. The second electronic tag 520 fixed on the second electronic tag fixing structure 510 is electrically connected to the first electronic tag 150 fixed on the first electronic tag fixing structure 131. The connecting rope 500 is flexible. When the second cover plate 130 is opened to expose the optical fiber port 210 in the direction of the front end 113, the connecting rope 500 bends. Maintenance personnel can open the second cover plate 130 for maintenance while the jumper port 310 is plugged into the optical fiber port 210, without having to disconnect all jumper ports 310 and optical fiber ports 210.

[0148] In one embodiment, the second electronic tag 520 and the first electronic tag 150 are coplanar. The first electronic tag 150 is located on the surface 132 of the second cover plate 130 away from the bottom wall 115. This surface has a large area. The coplanarity of the second electronic tag 520 and the first electronic tag 150 makes reasonable use of the space of the surface 132 of the second cover plate 130 away from the bottom wall 115, which can reduce the space of the fiber melting tray 100 in the height direction.

[0149] In one embodiment, the connecting rope 500 is a retractable connecting rope. With the jumper port 310 connected to the fiber optic port 210 and the second electronic tag fixing structure 510 connected to the first electronic tag fixing structure 131, when the front end of the second cover plate 130 is flipped towards the rear end 114 of the base 110, the front end of the second cover plate 130 can stretch the connecting rope 500. The connecting rope 500 extends to accommodate different angles of flipping of the second cover plate 130, preventing the connecting rope 500 from breaking due to the flipping of the second cover plate 130. When the jumper port 310 is not disconnected from the fiber optic port 210 and the second electronic tag fixing structure 510 is not disconnected from the first electronic tag fixing structure 131, the second cover plate 130 can be opened to expose the fiber optic port 210, facilitating maintenance of the fiber optic port 210.

[0150] In one possible implementation, see [reference] Figure 16 and Figure 17 As shown, the optical communication device 20 includes a frame 400 for holding multiple fiber optic splice trays 100, which are stacked along a third direction. Each splice tray 100 is slidably connected to the frame 400 in a first direction, where the rear and front ends are positioned relative to each other. In this application, the first direction is the X-direction. Each splice tray 100 can slide relative to the frame 400 along the X-direction. When maintenance is required on the splice tray 100 or its internal structure, the splice tray 100 can be removed from the frame 400 along the X-direction for maintenance.

[0151] The travel of the melting tray 100 relative to the frame 400 and the size of the second cover plate 130 in the first direction (X direction) are related so that when the melting tray 100 slides out relative to the frame 400, the second cover plate 130 can leave the base 110.

[0152] In one embodiment, the travel distance of the fiber fusion tray 100 relative to the frame 400 is the length of the second cover plate 130 in the X direction. That is, the travel distance that the fiber fusion tray 100 can slide relative to the frame 400 in the X direction is the length of the second cover plate 130 in the X direction. When the fiber fusion tray 100 slides out relative to the frame 400, the second cover plate 130 completely leaves the frame 400, so that when the second cover plate 130 flips away from the base 110, it is not affected by the frame 400.

[0153] 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
