[0002] In the field of optical communication, extended beam optical connectors (EBO) have been gradually applied to high-density optical interconnect scenarios in data centers due to their advantages such as insensitivity to dust, stable insertion and removal losses, and low maintenance costs.

[0003] In existing optical modules, the adapter and fiber array are typically assembled in a coaxial horizontal or inclined configuration. The fiber array extends in a straight line, with the ferrule and adapter both set parallel to the bottom wall of the base. Horizontal arrangement significantly occupies the lateral space inside the optical module, resulting in a larger overall module size, making it difficult to meet the installation requirements of high-density integration. Summary of the Invention

[0004] The main objective of this invention is to propose an optical module that addresses the problems of messy fiber arrangement, poor ferrule-adapter connection accuracy, large space occupation, and low assembly reliability within the optical module.

[0005] To achieve the above objectives, the optical module proposed in this invention includes: Base; At least one adapter, each of the adapters being disposed on the base and perpendicular to the bottom wall of the base; The fiber array has a ferrule at one end, the ferrule and a portion of the fiber array extending into the adapter, the ferrule being perpendicular to the bottom wall of the base, and the end of the fiber array away from the ferrule being parallel to the bottom wall of the base.

[0006] In one embodiment, the fiber array includes a fiber receiver and a fiber transmitter. The end of the fiber receiver away from the ferrule is parallel to the bottom wall of the base. A portion of the structure of the fiber transmitter is located above the fiber receiver, and the end of the fiber transmitter away from the ferrule is parallel to the bottom wall of the base. Both the fiber receiver and the fiber transmitter are arranged linearly along a direction perpendicular to the bottom wall of the base.

[0007] In one embodiment, the optical module further includes two latches, each latch having a limiting space. The optical fiber receiving part has a plurality of first optical fibers, and the optical fiber transmitting part has a plurality of second optical fibers. A portion of the first optical fibers and a portion of the second optical fibers are confined within the limiting space of one latch; the remaining first optical fibers and the remaining second optical fibers are located within the limiting space of the other latch.

[0008] In one embodiment, the optical module further includes two adapters, a portion of the fiber array is connected to one of the adapters, and the remaining portion of the fiber array is connected to the other adapter; the base has a partition that divides the interior of the base into two chambers, each adapter is confined within one of the chambers, and each adapter is perpendicular to the bottom wall of the chamber.

[0009] In one embodiment, two limiting blocks are protruding from the two opposing inner walls of the chamber, and the two limiting blocks are disposed opposite to each other; an annular boss is protruding from the outer wall of the adapter along its circumference, and the annular boss abuts against the two limiting blocks.

[0010] In one embodiment, the inner wall of one side of the adapter has two insertion slots, which are spaced apart, and each insertion slot is configured as a plug connector.

[0011] In one embodiment, the adapter includes an outer cover and a base, the outer cover and the base forming a cavity; a guide block protrudes from the side of the outer cover facing the base; a buckle is sleeved on the outer side of the fiber array, the buckle engaging with the guide block.

[0012] In one embodiment, the base has a window on the side opposite to the outer cover, and the window is configured such that the external connector is exposed when it is plugged into the external connector.

[0013] In one embodiment, the buckle has a snap-fit ​​hole at one end facing the guide block, and the guide block snaps into the snap-fit ​​hole; the wall of the snap-fit ​​hole gradually expands from the end near the opening of the snap-fit ​​hole.

[0014] In one embodiment, the optical module further includes a circuit board disposed on the base, and the optical fiber array includes an optical fiber receiver and an optical fiber transmitter, both of which are electrically connected to the circuit board.

[0015] The optical module provided by this invention solves the problems of messy fiber arrangement, poor ferrule-to-adapter mating accuracy, large space occupation, and low assembly reliability by employing a base, an adapter perpendicular to the bottom wall of the base, and a fiber array with a specific arrangement. Specifically, the adapter is vertically mounted on the bottom wall of the base, and the ferrule of the fiber array is perpendicular to the bottom wall of the base, with part of the fiber extending into the adapter, achieving coaxial and precise alignment of the ferrule and adapter. Simultaneously, the end of the fiber furthest from the ferrule extends parallel to the bottom wall of the base, creating a regular spatial layout between the vertical mating and the horizontal fiber extension.

[0023] This invention proposes an optical module 100.

[0024] Please see Figure 1 , Figure 2In one embodiment of the present invention, the optical module 100 includes a base 1, at least one adapter 2, and an optical fiber array 3; each adapter 2 is disposed on the base 1 and perpendicular to the bottom wall of the base 1; one end of the optical fiber array 3 is provided with a ferrule 31, the ferrule 31 and part of the optical fiber array 3 extend into the adapter 2, the ferrule 31 is perpendicular to the bottom wall of the base 1, and the end of the optical fiber array 3 away from the ferrule 31 is parallel to the bottom wall of the base 1.

[0025] In this embodiment, the optical module 100 can be applied to scenarios such as high-speed interconnection in data centers, fiber optic access networks, and communication base stations, and is not limited here. The base 1 provides an installation reference and fixed support for all components, including the adapter 2 and fiber optic array 3. The base 1 can be made of metal or engineering plastic, and is formed in one piece. The adapter 2 enables precise docking between the fiber optic array 3 and external connectors, providing a channel for optical signal input / output; the external connector can be an optical patch cord connector, etc., and is not limited here. The number of adapters 2 can be one or two, and the connection between the adapter 2 and the base 1 can be fixed by a snap-fit ​​4, a threaded connection, or adhesive bonding. The fiber optic array 3 is the core carrier for optical signal transmission, and its function is to achieve centralized transmission of optical signals. It is composed of multiple optical fibers, which can be ordinary optical fibers or polarization-maintaining fibers. The ferrule 31 is used to fix the ends of the optical fibers, ensuring precise positioning of the optical fibers and the adapter 2. It should be noted that the end of the fiber array 3 furthest from the ferrule 31 is parallel to the bottom wall of the base 1, allowing the optical fibers to form a 90-degree turn within the module. This satisfies the external vertical docking requirements while ensuring the fiber ends are horizontally and closely parallel, greatly optimizing the internal space utilization of the optical module 100 and achieving miniaturization and compactness. In one embodiment, the ferrule 31 at one end of the fiber array 3 is a ceramic ferrule 31, bonded to the fiber array 3 with epoxy adhesive. The ferrule 31 and a section of optical fiber extend into the adapter 2 as a whole, with the outer wall of the ferrule 31 and the inner wall of the adapter 2 having a clearance fit for coaxial positioning. The axis of the ferrule 31 is also perpendicular to the bottom wall of the base 1. In another embodiment, the fiber array 3 is divided into two fiber bundles, each with a ferrule 31 at its end, extending into the corresponding adapter 2. Both ferrules 31 maintain a vertical orientation. The two optical fibers are smoothly bent below the adapter 2, with the ends furthest from the ferrule 31 horizontally parallel to the bottom wall of the base 1 and leading to the same side, arranged neatly for easy coupling with the optical chip or circuit board 5.

[0026] The optical module 100 provided by this invention, through the use of a base 1, an adapter 2 perpendicular to the bottom wall of the base 1, and a fiber array 3 with a specific arrangement, can solve the problems of messy fiber arrangement, poor docking accuracy between the ferrule 31 and the adapter 2, large space occupation, and low assembly reliability within the optical module 100. Specifically, the adapter 2 is vertically mounted on the bottom wall of the base 1, and the ferrule 31 of the fiber array 3 is perpendicular to the bottom wall of the base 1, with part of the fiber extending into the adapter 2, achieving coaxial and precise alignment of the ferrule 31 and the adapter 2. At the same time, the end of the fiber away from the ferrule 31 extends parallel to the bottom wall of the base 1, so that the vertical docking and horizontal fiber outflow form a regular spatial layout. This structure not only ensures the docking accuracy and optical signal transmission stability between the ferrule 31 and the adapter 2, avoiding signal loss due to assembly misalignment, but also allows the fiber to be arranged in an orderly manner within the module, reducing bending stress and spatial interference, improving overall assembly efficiency and structural compactness, while reducing the risk of fiber damage and improving the reliability of the optical module 100.

[0027] In one embodiment of the present invention, the fiber array 3 includes a fiber receiver 32 and a fiber transmitter 33. The end of the fiber receiver 32 away from the ferrule 31 is parallel to the bottom wall of the base 1. A portion of the structure of the fiber transmitter 33 is located above the fiber receiver 32. The end of the fiber transmitter 33 away from the ferrule 31 is parallel to the bottom wall of the base 1. Both the fiber receiver 32 and the fiber transmitter 33 are arranged linearly along a direction perpendicular to the bottom wall of the base 1.

[0028] In this embodiment, combined with Figure 2 and Figure 3 The fiber optic receiver 32 is responsible for receiving and transmitting external optical signals. As a dedicated receiving optical path, it is separated from the transmitter to reduce interference from strong light at the transmitter to weak light at the receiver, thus improving receiving sensitivity and signal-to-noise ratio. The fiber optic transmitter 33 is responsible for transmitting and outputting internal optical signals. As a dedicated transmission channel, it can centrally arrange multiple transmitting optical fibers, spatially isolating it from the receiving channel to ensure that the receiving and transmitting optical paths do not interfere with each other, improving the stability of multi-channel transmission. It should be noted that both the fiber optic receiver 32 and the fiber optic transmitter 33 are integrated from multiple optical fibers. The number of fibers can be four, eight, sixteen, etc., and is not limited here. The optical fibers in the fiber optic receiver 32 and the fiber optic transmitter 33 have the same specifications, but the fiber length in the fiber optic transmitter 33 is slightly shorter than that in the fiber optic receiver 32, with its end near the ferrule 31 overlapping the fiber optic receiver 32. The multiple optical fibers of the optical fiber transmitter 33 correspond one-to-one with the optical fibers of the optical fiber receiver 32, and are also arranged linearly in the vertical direction. They are also aligned with the optical fibers of the optical fiber receiver 32 in the horizontal direction to ensure one-to-one matching with the channels inside the adapter 2 and avoid misalignment.

[0029] In one embodiment of the present invention, the optical module 100 further includes two latches 4, each latch 4 having a limiting space 41, the optical fiber receiving part 32 having a plurality of first optical fibers, the optical fiber transmitting part 33 having a plurality of second optical fibers, some of the first optical fibers and some of the second optical fibers being confined within the limiting space 41 of one latch 4; the remaining first optical fibers and the remaining second optical fibers being confined within the limiting space 41 of the other latch 4.

[0030] In this embodiment, combined with Figure 2 and Figure 9 The clip 4 is used to fix the optical fibers of the optical fiber receiver 32 and the optical fiber transmitter 33, preventing positional deviations caused by vibration and displacement, and ensuring the connection accuracy between the optical fiber and the adapter 2 and circuit board 5. It is understood that the clip 4 can be made of engineering plastic and is rectangular or arc-shaped. The limiting space 41 is used to accommodate and limit the optical fiber, achieving precise positioning. The limiting space 41 is provided inside the clip 4, and its cross-section is semi-circular or circular, with a diameter slightly larger than the outer diameter of the optical fiber. The clip 4 can be fixed to the adapter 2 by clip 4 connection, adhesive bonding, or other methods. Grouping and limiting the optical fibers of the optical fiber receiver 32 and the optical fiber transmitter 33 avoids congestion and inaccurate positioning caused by all fibers being concentrated in one clip 4. It also enables group management, facilitating subsequent maintenance and repair, and further improving the regularity of the optical fiber arrangement. As can be understood, referring to the figure, the optical fiber receiving unit 32 has 16 first optical fibers, and the optical fiber transmitting unit 33 has 16 second optical fibers. Eight first optical fibers with receiving function and eight second optical fibers with transmitting function are grouped together and confined within the limiting space 41 of a latch 4, and extend into one of the adapters 2. The remaining eight first optical fibers with receiving function and the remaining eight second optical fibers with transmitting function are grouped together and confined within the limiting space 41 of another latch 4, and extend into another adapter 2.

[0031] In one embodiment of the present invention, the optical module 100 further includes two adapters 2, a portion of the structure of the fiber array 3 is connected to one of the adapters 2, and the remaining structure of the fiber array 3 is connected to the other adapter 2; the base 1 has a partition 11, which divides the inner cavity of the base 1 into two chambers 12, each adapter 2 is confined within one chamber 12, and each adapter 2 is perpendicular to the bottom wall of the chamber 12.

[0032] In this embodiment, combined with Figure 1 , Figure 2 as well as Figure 8The two adapters 2 are independently configured to avoid mutual interference and improve transmission stability. Part of the fiber optic array 3 is connected to one adapter 2, and the remaining part is connected to the other adapter 2: dividing the fiber optic array 3 into two parts, each docking with one of the two adapters 2, achieves split-path transmission of optical signals, adapting to multi-channel transmission requirements. The partition 11 isolates the two adapters 2 and the two parts of the fiber optic array 3 from each other, preventing mutual interference between the optical signals of the two channels; the chamber 12 provides independent installation space for each adapter 2, facilitating the positioning and fixing of the adapter 2, avoiding positional deviations between the two adapters 2, and improving docking accuracy. It is understood that the connection between the partition 11 and the chamber 12 can be integrally formed, detachable snap-fit, adhesive, etc., but here the integral forming method is preferred. The partition 11 is directly injection molded from the base 1 body and is integrally fixedly connected to the inner wall of the chamber 12 without assembly gaps.

[0033] In one embodiment of the present invention, two limiting blocks 13 are protruded from the two inner walls of the chamber 12 and are arranged opposite to each other; the outer wall of the adapter 2 protrudes circumferentially to form an annular boss 21, which abuts against the two limiting blocks 13.

[0034] In this embodiment, combined with Figure 6 and Figure 7 The limiting block 13 is used for radial positioning and clamping of the adapter 2, preventing the adapter 2 from swaying or tilting left and right within the chamber 12. It cooperates with the annular boss 21 to restrict the axial movement of the adapter 2, preventing vertical displacement during assembly or use. The annular boss 21 forms a continuous bearing surface circumferentially, abutting against the limiting block 13, bearing axial force and restricting the vertical movement of the adapter 2. In one embodiment, the limiting block 13 is integrally formed with the chamber 12, protruding directly from the inner wall of the base 1. The two limiting blocks 13 are symmetrically arranged, and the annular boss 21 is integrally formed with the adapter 2. After assembly, the end face of the boss abuts against the plane of the limiting block 13. In another embodiment, the limiting block 13 is pre-embedded by injection molding or fixed to the opposite inner wall of the chamber 12 by adhesive, forming an abutment and limiting relationship with the annular boss 21.

[0035] In one embodiment of the present invention, two plug slots 22 are provided on one side of the inner wall of the adapter 2. The two plug slots 22 are spaced apart, and each plug slot 22 is configured as a plug connector.

[0036] In this embodiment, combined with Figure 8The insertion slot 22 provides insertion guidance and positioning for external connectors, ensuring accurate insertion and precise alignment with the internal fiber optic ferrule 31; it also prevents reverse insertion, thus preventing fiber end face collisions, scratches, and damage caused by reverse insertion. It is understood that the insertion slot 22 is integrally formed with the inner wall of the adapter 2, and is symmetrically spaced vertically along a direction perpendicular to the bottom wall of the base 1. The cross-sectional shape of the insertion slot 22 can be circular, rectangular, etc., and is not limited here.

[0037] In one embodiment of the present invention, the adapter 2 includes an outer cover 23 and a base 24, which together form an installation cavity; a guide block 231 protrudes from the side of the outer cover 23 facing the base 24; a buckle 4 is sleeved on the outer side of the fiber array 3, and the buckle 4 engages with the guide block 231.

[0038] In this embodiment, combined with Figure 5 The outer cover 23 is used to cooperate with the base 24 to form a closed mounting cavity; the base 24 is used to provide a mounting and positioning foundation for the adapter 2 and is fixed in place with the mounting cavity of the base 1. The guide block 231 is used to guide the insertion of the buckle 4, so that the buckle 4 can slide smoothly into place during assembly; it forms a locking limit with the buckle 4, restricting the axial movement and circumferential rotation of the fiber array 3. The buckle 4 is used to fit on the outside of the fiber array 3, hold and fix the fiber array 3, and engage with the guide block 231 to realize a reliable connection between the fiber array 3 and the adapter 2. It can be understood that the connection relationship between the outer cover 23 and the base 24 can be a buckle 4 connection, plug-in fit, threaded connection, adhesive fixation, etc., which is not limited here. The connection relationship between the guide block 231 and the outer cover 23 can be integral molding, welding, adhesive bonding, etc., and it is preferred here that the guide block 231 and the outer cover 23 are integrally molded. Referring to the figure, the cross-sectional area of ​​the guide wedge 231 gradually increases from the end near the end of the outer cover 23 to the end away from the end of the outer cover 23. In one embodiment, the buckle 4 has a snap-fit ​​hole 42, and the guide wedge 231 is directly snapped into the hole to achieve snap-fit ​​and limiting. In another embodiment, the buckle 4 has a snap-fit ​​groove on its side, and the guide wedge 231 slides into the snap-fit ​​groove along the slope to form a snap-fit. In yet another embodiment, the guide wedge 231 and the buckle 4 adopt a slope transition fit, which automatically guides it into place and locks it in place during assembly.

[0039] In one embodiment of the present invention, a window 241 is provided on the side of the base 24 away from the outer cover 23. The window 241 is configured such that when it is plugged into an external connector, the external connector is exposed in the window 241.

[0040] In this embodiment, combined with Figure 5Window 241 provides an observation channel for direct inspection of the external connector's end face for dirt, scratches, or foreign objects, allowing for timely detection of contamination issues affecting light transmission. Window 241 also provides space for cleaning operations, enabling spraying and wiping of the external connector's end face without disassembling adapter 2. The shape of window 241 can be rectangular, square, or circular, but a rectangular shape is preferred here. Furthermore, the edges of window 241 can be rounded to avoid stress concentration and prevent scratching tools or the connector during cleaning. Window 241 is positioned directly opposite the center of the connector's end face, ensuring the line of sight is perpendicular to the end face.

[0041] In one embodiment of the present invention, the buckle 4 has a snap-fit ​​hole 42 at one end facing the guide inclined block 231, and the guide inclined block 231 is snap-fitted within the snap-fit ​​hole 42; the hole wall of the snap-fit ​​hole 42 gradually expands from the end near the opening of the snap-fit ​​hole 42.

[0042] In this embodiment, combined with Figure 4 and Figure 9 The snap-fit ​​hole 42 is used to cooperate with the guide wedge 231 to form a snap-fit ​​limit, restricting the axial movement and circumferential rotation of the fiber array 3 within the adapter 2; it also provides space for the guide wedge 231 to be accommodated and positioned. Referring to the figure, the snap-fit ​​hole 42 is rectangular in shape, compared to the elliptical or semi-circular snap-fit ​​holes 42 in the prior art, which are difficult to fasten and open during actual operation. In the above arrangement, the opening has a gradually expanding structure, which can guide the guide wedge 231, making it easier for the guide wedge 231 to enter the snap-fit ​​hole 42, reducing the difficulty of assembly alignment, and making assembly smoother; it can effectively avoid rigid impact, jamming, or scratch damage between the guide wedge 231 and the end of the snap fastener 4 during assembly, improving the assembly yield.

[0043] In one embodiment of the present invention, the optical module 100 further includes a circuit board 5, which is disposed on the base 1. The fiber array 3 includes a fiber receiver 32 and a fiber transmitter 33, both of which are electrically connected to the circuit board 5.

[0044] In this embodiment, combined with Figure 1 and Figure 2The circuit board 5 is used to process, drive, and amplify electrical signals, providing transmission drive signals to the fiber optic transmitter 33 and receiving and processing electrical signals transmitted back from the fiber optic receiver 32. The circuit board 5 can be mounted on the base 1 by welding, bonding, or other methods. The fiber optic receiver 32 transmits externally input optical signals to the photodetector on the circuit board 5, completing the optical-to-electrical conversion; the fiber optic transmitter 33 converts the electrical signals generated by the drive circuit on the circuit board 5 into optical signals and transmits them outward, completing the electrical-to-optical conversion; both are mechanically fixed and signal-connected with the circuit board 5, forming a complete transceiver signal link, thereby realizing the bidirectional communication function of the optical module 100.
