[0002] This application claims priority to the following patent application:

[0003] (1) Chinese patent application No. 202410739085.9, filed on June 7, 2024, entitled “Optical module facilitating cleaning of optical fiber interface and method of use thereof”. TECHNICAL FIELD

[0004] The present application relates to the field of optical communication technology, and in particular to an optical module facilitating cleaning of an optical fiber interface and a method of use thereof. BACKGROUND

[0005] The existing optical communication active optical module, as a core component of modern communication technology, has always been concerned about its design and manufacturing process. The optical communication active optical module on the market currently adopts a traditional independent part precision assembly combination method. In the prior art, as shown in FIGS. 1a and 1b, the fiber disc cover 1’ and the optical device 2’ are both independently arranged in the internal structure of the optical module package structure. For example, with an optical fiber bending radius of 6 mm, the optical fiber bending diameter is 12 mm. Adding the space installation gap of the fiber disc cover 1’, 15*15 mm2 of space is occupied. The optical device 2’ moves towards the optical fiber interface, resulting in a reduction in the layout space of the printed circuit board (PCB). A double-layer printed circuit board design must be used. However, the double-layer PCB 3’ requires a soft band for communication connection, which dramatically increases the manufacturing cost. In addition, the heat dissipation problem of the double-layer PCB 3’ is very difficult to solve. The optical module dissipates heat through the top of the module. A board is sandwiched between the top of the module and the PCB mainboard, making heat dissipation difficult. In addition, the disassembly of the double-layer PCB 3’ is also cumbersome. Therefore, the occupation of the space of the double-layer PCB 3’ will introduce many photoelectric problems.

[0006] In addition, if the optical device has a tail fiber, the optical fiber pin is easily rotated when the cleaning rod is used to clean the optical fiber interface, which causes the rear-end optical fiber to be twisted and broken. This is also a technical problem that needs to be solved in the cleaning process of the optical module.

[0007] Therefore, it is urgent to overcome the defects of the prior art in the technical field.

[0071] Embodiment 1:

[0072] The embodiment 1 of the present application provides an optical module convenient for cleaning optical fiber interface, as shown in FIG. 1 and FIG. 2, comprising: a packaging shell 1, a circuit board 2 and a fiber disc cover 3; the circuit board 2 and the fiber disc cover 3 are located inside the packaging shell 1, the circuit board 2 is provided with optical devices 25, and the fiber disc cover 3 covers the optical devices 25 area of the circuit board 2. Wherein, the circuit board 2 is a single-layer circuit board, the side of the circuit board 2 is provided with a positioning notch 21, and the bottom of the packaging shell 1 is provided with a positioning screw 22 to realize the positioning of the circuit board 2 in the packaging shell 1; referring to FIG. 4, the circuit board 2 is provided with optical devices 25, the optical devices 25 include but are not limited to a transmitting optical sub-assembley (TOSA) and a receiver optical subassembly (ROSA), wherein considering the size, layout and heat dissipation of the circuit board 2 and other factors, the TOSA 23 is not directly arranged on the circuit board 2, the TOSA 23 is designed and packaged as an independent module, so as to have better universality and maintainability, and meanwhile it is also beneficial to improve the overall performance and reliability of the optical module.

[0073] The packaging shell 1 comprises an upper cover 10 and a base 11, the upper cover 10 and the base 11 are fixedly connected, one end of the base 11 is provided with a fiber interface 110; specifically, the upper cover 10 and the base 11 can be fixedly connected by screws. As shown in Figure 4, the optical device 25 on the circuit board 2 is connected with the optical fiber pin 20, the optical fiber pin 20 comprises a front positioning column 200 and a rear positioning column 201, the front positioning column 200 and the rear positioning column 201 are rotationally connected, the front positioning column 200 is inserted into the fiber interface 110, and the rear positioning column 201 is clamped with the fiber cover 3; in an embodiment, the type of the optical fiber pin 20 can be Lucent connector (LC for short). As shown in Figures 5 and 6, the rear positioning column 201 is provided with a clamping disc 2010, one end of the fiber cover 3 is provided with a first clamping groove 30, the first clamping groove 30 is arranged on the side of the fiber cover 3 facing the fiber interface 110, when the rear positioning column 201 is clamped in the first clamping groove 30, the clamping disc 2010 abuts against the outer side wall of the fiber cover 3, and the clamping disc 2010 is limited by the fiber cover 3 and cannot rotate; wherein the fiber cover 3 is used for coiling optical fibers connected between all the optical devices 25 and the rear positioning column 201 and separating the optical devices 25. Specifically, a plurality of clamping claws 31 are arranged on the side of the fiber cover 3, and the clamping claws 31 are used for coiling the optical fibers connected between all the optical devices 25 and the rear positioning column 201. The upper surface of the fiber cover 3 comprises a skylight area and a closed area, the clamping claws 31 are respectively arranged above the frame of the skylight area and the upper surface of the closed area.

[0074] Among them, the number of optical fiber pins 20 is 2, one of the optical fiber pins 20 is connected with the TOSA 23, and the other optical fiber pin 20 is connected with the ROSA 24, and the front end of the front positioning column 200 of the optical fiber pin 20 is provided with an optical port, which is used for light out or light in.

[0075] Compared with the prior art of independently arranging the optical device 25 and the fiber cover 3, the embodiment of the application covers the fiber cover 3 above the optical device 25 area of the circuit board 2, realizes the coiling of the optical fiber on the fiber cover 3 without occupying the space in the packaging shell 1 for layout of the optical device 25 and the circuit board 2, thereby avoiding double-layer layout of the circuit board 2 in the optical module, improving the heat dissipation capacity of the optical module, and further improving the performance of the optical module.

[0076] In the second aspect, the present application sets the clamping disc 2010 on the rear positioning column 201 of the optical fiber plug 20, and cooperates the clamping disc 2010 with the disc fiber cover 3 to make the rear positioning column 201 of the optical fiber plug 20 unable to rotate, so that the optical fiber fixed on the rear positioning column 201 cannot be twisted, and the problem that the rear optical fiber is twisted and broken when the cleaning rod is used to clean the optical fiber interface 110 and drives the optical fiber plug 20 to rotate is solved.

[0077] According to the above-mentioned scheme, the structural details of the above-mentioned scheme will be further described in detail.

[0078] In the above-mentioned scheme, the clamping disc 2010 is in abutment with the outer side wall of the disc fiber cover 3, and the clamping disc 2010 is limited by the disc fiber cover 3 and cannot rotate. Specifically, in an embodiment, continuing to refer to FIGS. 5 and 6, the outer side bottom of the end face of the disc fiber cover 3 where the first clamping groove 30 is located is provided with an anti-rotation boss 33, and the bottom surface of the clamping disc 2010 is a horizontal plane. When the rear positioning column 201 is clamped in the first clamping groove 30, the bottom surface of the clamping disc 2010 is in abutment with the upper surface of the anti-rotation boss 33. The bottom of the clamping disc 2010 is provided as a plane, so that the plane is in abutment with the upper surface of the anti-rotation boss 33, which can ensure that the clamping disc 2010 does not rotate. In addition, the plane on the clamping disc 2010 does not necessarily have to be provided at the bottom, but can also be provided on the side or top. Correspondingly, the anti-rotation boss 33 is adjusted according to the position of the plane on the clamping disc 2010 to ensure that the plane on the clamping disc 2010 is in abutment with the plane of the anti-rotation boss 33.

[0079] In the above-mentioned structure, the front positioning column 200 is inserted into the optical fiber interface 110. Specifically, as shown in FIGS. 7 and 8, the inner end face of the base 11 is provided with a positioning hole 111, the positioning hole 111 is in communication with the optical fiber interface 110, the positioning hole 111 is located at the center position of the optical fiber interface 110, and the positioning hole 111 is used to accommodate the front positioning column 200. Therefore, when the optical fiber plug 20 is installed, it is inserted into the inside of the optical fiber interface 110 from the positioning hole 111.

[0080] As shown in FIG. 8 and FIG. 9, a double-hole wave-absorbing sheet 4 is arranged between the clamping disc 2010 and the base 11, and two circular holes 40 are arranged on the double-hole wave-absorbing sheet 4, which are used for the front positioning column 200 to pass through and be inserted into the positioning hole 111. The reason for arranging the double-hole wave-absorbing sheet 4 between the optical fiber interface 110 and the optical fiber pin 20 is that the double-hole wave-absorbing sheet 4 is a kind of material that can absorb the electromagnetic wave energy projected onto its surface, and plays a role of absorbing the electromagnetic radiation that may be generated in the optical module, which helps to reduce the potential impact of electromagnetic radiation on equipment and environment; secondly, the double-hole wave-absorbing sheet 4 can effectively absorb the leaked electromagnetic radiation that may be generated, so as to achieve the purpose of removing electromagnetic interference, and can ensure the normal work of the optical module and improve the stability and reliability of the system; in addition to the above direct effects, the double-hole wave-absorbing sheet 4 can also optimize some performance parameters of the optical module through its special structure and material properties, for example, through the design and application of the wave-absorbing material, the performance indicators such as insertion loss and return loss of the optical module can be improved.

[0081] Considering that the disc fiber cover 3 is arranged inside the packaging shell 1 and covers the optical device 25, even if the disc fiber cover 3 can be limited by the protruding optical device 25, during the process of taking out or installing the optical module, the optical module will inevitably be tilted due to operation, and relying only on the optical device 25 to limit or block the disc fiber cover 3 cannot completely guarantee the stability of the disc fiber cover 3 inside the packaging shell 1, therefore, as shown in FIG. 10 and FIG. 11, the inner side of the upper cover 10 is provided with a clamping plate 100, and two second clamping grooves 1000 are arranged on the clamping plate 100, the second clamping grooves 1000 are semicircular, and the second clamping grooves 1000 are clamped with the rear positioning column 201; when the second clamping grooves 1000 are clamped with the rear positioning column 201, the outer side surface of the clamping plate 100 abuts against the inner side surface of the disc fiber cover 3, so as to limit the disc fiber cover 3. Since the upper cover 10 and the base 11 are fixedly connected, the clamping plate 100 arranged on the upper cover 10 limiting the disc fiber cover 3 can guarantee that the disc fiber cover 3 remains stable in a shaking environment.

[0082] During the buckling process of the upper cover 10 and the base 11, high precision is required to make the screw holes on the upper cover 10 and the base 11 match for fixation, therefore, as shown in FIG. 12 and FIG. 13, positioning protrusions 101 are arranged on the two sides of the inside of the upper cover 10, and the outer profile of the positioning protrusions 101 matches the inner edge profile of the base 11 in the corresponding area; positioning bosses 112 are arranged on the two sides of the inside of the base 11, and the lower surface of the positioning protrusions 101 abuts against the upper surface of the positioning bosses 112 when the upper cover 10 and the base 11 are buckled. During the installation process, the coupling of the positioning protrusions 101 and the positioning bosses 112 can guarantee the coupling precision between the upper cover 10 and the base 11.

[0083] The optical devices 25 in the optical module, especially the light active devices, are responsible for converting electrical signals into optical signals or converting optical signals into electrical signals. If there is no proper isolation between the optical devices 25, the optical signals may interfere with each other, resulting in a decrease in signal quality and affecting communication performance. Therefore, as shown in FIGS. 14 and 15, the upper surface of the disc fiber cover 3 is provided with an isolation plate 32, the isolation plate 32 is provided with at least one clamping jaw 31, the isolation plate 32 and the side of the disc fiber cover 3 form a containing cavity for containing the optical devices 25 located on the circuit board 2, and the bottom surface of the isolation plate 32 is provided with a shielding partition plate 320 for isolating each of the optical devices 25. The area where the isolation plate 32 is located is the enclosed area of the disc fiber cover 3. Based on this, the isolation plate 32 can effectively prevent crosstalk between the optical signals of the optical devices 25, and the high-sensitivity optoelectronic devices can quickly and accurately detect and convert optical signals. However, if the distance between the optoelectronic devices is too close, they may be affected by the optical signals generated by each other, resulting in a decrease in sensitivity and signal stability. The use of the isolation plate 32 can ensure a proper distance between the optoelectronic devices, thereby improving signal stability.

[0084] In addition to the above structure, considering the heat dissipation requirement of the optical devices 25, as shown in FIGS. 16 and 17, the structure further includes a heat sink 5, the heat sink 5 includes a fitting surface 50 and a heat dissipation surface 51, the fitting surface 50 and the heat dissipation surface 51 are integrally formed; the fitting surface 50 is fitted with the bottom surface of the circuit board 2, and the heat dissipation surface 51 is fitted with the bottom surface of the optical device 25. Specifically, in this embodiment, the heat dissipation surface 51 is fitted with the bottom surface of the TOSA 23, and as shown in the dashed box in FIG. 18, the inner side of the base 11 is specially provided with a specific area for accommodating the heat sink 5.

[0085] In actual application scenarios, the chips provided on the circuit board 2 can include one or more of a microcontroller unit (MCU), a laser drive chip, a limiting amplifier, a clock and data recovery chip (CDR), a power management chip, and a digital signal processing (DSP) chip.

[0098] In one embodiment, the torsion spring 7 has one of a single annular shape, a double annular shape and a non-annular shape, and the torsion spring 7 has one of a single annular shape, a double annular shape and a non-annular shape, as shown in FIG. 24a-FIG. 24c, in addition to the single annular shape shown in FIG. 23, or the hook 70 of the torsion spring 7 is arranged towards the handle 62 of the pull ring 6.

[0099] Different from the scheme shown in Fig. 23a and Fig. 23b, in Fig. 24a, the torsion spring 7 comprises two annular portions, and corresponding to this, the first fixing plane 113 is provided with two fixing protrusions 1130, and each fixing protrusion 1130 is sleeved with an annular portion, so that the stability of the structure can be increased.

[0100] Different from the scheme shown in Fig. 23a and Fig. 23b, in Fig. 24b, the torsion spring 7 is a straight wire bent into a shape, the first fixing plane 113 is provided with a fixing protrusion 1130 and a limiting boss 63, the connecting part of the two horizontal arms of the torsion spring 7 is in a circular arc shape, the fixing protrusion 1130 and the limiting boss 63 clamp and fix the circular arc part of the torsion spring 7, and the two horizontal arms of the torsion spring 7 are in a preset angle shape with the opening facing the opposite direction of the handle 62 in the natural state. When the pull ring 6 is pulled, the clamping protrusion 611 drives the hook 70 to move in the pulling direction, and the opening angle of the two horizontal arms is increased.

[0101] Different from the scheme shown in Fig. 23b, in Fig. 24c, the first fixing plane 113 is provided with a fixing protrusion 1130, the torsion spring 7 comprises an annular portion, the hook 70 of the torsion spring 7 is arranged towards the handle 62 of the pull ring 2, and the end of the hook 70 is continuously extended and bent outwards to hook the clamping protrusion 611 towards the side of the handle 62.

[0103] According to the structure in the above scheme, in order to ensure the completeness of the scheme, the above structures will be further described in detail.

[0104] In the above scheme, the pull ring 6 includes fixed arms 60 respectively arranged on both sides, which abut against both sides of the packaging shell 1. Specifically, as shown in FIG. 25, both sides of the upper cover 10 are respectively arranged with first grooves 102 for accommodating the fixed arms 60, and both sides of the base 11 are respectively arranged with second grooves 115 for accommodating the fixed arms 60. When the upper cover 10 and the base 11 are buckled, the sum of the widths of the first grooves 102 and the second grooves 115 matches the width of the fixed arms 60. In an embodiment, as shown in FIGS. 26, 27 and 28, except for the protruding form of the top end of the fixed arms 60, the two fixed arms 60 present a trend of gradually approaching the distance between the handles 62 in the direction away from the handles 62, so the first grooves 102 and the second grooves 115 also present a form of gradually increasing depth on the upper cover 10 and the base 11.

[0105] When the optical module is put into the switch as a whole, the interface of the switch is provided with spring sheets 8 (see FIG. 29) for locking the optical module inserted into the switch in the switch. Based on this, as shown in FIGS. 25 and 29, the top edge of the first groove 102 is arranged with a first stop step 1020, and the edge of the second groove 115 is arranged with a second stop step 1150. The first stop step 1020 and the second stop step 1150 are located on the same horizontal line. When the optical module is inserted into the switch, the first stop step 1020 and the second stop step 1150 are used together to stop the spring sheet 8 of the switch.

[0106] After the optical module is inserted, maintenance or replacement of the optical module may be faced in the later use, at this time the spring 8 for fixing the optical module needs to be lifted to release the locking of the optical module by the switch, and the optical module is taken out from the switch. Based on this, as shown in FIG. 30, the top end of the fixing arm 60 is provided with an unlocking protrusion 600, when the fixing arm 60 is in a natural state in the first groove 102 and the second groove 115, the horizontal edges of the fixing arm 60 on both sides of the unlocking protrusion 600 abut against the first stop step 1020 and the second stop step 1150, and the height of the unlocking protrusion 600 is higher than the height of the first stop step 1020 and the second stop step 1150; wherein the unlocking protrusion 600 and the main body of the fixing arm 60 are smooth connection. Therefore, as shown in FIGS. 29 and 31, since the height of the unlocking protrusion 600 is higher than the height of the first stop step 1020 and the second stop step 1150, and the spring 8 abuts against the first stop step 1020 and the second stop step 1150, when the pull ring 6 is pulled, the pull ring 6 as a whole moves in the pulling direction, the unlocking protrusion 600 also moves backward, thereby lifting the spring 8. Since the unlocking protrusion 600 and the main body of the fixing arm 60 are smooth connection, that is, the unlocking protrusion 600 and the main body of the fixing arm 60 are arc connection, therefore the spring 8 will be lifted upward along the smooth surface between the unlocking protrusion 600 and the main body of the fixing arm 60, and separated from the optical module, to achieve unlocking.

[0107] Based on the structure of the unlocking protrusion 600, in the preferred scheme, by setting the unlocking protrusion 600 at the end of the fixing arm 60 of the pull ring 6, when the pull ring 6 is pulled out, the unlocking protrusion 600 can lift the spring 8 for fixing the optical module by the switch, so that the installation and disassembly between the optical module and the switch is more simple and convenient.

[0108] In order to make the fixed arm 60 better fit the first groove 102 and the second groove 115, prevent the fixed arm 60 from deforming after long-term use and not being able to completely fit the groove bottom of the first groove 102 and the second groove 115, as shown in FIGS. 30 and 32, the top plane of the first groove 102 is provided with a sunken groove 1021, which is arranged close to the first stop step 1020; the upper side of the fixed arm 60 is provided with a limiting protrusion 601, the width of the limiting protrusion 601 is less than the width of the sunken groove 1021; as shown in FIG. 33, when the fixed arm 60 is located in the first groove 102 and the second groove 115, the limiting protrusion 601 is located in the sunken groove 1021. Among them, considering the requirement that the arrangement of the sunken groove 1021 and the limiting protrusion 601 cannot block the movement of the pull ring 6 relative to the packaging shell 1, therefore in the scheme it is mentioned that the width of the limiting protrusion 601 is less than the width of the sunken groove 1021, that is, the distance that the fixed arm 60 can move relative to the packaging shell 1 is the width of the sunken groove 1021 minus the width of the limiting protrusion 601, and the width difference between the sunken groove 1021 and the limiting protrusion 601 should be able to ensure that the unlocking protrusion 600 can completely lift the spring sheet 8 of the switch, so that the spring sheet 8 does not contact the first stop step 1020 and the second stop step 1150.

[0109] In the foregoing scheme, it is mentioned that the cover plate 12 covers the second fixed plane 61, and the cover plate 12 is clamped and fixed with the base 11, wherein the specific way of clamping and fixing can be, as shown in FIGS. 34 and 35, the cover plate 12 is provided with a plurality of lock openings 120, the lock openings 120 are located on the side of the cover plate 12, the base 11 is provided with a plurality of lock heads 116, the lock heads 116 are located on the side of the base 11, the lock openings 120 and the lock heads 116 are correspondingly arranged, and when the lock heads 116 are located in the lock openings 120, the cover plate 12 is fixedly connected with the base 11. In an embodiment, the first fixed plane 113 of the base 11 is provided with a baffle 117 close to one side of the fiber interface 110, the outer side of the baffle 117 is provided with one lock head 116, the opposite side of the baffle 117 is provided with a boss 118, and the two sides of the boss 118 are respectively provided with one lock head 116; the cover plate 12 is processed to have three folded sides, the three folded sides are respectively located on the two sides of the cover plate 12 abutting against the boss 118 and the side abutting against the outer side of the baffle 117, and the lock openings 120 are arranged on the three folded sides of the cover plate 12; when the pull ring 6 is assembled with the base 11, the torsional spring 7 is sleeved on the fixed protrusion 1130, the bent hook 70 hooks the clamping protrusion 611, and after the lock openings 120 of the cover plate 12 are locked with the lock heads 116 on the baffle 117 and the boss 118, as shown in FIG. 36, the inner bottom surface of the cover plate 12 abuts against the lower end of the clamping protrusion 611.
