[0031] The present invention will now be described in detail with reference to the accompanying drawings.
[0032] like Figures 1 to 4 As shown, an optical module adaptable to dual LC jumpers according to this utility model includes a base 1, an optoelectronic component 2 disposed on the base 1, and a pin assembly 3 electrically connected to the optoelectronic component 2. The optoelectronic component 2 includes a PCB board 21, an optical element 22 disposed on the PCB board 21, and an optoelectronic chip 23 disposed on the optical element 22. Multiple optoelectronic chips 23 are disposed, and the multiple optoelectronic chips 23 are arranged at intervals along the length direction of the optical element 22. The PCB board 21 is electrically connected to the multiple optoelectronic chips 23.
[0033] Two optical elements 22 are provided, spaced apart and arranged in parallel. Preferably, the optoelectronic chip 23 includes four pairs of single-channel VCSEL or PD optical chips and four pairs of single-channel LD or LA electrical chips. The four single-channel VCSEL or PD optical chips and the four single-channel LD or LA electrical chips are cut and then fixed to one optical element 22 by a surface mount process. The other four single-channel VCSEL or PD optical chips and the four single-channel LD or LA electrical chips are cut and then fixed to another optical element 22 by a surface mount process. Finally, the four pairs of single-channel VCSELs are bonded together by a wire bonding process. Alternatively, a PD optical chip and four pairs of single-channel LD or LA electrical chips can be connected to the PCB board 21. A coupler is used to couple two optical elements 22 onto the PCB board 21, and then adhesive is used to firmly bond and fix the two optical elements 22 to the PCB board 21. This effectively mounts and fixes the PCB board 21, along with the two optical elements 22, onto the base 1, facilitating subsequent electrical connection between the two optical elements 22 and the pin assembly 3. This structural design makes the connection and disconnection between the optoelectronic component 2 and the pin assembly 3 more convenient and faster, with high adaptability, improving operational flexibility and reliability. This application is based on a 100G QSFPSWDM4 optical module using COB technology. This utility model can utilize existing dual LC optical fibers, upgrading to a 100G network, reducing fiber and engineering costs, simplifying operation procedures and complexity, and offering high adaptability.
[0034] In this embodiment, the optical element 22 is provided with a positioning post 24, and the PCB board 21 is provided with a positioning groove 25, in which the positioning post 24 is accommodated. Specifically, the positioning post 24 is vertically arranged on the top of the optical element 22, and the optical element 22 is inserted into the positioning groove 25 through the positioning post 24, thereby achieving accurate fixing of the optical element 22 on the PCB board 21 with good positioning effect.
[0035] The pin assembly 3 in this embodiment includes an LC ferrule 31, an optical fiber 32 connected to the LC ferrule 31, and an LC plug 33 connected to the optical fiber 32. A slot 26 is provided at one end of the optical element 22 near the LC ferrule 31, and the LC ferrule 31 is housed within the slot 26. An LC adapter 11 is provided in the base 1, and the LC plug 33 is housed within the LC adapter 11. Specifically, one end of the optical fiber 32 is connected to the LC ferrule 31, and the other end is connected to the LC plug 33, thereby connecting the optical element 22 to the LC ferrule 31 via the slot 26. The LC adapter 11, mounted in the base 1, is connected to the LC plug 33, thus achieving an electrical connection between the pin assembly 3 and the optical element 22. The connection is stable and reliable. When it is necessary to replace the optical element 22 with a different type, simply pull the LC ferrule 31 outward from the optical element 22 to remove the PCB board 21 along with the two optical elements 22 from the base 1.
[0036] In this embodiment, the base 1 is detachably provided with a cover 4. The cover 4 is provided with an upper receiving seat 41, which has an upper receiving groove 42. The base 1 is provided with a lower receiving seat 12, which has a lower receiving groove 13. The cover 4 and the base 1 are closed to each other so that the LC plug 33 is accommodated between the upper receiving groove 42 and the lower receiving groove 13. Specifically, when the cover 4 and the base 1 are closed, the LC plug 33 is accommodated between the upper receiving groove 42 and the lower receiving groove 13, so that the LC plug 33 is firmly installed between the cover 4 and the base 1, and a stable connection between the LC plug 33 and the LC adapter 11 is achieved on the base 1.
[0037] In this embodiment, one end of the base 1 is provided with a locking block 14, and one end of the cover 4 is provided with a locking groove 43 for accommodating the locking block 14. The other end of the base 1 is provided with a mounting base 15 and a mounting hole 16 provided in the mounting base 15. The other end of the cover 4 is provided with a through hole 44 and a connecting screw 45 provided in the through hole 44. The connecting screw 45 passes through the through hole 44 and is connected to the mounting hole 16. Specifically, the cover 4 is fixed by engaging with the locking block 14 through the locking groove 43, and the connecting screw 45 passes through the through hole 44 and is connected to the mounting hole 16, thereby realizing a detachable connection between the cover 4 and the base 1, which is convenient for installation and disassembly.
[0038] In this embodiment, a pull ring 5 is provided between the base 1 and the cover 4. The base 1 has placement channels 17 on both sides, and the cover 4 has locking grooves 46 on both sides. The pull ring 5 has extension arms 51 on both sides, extending away from the pull ring 5. Each extension arm 51 has a locking block 52 and is housed within the placement channels 17, allowing the locking block 52 to protrude into the locking grooves 46. Specifically, the pull ring 5 is housed within the placement channels 17 via the extension arms 51, and the extension arms 51 are accurately locked into the locking grooves 46 by the locking blocks 52, thus securely fixing the pull ring 5 between the base 1 and the cover 4. The pull ring 5 unlocks the connection between the optical module and the switch or network card spring clip; therefore, when removing the optical module, the pull ring 5 must be pulled to remove it smoothly.
[0039] In this embodiment, the base 1 is provided with an inner cavity 18, and a spring 19 is provided in the inner cavity 18. A protective cover 53 is provided between the pull ring 5 and the extension arm 51. The protective cover 53 is provided with a baffle 54, which abuts against the spring 19. Specifically, one end of the spring 19 abuts against the inner wall of the inner cavity 18, and the other end of the spring 19 abuts against the baffle 54. When an external pulling force is applied to the pull ring 5, the protective cover 53 covers the top of the inner cavity 18. The protective cover 53 compresses the spring 19 through the baffle 54, thereby allowing the optical module to be easily pulled out through the pull ring 5. When the external pulling force is no longer applied to the pull ring 5, the spring 19 will return to its original shape under the action of elasticity, releasing the stored energy, which is beneficial for the rapid reset of the pull ring 5.
[0040] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
