[0002] With the development of information technology, optical amplifiers are gaining increasing importance in optical communications and microwave photonics. Optical amplifiers are devices that amplify input light and are primarily categorized as fiber amplifiers and semiconductor optical amplifiers. Fiber amplifiers are a new type of amplifier capable of signal amplification. Because they do not require pattern shifting, fiber amplifiers are more suitable for use in optical fiber communication systems than semiconductor optical amplifiers.

[0003] When in use, connectors need to be installed at both ends of the optical fiber amplifier and connected to the optical fiber connector through the connectors.

[0004] To protect the connection between the connector and the optical fiber connector, conventional techniques generally provide a recess in the optical fiber amplifier and place the connector within the recess. However, when the optical fiber, connector, or optical fiber amplifier requires repair, the presence of the recess makes it very inconvenient to remove and assemble the optical fiber connector and connector during repair.

[0005] Based on this, the utility model provides an optical fiber amplifier which can protect the connection between the optical fiber connector and the connector and facilitates the assembly and disassembly of the optical fiber head. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Refer to the instruction manual Figure 1-Figure 5 The present invention provides a fiber optic amplifier that is easy to install and remove the optical fiber head, comprising a fiber optic amplifier body 10 and two connectors 20 for connecting optical fiber connectors. Both ends of the fiber optic amplifier body 10 are provided with mounting grooves 11 recessed into the interior of the fiber optic amplifier body 10, and the two connectors 20 are fixed in the two mounting grooves 11 respectively. Figure 1 and Figure 2 A first opening 12 is formed on the side of the optical fiber amplifier body 10 (facing outward from the page), through which the mounting slot 11 communicates with the exterior of that side of the optical fiber amplifier body 10. A baffle 13 is provided at the first opening 12 and is hingedly connected to the optical fiber amplifier body 10. The baffle 13 has at least a closed and an open state. When closed, it blocks the first opening 12, preventing the mounting slot 11 from communicating with the exterior through the first opening 12. When open, the baffle 13 exposes the mounting slot 11 from the side of the optical fiber amplifier body 10. This allows personnel to install or remove the connection between the optical fiber connector and the connector 20 through the first opening 12.

[0029] Furthermore, a detachably connected cover plate 14 is provided on the side of the optical fiber amplifier body 10 where the first opening 12 is located. Openings (not shown) are also formed at both ends of the cover plate 14 at positions corresponding to the first opening 12. A baffle 13 is hingedly connected to the openings in the cover plate 14.

[0030] A retaining wall 121 is provided in the first opening 12 , and a Velcro 131 is provided on the baffle 13 . The position of the Velcro 131 corresponds to the position of the retaining wall 121 . When the baffle 13 is in a closed state, the Velcro 131 is fixed to the retaining wall 121 to fix the baffle 13 in the first opening 12 .

[0031] A rectangular groove 132 is formed at one end of the baffle 13 away from the hinged connection with the cover plate 14 . The rectangular groove 132 is provided to facilitate staff in turning the baffle 13 .

[0032] Reinforcement components are provided at both ends of the fiber amplifier body 10 where the mounting slots 11 are provided. At each end of the fiber amplifier body 10 where the mounting slots 11 are provided, the reinforcement components include a card board 30. Each card board 30 includes at least two sub-boards 31. The two sub-boards 31 are located on the same plane. A notch 32 is formed at the end of the two sub-boards 31 that are close to each other. The two sub-boards 31 can be arranged perpendicular to the direction of insertion of the optical fiber (i.e., the direction of insertion of the optical fiber). Figure 4 The card plate 30 is movably arranged on the optical fiber amplifier body 10 so that the card plate 30 has two states (open and closed) Figure 4 Figure 3 shows the state of the card plate 30 when it is closed). When the card plate 30 is in the open state, the two sub-plates 31 are separated from each other to expose a space for the optical fiber connector to pass through. When the card plate 30 is in the closed state, the notches 32 of the two sub-plates 31 are spliced ​​together to form a channel for accommodating the optical fiber bundle.

[0033] Furthermore, a receiving groove 15 is formed at each end of the optical fiber amplifier body 10 where the mounting groove 11 is provided. The extending direction of the receiving groove 15 is perpendicular to the optical fiber insertion direction. The sub-board 31 is slidably disposed in the receiving groove 15 .

[0034] More specifically, a pressing plate 16 is fixed to each end of the optical fiber amplifier body 10 , and the receiving groove 15 is formed between the pressing plate 16 and the end surface of the optical fiber amplifier body 10 .

[0035] The pressing plate 16 is further provided with a sliding groove 161 that passes through the pressing plate 16 so that the receiving groove 15 is connected to the other side of the pressing plate 16, that is, the outside world, through the sliding groove 161. The sliding groove 161 extends along the moving direction of the sub-plate 31.

[0036] The reinforcement assembly also includes a spring latch 40, which includes a sleeve 41, an insert 42, a return spring 43 and a pull rod 44. The sleeve 41 is fixed along the insertion direction of the optical fiber and is arranged on the sub-board 31. The insert 42 can be movably arranged in the sleeve 41 along the axial direction of the sleeve 41, and the return spring 43 is connected between the sleeve 41 and the insert 42. The pull rod 44 passes through the slide groove 161 from the side of the pressure plate 16 away from the receiving groove 15, and is connected to the insert 42 after extending into the sleeve 41. When the return spring 43 is in a free state, the return spring 43 presses the insert 42 so that the insert 42 abuts against the bottom surface of the receiving groove 15 to fix the sub-board 31; when the pull rod 44 is pulled outward, the insert 42 retracts into the sleeve 41, and the return spring 43 is compressed to facilitate the movement of the sub-board 31.

[0037] Furthermore, a slot 151 is formed on the bottom surface of the receiving slot 15. When the insert block 42 abuts the bottom surface of the receiving slot 15, the insert block 42 extends into the slot 151. Each daughter board 31 has at least two corresponding slots 151. When the card 30 is in the closed state, the position of one slot 151 corresponds to the position of the insert block 42; when the card 30 is in the open state, the position of the other slot 151 corresponds to the position of the insert block 42. That is, when the card 30 is in the closed state, the corresponding insert block 42 on each daughter board 31 can extend into one slot 151; when the card 30 is in the open state (this open state can be a state that does not block the insertion of the optical fiber end), the corresponding insert block 42 on each daughter board 31 can extend into the other slot 151. This arrangement facilitates the positioning of the daughter boards 31 and ensures the stability of the positions of the daughter boards 31.

[0038] To connect the end of the optical fiber to the fiber amplifier body 10, the operator pulls the pull rod 44 to retract the insert 42 into the sleeve 41. This compresses the return spring 43 between the insert 42 and the sleeve 41. The operator then uses the pull rod 44 to pull the two sub-plates 31 apart along the slide groove 161, positioning the retaining plate 30 in the open position. Simultaneously, the baffle 13 opens, exposing the mounting slot 11 from the side of the fiber amplifier body 10. Once the end of the optical fiber is inserted into the mounting slot 11, it can be connected to the connector 20.

[0039] After the connection is complete, the pull rod 44 moves the daughter board 31, closing the clamping plate 30. The baffle 13 is then closed. At this point, the baffle 13 on the cover 14 and the clamping plate 30 together seal the mounting slot 11, preventing the optical fiber and connector 20 from colliding and affecting signal transmission.

[0040] When it is necessary to disassemble the optical fiber, the operator can open the clamping plate 30 and the baffle 13 again to disassemble the end of the optical fiber and the connector 20 .

[0041] Further, refer to the appendix of the manual Figure 2 and Figure 3 A transparent cover 17 is installed on top of the fiber amplifier body 10. One end of the cover 17 is hinged to the body 10, while the other end is free. When the cover 17 is attached to the body 10, the end of the cover 17 away from the hinge engages with the body 10. A control module 18 is installed on the top of the fiber amplifier body 10, on the side where the transparent cover 17 is installed. The cover 17 protects the control module 18 from collisions that could affect normal operation. To adjust the operation, operators simply flip open the cover 17.

[0042] like Figure 2 and Figure 3 As shown, a card slot 19 is provided at the bottom of the optical fiber amplifier body 10, that is, at the other side of the top of the optical fiber amplifier body 10 corresponding to the transparent cover 17. The card slot 19 facilitates the installation of the optical fiber amplifier body 10, thereby improving the firmness of the installation of the optical fiber amplifier body 10 and facilitating the installation and removal of light.

[0043] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
