Description

Technical Field

[0001] This utility model relates to the field of fiber optic transceiver technology, specifically a fiber optic transceiver chassis. Background Technology

[0002] With the widespread adoption of 5G, cloud computing, and the Internet of Things, network architecture is shifting from a centralized to a distributed + edge-based model, placing new demands on the deployment of fiber optic transceivers: the need for high-density networking in data centers; and the surge in the number of servers in data centers (from 10 servers per rack to 20-30 servers), requiring more fiber optic transceivers to achieve high-speed server-switch connections. Traditional 2U / 3U racks are relatively tall (≥88.9mm), and a standard 42U rack can only accommodate 14-21 servers, failing to meet the demand for "more ports per U," leading to limited rack space. Therefore, increasing density by "compacting rack height" has become an optimization direction, making the 1.5U specification a viable option. In response, this technical solution designs a fiber optic transceiver chassis that can accommodate a large number of fiber optic transceivers while also offering advantages such as convenient installation, disassembly, and replacement. Utility Model Content

[0003] The purpose of this invention is to provide a fiber optic transceiver chassis to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A fiber optic transceiver chassis includes a chassis and a base. The chassis is fixedly mounted on the base, and the bottom of the base is fixed to the ground of the place of use by means of anchor bolts or other structures. The front and rear sides of the chassis are open, and multiple sets of sliding rail mounting structures are arranged longitudinally at equal intervals inside. The fiber optic transceiver terminal box to be installed and used is moved inside and outside the chassis through the sliding rail mounting structures. The fiber optic transceiver terminal box includes a cable management rack and a fiber optic transceiver mounting rack. The fiber optic transceiver mounting rack is installed on the top of the cable management rack. Positioning components are provided on the front and back sides of the top of the fiber optic transceiver mounting rack. Multiple horizontally spaced fiber optic transceivers can be placed between the positioning components at the same time. The fiber optic transceivers are fixed by clamping them with the front and back sides of the positioning components. Then, combined with multiple vertically distributed fiber optic transceiver terminal boxes, the machine can accommodate a large number of fiber optic transceivers for installation and use at the same time. The top of the fiber optic transceiver mounting bracket has multiple positioning slots at equal intervals along the horizontal direction, and the bottom of the fiber optic transceiver is placed in the positioning slots for pre-positioning. The sliding rail mounting structure includes longitudinally spaced sliding rails on the inner side wall of the chassis. The front end of the sliding rail is open and the rear end is closed. Sliding strips are installed on both sides of the cable management rack. The sliding strips slide along the sliding rails to control the free sliding connection between the fiber optic transceiver terminal box and the chassis. A locking plate is installed on the side wall of the cable management rack located at the front end of the slide bar. A locking pin is installed on the side wall of the locking plate facing the front side wall of the chassis. A locking hole is opened on the front side wall of the chassis corresponding to the locking pin. After the slide bar slides to the maximum position inside the slide rail, the locking pin engages with the locking hole, thereby positioning the cable management rack together with the fiber optic transceiver mounting bracket and fiber optic transceiver on its upper side inside the chassis. The vertical cross-section of the slide rail and slide bar is set as a side-mounted "T" shaped structure to keep the slide bar stable and sliding inside the slide rail; The positioning assembly includes a front stop bar and a fixed backplate installed on the front and rear sides of the top of the fiber optic transceiver mounting bracket. The fixed backplate and the front stop bar are configured as a U-shaped structure, with their top height greater than the placement height of the fiber optic transceiver to be installed. Each positioning slot has a rotating fastener on the upper side of the corresponding front stop bar. By placing the fiber optic transceiver in the positioning slot, the rear side of the fiber optic transceiver contacts the fixed backplate, and the front side applies a backward pushing force to the fiber optic transceiver through the rotating fastener, thereby quickly fixing the fiber optic transceiver on the fiber optic transceiver mounting bracket.

[0005] Compared with the prior art, the beneficial effects of this utility model are: by adopting a compact 1.5U height design, the capacity of the 42U rack is increased by more than 40%, meeting the needs of high-density networking.

[0006] The sliding pull-out structure combined with locking pins enables quick insertion and removal of the terminal box; the screw-driven compression block enables tool-free assembly and disassembly of the fiber optic transceiver.

[0007] The positioning groove and fixed back plate prevent equipment displacement, and the extrusion block with buffer pad avoids component wear, ensuring reliable signal transmission. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please see Figures 1-5A fiber optic transceiver chassis includes a chassis 10 and a base 11. The chassis 10 is fixedly installed on the base 11. The bottom of the base 11 is fixed to the ground of the place of use by means of anchor bolts or other structures. The front and rear sides of the chassis 10 are open. Multiple sets of sliding rail mounting structures are arranged longitudinally at equal intervals inside the chassis. The fiber optic transceiver terminal box 12 to be installed and used is moved inside and outside the chassis 10 through the sliding rail mounting structures. The fiber optic transceiver terminal box 12 includes a cable management rack 15 and a fiber optic transceiver mounting rack 16. The fiber optic transceiver mounting rack 16 is installed on the upper side of the cable management rack 15. Positioning components are provided on the front and rear sides of the top of the fiber optic transceiver mounting rack 16. Multiple horizontally equally spaced fiber optic transceivers 17 can be placed between the positioning components at the same time. The fiber optic transceivers 17 are fixed by clamping them on the front and rear sides of the positioning components. Then, combined with multiple vertically distributed fiber optic transceiver terminal boxes 12, the machine can simultaneously accommodate a large number of fiber optic transceivers 17 for installation and use. The top of the fiber optic transceiver mounting bracket 16 is provided with multiple positioning slots 20 at equal intervals along the horizontal direction, and the bottom of the fiber optic transceiver 17 is placed in the positioning slots 20 for pre-positioning. The sliding rail mounting structure includes a slide rail 13 longitudinally and equally spaced on the inner side wall of the chassis 10. The front end of the slide rail 13 is open and the rear end is closed. At the same time, slide bars 25 are installed on both sides of the cable management rack 15. The slide bars 25 slide along the slide rail 13 to control the free sliding connection between the fiber optic transceiver terminal box 12 and the chassis 10. A locking plate 24 is installed on the side wall of the cable management rack 15 located at the front end of the slide bar 25. A locking pin is installed on the side wall of the locking plate 24 facing the front side wall of the chassis 10. A locking hole 14 is opened on the front side wall of the chassis 10 corresponding to the locking pin. After the slide bar 25 slides to the maximum position inside the slide rail 13, the locking pin engages with the locking hole 14, thereby positioning the cable management rack 15 together with the fiber optic transceiver mounting bracket 16 and the fiber optic transceiver 17 on its upper side inside the chassis 10. The vertical cross-section of the slide rail 13 and the slide bar 25 is set as a side-mounted "T" shaped structure to keep the slide bar 25 stable and sliding inside the slide rail 13. The positioning assembly includes a front stop bar 19 and a fixed back plate 18 installed on the front and rear sides of the top of the fiber optic transceiver mounting bracket 16. The fixed back plate 18 and the front stop bar 19 are configured as a U-shaped structure, and their top height is greater than the placement height of the fiber optic transceiver 17 to be installed. Each positioning slot 20 has a rotating fastener on the upper side of the corresponding front stop bar 19. By placing the fiber optic transceiver 17 in the positioning slot 20, the rear side of the fiber optic transceiver 17 contacts the fixed back plate 18, and the front side applies a backward pushing force to the fiber optic transceiver 17 through the rotating fastener, thereby quickly fixing the fiber optic transceiver 17 on the fiber optic transceiver mounting bracket 16. The fixed backplate 18 is installed on the upper side of the rear side of the positioning slot 20 to ensure that the rear side of the fiber optic transceiver 17 can contact the side wall of the fixed backplate 18, provided that the fiber optic transceiver 17 does not tilt.

[0019] The rotating fastener includes a screw 22 rotatably mounted on the front stop bar 19. The front end of the screw 22 is equipped with an internal hex nut 21, and the rear end is rotatably connected to a pressing block 23. Rotating the internal hex nut 21 controls the screw 22 to move back and forth, and then drives the pressing block 23 to contact the front side wall of the fiber optic transceiver 17 to press and fix it. Specifically, a buffer pad is provided on the side of the extrusion block 23 that contacts the fiber optic transceiver 17 to reduce the extrusion wear on the fiber optic transceiver 17.

[0020] In one embodiment of the present invention, the connection and operation process between the cable management rack 15, the fiber optic transceiver mounting bracket 16, and the fiber optic transceiver 17 are as follows: Optical signal access and distribution: The backbone optical cable from the operator or the upstream network equipment is introduced from outside the chassis 10 and enters the fiber optic transceiver terminal box 12. The optical cable is stripped and fixed inside the fiber optic transceiver terminal box 12. Each thin optical fiber in the optical cable is fused with a pigtail (optical fiber with a connector) on the splice tray. The other end of the pigtail is connected to the adapter panel (such as SC or LC interface) of the fiber optic transceiver terminal box 12. At this point, the external optical signal is distributed losslessly and "presented" on the adapter interface of the fiber optic transceiver terminal box 12, waiting for the device to connect.

[0021] Photoelectric conversion (fiber optic transceiver): Use a short fiber optic patch cord, insert one end into the interface on the adapter panel of the fiber optic transceiver terminal box 12, and the other end into the optical port (RX receiver) of the fiber optic transceiver 17. The optical signal enters the fiber optic transceiver 17 through a patch cord. The optical module inside the fiber optic transceiver 17 demodulates the optical signal and converts it into an electrical signal. The converted electrical signal is output through the electrical port (such as the RJ45 network cable interface) of the fiber optic transceiver 17.

[0022] At the same time, the electrical signal from the electrical port is converted into an optical signal and sent back to the network through the optical port (TX transmitter).

[0023] Meanwhile, during the fiber optic cable management and connection process, the cable management rack 15 is used to organize and store the fiber optic cables, forming a safe and aesthetically pleasing fiber optic distribution. Finally, a network cable is led out from the electrical port of the fiber optic transceiver and connected to the router, switch or other terminal equipment to provide network connectivity.

[0024] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components (representing power elements, electrical devices, and compatible power supplies) are connected via wires. The electrical connections are completed in sequence between the working components. The detailed connection methods are well-known in the field. The following mainly describes the working principle and process, without further explanation of the electrical control. The fiber optic transceiver terminal box 12 is pushed into the chassis 10 along the slide rail 13 via the slide bar 25 until the slide bar 25 reaches the closed position at the rear end of the slide rail 13. The latch of the latch plate 24 engages with the latch hole 14 on the front side of the chassis to lock the terminal box position; The bottom of the fiber optic transceiver 17 is inserted into the positioning slot 20 of the fiber optic transceiver mounting bracket 16, and its rear side is attached to the fixed back plate 18; rotate the internal hex nut 21 on the front stop bar 19 to drive the screw 22 to push the pressing block 23 to press the front side of the fiber optic transceiver 17.

[0025] Optical signal processing: The main optical cable is connected to the fiber optic transceiver terminal box 12, and after being fused with the pigtail via a fusion splice plate, it is connected to the adapter panel. Connect one end of the fiber optic patch cord to the adapter interface and insert the other end into the 17 optical port RX of the fiber optic transceiver. The fiber optic transceiver 17 converts optical signals into electrical signals and outputs them to the terminal device through the RJ45 network port. The reverse electrical signal is converted into an optical signal by the fiber optic transceiver 17 and transmitted back to the network via the optical port TX.

[0026] Maintenance procedures: Release the latch plate 24 from the latch hole 14 and pull the fiber optic transceiver terminal box 12 out of the chassis 10 along the slide rail 13. Rotate the internal hex nut 21 in the opposite direction to loosen the compression block 23, and directly replace the fiber optic transceiver 17.

[0027] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0028] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
