Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0048] As data center switch port speeds continue to increase, heat dissipation issues associated with high-power optical modules have become a system bottleneck. Co-packaging (CPO) is an important solution. Optical-to-electronic co-packaging (CPO) is a novel packaging technology that combines the chip and optoelectronic components into a single package. This solution offers advantages such as reduced packaging costs, improved packaging efficiency, and enhanced system performance. However, since the light source is located near the system chip, the system architecture requires optical fiber to reliably transmit the optical signal to the input / output (I / O) panel. This process requires efficient assembly and management of optical fibers.

[0049] As shown in Figures 1 and 2, an embodiment of the present application provides an optical fiber cable management device for an optoelectronic co-packaged switching chip, comprising: a tray 1 including a first surface; a fiber accommodating box 3 provided on the first surface of the tray 1; and a cable management frame 4 provided on the first surface of the tray 1 and comprising: a cable management portion 45 having a first optical fiber outlet 44; and a first fiber accommodating space A having a second optical fiber outlet 46, wherein the first optical fiber outlet 44 is used to allow the optical fiber in the cable management portion 45 to extend into the first fiber accommodating space A, the second optical fiber outlet 46 is used to allow the optical fiber in the first fiber accommodating space A to extend into the fiber accommodating box 3, and the first fiber accommodating space A is used to accommodate a first redundant portion of the optical fiber. The first fiber accommodating space A is located between the cable management portion 45 and the fiber accommodating box 3.

[0050] Optionally, the fiber accommodating box 3 includes a second fiber accommodating space B, and the second fiber accommodating space B is used to accommodate a second redundant portion of the optical fiber.

[0051] In one embodiment, an optical fiber cable management device for an optoelectronic co-packaged switching chip may include: a tray 1, a panel 2, a fiber optic box 3, and a cable management frame 4; the panel 2 is mounted on the end of the tray 1; the tray 1 may include a first surface, and the fiber optic box 3 and the cable management frame 4 are both fixedly mounted on the first surface. The cable management frame 4 may include a cable management portion 45 and a first fiber accommodating space A. The cable management frame 4 may also include a hollow area 43 for exposing the chip assembly 5 fixedly mounted on the tray 1; along the routing direction of the optical fiber 511, the optical fiber inlet of the cable management frame 4 faces the hollow area 43, the optical fiber inlet of the fiber optic box 3 is opposite to the optical fiber outlet of the cable management frame 4, and the optical fiber outlet of the fiber optic box 3 is opposite to the optical fiber interface on the panel 2; the fiber optic box 3 and / or the cable management frame 4 have a fiber accommodating space.

[0052] The above-mentioned optical fiber cable management device is used to manage the optical fibers 511 of the optoelectronic co-packaged switching chip. The chip assembly 5 containing the optoelectronic co-packaged switching chip is installed on the first surface of the tray 1 and is located in the hollow area 43 of the cable management frame 4. The cable management frame 4 and the fiber accommodating box 3 are both fixed to the first surface of the tray 1, and the panel 2 is fixed to the end of the tray 1. The optical fibers 511 connected to the chip assembly 5 pass through the cable management frame 4 and the fiber accommodating box 3 to reach the panel 2 to transmit the optical signal to the panel 2. The cable management frame 4 surrounds the chip assembly 5 through the hollow area 43, making it easier for the optical fibers 511 to enter the cable management frame 4. At the same time, the optical devices 51 installed at different positions around the chip in the chip assembly 5 require different lengths of optical fibers 511 to connect to the panel 2. The cable management frame 4 and / or the fiber accommodating box 3 can provide more fiber accommodating space. For example, the cable management frame 4 can have a fiber accommodating space A, and the fiber accommodating box 3 can also have a fiber accommodating space B, which is conducive to maintaining the consistency of the length of the optical fibers 511.

[0053] It should be noted that the chip assembly 5 is mounted on the tray 1 through the mainboard 6. The chip assembly 5 includes an optoelectronic co-packaged chip and one or more optical devices 51. There can be multiple optical devices 51, and multiple optical devices 51 are arranged around the optoelectronic co-packaged chip. The chip assembly 5 is located in the hollow area 43 of the wire management frame 4. That is, the non-hollow area of ​​the wire management part 45 of the wire management frame 4 surrounds the optical device 51 and the optoelectronic co-packaged chip, making it convenient for the optical fiber 511 connected to the optical devices 51 at different positions to enter the non-hollow area of ​​the wire management part 45. As shown in Figure 1, optical devices 51 are arranged around the optoelectronic co-packaged chip, and the wire management frame 4 is provided with an optical fiber entrance 48 at the position corresponding to each optical device 51, making it convenient for the optical fiber 511 connected to each optical device 51 to enter the non-hollow area of ​​the wire management part 45.

[0054] As shown in FIG2 , a fiber storage space A (first fiber storage space) is provided on the side of the cable management portion 45 close to the fiber storage box 3. Optical fibers 511 of different lengths can store redundant portions (first redundant portions) in the fiber storage space A, thereby ensuring that the lengths of the optical fibers 511 outside the cable management frame 4 are consistent. It is understood that the first redundant portion can be all or part of the redundant portion of the optical fiber other than the length required for wiring.

[0055] In one embodiment, the fiber accommodating space A may have a rectangular cross-section when viewed from above.

[0056] Additionally or alternatively, a fiber storage space B (second fiber storage space) can be provided on the side of the fiber storage box 3 close to the cable management frame 4. If the lengths of the optical fibers 511 stored in the fiber storage box 3 are different, the redundant portion (second redundant portion) of the optical fibers 511 in the fiber storage box 3 can be accommodated in the fiber storage space B, that is, the fiber storage space B can absorb the excess optical fiber length so that the length of the optical fibers outside the fiber storage space B in the fiber storage box 3 is consistent. It can be understood that the second redundant portion can be all or part of the redundant portion of the optical fiber other than the length required for wiring.

[0057] In some embodiments, the height of the fiber accommodating space gradually increases in the direction in which the optical fiber in the accommodating space extends.

[0058] In some embodiments, an elastic shielding member (eg, conductive cotton 7 ) is provided between the fiber accommodating box 3 and the panel 2 .

[0059] In one possible implementation, as shown in Figures 1 and 2, the optical fiber outlet of the fiber optic box 3 can be the connection between the fiber optic box 3 and the panel 2. A connector 9 is provided on the panel 2, and the optical fiber 511 entering the fiber optic box 3 can be connected to the connector 9. Part of the connector 9 is located inside the fiber optic box 3, and part of it passes through the panel 2 and protrudes from the outer surface of the panel 2. The end of the connector 9 protruding from the panel 2 is sealed and dustproof by a dust plug 91. Among them, the connector 9 can be a single-fiber bidirectional Lucent Connector (LC). The outer surface of the panel 2 can be the surface of the side of the panel 2 facing away from the fiber optic box 3. In order to ensure the electromagnetic compatibility (EMC) shielding of the connector 9 in the system, the fiber optic box 3 is overlapped with the panel 2 through an elastic shielding member to prevent EMC leakage. The elastic shielding member not only plays a role in shielding and preventing leakage, but also can achieve the installation accuracy adjustment of the fiber optic box 3 and the panel 2 through its own elasticity.

[0060] In some embodiments, the elastic shielding member is conductive cotton 7. Conductive cotton 7 has excellent electrical conductivity and electromagnetic wave shielding properties. It is also highly elastic. Adding conductive cotton 7 between the fiber cassette 3 and the panel 2 not only compensates for installation tolerances between the fiber cassette 3 and the panel 2 but also provides effective shielding, preventing EMC leakage.

[0061] In some embodiments, the hollow area 43 is located in the middle of the cable management portion 45 of the cable management frame 4 ; the cable management frame 4 is provided with a plurality of optical fiber inlets, which are spaced apart around the hollow area 43 .

[0062] In one possible implementation, as shown in FIG2 , a hollowed-out area 43 is located at the center of the cable management portion 45, forming a substantially square structure. The cable management frame 4 is provided with four fiber optic inlets 48 corresponding to the optical devices 51 on the four sides of the chip assembly. These four fiber optic inlets 48 are spaced around the four sides of the square hollowed-out structure to facilitate entry of optical fibers 511 connected to optical devices 51 at different locations into the non-hollowed-out area of ​​the cable management portion 45. Optical fibers 511 connected to fiber optic inlets 48 on the cable management frame 4, which are relatively far from the fiber accommodating box 3, are first routed around the hollowed-out area 43 before entering the fiber accommodating space A on the cable management frame 4, allowing the fiber accommodating space A to accommodate the redundant portion of optical fibers 511.

[0063] In some embodiments, a fiber optic fixing assembly 8 is provided at the fiber optic entrance of the cable management rack 4 and / or the fiber optic entrance of the fiber optic box 3; the fiber optic fixing assembly 8 includes a fiber optic fixing seat 81 and a fiber optic fixing pressure block 82; the fiber optic fixing seat 81 is provided with a fiber optic fixing groove that passes through the fiber optic fixing seat 81; and the fiber optic fixing groove has an opening on the side away from the tray 1; the fiber optic fixing pressure block 82 is fixed to the fiber optic fixing seat 81 and covers the opening.

[0064] In one possible implementation, as shown in FIG1 , a fiber optic fixing assembly 8 is provided at the fiber optic inlet of the cable management frame 4 for fixing the optical fiber 511. The fiber optic inlet of the cable management frame 4 is close to the optical device 51, and the optical fiber 511 is connected to the optical device 51. Since the optical fiber 511 needs to travel a very long path to connect to the connector 9, in order to prevent the optical fiber 511 from shaking relative to the optical device 51 and causing the connection to fail, a fiber optic fixing assembly 8 is provided between the optical device 51 and the cable management frame 4, and the optical fiber 511 is placed in the fiber optic fixing groove of the fiber optic fixing seat 81. The fiber optic fixing pressure block 82 is placed above the optical fiber 511 and is connected and fixed to the fiber optic fixing seat 81 by connectors such as screws, for pressing and fixing the optical fiber 511. In order to protect the optical fiber 511, a protective cover is provided on the portion of the optical fiber 511 located in the fiber optic fixing groove.

[0065] In one possible implementation, as shown in FIG2 , a fiber fixing assembly 8 is provided at the fiber entrance of the fiber cassette 3 for fixing the optical fiber 511. The fiber entrance of the fiber cassette 3 is close to the fiber storage space A (first fiber storage space) of the cable management frame 4, and the fiber storage space A can accommodate a certain length of optical fiber 511. The volume of the fiber cassette 3 can be smaller than the volume of the cable management frame 4, and the optical fiber 511 in the fiber cassette 3 is connected to the connector 9. The fiber fixing assembly 8 can be provided between the fiber cassette 3 and the cable management frame 4 so that even if vibration or shaking occurs, the optical fiber 511 is not easily displaced relative to the connector 9, thereby causing the connection to fail. The optical fiber 511 is placed in the optical fiber fixing groove of the optical fiber fixing seat 81, and the optical fiber fixing pressure block 82 is placed above the optical fiber 511 and is connected to the optical fiber fixing seat 81 by screws or other connecting parts to press and fix the optical fiber 511. To protect the optical fiber 511, the portion of the optical fiber 511 located in the optical fiber fixing groove is covered with a protective cover.

[0066] It is worth noting that the optical fiber fixing assembly 8 not only plays the role of installing and fixing the optical fiber inlet, but also can prevent EMC leakage.

[0067] In some embodiments, an elastic member is provided between the optical fiber fixing seat 81 and the optical fiber fixing pressing block 82 .

[0068] In one possible implementation, an elastic member, such as foam 83 , is provided between the optical fiber fixing seat 81 and the optical fiber fixing block 82 to provide an assembly tolerance space for the assembly between the optical fiber fixing seat 81 and the optical fiber fixing block 82 while providing protection for the optical fiber 511 .

[0069] In some embodiments, the cable management rack 4 includes a body 41 and a protective cover 42 ; the protective cover 42 covers the side of the body 41 facing away from the tray 1 .

[0070] In one possible implementation, as shown in Figures 1 and 2, the cable management rack 4 can be a roughly closed chamber structure. In this way, the optical fiber 511 is not directly exposed to the environment, which can effectively protect the reliable splicing of the optical fiber 511 in the system air duct and prevent the optical fiber 511 from shaking under the suction of the fan of the entire system, thereby preventing poor splicing during optical signal transmission. The cable management rack 4 includes a main body 41 and a protective cover 42. The protective cover 42 can also include a first protective cover 421 and a second protective cover 422. Among them, the first protective cover 421 corresponds to the hollow area 43 on the cable management rack 4, and the second protective cover 422 corresponds to the fiber accommodating space A of the cable management rack 4. The fiber accommodating space A can absorb the excess length of the optical fiber 511 and achieve the purpose of unifying the optical fiber 511 for different connection distances. In Figure 1, the second protective cover 422 of the cable management rack 4 is also provided with a decorative cover, which makes the appearance of the cable management rack 4 more beautiful, and a brand mark can be set on the decorative cover.

[0071] It should be noted that the body 41 and the protective cover 42 are arranged vertically, that is, the opening of the body 41 faces upwards, which is convenient for cable management. The large opening facilitates the placement of the optical fiber 511 into a cable reel in the fiber storage space A. The upward direction is the direction from the tray 1 to the cable management frame 4.

[0072] In some embodiments, the body 41 defines a plurality of cable grooves 411 at the optical fiber outlet of the cable management frame 4 , such as the second optical fiber outlet of the fiber accommodating space A (ie, the first fiber accommodating space).

[0073] Since the fiber storage space A of the cable management frame 4 can store longer optical fibers 511, as shown in Figure 2, the excess optical fibers 511 are coiled into a ring and stored in the fiber storage space A. Since there are a large number of optical fibers 511, in order to better fix and distinguish each optical fiber 511, the main body 41 is provided with a plurality of cable grooves 411 at the optical fiber outlet of the cable management frame 4. Each cable groove 411 can only allow one optical fiber 511 or a group of optical fibers 511 to pass through, which is convenient for cable management and subsequent maintenance.

[0074] In some embodiments, the volume of the accommodation space A is greater than the volume of the accommodation space B.

[0075] In some embodiments, the fiber accommodating box 3 includes a box body 31 and a cover 32 ; the optical fiber inlet and the optical fiber outlet of the fiber accommodating box 3 are both provided in the box body 31 ; and the cover 32 covers the box body 31 .

[0076] In one possible implementation, as shown in FIG2 , the fiber cassette 3 is a generally closed chamber structure. This prevents the optical fiber 511 from being directly exposed to the environment, effectively protecting the reliable splicing of the optical fiber 511 within the system's air duct and preventing the optical fiber 511 from shaking under the suction of the system's fan, which could result in poor splicing during optical signal transmission. The fiber cassette 3 includes a box body 31 and a cover 32 . The cover 32 is located on the side of the box body 31 and is the largest side of the box body 3 , facilitating the connection between the optical fiber 511 and the connector 9 and facilitating subsequent maintenance.

[0077] In some embodiments, there are multiple fiber accommodating boxes 3 , and the multiple fiber accommodating boxes 3 are arranged along the extending direction of the panel 2 .

[0078] In one possible implementation, as shown in FIG1 and in conjunction with FIG2 , the optical fiber cable management device provided in this embodiment is provided with a plurality of fiber accommodating boxes 3, and the plurality of fiber accommodating boxes 3 are arranged along the length direction of the panel 2, and the plurality of fiber accommodating boxes 3 all correspond to the same cable management frame 4. For example, the length direction of the fiber accommodating space A of the cable management frame 4 is the same as the length direction of the panel 2, and the optical fiber inlets of the fiber accommodating boxes 3 all correspond to the fiber accommodating space A of the cable management frame 4 and are arranged along the length direction of the fiber accommodating space A.

[0079] The optical fiber management device provided in the embodiment of the present application is simple to produce and assemble, and is convenient to modulate and test; it can maintain consistent material length for different optical fiber connection distances; and it can also effectively protect optical fiber cables.

[0080] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present application without departing from the spirit and scope of the present application. Thus, if such modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is intended to include such modifications and variations.
