The embodiment is an optical module aging test bracket, and the specific structure thereof is shown in fig. 2 to 4.

As shown in fig. 2 and 3, the bracket includes a panel assembly 10, a tension column 30 and two side plates 20. The tension column 30 and the panel assembly 10 are connected by two side plates 20, and the side plates 20 are perpendicular to the central axis of the tension column 30, and the two side plates 20 are parallel to each other. The side plate 20 is fixedly connected to the panel assembly 10 at one end by screws and fixedly connected to the side of the tension column 30 at the other end by screws. The two side plates 20 are connected, and when the bracket is used, the side plates 20 can be held by an operator to pick up the whole bracket. The whole bracket is of a square structure. In one embodiment, the panel assembly 10, the side plate 20 and the tension column 30 may be made of aluminum alloy.

As shown in fig. 2 and 3, the panel assembly 10 includes a front panel 11 and a rear panel 12 secured to each other in a front-to-rear relationship. The front plate 11 and the rear plate 12 are fixed to each other by screws. The first largest surface 101 of one side of the panel assembly 10 is provided on the front plate 11, and the first largest surface 101 is provided with a first socket 111 of double rows. The second largest surface 102 on the other side of the panel assembly 10 is provided on the back plate 12, and a double row of second sockets 121 is formed on the second largest surface 102. The first sockets 111 and the second sockets 121 correspond one-to-one and communicate with each other. The first insertion opening 111 is used for the optical module to pass through, and the second insertion opening 121 is used for the terminals of the optical fiber jumper to insert and the terminals at the two ends of the optical fiber jumper are respectively inserted into the plug wire ends of the two rows of optical modules. Eventually, both the patch cord end of the optical module and the terminal of the optical fiber patch cord are secured in the panel assembly 10. The number of the first sockets 111 in each row is 6, and the number of the second sockets 121 in each row is also 6, but when the bracket is manufactured specifically, the number of the first sockets 111 and the second sockets 121 in each row can be adjusted according to actual conditions, and the description of the embodiment should not be interpreted as limiting the number of the first sockets 111 and the second sockets 121.

As shown in fig. 2, the central axis of the tension column 30 is parallel to the second maximum surface 102 of the panel assembly 10. The outer side of the tension column 30 is provided with 6 semicircular ring grooves 31. The tensioning posts 30 are used to tension the optical fiber jumpers. When the optical fiber jumper wire is used, the middle section of the optical fiber jumper wire is wound around the annular groove 31 and is placed in the annular groove 31, so that the optical fiber jumper wire is neatly drawn and cannot shake randomly.

The SFP cage typically has an indicator light thereon that is covered after the stent of this embodiment is used. For this purpose, as shown in fig. 2 and 3, the holder further includes a light guiding long fiber 41 and a light guiding short fiber 42. The light guide long fibers 41 and the light guide short fibers 42 are used for guiding the light of the indicating lamp of the SFP cage to the outside, so that an operator can visually see the working condition indication. Two light guide long fibers 41 are paired, and two light guide short fibers 42 are paired. The light guiding long fiber 41 is disposed at one end on the first largest surface 101 of the panel assembly 10 and at the other end outside the tension column 30, and the light guiding long fiber 41 between the two ends penetrates through the panel assembly 10 and the tension column 30. The light-guiding short fibers 42 extend only through the panel assembly 10. The light guiding short fiber 42 is provided at one end at the first largest surface 101 of the panel assembly 10 and at the other end at the second largest surface 102 of the panel assembly 10. The light guiding long fibers 41 have one row and are arranged at the middle plane between the two rows of the first inserting holes 111. The light guiding short fibers 42 have two rows and are respectively arranged outside the two rows of the first inserting holes 111. The two rows of light-guiding short fibers 42 form a symmetry with respect to the middle plane between the two rows of first receptacles 111. By the structural design, no matter which direction the optical module on the bracket is inserted into the SFP cage, the light guide short fibers 42 and the light guide long fibers 41 can correspond to the indicator lamps of the SFP cage, and blind insertion is convenient to realize.

As shown in fig. 4, the rack is inserted with optical modules 80 and fiber jumpers 90. As shown in fig. 4, the front plate 11 is provided with a screw hole 112 communicating with the first insertion hole 111 at a position corresponding to the first insertion hole 111. The axis of the threaded hole 112 is perpendicular to the central axis of the first socket 111, and the threaded holes 112 correspond to the first sockets 111 one by one. Since the optical modules 80 through which the first sockets 111 in the upper and lower rows penetrate are symmetrical to each other, the screw holes 112 are also arranged vertically symmetrically. A stop screw 113 is screwed into the threaded hole 112, and the stop screw 113 penetrates into the first socket 111 and is used for pressing the optical module 80 in the first socket 111. A fastening screw 114 is further screwed into the threaded hole 112, and the fastening screw 114 is pressed against the limit screw 113 and is used for fixing the limit screw 114.

As shown in fig. 4, the rear plate 12 is provided with through holes 122 in one-to-one correspondence and communication with the second sockets 121. The through hole 122 is used for allowing a foreign object to pass through and press the snap pressing sheet 91 of the terminal of the optical fiber jumper 90, so as to facilitate the detachment of the optical fiber jumper 90. Similarly, the upper row of through holes 122 is symmetrical to the lower row of through holes 122.

As shown in fig. 4, a stepped groove 115 is formed in the middle of the surface of the front plate 11 facing the rear plate 12 in parallel with the arrangement direction of the first inserting holes 111. The port hooks 81 of the optical modules 80 in the upper row and the lower row are buckled in the stepped groove 115.

The structure of this embodiment support can load double optical module 80 and load the corresponding optic fibre wire jumper 90 of pegging graft simultaneously, and once only pegging graft is tested through a plurality of optical module 80 of support assistance during the use, can once only dismantle a plurality of optical module 80 through the support after the test is accomplished, can change the optical module 80 of next batch at once and test, and efficiency of software testing is promoted. And the integration level of the support is high, thereby being beneficial to realizing automatic operation, further reducing the manual participation and improving the efficiency of the whole process.
